Introduction

    Cloud computing has transformed the way businesses and individuals store, process, and access data. With the advent of the cloud, companies no longer need to maintain on-premises servers or worry about scaling and managing their own infrastructure.

    In this article, we will discuss the various stages of the cloud computing life cycle and how they have changed the landscape of the technology industry.

What is Cloud Computing?

    Cloud computing refers to the delivery of computing services over the internet. These services can include servers, storage, databases, networking, s/w, and analytics. The cloud allows individuals and businesses to access these services on demand, without the need for physical infrastructure or IT personnel.

The Birth of Cloud Computing

    Cloud computing can be traced back to the early days of the internet, when companies began to offer web-based applications. These applications were hosted on remote servers and accessed through a web browser, paving the way for the concept of s/w as a service (SaaS).

    In the early 2000s, Amazon launched its Elastic Compute Cloud (EC2) service, which allowed businesses to rent virtual servers on-demand. This marked the beginning of the infrastructure as a service (IaaS) model, which gave businesses the ability to scale their infrastructure on demand.

Cloud Computing Evolution

Over time, cloud computing has evolved into three distinct models: IaaS, PaaS, and SaaS.

• Infrastructure as a Service (IaaS)

IaaS provides businesses with access to virtualized computing resources over the internet. This includes servers, storage, and networking components. With IaaS, businesses can scale their infrastructure on demand and pay only for what they use.
