Running Apache Kafka® at the Edge Requires Confluent’s Enterprise-Grade Data Streaming Platform

Modern edge computing is transforming industries including manufacturing, healthcare, transportation, defense, retail, energy, and much more-pushing data management to far-reaching data sources to enable connected, low latency operations and enhanced decision making. These new use cases shift workloads to the left-requiring real-time data streaming and processing at the edge, right where the data is generated. But collecting and processing data at the edge presents many challenges, particularly at scale. In this blog, we'll explore common challenges faced when attempting to deploy Apache Kafka® at the edge and how Confluent's enterprise-grade data streaming platform can cost-effectively address these issues and unlock business-required results.

Implementing Apache Kafka at the edge is expensive, introduces power constraints, and often depends on reliable cloud connectivity

Leveraged by more than 80% of the Fortune 100, Apache Kafka has become the de facto open source standard for data streaming-allowing for the collection and stream processing of data, persistently, in real time from a variety of devices at the edge. However, running open source Kafka at the edge can introduce significant challenges, largely-but not exclusively-due to the remote nature of such deployments. These challenges include:

• Managing open source Kafka at the edge is expensive

• Processing capabilities are limited due to far edge hardware constraints

• Reliably connecting the edge to your datacenter or cloud is complex

Costs of managing Kafka: Running Kafka at the edge involves complex deployment and management tasks, requiring robust remote monitoring tools, scalability features, load balancing, storage safeguards, and more. Deployments of this type demand highly skilled Kafka experts to build and support highly scalable environments with necessary features such as support for non-Java programming languages, comprehensive data integrations, advanced stream processing capabilities, robust security controls, and data quality management tools. Without these, organizations face increased total costs, delayed time to value, and lower ROI.

Far edge power constraints: Edge devices, typically leveraging ARM32, x86, and other processors, often have limited power and processing capabilities. This limitation can hinder the performance of Kafka, making it challenging to implement. Upgrading or supplementing edge devices to meet Kafka's demands can be prohibitively expensive, raising significant cost-efficiency concerns for organizations, and limiting processing capabilities in far edge or remote locations.

Reliable cloud connectivity: Edge computing often requires data movement to a centralized system-like a central datacenter or the cloud-for advanced processing and global distribution of data products. Ensuring seamless connectivity and synchronization between multiple Kafka clusters for mission-critical use cases is complex, requiring highly reliable data sharing and consistent replication across environments. Efficiently transferring all transactional data for large-scale processing adds another layer of difficulty, further complicating edge deployments.

Historically, these challenges have forced many businesses to either ignore, simplify, or drop their use of data streaming at the edge. As a result, many enterprises find themselves unable to meet customer expectations for "real-time everything," dependent upon data sourced from everywhere a business spans. This gap hinders their ability to fully leverage the potential of edge computing and stay competitive in a fast-paced market.

Avoid complexities and accelerate innovation with a complete, enterprise-grade distribution of Apache Kafka

Built by the original creators of Apache Kafka, Confluent Platform provides a complete, enterprise-grade data streaming platform that allows businesses to reduce the complexities of open source Kafka and accelerate projects dependent upon real-time data, wherever they are run-at the edge, on premises, in the cloud, or anywhere in between. With Confluent, teams can easily connect, process, and react to all their data in real time while maintaining focus on what matters most: innovation for the business.

With Kafka at its core, Confluent offers a holistic set of enterprise-grade capabilities that come ready out of the box to accelerate time to value and reduce TCO for data streaming. Rather than needing to spend costly development cycles building and maintaining foundational tooling for Kafka internally, you can immediately leverage features built by the world's foremost Kafka experts to hit production quickly and confidently. That means freeing your teams from undifferentiated heavy lifting in order to focus on developing the real-time applications built on top of Kafka that drive your business forward.

Confluent brings a cloud-native experience to your private, self-managed edge environments. You can easily meet and manage any demand with elastically scaling clusters that automate partition rebalances. With tiered storage, you can retain infinite data right within Kafka while cost-effectively separating storage from compute. Additionally, minimize downtime costs and business disruption with clusters deployed across multiple regions.

Confluent comes packed with a set of tools to enhance engineering agility and enable more of your teams to easily build real-time applications dependent upon data streaming. While other Kafka solutions only support the Java client, Confluent provides a broad set of battle-tested, non-Java clients for popular programming languages, including Python, C/C++, Go, and .NET. Data integrations are made easy with an ever-expanding portfolio of 120+ pre-built connectors. Available later this year, Confluent Platform for Apache Flink® -a Flink distribution fully supported by Confluent-will allow Confluent customers to easily leverage stream processing for edge, on-prem, or private cloud workloads with long-term expert support.

Confluent reduces risk and resource investments for Kafka, simplifying operational tasks with enterprise-grade features for DevOps and platform teams.
