Amazon's S3 storage service is growing up and adopting a Service Level Agreement (SLA).

In a blog post, Amazon Web Services (AWS) detailed its SLA, which defines a minimum level of performance and imposes penalties if S3 (all resources) doesn't deliver. Amazon noted that formalizing the SLA was the result of customer feedback--and a lot of customers asking for one.

The details:

Effective Oct. 1, S3 commits to 99.9 percent uptime monthly. If S3 fails (via a service unavailable or internal error message) and delivers uptime of less than 99 percent the customer can apply for a service credit of 25 percent. If uptime is between 99 percent and 99.9 percent you can apply for a credit of 10 percent of S3 charges.

A few points to ponder:

  • Kudos for Amazon for creating and SLA. Over time most Web services will offer one.
  • Notice that we're talking 99.9 percent uptime, not the 99.999 percent that enterprises have come to expect. The message: S3 is a fine service, but a big company can expect to outsource its storage needs to the cloud.

  • 99.9999999999999?

    Lol, I've worked in a number of enterprises and though everyone loves to talk smack about high uptime the number of systems that actually hit just 99.9% (taking into account planned and unplanned downtime) are very rare. Sure, if you're VISA, but that's not the class of business Amazon Web Services are aimed at. If you're a company under about $1B, 99.9% is about as good as you'll be able to swing yourself.

  • 99.9 = 44 minutes/30 days

    44 minutes of maintenance every 30 days seems reasonable to me.

    Several major outages over the past year, no customer service, and now a SLA, what an obvious move against Nirvanix who offers 24/7 customer support, and a SLA. Nice try Amazon :-(
