Probably should have led with this section, honestly. AWS Service Catalog is a service that lets you create and manage catalogs of approved IT resources — CloudFormation templates, basically — that your teams can then launch on their own. Think of it like an internal app store for infrastructure. Instead of filing a ticket and waiting three days for someone to provision a database, developers can browse the catalog, pick the database template that matches their needs, fill in a few parameters, and launch it themselves.
