Amazon S3 Service Level Argreement

by alex on October 9, 2007

Amazon Web Service S3(Simple Storage Service) which allows you to store data on what they call the internet cloud now has a Service Level Argreement. The SLA was announced on the AWS blog.

…we commit to 99.9% uptime, measured on a monthly basis. If an S3 call fails (by returning a ServiceUnavailable or InternalError result) this counts against the uptime. If the resulting uptime is less than 99%, you can apply for a service credit of 25% of your total S3 charges for the month. If the uptime is 99% but less than 99.9%, you can apply for a service credit of 10% of your S3 charges.

It's not 5 nines (99.999%) and it's not a lot of compensation if you lose important data, but at least it will provide AWS with the right incentives to keep the service up and running.

Good for Amazon. I hope they extend it to the Elastic Computing Cloud(EC2 is their virtual server service) as well.

Nirvanix has had an SLA from the launch of the company,How long has Amazon S3 been around? Obvious move by Amazon to win back some customers.

I had not heard of Nirvanix before. I took a look and it looks like S3 but with higher prices. I used AWS because of the EC2 service and used S3 as a natural extension. What’s the benefit of using Nirvanix?
