Cloud computing has transformed how digital services are built, delivered, and scaled. From streaming platforms and online banking to business applications and data storage, cloud technology powers much of the modern internet.
This article explains what cloud computing is, how it works, and why it plays a critical role in today’s digital ecosystem.
What Is Cloud Computing?
Cloud computing is the delivery of computing resources—such as servers, storage, databases, networking, and software—over the internet instead of local hardware.
Why Cloud Computing Matters
Cloud technology enables flexibility, scalability, and cost efficiency for organizations of all sizes.
How Cloud Computing Works
Cloud providers operate large data centers that host shared infrastructure accessible on demand.
Core Cloud Computing Service Models
Infrastructure as a Service (IaaS)
IaaS provides virtualized computing resources such as servers and storage.
Platform as a Service (PaaS)
PaaS offers development platforms without managing infrastructure.
Software as a Service (SaaS)
SaaS delivers complete software applications via the internet.
