AWS CloudFormation accelerates dev-test cycle with adjustable timeouts for custom resources

The article discusses a new feature introduced in AWS CloudFormation, called the ServiceTimeout property for custom resources. It allows customers to set a custom timeout value for the execution of provisioning logic in a custom resource, enabling faster feedback loops during development and testing cycles.

Specifically, the article covers:

• CloudFormation custom resources allow customers to write their own provisioning logic, with CloudFormation executing the logic during stack operations
• Previously, custom resources had a fixed 1-hour timeout, which led to long wait times for code bugs or failures
• The new ServiceTimeout property allows customers to set a custom timeout value for their custom resource
• If the custom resource does not respond within the specified timeout, CloudFormation will fail the execution, providing faster feedback for quicker dev-test iterations
• The ServiceTimeout property is available in all AWS Regions where CloudFormation is available
