While putting together our research, we adopted IDC's method of dividing the cloud market into three distinct pillars: infrastructure-as-a-service (IaaS), software-as-a-service (SaaS) and platform-as-a-service (PaaS).
We then examined the six vendors we believe are symbolic of these three strands of the cloud market. For IaaS, Microsoft, Amazon and Google; for SaaS, Salesforce and Workday; and ServiceNow for PaaS.
For each vendor, we used partner locator tools on their corporate websites to identify their highest-certified channel partners across seven geographical regions: the UK, France, Germany, Benelux, the Nordics, Italy and Spain.
We define the top-level cloud partners for each vendor, in each region, as the following:
Microsoft Gold-level Cloud Platform partners
Amazon AWS Premier and Advanced partners
Google Google Cloud Platform Premier partners
Salesforce Salesforce Platinum partners
ServiceNow Gold-level Sales and Services partners
Workday Services partners
Partners score five points for each top-level vendor certification in each geographic region. Advanced AWS partners receive three points per region.
The overall score displayed represents the total score for all five geographic regions, taking their certification level with all six cloud vendors into account.
All information has been gathered through partner locator tools included on each vendor's website.
Some say performance, others say money but it may be systems and processes that carry the day
