Mainframe Era (1950s – 1970s):

The history of cloud computing can be traced back to the era of mainframe computers. Mainframes were large, centralized computers used by businesses and governments to process data and run applications. Users accessed mainframes through terminals, which had limited processing power and relied on the mainframe for computing tasks.

Client-Server Computing (1980s – 1990s):

The emergence of client-server computing marked a shift towards decentralized computing. In this model, servers handled specific tasks, such as storing data or running applications, while client devices, such as PCs, accessed these services over a network. This laid the groundwork for distributed computing, a key concept in cloud computing.

The Birth of the Internet (1990s):

The widespread adoption of the internet in the 1990s laid the foundation for cloud computing. The internet enabled seamless communication and data transfer between devices, paving the way for the delivery of computing services over the internet.

Early Cloud Computing (2000s):

The early 2000s saw the emergence of utility computing and grid computing, precursors to modern cloud computing. These technologies allowed users to access computing resources on-demand, similar to how utilities provide electricity or water.

The Rise of Amazon Web Services (AWS) (2006):

In 2006, Amazon Web Services (AWS) launched Amazon Elastic Compute Cloud (EC2), a groundbreaking service that allowed users to rent virtual servers on which to run their applications. This marked the beginning of the modern cloud computing era.

Expansion of Cloud Services (2010s – Present):

The 2010s witnessed the rapid expansion of cloud services, with major tech companies like Google and Microsoft entering the market with their own cloud offerings. Today, cloud computing has become an essential part of modern computing infrastructure, powering a wide range of applications and services.
