We are using AWS (EC2-classic) and I will migrate our servers to AWS VPC, we will use AuroraDB, too.
Staging ENV has 8servers (Linux Ubuntu 14.04), and on these servers are running RoR & node.js applications. I was thinking to consolidate these servers into one server.
Pros
- easier maintenance
- we will be able to save money (cca $1,5k which I can theoretically spend in production ENV :) )
Cons
- can be harder to troubleshoot of issues on servers
- more apps on one server can theoretically cause more problems
I looked on usage of performance for last couple weeks and we should be OK on based of performance with new server
It is staging ENV, so we dont need high availability for this.
what is your opinion or experience?
