Microsoft's serverless container service for running containers without managing servers. Like ordering takeout containers - you get what you need without owning a kitchen.
Development teams use Container Instances for quick testing and batch processing jobs without long-term infrastructure commitments.
All provide ways to run containers without managing servers. ACI runs containers directly (including multi-container groups) with per-second billing. AWS Fargate runs containers as serverless compute for ECS/EKS. Cloud Run runs stateless HTTP/event-driven containers with automatic scaling to zero. OCI Container Instances runs containers on serverless compute in Oracle Cloud.
