Azure: On Premises vs IaaS vs PaaS vs SaaS

Azure cloud model is generally divided into two: Infrastructure as a Service (IaaS) and Platform as a Service (PaaS).

The difference is how much you have to manage in each service. The more you have to manage, the more you have to pay.

Difference Between Azure Web App and Cloud Service

When I first getting started on Microsoft Azure, I was confused between these two: Azure Web Site and Web Role.

Azure Web Site is one of many Azure services while Web Role is an instance running behind Azure Cloud Service, another service offered by Azure. Since then, Azure Web Site has been changed to Azure Web App.

Basically, the difference is the control you have and portion you have to manage in each service.

Azure Cloud Service, Web Role in this case, gives you more control, but with more control, comes greater responsibility. See this graph below:

Introduction to Azure Services

Microsoft Azure is evolving universe. Couple years ago, there were only less than 15 services. Today, there are hundreds and Microsoft keeps adding more so expect even more to come.

Generally, the services are divided into the following group. There more than what is listed here, but these are the main groups.

  • Compute
  • Data Management
  • Networking
  • Mobile
  • Messaging and Integration
  • Backup
  • Identity and Access
  • Big Data

See below graph to get some idea which service belongs to which group. Again, these are generally idea, not every service and group are listed here.

To get more detail on Azure Services and its groups, check out this Azure infographic from Microsoft.

Architecture

Now, what do all these components mean to you as a developer? Each component is a tool and you can use it as a building block to your application, be it a web, mobile or windows application. To give you some ideas, this is what your typical application architecture would look like using Azure Platform.

Open World

What’s really amazing about Microsoft Azure is Microsoft has opened up Azure for ecosystem other than Microsoft. If you are MEAN stack developer, you can deploy MongoDB, Express, AngularJS and Node.js in Azure. You can even deploy MySQL, write PHP code or spin up Linux virtual machine in Azure. Yes, it’s now Microsoft Azure and not WIndows Azure anymore because it doesn’t just belong to Windows or .Net developers, but all kind of developers.

The Future

Azure is huge and it is the future. If you haven’t got your hand in Azure, roll up your shirt sleeves and get dirty now. And if you care to read more, head out to Introducing Microsoft Azure.
