The primary purpose of the development environment is to support development and unit testing activities. This environment is usually provisioned with the smallest instances to support your developers. In addition, you can use a shared database instance with schema space for each of your developers. Depending on the standards within your organization, you will do daily, weekly, or on-demand deployments in this environment. You may or may not provision for HA or configure auto scaling in your development environment. Typically, the development instances are shutdown at the end of each day and through the weekends. However, during crunch periods these environments are kept running for extended hours.
