As businesses increasingly rely on real-time data processing and streaming, choosing the right managed Kafka service is essential. Confluent and Amazon Managed Streaming for Apache Kafka (MSK) are two popular options for businesses looking to offload the complexity of managing their Kafka infrastructure. In this blog, we will compare Confluent and Amazon MSK, examining their features, pricing, and performance, to help you make an informed decision about which managed Kafka service is best suited for your business needs.
Features and Functionality
Confluent is a fully managed Apache Kafka service developed by the original creators of Kafka. It offers a comprehensive set of features, including:
- Fully managed Kafka clusters with automated provisioning, scaling, and upgrades
- Advanced security features, such as encryption, authentication, and authorization
- Confluent Schema Registry for managing and sharing Avro schemas
- ksqlDB for real-time data stream processing using SQL-like queries
- A rich ecosystem of pre-built connectors for integrating with various data sources and sinks
Amazon MSK, on the other hand, is a managed Kafka service provided by Amazon Web Services (AWS). It offers a more straightforward feature set, focusing on the core Kafka functionality:
- Fully managed Kafka clusters with automated provisioning and patching
- Integration with AWS services, such as AWS CloudTrail, Amazon CloudWatch, and AWS PrivateLink
- Security features, including encryption, authentication, and authorization using AWS IAM
While both Confluent and Amazon MSK provide managed Kafka clusters, Confluent offers a more extensive set of features, including ksqlDB and Schema Registry, which can be beneficial for businesses looking to perform advanced data stream processing and schema management.
Pricing
Confluent offers a pay-as-you-go pricing model, with costs based on the number of Kafka brokers, storage, and data transfer used. Confluent provides a free tier, which includes limited resources, suitable for development and testing purposes. For production workloads, Confluent offers various pricing tiers designed to accommodate different business needs.
Amazon MSK follows a similar pay-as-you-go pricing model, with costs based on the number of Kafka brokers, storage, and data transfer used. Additionally, Amazon MSK offers a free tier, allowing businesses to test the service without incurring any costs.
While both Confluent and Amazon MSK provide flexible pricing options, the specific costs will depend on your business’s usage patterns and requirements. It is essential to carefully review the pricing details for each service to determine which option is more cost-effective for your needs.
Performance and Scalability
Both Confluent and Amazon MSK offer scalable Kafka clusters that can be adjusted to handle increased data loads. Confluent provides auto-scaling capabilities, allowing businesses to automatically adjust their Kafka infrastructure based on their workload requirements. Amazon MSK requires manual intervention to scale up or down the number of Kafka brokers, which may require more planning and management on the part of the business.
In terms of performance, both Confluent and Amazon MSK provide reliable, high-throughput data streaming capabilities. However, businesses that are heavily invested in the AWS ecosystem may find that Amazon MSK offers better performance and integration with other AWS services.
Support and Community
Confluent, being developed by the original creators of Kafka, boasts a large, active community and offers comprehensive documentation, tutorials, and support resources. Additionally, Confluent provides various support plans, including 24/7 support for production workloads, ensuring that businesses have access to expert assistance when needed.
Amazon MSK, as an AWS service, benefits from the extensive support resources provided by AWS, including documentation, tutorials, and support forums.
AWS also offers various support plans, including 24/7 support for production workloads, ensuring that businesses using Amazon MSK have access to expert assistance when needed.

On the other hand, Amazon MSK provides a more straightforward managed Kafka service, focusing on the core Kafka functionality and excellent integration with other AWS services. Businesses already heavily invested in the AWS ecosystem may find Amazon MSK to be a more suitable option.
Ultimately, the choice between Confluent and Amazon MSK will depend on your business’s specific needs and priorities. By carefully evaluating the features, pricing, performance, support, and integration capabilities of each service, you can make an informed decision that best aligns with your data streaming goals.
