Software Plus Services (Software + Services) is Microsoft’s philosophy for complementing the software company’s on-premises software offerings with cloud-based remote computing software options. The approach is based on providing the benefits of both traditional physical-based software and Web-based software-as-a-service (SaaS) delivery methods in order to create more effective software solution options for customers.
Microsoft’s Software + Services cloud strategy seeks to strike an ideal balance between the flexibility and interoperability of Web applications and the versatility and increased functionality available with PC-centric applications.
