A company is running multiple applications on Amazon EC2. Each application is deployed and managed by multiple business units. All applications are deployed on a single AWS account but on different virtual private clouds (VPCs). The company uses a separate VPC in the same account for test and development purposes.
Production applications suffered multiple outages when users accidentally terminated and modified resources that belonged to another business unit. A SolutionsArchitect has been asked to improve the availability of the company applications while allowing the Developers access to the resources they need.
