One key decision is if you want to allow application teams to β€œbring your own image”.

However, most application teams don’t want to bother with this and use images already provided in the cloud. There are two main implementation approaches for this

  • use cloud-provider managed virtual machine base images, maybe applying a policy to restrict them to a subset of available images (e.g. only allow CentOS, Ubuntu)

  • provide β€œgolden images” managed by your organizations

The golden image approach has a few advantages, e.g. when it comes to wiring up existing server management infrastructure like SOC Integration. It’s however quite a bit of work, considering cloud-specific specialties (kernel extensions for hypervisor support, cloud-init scripts etc.)

Currently no tool implementations documented. Contributions welcome!
