What is the use of OCI Functions?

OCI Functions are specifically designed to execute serverless code in response to events, which makes option B the correct choice. This serverless architecture allows developers to run their application code without managing the underlying infrastructure. Instead of worrying about servers, scaling, or complex deployment pipelines, developers can focus solely on writing functions that are triggered by specific events such as HTTP requests, changes in data, or messages in a queue. This model promotes agility and scalability, allowing for efficient handling of transient workloads, as functions can seamlessly scale up or down based on demand.

The other options describe functionalities that do not align with the primary purpose of OCI Functions. Deploying virtual machines for applications applies more to core compute services rather than a serverless functions framework. Containerization pertains to the packaging of applications and their dependencies, which is handled by Oracle Container Engine for Kubernetes among other services, and not directly by OCI Functions. Managing network traffic routing involves services like Oracle Cloud Infrastructure Load Balancing, which focuses on distributing client requests across compute resources, and is separate from the event-driven aspect of OCI Functions.
