Defining Cloud Computing: Key Concepts and Terminology
Cloud computing represents a transformative technological approach where computing services are delivered over the internet, enabling organisations to access powerful digital resources without maintaining complex physical infrastructure. According to the National Institute of Standards and Technology (NIST), cloud computing is a model providing ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources.
Core Service Models
Understanding cloud computing requires grasping its fundamental service models, which determine how resources are delivered and managed:
- Infrastructure as a Service (IaaS): Provides virtualized computing resources over the internet, allowing businesses to rent servers, storage, networks, and operating systems
- Platform as a Service (PaaS): Offers a complete development and deployment environment in the cloud, enabling developers to build and run applications without managing underlying infrastructure
- Software as a Service (SaaS): Delivers software applications directly through the internet, eliminating the need for local installation and maintenance
Deployment Strategies
Businesses can choose from multiple cloud deployment strategies based on their specific requirements. Our comprehensive guide on cloud computing explores these strategies in greater depth:
- Public Cloud: Services provided by third-party providers and accessible to anyone via the internet
- Private Cloud: Infrastructure dedicated to a single organisation, offering enhanced security and control
- Hybrid Cloud: Combines public and private cloud environments, providing flexibility and optimised resource allocation
By understanding these fundamental concepts, organisations can make informed decisions about leveraging cloud technologies to enhance operational efficiency, scalability, and technological agility.
The table below compares the three primary cloud computing service models to highlight their basic function, management responsibilities, and typical use cases in a business environment.
| Service Model | Main Focus | Provider Manages | Typical Business Uses |
|---|---|---|---|
| Infrastructure as a Service (IaaS) | Virtual hardware, storage, networking | Servers, storage, networking | Hosting websites, data storage, virtual machines |
| Platform as a Service (PaaS) | Application development environment | Infrastructure plus OS, middleware | App development, testing, deployment |
| Software as a Service (SaaS) | Ready-to-use software applications | Everything: hardware, software | Email, CRM, office tools, collaboration |
The Importance of Cloud Computing for Today’s Businesses
According to McKinsey research, cloud computing represents a strategic imperative for modern businesses seeking competitive advantage and technological resilience. By transforming traditional IT infrastructure, cloud technologies enable organisations to achieve unprecedented operational efficiency, scalability, and innovation potential.
