When you want to run a web application on Azure, several options present themselves. A classic VM, a managed App Service, container-based Container Apps, serverless Functions. The right choice depends on the balance of scale, complexity and cost.
01. Virtual Machines
The classic approach: you run your own Windows/Linux VM. You have full control, but OS patching, security and backup are also your responsibility.
02. App Service
The fastest way to get your ASP.NET, Node.js, Python and Java web applications to the cloud. Auto-scaling, deployment slots, custom domain and SSL management come ready.
03. Container Apps
For container-based applications. The ideal middle ground if you don't want all the complexity of Kubernetes but want the advantages of containers.
04. Azure Functions
Serverless for small functions and event handlers. Azure's equivalent of AWS Lambda.
05. Decision Guide
A short guide:
- Classic ASP.NET / Node.js application: App Service
- Container-based: Container Apps
- Microservices, large scale: AKS
- Serverless, event-driven: Functions
- Custom setup: VM
