Apache Kafka vs Confluent Kafka: A Comprehensive Guide

In today’s world of real-time data streaming, Apache Kafka and Confluent Kafka have become the go-to platforms for handling large-scale data pipelines. But, many developers and organizations often find themselves confused about the differences between the two. In this blog post, we’ll dive deep into the comparison of Apache Kafka vs Confluent Kafka, discussing their features, use cases, and which one might be the best fit for your needs.

What is Apache Kafka?

Apache Kafka is an open source distributed event streaming platform. It was originally developed by LinkedIn and later made open-source under the Apache Software Foundation. Apache Kafka is designed for high throughput, fault tolerant and scalable messaging. It allows real time data streaming so you can create real time functionality in your app, which helps organizations create applications that can process a lot of data in real-time.

Some of the features that Apache Kafka has given are:

Scalability: Kafka can handle trillions of events every day.
Fault Tolerance: With replication features, Kafka ensures that data is always available, even if failures occur.
Durability: Kafka guarantees message delivery and persistence.

What is Confluent Kafka?

In the below section you will know the basic difference between Apache Kafka vs Confluent Kafka

Confluent Kafka is a commercial platform built around Apache Kafka. Although it is fully compatible with Kafka, Confluent Kafka adds some extra tools, services and enhancements that simplify and extend the capabilities of Apache Kafka. Confluent was created by the creators of Apache Kafka and provides a fully managed Kafka service with enterprise grade features that are rarely found. Confluent Kafka serves as a data streaming platform that includes almost all of Kafka’s functionality and a few other things

Confluent Kafka’s key offerings:

Confluent Control Center: A powerful GUI tool used to monitor Kafka clusters and their health.
Schema Registry: A centralized service that manages Avro, JSON, and Protobuf schemas.
Kafka Connectors: A collection of pre built connectors that help Kafka integrate with databases, file systems, and more.
KSQL: A SQL-based interface used for real-time data stream processing.

Key Differences Between Apache Kafka vs Confluent Kafka

In the below section you will learn what is difference between Apache Kafka vs Confluent Kafka

Enterprise Features and Tools
Apache Kafka: Apache Kafka provides a solid base for building event streaming platforms. However, for enterprise-grade features like monitoring, security, and schema management, you have to either build them yourself or use third-party tools.

Confluent Kafka: Confluent offers advanced enterprise features such as:

Confluent Control Center for monitoring.
Schema Registry for managing data formats.
KSQL for stream processing.
Fully managed connectors for easy integrations with different systems.
If you want to skip the complexity of building these features on your own, Confluent Kafka is the better option.

Deployment and Setup

Apache Kafka: You can deploy Apache Kafka on both your own servers or on cloud infrastructure. But it takes more effort to set up, because you have to configure, manage, and monitor Kafka brokers, consumers, and producers. You have to manage replication, scalability, and fault tolerance manually.
Confluent Kafka: Confluent offers you self managed and fully managed Kafka services Confluent Cloud. Setting up Confluent Kafka is much easier than Apache Kafka, as it has pre-built connectors, dashboards, and enterprise tools that streamline deployment. Confluent manages the infrastructure in Confluent Cloud, which saves both your time and effort.

Scalability

Apache Kafka: Apache Kafka is known for its scalability. You can scale Kafka clusters by adding more brokers to handle increasing data loads. However, scaling Kafka requires manual intervention and a deep understanding of the platform.

Confluent Kafka: Confluent Kafka, especially when using Confluent Cloud, provides automatic scaling. It adjusts resources based on the data load and handles scaling without requiring user intervention.

Support and Community

Apache Kafka: Apache Kafka has a large open-source community, and you can find plenty of documentation, tutorials, and forums to help you with issues. However, support is community-based, and troubleshooting can sometimes take time.

Confluent Kafka: Confluent offers enterprise-level support, including 24/7 assistance, dedicated customer success managers, and more. If you need professional support or want to minimize downtime, Confluent Kafka might be the better option for your organization.

Pricing

Apache Kafka: Apache Kafka is free to use as it’s open-source software. However, you need to factor in the costs of infrastructure, maintenance, and operations. If you’re running Kafka on-premises or in your cloud, you’ll need to manage the costs of servers and resources.

Confluent Kafka: Confluent offers a free version of Kafka with basic features, but advanced features like the Control Center, Schema Registry, and enhanced support are part of their paid plans. Confluent Cloud follows a usage-based pricing model, which may vary depending on the scale of your deployment.

Stream Processing

Apache Kafka: Apache Kafka provides stream processing through Kafka Streams, which allows you to create real time applications directly on Kafka topics so that you can develop real time apps. This is a lightweight library that works well for many use cases.

Confluent Kafka: Confluent offers its own KSQL, which is a SQL based engine for real time stream processing. KSQL simplifies stream processing tasks and is ideal for users who prefer SQL over traditional programming models.

Data Integration
Apache Kafka: Kafka provides Kafka Connect to integrate with various data systems, but you may need to write custom connectors for some use cases. It offers a lot of flexibility but requires more development effort.

Confluent Kafka: Confluent Kafka simplifies data integration by providing a wide range of pre-built connectors. You can integrate with databases, file systems, cloud services, and more, with minimal coding required.

When to Choose Apache Kafka?

If you are on a tight budget and want full control over your infrastructure.
If you have a technical team that is comfortable with managing Kafka clusters and integrating custom solutions.
If you prefer open-source and community-driven software. Here the difference between Apache Kafka vs Confluent Kafka: A Comprehensive Guide based on choose guide

When to Choose Confluent Kafka?

If you need enterprise-grade features like easy monitoring, schema management, and built-in connectors.
If you want to avoid the overhead of managing Kafka infrastructure and prefer a fully managed service.
If you are looking for professional support and faster troubleshooting. Here the difference between Apache Kafka vs Confluent Kafka: A Comprehensive Guide based on choose guide

Final Thought for Apache Kafka vs Confluent Kafka

When comparing Apache Kafka vs Confluent Kafka, the key differences boil down to deployment complexity, enterprise features, support, and pricing. Apache Kafka is an excellent choice if you’re looking for a cost-effective, open-source solution and have the resources to manage it yourself. On the other hand, Confluent Kafka provides enhanced features, integrations, and support that make it ideal for organizations looking for a more streamlined, enterprise-grade solution.

Ultimately, the choice between Apache Kafka vs Confluent Kafka depends on your specific needs. If you want a hands-on experience with full control over your infrastructure, Apache Kafka is perfect. But if you need advanced features, seamless integrations, and enterprise support, Confluent Kafka will be a better fit.

Both platforms are powerful, but understanding your organization’s needs and resources is key to making the right choice!
