The findings are based on Forrester’s new report titled “The Partner Opportunity For AWS Marketplace SIs, GSIs And Resellers.” The research firm interviewed 27 representatives of 14 existing AWS Marketplace channel partners with experience collaborating with AWS to build, innovate and scale marketplace practices. Partners include systems integrators, global systems integrators (GSIs), resellers, MSPs and professional services partners. They were mostly global businesses based in North America, Europe and Asia with annual revenue ranging from less than $100 million to more than $25 billion.
