Amazon Web Services remains the top IaaS public cloud computing provider, offering the widest breath of services of any vendor in the market, Gartner concluded in its annual Magic Quadrant report.
In addition to having a broad range of cloud-based services, AWS also has the largest capacity to handle cloud-based workloads. Its cloud operation is estimated by Gartner to be five times larger than a dozen of its top competitors in the market combined. "AWS is the overwhelming market share leader," the report reads. "It is a thought leader; it is extraordinarily innovative, exceptionally agile and very responsive to the market. It has the richest IaaS product portfolio, and is constantly expanding its service offerings and reducing its prices."

[FROM THE ARCHIVES:Do you believe in Magic Quadrants?]
Each year Gartner compiles its Magic Quadrant for public cloud vendors by examining the estimated 15 largest market players based on estimated market share, then it ranks them based on their understanding of market needs and the company's ability to execute.
In addition to the breadth and depth of services, AWS also has a robust partner ecosystem with leading technology providers offering its services through Amazon's cloud, including some of the biggest systems integrators. Gartner does warn of some cautions when using AWS services though, including complexity around its pricing and support offerings. Individual AWS offerings are rarely bundled, which can complicate purchasing choices.
No other company is really close to Amazon in terms of its offerings, according to Gartner, but there are a variety of niche players. Outsourcer CSC, for example, receives high marks in the report and is named as the only other leader in the market. Based on VMware's suite of cloud computing offerings, CSC has a very different enterprise-focused model compared to Amazon though, Gartner says. "(CSC) has a solid platform that is attractive to traditional IT operations organizations that still want to retain control, but need to offer greater agility to the business and are willing to embrace data center transformation," Gartner says. Amazon, in comparison is more of an out-sourcing play, with a limited on-premises or "private cloud" option for customers to deploy on their own premises.
Microsoft and Rackspace are listed in the "visionaries" category, while telco-oriented providers Verizon Terremark and Savvis are in the "challengers" quadrant, along with Dimension Data. Joyent, Tier 3, Virtustream, Fujitsu, SoftLayer (now owned by IBM), GoGrid, HP and IBM are considered "niche players" by Gartner.
