The first type of service that Azure offers is Infrastructure as a Service (IaaS). In this form of service, you just pay for the computing capacity that you need. For example, suppose that you run a web application on the Internet. You will need a web host that provides you with physical access to the internet. So, what is the cheapest way to access the web?

Well, you can rent a cheap Azure cloud Service Partner dedicated server from an online web host, or you can use a free website hosting service. You can then purchase more you need when you want to use them. For example, you can add memory or processor power to the server when you need it. Azure offers many resources that can be added to IaaS. These include virtual machine instances, storage volumes, networking, security and many others.

The next form of cloud computing that is offered by Azure is Platform as a Service (PaaS). In this form of service, you purchase or lease a software development environment that will provide you with an entire set of software development tools. Once you use the service, the tools are yours to keep. Azure offers a large collection of PaaS services, including web applications, mobile apps, database management systems, and more.
