Requirements¶
Juju version¶
The charm currently runs on and is tested against Juju 3.6 LTS.
The minimum supported Juju version is Juju 3.5+.
Recommended hardware¶
The below requirements are a good baseline upon which to size your Charmed Apache Kafka applications, but will not be appropriate for every use-case, based on device, data, network and cost constraints.
Note that while these requirements are recommended for a broad-range of production use-cases, each component can run with much lower requirements for use in staging or test environments.

Note
For production deployments, ensure that all nodes are deployed on separate physical machines and that each component node is in a different availability-zone (AZ) for redundancy.
Supported architectures¶
The charmed-kafka snap currently supports amd64 only. The support for arm64 is in development.
