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 can 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 shut down at the end of each day and through the holidays and weekends. However, during crunch periods and to support development teams across different time zones, these environments are kept running for extended hours.
