Hi All,

Last July, we announced that we would be transitioning the Garden-Linux
backend over to use runC, an implementation of the Open Container
Initiative specification. 9 months on, and we're happy to report that we're
extremely close to shipping v1.0 of what we've decided to call Guardian
[1]. This is a new Garden backend based on runC, and it has the exact same
API as existing versions of Garden-Linux.

We believe Guardian will be feature complete (at least in terms of features
used by Cloud Foundry / Diego) within the next few weeks. Once we hit this
milestone, there is still some integration work and performance testing to
be done, but you should expect to hear from us again in the next few months
with details of a transition plan.

We're also planning to incept the next batch of work for the Garden team
next week. Normally we would wait until Guardian has shipped to do this,
but we have a rare opportunity next week as the whole team will be in the
same location for the first time in six months, and we're going to take
advantage of this to run an inception.

The next batch of work will be focused on security, with the high level
goal that Guardian should be the most secure container management solution
available for multi-tenant workloads. We'll share some notes after the
inception, but please do get in touch in the meantime if you have any
questions or thoughts.

Best,
Will - Garden PM
