Amazon web-services has some trouble for a few hours this morning, causing the blogs to burst with criticism. I say plan for outages - they happen. Read the SLAs. Do your homework and come up with a plan for the following:
- Back up! Back up your Xen EC2 images hourly/nightly/weekly - whatever makes you feel safe. Back up your data to S3 too.
- Don’t do things by hand: Utilize modern deployment tools like Puppet to configure new servers automatically.
- Dynamic DNS: Use DynDNS or other dynamic DNS providers to provide failover to other servers and/or, worst-case, a “We’re working on it!!!” HTML page.
People forget that Amazon’s uptime is still way better than what you’d get in-house and you get that for pennies on the dollar. Shtuff happens - get used to it - plan on it.
