AWS has launched CloudTrail: a resource tracking and user visibility API. CloudTrail records API calls made to AWS accounts and returns log files. CloudTrail records calls across AWS services. Whether you need to track calls made to the AWS Management Console, AWS SDKs, command line tools, Cloud-Formation, or other AWS services; CloudTrail's call history helps increase security analysis, resource change analysis, and compliance.
Cloud orchestration platform provider Engine Yard has released a new "Core API" that will eventually replace its existing API. The new API has been used internally by the company and reached a level of maturity and stability that made the company comfortable making it available to customers.
