Strengths: AWS can boast a diverse base of customers running a broad range of use cases, including hosting of mission-critical applications. And having compute capacity many times larger than all of the other ranked providers combined has helped Amazon recruit more than a thousand technology partners to build out its ecosystem.
Gartner also recognized the contribution of Amazon's channel partners offering managed and professional services.
"That ecosystem, along with AWS's training and certification programs, makes it easier to adopt and operate AWS in a best-practice fashion," the report stated.
While fully mature, AWS remains agile, and offers "the richest array of IaaS and PaaS capabilities."
Cautions: While widely perceived as a cost leader, Amazon "is not eager to be the lowest-cost bidder in a competitive situation," according to Gartner.
And because of a complex granular pricing structure, Gartner recommends customers use third-party cost management tools.
"Less-sophisticated customers may become overwhelmed by the range of possible options," Gartner noted. "Training and third-party assistance are strongly recommended."
