In what is likely a surprise to no one, Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) rank, in that order, as the leading cloud infrastructure and platform services (CIPS) providers in the latest Gartner Magic Quadrant report.

The report lauds AWS for its sheer size and scope including its near universal availability and depth of services and support.

“AWS continues to have a commanding lead across many of the CIPS market’s critical dimensions, including total market share and capabilities of offerings,” Gartner wrote on AWS’ strengths. “AWS has the largest share of the worldwide market in IaaS and database PaaS offerings.”

Gartner also commended the cloud giant for being an “exceedingly well-run business from a financial perspective and generates more than 50% of the operating income for all of Amazon.” AWS’ most recent financial results included a 29% year-over-year increase in segment revenues to $10.8 billion.

However, Gartner also noted that AWS’ size is a detriment as concern has been increasing over just how much control the cloud giant has over the market. The research firm cautioned users over the potential for “poor cohesion” across AWS’ wide berth of service offerings and potential for higher costs compared with rivals.

While not quite hitting the broad reach as AWS, Gartner said that Microsoft Azure was a solid choice due to its “complete end-to-end set of solutions related to a broad range of workloads and applications.” These have been bolstered by the cloud provider’s partnerships with other market players like Oracle, SAP, and VMware.

The biggest caution the report levied against Azure was its dearth of “availability zones” that pale in comparison to rivals and lack the depth of services offered by others. “As a result, Gartner continues to have concerns related to the overall architecture and implementation of Azure, despite resilience-focused engineering efforts and improved service availability metrics during the past year.”

Meanwhile, the report tied GCP’s strengths to its association with the open source community, and it specifically mentioned the Kubernetes and TensorFlow groups. Gartner explained that these have “brought developer ‘mind share’ to Google Cloud Platform.” It also applauded GCP for its ability to grow its market share and close “a number of critical capability gaps between GCP and Microsoft Azure.”

Gartner did caution users that Google is still viewed as not serving the enterprise market as thoroughly as its larger rivals, and it has seen its fair share of network outages over the past year that could further erode enterprise confidence.

Outside of the top three, Gartner had Alibaba Cloud, Oracle, IBM, and Tencent Cloud all placed in that order within the “niche players” box.

It tied Alibaba Cloud’s strengths to its strong presence in its home Asia-Pacific (APAC) region, with an especially strong presence in the lucrative China market. But, its growth potential in more Western markets is hindered by ongoing geo-political issues.

Oracle’s long-standing presence in the market has allowed it to construct what Gartner described as “thoughtfully architected, hyperscale cloud architectures that are competitive with the more-established cloud providers.” It did caution that Oracle continues to lack the scale and focus of its larger rivals, with a perplexingly low market share in the public cloud database PaaS market where its history should provide it with an advantage.

IBM’s strengths are also tied to its history, especially with its Power Systems data center offerings. It has also more recently expanded its cloud native and open source potential with the $34 billion acquisition of Red Hat. However, it’s still viewed as working through its integration plans and continues to be troubled by complex platforms tied to its legacy operations.

Tencent Cloud’s “niche-ness” is linked to its heavy focus on the China market, with Gartner stating that the cloud provider only has three regions outside of its home market with more than one availability zone. While the China market is nothing to sneeze at, Tencent’s ties to that market – like Alibaba – could limit its broader appeal.

Gartner did note that its latest four-box ranking differs from previous attempts by now taking into account broader service offerings being pedaled by hyperscalers. These include platform-as-a-service (PaaS), function-as-a-service (FaaS), database PaaS, application developer PaaS, and enterprise-focused private cloud offerings.

“Ultimately, hyperscale cloud providers, and the broad array of services they offer beyond infrastructure-as-a-service (IaaS), have found strategic importance in Gartner’s enterprise clients and the Magic Quadrant needed to evolve to reflect as much,” the report states.
