Oracle Functions is a fully managed, multi-tenant, highly scalable, functions-as-a-service platform. It's built on enterprise-grade Oracle Cloud Infrastructure components and powered by the open source Fn Project serverless platform. Along with Oracle Events, Oracle Functions can deliver powerful capabilities for infrastructure and application automation. Together, they enable services to act automatically based on state changes in infrastructure resources, a common use case for enterprise IT environments.
This post walks through an example of a function that verifies whether a compute instance is tagged correctly when it's provisioned. If the instance isn't tagged properly, the function acts to stop the instance. This practice is common in infrastructure automation; it allows resources to be audited for compliance with internal governance policies as they are created, rather than after.
