Simply described, cloud computing is the supply of different computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the internet, or “the cloud.” This model offers economies of scale, flexible resources, and faster innovation, making it a crucial component of contemporary IT infrastructure. The way that people and organizations access and manage their data, apps, and infrastructure has been totally transformed by cloud computing.
What is Cloud Computing?
Cloud computing offers computing services on-demand, giving both individuals and businesses flexibility, scalability, and cost-effectiveness in place of owning and maintaining physical infrastructure on-site. It does this by enabling users to access computing resources like servers, storage, databases, software, and networking via the internet.

Key Characteristics of Cloud Computing
- On-demand Self-Service: Users are able to distribute computer resources as needed without the help of service providers.
- Wide Network Access: A variety of devices, including computers, smartphones, and tablets, may access services over the internet.
- Resource Pooling: Multi-tenant models, which are used by cloud providers, pool resources across several clients and dynamically allocate and reallocate them in response to demand.
- Rapid Elasticity: Resources may be quickly scaled up or down to meet shifting demands.
- Measured Service: Cloud computing uses a pay-as-you-go pricing model, where usage is monitored and billed based on resource consumption.
Types of Cloud Computing
- Software as a Service (SaaS): Provides software applications online through subscription services (e.g., Google Workspace, Salesforce);
- Platform as a Service (PaaS): Offers environments and platforms for application development, testing, and deployment (e.g., Heroku, Google App Engine);
- Infrastructure as a Service, or IaaS, provides virtualized computer resources, such storage, and virtual computers, via the internet (e.g., AWS, Microsoft Azure).
- Public Cloud: Services are hosted on a provider’s infrastructure and shared among multiple clients.
- Private Cloud: For increased control and security, a single business uses dedicated infrastructure.
- Hybrid Cloud: The hybrid cloud combines public and private clouds to allow for the interchange of data and applications.
