Apache Kafka Benefits & Use Cases

Apache Kafka is arguably one of the most popular open-source stream processing systems today. Used by over 80% of the Fortune 100, it has countless advantages for any organization that benefits from real-time data streaming, event-driven architecture, data integration, or analytics.

Founded by the original creators of Kafka, Confluent is a fully managed Kafka rebuilt as a cloud-native data streaming platform for more elasticity, performance, and scalability.

Quick Intro: What is Apache Kafka?

Apache Kafka is an open-source distributed streaming platform that can simultaneously ingest, store, and process data across thousands of sources. While Kafka is most commonly used to build real-time data pipelines, streaming applications, and event-driven architecture, today, there are thousands of use cases revolutionizing Banking, Retail, Insurance, Healthcare, IoT, Media, and Telecom. used by thousands of companies for low-latency data pipelines, streaming analytics

Apache Kafka originated at LinkedIn in 2011 as a solution for platform analytics for user activity at scale in social networking. The functionality has been extended through open source development across enterprise IT organizations to support data streaming, data pipeline management, data stream processing, and data governance across distributed systems in event-driven architecture. Kafka is open source under an Apache 2.0 license.

One of the major advantages of Apache Kafka is data integration across thousands of microservices with connectors that enable real-time search and analytic capabilities. This enables software development teams to introduce new features to enterprise software according to the specific requirements of their organizational logistics by sector or industry.

Who uses Kafka?


Some of the major brands currently leading Apache Kafka development in enterprise are:

  • Uber
  • Twitter
  • Splunk
  • Lyft
  • Netflix
  • Walmart
  • Tesla

...just to name a few! Read on to learn more about Kafka's benefits and use cases.

Why use it?

Apache Kafka creates an event variable with a record, timestamp, key value for data colocation, and header for metadata code. Events can monitor platform activity from websites and mobile applications or return values from IoT devices in manufacturing and environmental research. Each event receives a unique key value that is never reused and is stored in data archives where they can be processed for use in both real-time and historical analytics.

Kafka Benefits - Why Organizations Adopt Streaming Data Architecture:

The key benefit of Apache Kafka is that organizations can adopt streaming data architecture to build custom software services that store and process “big data” according to the particular requirements of their industry or business model. What is Kafka? Businesses from shipping and logistics can use the same data center architecture as websites, mobile apps, IoT, and robotic devices in daily manufacturing with platform analytics based on event-stream tracking.

Custom programming teams are required to fine tune the Kafka service functionality to the unique needs of each application across sectors in industry, although the processing logic of the software remains the same. This allows companies to share open source code and developer resources for the Kafka platform across projects to accelerate the introduction of new features, platform functionality, and security patches with ongoing peer review.

Some of the main advantages of Apache Kafka for enterprise software development are:

Processing Speed:

Kafka implements a data processing system with brokers, topics, and APIs that outperforms both SQL and NoSQL database storage with horizontal scalability of hardware resources in multi-node clusters that can be positioned across multiple data center locations. In benchmarks, Kafka outperforms Pulsar & RabbitMQ with lower latency in delivering real-time data across streaming dataarchitecture.

Platform Scalability:

Originally, Apache Kafka was built in order to overcome the high latency associated with batch queue processing using RabbitMQ at the scale of the world’s largest websites. The differences between mean, peak, and tail latency times in event message storage systems enable or limit their real-time functionality on the basis of accuracy. Kafka’s broker, topic, and elastic multi-cluster scalability supports enterprise “big data” with real-time processing with greater adoption than Hadoop.

Pre-Built Integrators:

Kafka Connect offers more than 120 pre-built connectors from open source developers, partners, and ecosystem companies. Examples include integration with Amazon S3 storage, Google BigQuery, ElasticSearch, MongoDB, Redis, Azure Cosmos DB, AEP, SAP, Splunk, and DataDog. Confluent uses converters to serialize or deserialize data in and out of Kafka architecture for advanced metrics and analytics. Programming teams can use the connector resources of Kafka Connect to accelerate application development with support for organizational requirements.

Managed Cloud:

Confluent Cloud is a fully-managed Apache Kafka solution with ksql DB integration, tiered storage, and multi-cloud runtime orchestration that assists software development teams to build streaming dataapplications with greater efficiency. By relying on a pre-installed Kafka environment that is built on the best practices in enterprise and regularly maintained for security upgrades, business organizations can focus on building their code without the hardships of assembling a team and managing the streaming dataarchitecture with 24/7 support over time.

Real-time Analytics:

One of the most popular applications of data streaming technology is to provide real-time analytics for business logistics and scientific research at scale to organizations. The capabilities enabled by real-time stream processing cannot be matched by other systems of data storage, which has led to the wide-spread adoption of Apache Kafka across diverse projects with different goals, as well as to the cooperation in code development from business organizations in different sectors. Kafka delivers real-time analytics for Kubernetes with Prometheus integration.

Enterprise Security:

Kafka is governed by the Apache Software Foundation, which provides the structure for peer-reviewed security across Fortune 500 companies, startups, government organizations, and other SMEs. Confluent Cloud provides software developers with a pre-configured enterprise-grade security platform that includes Role-Based Access Control (RBAC) and Secret Protection for passwords. Structured Audit Logs allow for the tracing of cloud events to enact security protocols that protect networks from scripted hacking, account penetration, and DDoS attacks.
