In today’s digital-first world, cloud computing serves as the backbone of innovation, scalability, and digital transformation. From startups to global enterprises, organizations rely on the cloud to store data, host applications, and expand effortlessly—without the burden of managing physical infrastructure.
What Is Cloud Computing?
Cloud computing is the delivery of computing services—such as servers, storage, databases, networking, software, analytics, and intelligence—over the internet (the “cloud”). Instead of purchasing and maintaining physical servers, businesses access technology resources on-demand and pay only for what they use.
In simple terms, cloud computing allows you to rent computing power rather than buy it.
Types of Cloud Computing
There are three primary models of cloud computing services, often called Cloud Service Models:
- Infrastructure as a Service (IaaS) : Provides virtualized computing resources over the internet.
- Platform as a Service (PaaS) : For building and deploying applications without managing infrastructure.
- Software as a Service (SaaS) : Complete software delivered over the web.
Cloud Deployment Models
- Public Cloud :Shared infrastructure via third-party providers.
- Private Cloud : Dedicated setup for one organization.
- Hybrid Cloud : Mix of public + private.
