All the resources that you deployed to AWS lifecycle accounts will remain there for about 4 weeks after starting training. Occasionally, the lifecycle accounts will be cleaned up to remove older resources so please make sure to complete the training within the 4 week period.
We prescribe the Automated WSL install process to unify the Assembly Line experience however as you become more familiar with the Assembly Line, you might decide to use a different development environment. In this case, you may decide to delete the instance of WSL installed for the training sessions. Refer to the Microsoft WSL Documentation on how to remove the WSL instance.
