Using Ejabberd in EC2 as an XMPP server to send real-time information to clients...
How it is possible to set up clustering so that if the load on the server gets too much, Auto Scaling will create a new EC2 instance that is part of the Ejabberd cluster?
The documentation I've read suggests that you must already have the machines and manually configure each new one to be added to the cluster. Surely though you don't have to be running redundant EC2 instances just in case?
回答1:
You'll need to do this manually, however a single ejabberd server can handle quite a lot of traffic. Each server adds a significant amount of available connections to your cluster, so it's not a common task.
That said, I'd really be careful running ejabberd in EC2. I've been doing it for about a year, and we fight mnesia network partitioning pretty regularly. Clustered ejabberd servers don't work very reliably in the EC2 network.

I am installing an infrastructure based on EC2 + ejabberd and have read this post. Do not you recommend? I planned to use as backend mysqlk (in AWS RDS) for tables that store large amounts of data. What do you think?
