Cloud Application Security Memo 3 reduces down time and in hopes to eliminate failure. Unfortunately, that search has yet succeed because failure of resources and applications have always been a part of IT. When a company runs data centers that contain many servers and even more disk drives, resource failure is common along with the software or data stored. Redundancy Protects Against Resource Failure Cloud computing provides a great solution to deal with the disposable resources in place of fixed components, but they still need to remain consistent. Implementing the immutable infrastructure pattern is one way to enable this feature and allows a user to replace the server with one that has the most recent configuration instead of updating the older server. Configuration and coding needs to stay an automated and repeatable process. This includes when deploying resources to different environments or an increase in capacity to the existing system to deal with the extra demand. AWS Bootstrapping, Golden Images or a combination of them both will aid you in keeping the process automated and repeatable with no human error. Bootstrapping can be performed once an AWS resource is launched with default configuration.
