Explanation: 

Detailed explanation-1: -Oracle Cloud Infrastructure (OCI) Functions is a serverless, event-driven service that lets developers build, run, and scale applications without provisioning or managing any infrastructure.

Detailed explanation-2: -Create a Database VM (DBaaS) Enter the details about the system you want to provision, including the system and networking details. You will need to upload your public key for operating system access, and remember to select the Virtual Cloud Network and associated subnet you created previously.

Detailed explanation-3: -With OCI Functions, you can write code in Java, Python, Node, Go, Ruby, and C# (and for advanced use cases, bring your own Dockerfile, and Graal VM). You can then deploy your code, call it directly or trigger it in response to events, and get billed only for the resources consumed during the execution.
