What Is the Best Oracle Cloud Service for Serverless Application Deployment in OCI Essentials Exam?
Preparing for the Oracle Cloud Essentials certification exam? Learn which OCI service — Functions, API Gateway, OKE, or VMware Solution — is designed for running serverless applications, with a clear breakdown of each option to help you answer confidently on exam day.
Question
Which OCI service can be used for running serverless applications?
A. API Gateway.
B. Functions.
C. Oracle Cloud VMware Solution.
D. Oracle Kubernetes Engine (OKE).
Answer
B. Functions.
Explanation
OCI Functions is Oracle’s fully managed, serverless computing service built on the open-source Fn Project. It follows a Function-as-a-Service (FaaS) model where you write small, focused pieces of code that execute only when triggered by an event — such as an HTTP request, a message in a queue, or a database change — and you pay only for the compute time consumed during execution. Unlike API Gateway (which manages and routes API traffic but doesn’t execute application logic on its own), Oracle Cloud VMware Solution (which runs VMware-based virtualized workloads), or Oracle Kubernetes Engine (which orchestrates containerized applications across managed clusters), OCI Functions removes the need to provision, patch, or scale any infrastructure, making it the purpose-built serverless option among the four choices.
