Penske’s Data Streaming Success Story

Penske explored its data streaming journey at the Confluent Data in Motion Tour. Sarvant Singh, Vice President of Data and Emerging Solutions at Penske, explains the company’s motivation clearly: “We’re an information-intense business. A lot of information is getting exchanged between our customers, associates, and partners. In our business, vehicle uptime and supply chain visibility are critical.

This focus on uptime is what drove Penske to adopt a real-time data streaming platform, powered by Confluent. Today, Penske ingests and processes around 190 million IoT messages every day from its vehicles.

Each truck contains hundreds of sensors (and thousands of sub-sensors) that monitor everything from engine performance to braking systems. With this volume of data, traditional architectures fell short. Penske turned to Confluent Cloud to leverage Apache Kafka at scale as a fully-managed, elastic SaaS to eliminate the operational burden and unlocking true real-time capabilities.

By streaming sensor data through Confluent and into a proactive diagnostics engine, Penske can now predict when a vehicle may fail—before the problem arises. Maintenance can be scheduled in advance, roadside breakdowns avoided, and customer deliveries kept on track.

This approach has already prevented over 90,000 potential roadside incidents. The business impact is enormous, saving time, money, and reputation.

Other real-time use cases include:

  • Diagnosing issues instantly to dispatch roadside assistance faster
  • Triggering preventive maintenance alerts to avoid unscheduled downtime
  • Automating compliance for IFTA reporting using telematics data
  • Streamlining repair workflows through integration with electronic DVIRs (Driver Vehicle Inspection Reports)

Why Confluent for Apache Kafka?

Managing Kafka in-house was never the goal for Penske. After initially working with a different provider, they transitioned to Confluent Cloud to avoid the complexity and cost of maintaining open-source Kafka themselves.

“We’re not going to put mission-critical applications on an open source tech,” Singh noted. “Enterprise-grade applications require enterprise level support—and Confluent’s business value has been clear.”

Key reasons for choosing Confluent include:

  • The ability to scale rapidly without manual rebalancing
  • Enterprise tooling, including stream governance and connectors
  • Seamless integration with AI and analytics engines
  • Reduced time to market and improved uptime

Data Streaming and AI in Action at Penske

Penske’s investment in AI began in 2015, long before it became a mainstream trend. Early use cases included Erica, a virtual assistant that helps customers manage vehicle reservations. Today, AI is being used to reduce repair times, predict failures, and improve customer service experiences.

By combining real-time data with machine learning, Penske can offer more reliable services and automate decisions that previously required human intervention. AI-enabled diagnostics, proactive maintenance, and conversational assistants are already delivering measurable benefits.

The company is also exploring the role of generative AI. Singh highlighted the potential of technologies like ChatGPT for enterprise applications—but also stressed the importance of controls: “Configuration for risk tolerance is going to be the key. Traceability, explainability, and anomaly detection must be built in.”

Fleet Intelligence in Action: Measurable Business Value Through Data Streaming

For a company operating hundreds of thousands of vehicles, the stakes are high. Penske’s real-time architecture has improved uptime, accelerated response times, and empowered technicians and drivers with better tools.

The business outcomes are clear:

  • Fewer breakdowns and delays
  • Faster resolution of vehicle issues
  • Streamlined operations and reporting
  • Better customer and driver experience
  • Scalable infrastructure for new services, including electric vehicle fleets

With 165,000 vehicles already connected to Confluent and more being added as EV adoption grows, Penske is just getting started.

The Road Ahead: Agentic AI and the Next Evolution of Event-Driven Architecture Powered By Apache Kafka

The future of logistics will be defined by intelligent, real-time systems that coordinate not just vehicles, but entire networks. As Penske scales its edge computing and expands its use of remote sensing and autonomous technologies, the role of data streaming will only increase.

Agentic AI—systems that act autonomously based on real-time context—will require seamless integration of telematics, edge analytics, and cloud intelligence. This demands a resilient, flexible event-driven foundation. I explored the general idea in a dedicated article: How Apache Kafka and Flink Power Event-Driven Agentic AI in Real Time.

This post does not cover the technical improvements and new features of the 4.0 release, like ZooKeeper removal, Queues for Kafka, and so on. Those are well-documented elsewhere. Instead, it highlights the strategic business value Kafka 4.0 delivers to modern enterprises.

Kafka 4.0: A Platform Built for Growth

Today’s IT leaders are not just looking at throughput and latency. They are investing in platforms that align with long-term architectural goals and unlock value across the organization.

Apache Kafka 4.0 offers four core advantages for business growth:

1. Open De Facto Standard for Data Streaming

Apache Kafka is the open, vendor-neutral protocol that has become the de facto standard for data streaming across industries. Its wide adoption and strong community ecosystem make it both a reliable choice and a flexible one.

Organizations can choose between open-source Kafka distributions, managed services like Confluent Cloud, or even build their own custom engines using Kafka’s open protocol. This openness enables strategic independence and long-term adaptability—critical factors for any enterprise architect planning a future-proof data infrastructure.

2. Operational Efficiency at Enterprise Scale

Reliability, resilience, and ease of operation are key to any business infrastructure. Kafka 4.0 reduces operational complexity and increases uptime through a simplified architecture. Key components of the platform have been re-engineered to streamline deployment and reduce points of failure, minimizing the effort required to keep systems running smoothly.

Kafka is now easier to manage, scale, and secure—whether deployed in the cloud, on-premises, or at the edge in environments like factories or retail locations. It reduces the need for lengthy maintenance windows, accelerates troubleshooting, and makes system upgrades far less disruptive. As a result, teams can operate with greater efficiency, allowing leaner teams to support larger, more complex workloads with greater confidence and stability.

Storage management has also evolved in the past releases by decoupling compute and storage. This optimization allows organizations to retain large volumes of event data cost-effectively without compromising performance. This extends Kafka’s role from a real-time pipeline to a durable system of record that supports both immediate and long-term data needs.

With fewer manual interventions, less custom integration, and more built-in intelligence, Kafka 4.0 allows engineering teams to focus on delivering new services and capabilities—rather than maintaining infrastructure. This operational maturity translates directly into faster time-to-value and lower total cost of ownership at enterprise scale.

3. Innovation Enablement Through Real-Time Data

Real-time data unlocks entirely new business models: predictive maintenance in manufacturing, personalized digital experiences in retail, and fraud detection in financial services. Kafka 4.0 empowers teams to build applications around streams of events, driving automation and responsiveness across the value chain.

This shift is not just technical—it’s organizational. Kafka decouples producers and consumers of data, enabling individual teams to innovate independently without being held back by rigid system dependencies or central coordination. Whether building with Java, Python, Go, or integrating with SaaS platforms and cloud-native services, teams can choose the tools and technologies that best fit their goals.

This architectural flexibility accelerates development cycles and reduces cross-team friction. As a result, new features and services reach the market faster, experimentation is easier, and the overall organization becomes more agile in responding to customer needs and competitive pressures. Kafka 4.0 turns real-time architecture into a strategic asset for business acceleration.

4. Cloud-Native Flexibility

Kafka 4.0 reinforces Kafka’s role as the backbone of hybrid and multi-cloud strategies. In a data streaming landscape that spans public cloud, private infrastructure, and on-premise environments, Kafka provides the consistency, portability, and control that modern organizations require.

Whether deployed in AWS, Azure, GCP, or edge locations like factories or retail stores, Kafka delivers uniform performance, API compatibility, and integration capabilities. This ensures operational continuity across regions, satisfies data sovereignty and regulatory needs, and reduces latency by keeping data processing close to where it’s generated.

Beyond Kafka brokers, it is the Kafka protocol itself that has become the standard for real-time data streaming—adopted by vendors, platforms, and developers alike. This protocol standardization gives organizations the freedom to integrate with a growing ecosystem of tools, services, and managed offerings that speak Kafka natively, regardless of the underlying engine.

For instance, innovative data streaming platforms built using the Kafka protocol, such as WarpStream, provide a Bring Your Own Cloud (BYOC) model to allow organizations to maintain full control over their data and infrastructure while still benefiting from managed services and platform automation. This flexibility is especially valuable in regulated industries and globally distributed enterprises, where cloud neutrality and deployment independence are strategic priorities.

Kafka 4.0 not only supports cloud-native operations—it strengthens the organization’s ability to evolve, modernize, and scale without vendor lock-in or architectural compromise.

Real-Time as a Business Imperative

Data is no longer static. It is dynamic, fast-moving, and continuous. Businesses that treat data as something to collect and analyze later will fall behind. Kafka enables a shift from data at rest to data in motion.

Kafka 4.0 supports this transformation across all industries. For instance:

  • Automotive: Streaming data from factories, fleets, and connected vehicles
  • Banking: Real-time fraud detection and transaction analytics
  • Telecom: Customer engagement, network monitoring, and monetization
  • Healthcare: Monitoring devices, alerts, and compliance tracking
  • Retail: Dynamic pricing, inventory tracking, and personalized offers

These use cases cannot be solved by daily batch jobs. Kafka 4.0 enables systems—and decision-making—to operate at business speed. “The Top 20 Problems with Batch Processing (and How to Fix Them with Data Streaming)” explore this in more detail.

Additionally, Apache Kafka ensures data consistency across real-time streams, batch processes, and request-response APIs—because not all workloads are real-time, and that’s okay.

The Kafka Ecosystem and the Data Streaming Landscape

Running Apache Kafka at enterprise scale requires more than open-source software. Kafka has become the de facto standard for data streaming, but success with Kafka depends on using more than just the core project. Real-time applications demand capabilities like data integration, stream processing, governance, security, and 24/7 operational support.

Today, a rich and rapidly developing data streaming ecosystem has emerged. Organizations can choose from a growing number of platforms and cloud services built on or compatible with the Kafka protocol—ranging from self-managed infrastructure to Bring Your Own Cloud (BYOC) models and fully managed SaaS offerings. These solutions aim to simplify operations, accelerate time-to-market, and reduce risk while maintaining the flexibility and openness that Kafka is known for.

Confluent leads this category as the most complete data streaming platform, but it is part of a broader ecosystem that includes vendors like Amazon MSK, Cloudera, Azure Event Hubs, and emerging players in cloud-native and BYOC deployments. The data streaming landscape explores all the different vendors in this software category:

The market is moving toward complete data streaming platforms (DSP)—offering end-to-end capabilities from ingestion to stream processing and governance. Choosing the right solution means evaluating not only performance and compatibility but also how well the platform aligns with your business strategy, security requirements, and deployment preferences.

Kafka is at the center—but the future of data streaming belongs to platforms that turn Kafka 4.0’s architecture into real business value.

The Road Ahead with Apache Kafka 4.0 and Beyond

Apache Kafka 4.0 is a strategic enabler responsible for driving modernization, innovation, and resilience. It directly supports the key transformation goals:

  • Modernization without disruption: Kafka integrates seamlessly with legacy systems and provides a bridge to cloud-native, event-driven architectures.
  • Platform standardization: Kafka becomes a central nervous system across departments and business units, reducing fragmentation and enabling shared services.
  • Faster ROI from digital initiatives: Kafka accelerates the launch and evolution of digital services, helping teams iterate and deliver measurable value quickly.

Kafka 4.0 reduces operational complexity, unlocks developer productivity, and allows organizations to respond in real time to both opportunities and risks. This release marks a significant milestone in the evolution of real-time business architecture.

Kafka is no longer an emerging technology—it is a reliable foundation for companies that treat data as a continuous, strategic asset. Data streaming is now as foundational as databases and APIs. With Kafka 4.0, organizations can build connected products, automate operations, and reinvent the customer experience easier than ever before.

And with innovations on the horizon—such as built-in queueing capabilities, brokerless writes directly to object storage, and expanded transactional guarantees supporting the two-phase commit protocol (2PC)—Kafka continues to push the boundaries of what’s possible in real-time, event-driven architecture.

The future of digital business is real-time. Apache Kafka 4.0 is ready.

Real-time data streaming with Kafka and Flink enables critical retail media use cases by processing vast amounts of data from customer interactions, inventory updates and advertising platforms. The ability to analyze and act on data instantly allows retailers to optimize ad placements, enhance personalization, and measure the effectiveness of marketing campaigns with unprecedented accuracy. Below are some of the most impactful retail media applications powered by event-driven architectures.

Personalized In-Store Promotions

Retailers can use real-time customer location data, combined with purchase history and preferences, to deliver highly personalized promotions through mobile apps or digital signage. By incorporating location-based services (LBS), the system detects when a shopper enters a specific section of a store and triggers a targeted discount or special offer. For example, a customer browsing the beverage aisle might receive a notification offering 10% off their favorite soda, increasing the likelihood of an impulse purchase.

Dynamic Ad Placement & Bidding

Kafka and Flink power real-time programmatic advertising, enabling retailers to dynamically adjust ad placements and bids based on customer activity and shopping trends. This allows advertisers to serve the most relevant ads at the optimal time, maximizing engagement and conversions. For instance, Walmart Connect continuously analyzes in-store and online behavior to adjust which ads appear on product pages or search results, ensuring brands reach the right shoppers at the right moment.

Inventory-Aware Ad Targeting

Real-time inventory tracking ensures that advertisers only bid on ads for products that are in stock and ready for fulfillment, reducing wasted ad spend and improving customer satisfaction. This integration between retail media networks and inventory systems prevents scenarios where customers click on an ad only to find the item unavailable. For example, if a popular TV model is running low in a specific store, the system can prioritize ads for a similar in-stock product, ensuring a seamless shopping experience.

Fraud Detection & Brand Safety

Retailers must protect their media platforms from click fraud, fake engagement, and suspicious transactions, which can distort performance metrics and drain marketing budgets.

Kafka and Flink enable real-time fraud detection by analyzing patterns in ad clicks, user behavior, and IP addresses to identify bots or fraudulent activity. For example, if an unusual spike in ad impressions originates from a single source, the system can immediately block the traffic, safeguarding advertisers’ investments.

Real-Time Attribution & Measurement

Retail media networks must provide advertisers with instant insights into ad performance by linking online interactions to in-store purchases.

Kafka enables event-driven attribution models, allowing brands to measure how digital ads drive real-world sales. For example, if a customer clicks on an ad for running shoes, visits a store, and buys them later, the platform tracks the conversion in real time, ensuring brands understand the full impact of their campaigns. Solutions like Segment (built on Kafka) provide robust customer data platforms (CDPs) that help retailers unify and analyze customer journeys.

Retail Media as an Advertising Channel for Third-Party Brands

Retailers are increasingly leveraging third-party data sources to bridge the gap between retail media networks and adjacent industries, such as quick-service restaurants (QSRs).

Kafka enables seamless data exchange between grocery stores, delivery apps, and restaurant chains, optimizing cross-industry advertising. For example, a burger chain could dynamically adjust digital menu promotions based on real-time data from a retail partner—if a grocery store’s sales data shows a surge in plant-based meat purchases, the restaurant could prioritize ads for its new vegan burger, ensuring more relevant and effective marketing.

Albertsons’ New Retail Media Strategy Leveraging Data Streaming

Antivirus is NOT Enough: Supply Chain Attack

A supply chain attack occurs when attackers exploit vulnerabilities in an organization’s supply chain, targeting weaker links such as vendors or service providers to indirectly infiltrate the target.

For example, an attacker compromises Vendor 1, a software provider, by injecting malicious code into their product. Vendor 2, a service provider using Vendor 1’s software, becomes infected. The attacker then leverages Vendor 2’s connection to the Enterprise to access sensitive systems, even though Vendor 1 has no direct interaction with the enterprise.

The Anatomy of a Supply Chain Attack in Cybersecurity

Traditional antivirus software is insufficient to prevent such complex, multi-layered attacks. Ransomware often plays a role in supply chain attacks, as attackers use it to encrypt data or disrupt operations across compromised systems.

Modern solutions focus on real-time monitoring and event-driven architecture to detect and mitigate risks across the supply chain. These solutions utilize behavioral analytics, zero trust policies, and proactive threat intelligence to identify and stop anomalies before they escalate.

By providing end-to-end visibility, they protect organizations from cascading vulnerabilities that traditional endpoint security cannot address. In today’s interconnected world, comprehensive supply chain security is critical to safeguarding enterprises.

The Role of Data Streaming in Cybersecurity

Cybersecurity platforms must rely on real-time data for detecting and mitigating threats. Data streaming provides a backbone for processing massive amounts of security event data as it happens, ensuring swift and effective responses. My blog series on Kafka and cybersecurity looks deeply into these use cases.

In the age of digitization, the concept of pricing is no longer fixed or manual. Instead, companies increasingly use dynamic pricing — a flexible model that adjusts prices based on real-time market changes. Data streaming technologies like Apache Kafka and Apache Flink have become integral to enabling this real-time responsiveness, giving companies the tools they need to respond instantly to demand, competitor prices, and customer behaviors. This blog post explores the fundamentals of dynamic pricing, its link to data streaming, and real-world examples of how different industries such as retail, logistics, gaming and the energy sector leverage this powerful approach to get ahead of the competition.

Dynamic Pricing with Data Streaming using Apache Kafka and Flink

What is Dynamic Pricing?

Dynamic pricing is a strategy where prices are adjusted automatically based on real-time data inputs, such as demand, customer behavior, supply levels, and competitor actions. This model allows companies to optimize profitability, boost sales, and better meet customer expectations.

Relevant Industries and Examples

Dynamic pricing has applications across many industries:

  • Retail and eCommerce: Dynamic pricing in eCommerce helps adjust product prices based on stock levels, competitor actions, and customer demand. Companies like Amazon frequently update prices on millions of products, using dynamic pricing to maximize revenue.
  • Transportation and Mobility: Ride-sharing companies like Uber and Grab adjust fares based on real-time demand and traffic conditions. This is commonly known as “surge pricing.”
  • Gaming: Context-specific in-game add-ons or virtual items are offered at varying prices based on player engagement, time spent in-game, and special events or levels.
  • Energy Markets: Dynamic pricing in energy adjusts rates in response to demand fluctuations, energy availability, and wholesale costs. This approach helps to stabilize the grid and manage resources.
  • Sports and Entertainment Ticketing: Ticket prices for events are adjusted based on seat availability, demand, and event timing to allow venues and ticketing platforms to balance occupancy and maximize ticket revenue.
  • Hospitality: Adaptive room rates and promotions in real-time based on demand, seasonality, and guest behavior, using dynamic pricing models.

These industries have adopted dynamic pricing to maintain profitability, manage supply-demand balance, and enhance customer satisfaction through personalized, responsive pricing.

Dynamic pricing relies on up-to-the-minute data on market and customer conditions, making real-time data streaming critical to its success. Traditional batch processing, where data is collected and processed periodically, is insufficient for dynamic pricing. It introduces delays that could mean lost revenue opportunities or suboptimal pricing. This scenario is where data streaming technologies come into play.

  • Apache Kafka serves as the real-time data pipeline, collecting and distributing data streams from diverse sources. For instance, user behaviour on websites, competitor pricing, social media signals, IoT data, and more. Kafka’s capability to handle high throughput and low latency makes it ideal for ingesting large volumes of data continuously.
  • Apache Flink processes the data in real-time, applying complex algorithms to identify pricing opportunities as conditions change. With Flink’s support for stream processing and complex event processing, businesses can apply sophisticated logic to assess and adjust prices based on multiple real-time factors.

Dynamic Pricing with Apache Kafka and Flink in Retail eCommerce

Together, Kafka and Flink create a powerful foundation for dynamic pricing, enabling real-time data ingestion, analysis, and action. This empowers companies to implement pricing models that are not only highly responsive but also resilient and scalable.

Clickstream Analytics in Real-Time with Data Streaming Replacing Batch with Hadoop and Spark

Years ago, companies relied on Hadoop and Spark to run batch-based clickstream analytics. Data engineers ingested logs from websites, online stores, and mobile apps to gather insights. Processing took hours. Therefore, any promotional offer or discount often arrived a day later — by which time the customer may have already made their purchase elsewhere, like on Amazon.

With today’s data streaming platforms like Kafka and Flink, clickstream analytics has evolved to support real-time, context-specific engagement and dynamic pricing. Instead of waiting on delayed insights, businesses can now analyze customer behavior as it happens, instantly adjusting prices and delivering personalized offers at the moment. This dynamic pricing capability allows companies to respond immediately to high-intent customers, presenting tailored prices or promotions when they’re most likely to convert. Dynamic pricing with Kafka and Flink can create a much better seamless and timely shopping experience that maximizes sales and customer satisfaction.

Here’s how businesses across various sectors are harnessing Kafka and Flink for dynamic pricing.

Is Apache Kafka a Database? No. But…

No, Apache Kafka is NOT a database. Apache Kafka is a distributed streaming platform that is designed for building real-time data pipelines and streaming applications. Users frequently apply it for ingesting, processing, and storing large volumes of event data in real time.

Apache Kafka does not provide the traditional features associated with databases, such as random access to stored data or support for complex queries. If you need a database for storage and retrieval of structured data, you would typically use a database system like MySQL, PostgreSQL, MongoDB, or others with Kafka to address different aspects of your data processing needs.

However, Apache Kafka is a database if you focus on cost-efficient long-term storage and the replayability of historical data. I wrote a long article about the database characteristics of Apache Kafka. Read it to understand when (not) to use Kafka as a database. The emergence of Tiered Storage for Kafka created even more use cases.

In this blog post, I want to focus on one specific feature of Apache Kafka for long-term storage and query functionality: Compacted Topics.

What is a Compacted Topic in Apache Kafka?

Kafka is a distributed event streaming platform, and topics are the primary means of organizing and categorizing data within Kafka. “Compacted Topic” in Apache Kafka refers to a specific type of Kafka Topic configuration that is used to keep only the most recent value for each key within the topic.

Apache Kafka Log Compaction
Source: Apache

In a compacted topic, Kafka ensures that, for each unique key, only the latest message (or event) associated with that key is retained. The system effectively discards older messages with the same key. A Compacted Topic is often used for scenarios where you want to maintain the latest state or record for each key. This can be useful in various applications, such as maintaining the latest user profile information, aggregating statistics, or storing configuration data.

Here are some key characteristics and use cases for compacted topics in Kafka:

  1. Key-Value Semantics: A compacted topic supports scenarios where you have a key-value data model, and you want to query the most recent value for each unique key.
  2. Log Compaction: Kafka uses a mechanism called “log compaction” to ensure that only the latest message for each key is retained in the topic. This means that Kafka will retain the entire history of changes for each key, but it will remove older versions of a key’s data once a newer version arrives.
  3. Stateful Processing: Compacted topics are often used in stream processing applications where maintaining the state is important. Stream processing frameworks like Apache Kafka Streams and ksqlDB leverage a compacted topic to perform stateful operations.
  4. Change-Data Capture (CDC): Change-data capture scenarios use compacted topics to track changes to data over time. For example, capturing changes to a database table and storing them in Kafka with the latest version of each record.

Intersport stores all articles in Compacted Topics, i.e., with no retention time. Article records can change several times. Topic compaction cleans out outdated records. Only the most recent version is relevant.

A model comprises several SKUS as a nested array:

  • An SKU represents an article with its size and color
  • Every SKU has shop based prices (purchase price, sales price, list price)
  • Not every SKU is available in every shop

Accurate Stock Information across the Supply Chain

Intersport and DCCS presented their important points and benefits of leveraging Kafka. The central integration hub uses compacted topics for storing and retrieving articles:

  • Customer facing processes demand real time
  • Stock info needs to be accurate
  • Distribute master data to all relevant sub system as soon as it changes
  • Scale flexible on high load (shopping weekends before Christmas)

Providing the right information at the right time is crucial across the supply chain. Data consistency matters, as not every system is real-time. This is one of the most underestimated sweet spots of Apache Kafka combining real-time messaging with a persistent event store.

Log Compaction in Kafka does NOT Replace BUT Complement other Databases

Intersport is an excellent example in the retail industry for persisting information long-term in Kafka Topics leveraging Kafka’s feature “Compacted Topics“. The benefits are simple usage, cost-efficient event store of the latest up-to-date information, and fast key/value queries, and no need for another database. Hence, Kafka can replace a database for some specific scenarios, like storing and querying the inventory of each store at Intersport.

A smart factory organizes itself without human intervention to produce the desired products. Data integration of IoT protocols, data correlation with other standard software like MES or ERP, and sharing data with independent business units for reporting or analytics is crucial for generating business value and improving the OEE. This blog post explores how data streaming powered by Apache Kafka helps connect and move data to the cloud at scale in real-time, including a case study from BMW and a simple lightboard video about the related enterprise architecture.

From Smart Factory to Cloud with Data Streaming

The State of Data Streaming for Manufacturing in 2023

The evolution of industrial IoT, manufacturing 4.0, and digitalized B2B and customer relations require modern, open, and scalable information sharing. Data streaming allows integrating and correlating data in real-time at any scale. Trends like software-defined manufacturing and data streaming help modernize and innovate the entire engineering and sales lifecycle.

I have recently presented an overview of trending enterprise architectures in the manufacturing industry and data streaming customer stories from BMW, Mercedes, Michelin, and Siemens. A complete slide deck and on-demand video recording are included:

This blog post explores one of the enterprise architectures and case studies in more detail: Data streaming between edge infrastructure (like a smart factory) and applications in the data center or public cloud.

What is a Smart Factory? And how does Data Streaming help?

Smart Factory is a term from research in manufacturing technology. It refers to the vision of a production environment in which manufacturing plants and logistics systems primarily organize themselves without human intervention to produce the desired products.

The technical basis is cyber-physical systems, i.e., physical manufacturing objects and virtual images in a centralized system. Digital Twins often play a crucial role in smart factories for simulation, engineering, condition monitoring, predictive maintenance, and other tasks.

In the broader context, the Internet of Things (IoT) is the foundation of a smart factory. Communication between the product (e.g., workpiece) and the manufacturing system continues to be part of this future scenario: The product brings its manufacturing information in machine-readable form, e.g., on an RFID chip. This data controls the product’s path through the production system and the individual production steps. Other transmission technologies, such as WLAN, Bluetooth, color coding, or QR codes, are also being experimented with.

Data streaming helps connect high-volume sensor data from machines, PLCs, robots, and other IoT devices. Integrating and pre-processing the events with data streaming is a prerequisite for data correlation with information systems like the MES or ERP (that might run at the edge or more often in the cloud). The latter is possible in real-time at scale with stream processing. The de facto standard for data streaming is Apache Kafka and its ecosystems, like Kafka Stream and Kafka Connect.

BMW Group: Data from 30 Smart Factories Streamed to the Cloud

BMW Group needed to make all data generated by its 30+ production facilities and worldwide sales network available in real-time to anyone across the global business.

The data ingested by BMW from its smart factories into the cloud with data streaming enables simple access to the data for visibility and new automation applications by any business unit.

The Apache Kafka ecosystem facilitates the decoupling between logistics and production systems. Transparent data flows and the flexibility of building innovative new services are possible with this access to events from everywhere in the company.

BMW Smart Factory

Stability is vital in manufacturing across the supply chain. This begins with Tier 1 and Tier 2 suppliers up to the aftersales and service management. Direct integration from the shop floor to serverless Confluent Cloud on Azure ensures a mission-critical data streaming environment for data pipelines between edge and cloud.

The use case enables reliable data sharing across the logistics and supply chain processes for BMW’s global plants.

Lightboard Video: How Data Streaming Connects Smart Factory and Cloud

Here is a five-minute lightboard video that describes how data streaming helps with the integration between production facilities (or any other edge environments) and the cloud:

IoT and Edge are not contradictory to Cloud and Data Streaming

The BMW case study shows how you can build reliable real-time synchronization between smart factories and cloud applications. However, there are more options. For more case studies, check out the free “The State of Data Streaming in Manufacturing” on-demand recording or read the related blog post.

MQTT is combined with Kafka regularly if the use case requires supporting bad networks or millions of IoT clients. Another alternative is data streaming at the edge with highly available Kafka clusters on industrial PCs, e.g., for air-gapped environments, or embedded single Kafka brokers, e.g., deployment in a machine.

Humans are still crucial for the success of a smart factory. Improving the OEE requires a smart combination of software, robots, and people. Augmented Reality leveraging Data Streaming is an excellent example. VR/AR platforms like Unity enable remote services, training, or simulation. Apache Kafka is the foundation for real-time data sharing across these different technologies and interfaces.
