Amazon EC2 consideration - redundancy and elastic IPs -


i've been tasked determining if amazon ec2 should move our ecommerce site to. use amazon s3 lot of images , files. cost go $20/mo our host costs, sell our server few thousand dollars. came because right there no procedures in place if happened our server.

how reliable amazon ec2? redundancy good, don't see in faq , it's problem on our current system i'm looking solve.

are elastic ips beneficial? sounds point dns ip , on amazon's end, reroute ip address ec2 instance instance , running if first 1 failed.

i'm aware of scalability, it's redundancy , reliability i'm asking about.

at work, i've had 20-40 instances running @ times on year. think we've had 1-3 alert emails come amazon suggesting terminate , boot instance (presumably because detecting possible failure in underlying hardware). we've never had instance go down suddenly, seems rather good.

elastic ip's amazing , part of solution. other part being able rapidly bring new instances. i've learned shouldn't care instances going down, it's more important use proper load balancing , able bring commodity instances quickly.
