Welcome to IT as a Service For Dummies, IBM Limited Edition. IT as a Service is the emerging technique that gives technology leaders the flexibility of providing the right set of services to the business. The world of IT is changing dramatically. Businesses are increasingly discovering that IT services are becoming the foundation for the customer experience. IT as a Service isnít simply a new delivery model for applications. Instead, IT as a Service is a new approach to providing an array of modular services that are targeted to solve changing business problems. While services can be as straightforward as compute or storage in the cloud, they can also be used to complex solutions. Other services may include microservices or integration services that enable a business to quickly create new solutions to help service customers in a more creative and efficient manner.
