We are moving from VPS to VPS in search of un-interrupted service for our Limesurvey instances. To that end, we are considering a cloud install to benefit from the (assumed) redundancy. My review of some of the AWS third-party Limesurvey providers suggests that it is perhaps not possible/not simple to maintain an instance of Limesurvey on AWS in a way where it would not be modified by auto-updates. Is this correct? What we basically need is the cloud but not the automatic source code updates which appear to be part of such services (e.g. Bitnami). I'd appreciate your feedback.

I am also interested in any experience by others.

Did anyone use Amazon Web Services (AWS) for huge Limesurvey project which required lots of resources?

Which cloud provider offers running a duplicate instance of server X so in case of problems you can easily switch to such a copy/backup system?
