description Azure Container Instances Overview
Azure Container Instances is a cloud service from Microsoft Azure that provides fast and simple compute for running containers without requiring virtual machine provisioning. It allows users to run a container directly on the Azure platform, abstracting away the underlying operating system and orchestration layers. This makes it suitable for brief, task-based workloads like image processing or continuous integration jobs that need to start instantly.
Users are billed per second for the compute resources consumed during execution.
help Azure Container Instances FAQ
What is Azure Container Instances used for?
Azure Container Instances runs containers directly in Microsoft Azure without requiring the user to provision or maintain a virtual machine. It is suited to short-lived jobs, simple services, testing, and burst workloads that do not need a full Kubernetes cluster.
How is Azure Container Instances different from AKS?
ACI runs individual containers or container groups with minimal orchestration overhead, while Azure Kubernetes Service provides a Kubernetes control plane for deployments, services, scaling, and cluster-wide workloads. ACI is simpler for a single container, whereas AKS is designed for multi-service Kubernetes applications.
Can Azure Container Instances run more than one container together?
Yes, ACI supports container groups, allowing multiple containers to share a lifecycle, network, and storage context. This is useful for a main application container paired with a sidecar such as a logging or proxy container.
Does Azure Container Instances provide persistent storage?
ACI containers are otherwise ephemeral, but they can mount supported Azure storage such as Azure Files for data that must survive a restart. The storage configuration must be declared and secured separately from the container image.
