Cloud computing is a style of computing in which scalable and elastic IT-enabled capabilities are delivered as a service using internet technologies. Gartner defines the cloud infrastructure and platform services (CIPS) market as standardized, highly automated offerings, in which infrastructure resources (e.g., compute, networking and storage) are complemented by integrated platform services. These include managed application, database and functions as-a-service offerings. The resources are scalable and elastic in near-real time and are metered by use. Self-service interfaces, including a web-based user interface (UI) and an API, are exposed directly to the customer. The resources may be single-tenant or multitenant, and can be hosted by a service provider or on-premises in the customer’s data center.
Many IT infrastructure and operations leaders want to make their infrastructure services more agile and accessible via self-service. At the same time, they want a simplified, less complex implementation experience for hardware and software. As a result, I&O leaders often acquire infrastructure-centric CMPs with integrated infrastructure systems. IISs offer pre-integrated compute, storage and networking in combination with management software that typically includes IIS configuration management and monitoring. This same pattern extends to hyperconverged integrated systems (HCISs), which have a scale-out design based on commodity components to both reduce the initial acquisition price and enable pay-as-you-grow pricing, but may not offer networking capabilities in the solution.
