I'm assuming Redis to Go is currently hosted on EC2; will that be relocated to the Rackspace Cloud? If so will that affect latency for users on Heroku, for example?
Racker here from the team that worked on this. We are going to continue running Redis To Go for AWS customers and we understand how important low latency is to Redis users. The same goes for ObjectRocket (the MongoDB service we acquired last month) on availability to US-East and US-West on AWS.
Hey, one of the RedisToGo guys here. Before any production hosting we will do plenty of benchmarking between redis servers on Rackspace and Heroku applications.
If you have specific questions, email ben@redistogo.com. Thanks for being a customer!
