If you care about uptime you should really get off EBS (and services that depend on it like ELB and RDS). Having a network between your disks and your CPU make outages like this one inevitable.

What do you recommend as an alternative for hosting large DBs on?
- jacquesm 13y ago
  Define 'large'. Up to 80T can be done in one box these days with up to 32 cores right next to it. Not cheap but fairly reliable. You'll still need to replicate off-site.

    So are you thinking along the lines of Hetzner?
    - jacquesm 13y ago
      Sure. I've never used the cloud, I simply can't make the business case for it. Traffic or storage will kill it every time.

  Use ephemeral disks on EC2 and a good distributed database like Cassandra or Riak. These scale well as your data grows and allow you to lose individual nodes without losing data (in sane configurations).
- eikenberry 13y ago
  +1 to the use of Riak. It is great. But if you are stuck using Postgresql or similar you put your live servers on Ephemeral instances and put one (unused otherwise) slave on EBS so you can snapshot it for backups. And you need at least 2 ephemeral systems so you have a slave to fail over to.

    No need to use ebs/snapshots for backups. Use wal-e and/or pg_receivexlog. Ideally run pg_receivexlog on a server at a different provider so that if amazon cancels your account your data is up-to-the-second recoverable.

  Joyent. Your compute and disks are colocated. Separation of compute and disks is a sure way to cause pain.

    I can't easily get a feel for Joyent's pricing. Is it comparable/cheaper than AWS or?
