Well if you are talking about the transition I think we are going to do it this way - Existing cluster out of any VPC -> DC1 - New VPC cluster, with subnet private + public -> DC2 - Add / Rebuild DC2 - Switch clients from DC1 to DC2 - Remove DC1 - Switch client inside the VPC - Remove public VPC s

A general thought, if you're using AWS for this, I'd strongly recommend you consider using OpsWorks and custom chef recipes for your node deployment if its an option for you. The easy of provisioning new nodes without the need for snapshotting is certainly worth the hassle, and there are already s

I was making assumptions (sorry!), namely the goal to switching to vpc was getting "backend resources" (like cassandra) off the public internet. Will On Thursday, June 5, 2014, Alain RODRIGUEZ wrote: > I think you can define VPC subnet to be public (to have public + private > IPs) or private on

I don't think traffic will flow between "classic" ec2 and vpc directly. There is some kind of gateway bridge instance that sits between, acting as a NAT. I would think that would cause new challenges for: -transitions -clients Sorry this response isn't heavy on content! I'm curious how this thr

Using 2.0.x, we hit https://issues.apache.org/jira/browse/CASSANDRA-2380 when deploying in a VPC. We worked around this by adding a hostname in /etc/hosts. Apart from that, nothing specific. We use only internal ip's, no public ip's and no broadcast etc. It works very well. /Johan From: Alain
