Say, if a key business service is down, then it has to be restored in a timely manner. With Amazon S3, restoring a process is pretty fast compared to Amazon Glacier. Now that we know about the availability of services we can calculate the total available percent of a given solution. And you can literally select an additional region for backup half a world away. There are two main key metrics to remember: 2. If the availability of a service is not known then it can be computed by the Mean time between failures (MTBF) and the Mean time to recover (MTR). It outlines best practices to improve your DR processes, from minimal investments to full-scale availability and fault tolerance, and describes how AWS services can be used to reduce cost and ensure business continuity during a DR event. Amazon VPC allows you to provision a private, isolated section of the AWS cloud. #10. For example, you can use cross-region replication for S3.
