You can now automatically recover instances for Amazon EC2

In yet another sign that the big cloud players of Google, Amazon and Microsoft have moved on from just storage price cuts are in the midst of a feature war, Amazon laid out the details of a new auto recovery tool for Amazon EC2, the company explained in a blog post on Monday.

The tool claims to make it possible for EC2 instances to automatically spin up when internal system checks discover that something is hampering those instances. These problems could include a “loss of network connectivity, loss of system power, software issues on the physical host, and hardware issues on the physical host,” the blog post states.

Now, when a hardware issue impedes one of your EC2 instances, you can automatically reboot that instance, which should contain all the necessary configuration details like the instance ID and the IP address. The new instance can also be rebooted onto new hardware if the situation warrants.

Amazon auto recovery

The auto recovery feature is currently only available to users running the C3, C4, M3, R3, and T2 instance types in the AWS US East region, but Amazon plans to “make it available in other regions as quickly as possible.” Users can set parameters and alerts in CloudWatch to enable auto recovery. There is no extra charge for auto recovery but regular charges for CloudWatch apply.

Currently, it doesn’t seem like Microsoft’s Azure has a similar feature. I asked Microsoft and will update this post if I hear back.

Google Cloud has Live Migration, which means it doesn’t require auto recovery, according to Scalr founder Sebastian Stadil. However, he sees Amazon’s auto recovery being useful to remedy potential software issues.

“Advanced cloud users have been tying their monitoring to fault recovery for a while now, using either homegrown software or off the shelf software like Scalr/RightScale, and they can now use Amazon as an additional choice,” he wrote in an email.
