The report authors found that leadership in the cloud IT infrastructure services market was correlated to strong in-house software development skills.
This is IHS Markit’s first scorecard for off-premises IT cloud infrastructure services, including infrastructure-as-a-service (IaaS), cloud-as-a-service (CaaS), software-as-a-service (SaaS), and platform-as-a-service (PaaS).
According to Cliff Grossner, senior research director with IHS Markit, the cloud service provider revenue numbers for 2015 are:
- Amazon – $7.9B
- Google – $2.5B
- IBM – $1.4B
- Microsoft – $4.32B
- CenturyLink – $1.16B
- Equinix – $2.02B
- Rackspace – $1.8B
Salesforce also appeared on the report as a challenger. Salesforce provides PaaS with its Salesforce1 platform that provides social and mobile cloud development tool kits. Salesforce PaaS revenue was $931M for 2015.
How does IHS’s off-premises IT cloud differ from the usual reference to “public cloud?” According to the research company, its off-premises IT cloud includes public cloud delivered by a service provider using shared infrastructure, and it also includes hybrid scenarios where enterprises use a combination of off-premises cloud together with applications served from the enterprise’s on-premises private cloud.
The Scorecard evaluated providers based on financials, direct feedback from buyers, provider market share, market share momentum, brand recognition, reputation for innovation, and other benchmarks. Providers were classified as leader, established, or challenger depending on their overall score.
