This IDC presentation is part 1 of a 2-part series of buyer studies that provides results of a comprehensive survey into U.S. customer buying patterns and adoption of cloud-based outsourcing services across the lifecycle of cloud services including PaaS (platform-as-a-service), TaaS (testing-as-a-service), IaaS (infrastructure-as-a-service) and SaaS (software-as-a-service) by organizations that employ 1,000 persons or more. The survey involved 350 end users. The core focus of this study is on the road map of transformation to cloud-enabled services from traditionally-delivered services (e.g. more labor-centric). In particular areas that this study examined include internal IT environment and timeline of internal transformation to cloud-based delivery; primary buyer and usage of cloud services over the next 5 years; sequence of adoption of cloud services by application and cloud services type; bundling preferences by cloud services types (PaaS, TaaS, IaaS, SaaS); transformational preferences to outsourced private cloud (e.g. pre-built versus transformed) and by application type (e.g. ERP, CRM, salesforce automation); distribution of provider portfolio by provider type (traditional versus "pure-play" cloud provider) and optimal number of cloud providers over the next 5 years. This report will also provide essential guidance for outsourcers and service providers on what strategic issues they need to focus on to support customer transformation to using outsourced cloud services as well as which factors that providers need to consider in their transformation to becoming a cloud provider.
