Tim, I like Varnish's vcl flexibility, but not the debugging aspects. Still, +1, but could you elaborate on how you see:
* Services communicate with each other - via varnish as well or directly? * Do you see routing varnish layer as non-caching, only to forward request to the second tear service-specific varnish instance that will actually perform caching? * Will there be any problems separating services into separate, non mutually trusted clusters? * service management - varnish would only indicate overall health of the service. What about service-specific real time monitored values (if needed), logs, controlling service instances. Any thoughts on generalizing that infrastructure? Lastly, semi related - my service will also need a node.js lib to access MW api. How should we manage common libs like that? Thanks!
