Hello - We'er considering moving our current EC2 Based Stack to Docker. High level topography
consists of 5 EC2 Instances with all of them acting as Master/Data Nodes. We have two More Coordinating nodes that direct traffic to the 5 master/data nodes. The Two coordinating nodes are fronted by an ELB. We do get approximately 1 million documents per day which this setup handles with ease.
A few questions here. Any insights would prove useful in us progressing:
- Does it make sense to setup the master/data nodes as DAEMON (thus ensuring we get only 1 task per Instance mimicing our current 1 Node per instance in the EC2 setup?).
- Will this setup support automatic rollover in case of EC2 AMI Updates (as in at least 1 task/node is remaining alive when others are down during AMI upgrade ?)
