Re: BOSH Windows is GA! (& ACTION REQUIRED: End-of-life for Diego MSI)

Stockley, Jonathan <Jonathan.Stockley@...>

I note that your announcement says "This enables feature parity with BOSH-deployed Linux VMs”.
Does this mean it now supports persistent disk on windows?
Or is this only “feature parity” wrt Diego cells?

Subject: [cf-dev] BOSH Windows is GA! (& ACTION REQUIRED: End-of-life for Diego MSI)

Hi cf-dev,

This is a very exciting email to write! I'm extremely proud to announce that BOSH Windows, the new deployment mechanism for Windows cells, is now generally available!

ACTION REQUIRED: Given that BOSH Windows is now ready to use and fully compatible with Diego, we intend to end-of-life the Diego MSI immediately. More details on this and an explanation for the accelerated timescale are at the bottom of this email.

About BOSH Windows: At this point BOSH Windows has been successfully running 100% of the CI/CD workload for the BOSH Windows and Greenhouse teams for more than a month. The Diego team has also just finished an effort to integrate workers deployed via BOSH Windows in their CI/CD pipeline. In all cases it has held up remarkably well. Given this I'm happy to recommend people move over to BOSH Windows as soon as possible (the cf-deployment "windows-cell" ops file<> should make this extremely simple -- but please note you MUST evacuate any cells that were deployed using the MSI as part of the transition or you WILL have problems in the future).

As well as being based on open standards, BOSH Windows has some other significant benefits:

* We've been able to simplify and modularise the BOSH code base as part of this transition. This enables feature parity with BOSH-deployed Linux VMs

* BOSH Windows uses the exact same agent code as BOSH Linux for running jobs, so when you run jobs you know they run similarly on Windows as elsewhere

I'm immensely proud of the teams that have worked together to deliver this.

DIEGO MSI END OF LIFE: 19/5/2017 - ACTION REQUIRED: Now that BOSH Windows is ready we’re extremely keen to avoid maintaining two deployment methods for any longer than necessary, so we would like to move everyone to BOSH Windows immediately. Doing this on an accelerated timescale is particularly important because Diego intends to remove the global route-emitter in the near future. Due to the release of BOSH Windows, we have not implemented the local route-emitter for MSI cells, which would prevent apps on MSI cells from being routed to once the global route-emitter is removed.

If anyone has huge problems moving off MSI cells now please reach out to me asap and we’ll see what we can do. Either way, we will no longer be supporting MSI cells or accepting pull requests from this point. Unless anyone has a strong reason otherwise (if so please do say!), we will end support for MSI cells on 19/5/2017.

Thanks all very much, and again a huge thanks to the BOSH Windows team!
