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 run containers without you managing servers. ACI runs container groups directly (often used for short-lived jobs). AWS Fargate runs containers via ECS/EKS. Cloud Run is a fully managed container runtime focused on HTTP/event-driven workloads with autoscaling to zero. OCI Container Instances provides serverless-style container execution on OCI.
