Apache Kafka

Apache Kafka is an open-source distributed event streaming platform used by thousands of companies for high-performance data pipelines, streaming analytics, data integration, and mission-critical applications.

  • High Throughput: Deliver messages at network limited throughput using a cluster of machines with latencies as low as 2ms.
  • Scalable: Scale production clusters up to a thousand brokers, trillions of messages per day, petabytes of data, hundreds of thousands of partitions. Elastically expand and contract storage and processing.
  • Permanent storage: Store data streams safely in a distributed, durable, fault-tolerant cluster.
  • High availability: Stretch clusters efficiently over availability zones or connect separate clusters across geographic regions.

RabbitMQ is one of the most widely deployed open-source message brokers. RabbitMQ is lightweight and easy to deploy on-premises and in the cloud. It supports multiple messaging protocols. RabbitMQ can be deployed in distributed and federated configurations to meet high-scale, high-availability requirements.

  • Asynchronous Messaging: Supports multiple messaging protocols, message queuing, delivery acknowledgment, flexible routing to queues, multiple exchange types.
  • Developer Experience: Deploy with BOSH, Chef, Docker, and Puppet. Develop cross-language messaging with favorite programming languages such as Java, .NET, PHP, Python, JavaScript, Ruby, Go, etc.
  • Distributed Deployment: Deploy as clusters for high availability and throughput; federate across multiple availability zones and regions.
  • Enterprise & Cloud Ready: Pluggable authentication and authorization support TLS and LDAP. Lightweight and easy to deploy in public and private clouds.
