Azure Services Overview - To create a Web API on Azure

To create a Web API on Azure, you can use several services depending on your needs. Here are some of the primary options:

Azure App Service:
  • Description: A fully managed platform for building, deploying, and scaling web apps and APIs.
  • Use Case: Ideal for hosting RESTful APIs built with .NET Core, Node.js, Python, Java, etc.
  • Key Features: Auto-scaling, built-in CI/CD integration, custom domain support, and SSL.

Azure Functions:

  • Description: A serverless compute service that allows you to run event-dri
    ven code without managing infrastructure.
  • Use Case: Suitable for creating lightweight APIs that respond to HTTP requests. Good for microservices and when you need a pay-per-execution model.
  • Key Features: Automatic scaling, integration with other Azure services, and pay-as-you-go pricing.

Azure Kubernetes Service (AKS):

  • Description: A managed Kubernetes service for deploying and managing containerized applications.
  • Use Case: Best for complex, containerized microservices APIs requiring orchestration and scaling.
  • Key Features: Automated updates, scaling, and monitoring. Integrated with Azure DevOps for CI/CD.

Azure API Management:

  • Description: A service to manage, publish, secure, and monitor APIs.
  • Use Case: This service is not for hosting the API itself but for managing APIs that may be hosted in App Service, Functions, or elsewhere.
  • Key Features: Rate limiting, API versioning, access control, and analytics.
  • Description: A service to run containers without managing virtual machines.
  • Use Case: Useful for simple, containerized API services where you don't need the full orchestration capabilities of AKS.
  • Key Features: Quick deployment, pay-per-second billing, and integration with Azure services.
Azure Container Instances (ACI):

Recommendation:

  • For a straightforward Web API, Azure App Service is typically the easiest and most effective option.
  • For a serverless and scalable approach, consider Azure Functions.
  • If you're working with containers and need more control, AKS might be the best fit.
