Azure App Service, Azure Container Apps, and AKS can all run production workloads, but they fit different teams and operational models.
App Service is often the simplest path for web applications and APIs. It is mature, easy to operate, and works well for many .NET and Node.js workloads. If the team wants stable hosting without managing container orchestration, App Service is still a strong option.
Container Apps fits teams that want container packaging, scale-to-zero options, background workers, event-driven workloads, and less Kubernetes operational burden. It can be a good middle ground for product teams.
AKS provides the most control but also the most operational responsibility. It may be right for complex platforms with strong DevOps capability, multiple services, custom networking, or platform engineering requirements.
The decision should consider release process, observability, traffic patterns, cost, team skill, and future operations. Choosing the most powerful platform is not always the best architecture decision.
