Cloud infrastructure is defined by ISO as "a service model for delivering computing assets, such as processing power, storage, and networking, via the network, characterized by resource elasticity, self-management, and pay-per-use metering." This concept is ubiquitously termed "the cloud."

== Defining Attributes == In 2011, NIST codified five fundamental attributes essential to cloud systems. The precise definitions provided by NIST are:

Self-service provisioning on demand: Consumers possess the autonomy to unilaterally procure necessary computational resources (like compute time or disk space) automatically, bypassing the need for direct intervention from the service provider for each allocation request. Ubiquitous network accessibility: Services are reachable across the network using standardized access methods, supporting a wide array of endpoint devices (including smartphones, tablets, laptops, and desktop workstations). Resource consolidation: The supplier aggregates computing assets to service numerous consumers via a shared, multi-tenant architecture, dynamically allocating and reallocating physical and virtual components based on fluctuating demand. Rapid scalability: Capabilities can be instantly expanded or contracted, sometimes automatically, to match demand fluctuations with immediacy. From the consumer's perspective, available resources often seem infinite and accessible in any quantum at any moment. Usage-based metering: Cloud platforms inherently feature systematic monitoring and optimization of resource consumption across abstraction layers relevant to the specific service offered (e.g., I/O operations, CPU cycles, network throughput, active accounts). This detailed reporting ensures transparency regarding utilization for both provider and consumer. By 2023, ISO had subsequently refined and augmented this foundational set of characteristics.

== Historical Context == The conceptual roots of cloud computing trace back to the 1960s, emerging from early innovations in remote job entry (RJE) and time-sharing systems. This epoch primarily relied on the "data center" paradigm, where users submitted batch jobs to dedicated operational staff managing centralized mainframe systems. This period was marked by intense R&D focused on maximizing accessibility to expensive computing power through optimized infrastructure utilization, platform abstraction, and application efficiency gains for the end-user. The pictorial representation of virtualized services as a "cloud" originated in 1994, employed by General Magic to depict the conceptual space reachable by its mobile Telescript agents. This visual idiom is attributed to David Hoffman, an associate specializing in communications at General Magic, acknowledging its pre-existing application within telecommunications and network diagrams. The term "cloud computing" gained significant mainstream traction in 1996 following the development of a strategic business blueprint by Compaq Computer Corporation outlining its future vision for the internet and computing infrastructure.
