Strengths: Microsoft's vision for Azure's various services involves seamless interoperability with on-premise Microsoft applications and devices. Microsoft is unique in its ability to build an ecosystem of its own products, and the company is aggressively pushing that vision into global markets.
While a distant second to AWS in terms of market share, Microsoft is still far ahead of its smaller competitors and has pledged to keep Azure prices competitive with Amazon.
Cautions: With Microsoft's many built-in advantages, it's easy to forget Azure's IaaS offering is still a newcomer to the market. Enterprises, according to Gartner, have found "significant capability gaps" when it comes to networking and security. The offering also is still very Microsoft-centric, and Microsoft has yet to introduce a software licensing marketplace.
