Azure offers three distinct containerisation services: Azure Kubernetes Service (AKS) for complex workloads requiring Kubernetes control, Azure App Service for straightforward web apps and APIs with minimal management, and Azure Container Apps for serverless, event-driven microservices. Choosing the right service depends on the specific needs of the workload, team expertise, and desired level of control. New cloud-native projects often benefit from starting with Container Apps for its balance of simplicity and power.
