AWS EC2 is a scalable, reliable and low-priced offering from Amazon for the user’s virtual computation or hosting needs. AWS EC2 instances can be launched or terminated any time. However, there may be a probability that the user may terminate the production instance by accident. To overcome the above mentioned problem, AWS provides a functionality called termination protection. Once enabled, the user cannot terminate the instance from the console or the command line API.

The present guide demonstrates how to enable termination protection for an instance.

In case of a disaster we would like to make sure that our applications are still up and running, while taking advantage of our failover hosting/cloud provider. The Disaster Recovery (DR) architecture is driven by the criticality of applications and data. The decision regarding what to back up and deploy eventually translates into ongoing costs that can be extremely significant. Every IT organization has its own high level policy guidelines. These policies are eventually translated into the policy deployed for each of the different applications the enterprise runs. The CIO and its team need to make sure they define both the high level policies and the actual budget that can be spent for DR matters.
