OS Support by Platform and Version
==================================

The following matrix shows which Operating Systems, Platforms, and Containers / Instance Engines are supported with which versions of Scylla.

Scylla requires a fix to the XFS append introduced in kernel 3.15 (back-ported to 3.10 in RHEL/CentOS).
Scylla will not run with earlier kernel versions. Details in `Scylla issue 885 <https://github.com/scylladb/scylla/issues/885>`_.

.. note::

   Scylla Open Source supports x86_64 for all versions and aarch64 starting from Scylla 4.6 and nightly build. In particular, aarch64 support includes AWS EC2 Graviton.

   For Scylla Open Source **4.5** and later, the recommended OS and Scylla AMI/IMage OS is Ubuntu 20.04.4 LTS.
