Microsoft’s offering, Windows Azure, has evolved into an environment that supports IaaS and PaaS models. As a result of adding full IaaS capabilities, as well as fleshing out its private cloud strategy, the vendor now provides the onramps that are making PaaS much more approachable for enterprises. It has also recently added Windows Azure Mobile Services, a cloud mobile back-end service offering that supports multiple clients beyond its own mobile client strategy. Its presence in other cloud environments (for example, SaaS through Dynamics CRM Online and Office 365, including SharePoint Online) also contributes to the vendor’s broad cloud strategy (2014, Gartner).
Microsoft is a large and diversified technology vendor that is increasingly focused on delivering its software capabilities via cloud services. Its Azure business was previously strictly PaaS, but Microsoft launched Azure Infrastructure Services (which include Azure Virtual Machines and Azure Virtual Network) into general availability in April 2013, thus entering the cloud IaaS market (2014, Gartner)..
