Which OCI service is best suited for running serverless applications?

Oracle Functions is specifically designed for running serverless applications. It allows developers to build, run, and scale applications without the need to manage the underlying infrastructure. This service follows a Function as a Service (FaaS) model, enabling the execution of code in response to events, which is a fundamental characteristic of serverless architecture.

With Oracle Functions, developers can focus on writing code without worrying about provisioning servers or managing container orchestration, which are common concerns with traditional application hosting. The service automatically scales to handle varying workloads, which allows businesses to accommodate traffic spikes without conflict or downtime.

In contrast, the other services mentioned do not fit the serverless paradigm. Streaming is focused on real-time data processing and analytics. Virtual Cloud Networks deal with networking capabilities and configurations, while the Audit service is primarily concerned with monitoring and logging activities within the OCI environment. Therefore, when considering which service is best suited for serverless applications, Oracle Functions stands out as the optimal choice.
