Two municipal developers work on separate feature branches for a parks reservation API. Both need to exercise SAM resources without overwriting the shared team development stack. What pattern should they use?
Select an answer to reveal the explanation.
Short Explanation
Shared kitchen, two chefs, one stove—somebody burns dinner. Spin up a short-lived SAM stack per branch so each feature can cook alone. Email turn-taking and forced merges just invite stomping.
Full Explanation
Creating isolated temporary environments for concurrent development testing prevents feature branches from colliding on shared resources. Ephemeral SAM/CloudFormation stacks scoped to a branch or pull request give each developer a disposable environment that can be torn down after review. Serializing on one shared stack or delaying all AWS deploys until production removes that isolation and slows safe integration testing.
