# Apache Kafka

## Description

Apache Kafka is an **event streaming platform**.

Apache Kafka combines three key features to enable you to implement your end-to-end event streaming use cases with a single, proven solution:

* To publish (write) and subscribe (read) event streams, including continuous import/export of your data from other systems.
* To store event streams permanently and reliably, for as long as you like.
* To process event streams as they occur or retrospectively.

And all this functionality is delivered in a distributed, highly scalable, elastic, fault-tolerant and secure way.

## Platform as a Service

Apache Kafka is deployed on site in **cegedim.cloud** data centers.

**cegedim.cloud** guarantees the same level of service as the Compute offer: instance deployment, operational maintenance, flexibility, security and monitoring are all provided by our experts.

The deployment of a minimum 3-node cluster in version 4.1.1 is available in self-service in ITCare. This topology is ready for production with :

* a minimum of 3 brokers distributed over several availability zones
* 3 dedicated controllers distributed over several availability zones

Delivered clusters are secured for both inter-broker and client <-> broker communications, with SASL\_SSL :

* SSL for the transport layer
* SASL SCRAM-SHA-256 for authentication and authorization

Sizing can be configured to suit your needs.
