Software Updates ("Maintenance")

A Tetrate Istio distribution is a build of the Community Istio Distribution that is supported and maintained by Tetrate. It is built from the official, open-source Istio Software, and a set of base software images that are selected and maintained by Tetrate.

Each Tetrate Istio distribution release is supported and maintained by Tetrate for up to 14 months:

  • The Istio software and base images are supported by Tetrate (community and Enterprise technical support) for 14 months
  • The Istio software is maintained by Tetrate (updates, bugs and security fixes) in line with Istio maintenance, typically 7 months. Additionally, critical security fixes are backported to earlier supported releases where possible
  • The base images are maintained by Tetrate (updates, bugs and security fixes) for 14 months
