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."
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 centre 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.
The IaaS market for cloud computing is rapidly evolving, but it represents the fastest-growing need among Gartner clients. "As each provider has unique offerings, the task of sourcing their services must be handled with care." Most of the vendors included have Service-Level Agreements (SLA) that ensure the cloud will have 99.95% uptime some even guarantee up to 99.999%.
Gartner warns that security remains a major issue with cloud computing, with the extent of security measures from each provider varying significantly. While a vendor may provide some base-level of security, in many circumstances such as with AWS it's up to the customer to select what additional security features they want. The same is generally true with enterprise-class support, which is offered as an option for customers if they choose from many providers, like AWS.
Customers are using the cloud for more complex workloads now compared to a year ago. Gartner recommends using cloud services for purposes such as test and development, hosting cloud-native applications, e-business hosting, enterprise applications, general business applications and batch computing depending on the provider.
