The practice of continuous integration ensures that code is frequently merged into a central repository, where it is automatically built and tested.
It is also vital to regularly test disaster recovery methods to ensure that data can be recovered during a loss. These are some standard practices to ensure the highest level of data protection in the cloud. When you divide a VPC into subnets, you can segment the resources based on functionality or security needs.
