VaaS -


VaaS enables you to manage cluster(s) of Varnish servers from one place, via a web GUI or a REST API. Information about your Varnish servers and their backends, directors and probes is saved into a database. It is then used to automatically generate and distribute VCLs.

Why we wrote it

We got tired of having to edit VCLs manually, storing them under version control and waiting for puppet to distribute them. As our SOA architecture grew, we found ourselves doing it more and more. So we wrote VaaS. Now each team can administer their service's backends by themselves. And they don't have to wait 30 minutes for puppet to distribute the change. It is applied instantly on all Varnish servers.
