What is Azure Container Instances?

Azure Container Instances (ACI) offers a fast and simple way to run containers in Azure without managing any virtual machines or orchestrators. It's a serverless container execution service that allows you to quickly deploy individual containers for tasks like running background jobs, building simple applications, or for testing container images before deploying to a more complex orchestration system like Kubernetes. ACI is often used for scenarios where you need a container to run briefly and then terminate, or when you want to avoid the overhead of managing a full container orchestration environment.
