In the not-so-distant past, computing was a hefty affair, confined to colossal mainframes and shared through a cumbersome process known as time-sharing. Fast forward to the present, and we find ourselves in the era of cloud computing, a technological revolution that has reshaped the way we manage and access data.
Cloud computing is the delivery of computing services over the internet, such as storage, servers, databases, networking, software, and analytics. The term “cloud” refers to the abstraction of the complex infrastructure that enables these services. But how did cloud computing evolve to become such a ubiquitous and powerful technology? Explore the timeline of the history and cloud computing evolution, from its origins in the 1950s to its current state and future trends.
1960s
The cloud computing evolution dates back to the 1960s. In this era, users accessed mainframes through Remote Job Entry (RJE), submitting tasks to operators for execution. The nascent stage of cloud computing was marked by an exploration of ways to make large-scale computing power accessible through time-sharing, optimizing infrastructure, platform, and applications.
1960s – 1990
Concepts of time-sharing become popularized, optimizing large-scale computing power through remote job entry (RJE) and the “data center” model.
1961
John McCarthy proposes the idea of “computation being delivered as a public utility” in his speech at MIT.
1969
ARPANET, the precursor to the internet, is developed by the U.S. Department of Defense.
1970s
The 1970s witnessed the proliferation of the “data center” model, where users submitted jobs to operators to run on mainframes. This laid the groundwork for the evolution of computing models. However, it wasn’t until the 1980s that the internet’s foundational technologies, such as TCP/IP and DNS, began to take shape.

1986
The NSFNET backbone expands internet access, fueling the growth of online services and distributed computing.
1989
Tim Berners-Lee proposes the World Wide Web (WWW), laying the foundation for easy access to documents and resources over the internet.
1990s
The term “cloud computing” first appeared in 1994, metaphorically used by General Magic to describe virtualized services. It gained further attention in 1996 when Compaq Computer Corporation outlined a business plan for “cloud computing-enabled applications.” This plan foresaw the potential commercial success of online consumer file storage, leading Compaq to sell server hardware to internet service providers.
1990
Web hosting services like GeoCities and Tripod appear, offering basic web server access for individuals and businesses.
1994
The “cloud” metaphor is introduced by General Magic, describing the universe of places mobile agents in the Telescript environment could go.
1996
Compaq Computer Corporation incorporates “cloud computing” into its business plan, aiming to supercharge sales with cloud-enabled applications. The plan foresees the commercial success of online consumer file storage, leading to Compaq selling server hardware to internet service providers.
1998
Salesforce.com pioneers software as a service (SaaS), delivering CRM applications through the web, challenging traditional installed software models.
1999
AOL acquires Time Warner, signifying the convergence of media and internet technologies, impacting future cloud services.
2000s
The 2000s marked a significant turning point with the establishment of Amazon Web Services (AWS) in 2002. AWS allowed developers to build applications independently, and in 2006, Google released the beta version of Google Docs, emphasizing the collaborative aspect of cloud computing. Amazon expanded its cloud offerings with Simple Storage Service (S3) and Elastic Compute Cloud (EC2) in the same year. Notably, NASA contributed to the movement by developing open-source software for deploying private and hybrid clouds in 2008.
2002
Amazon Web Services (AWS) launches, offering on-demand cloud storage and computing services like S3 and EC2, marking a watershed moment in cloud computing history.
2006

2008
NASA develops the first open-source software for deploying private and hybrid clouds.
2009
Microsoft Azure launches, entering the cloud computing market with its own platform as a service (PaaS) and infrastructure as a service (IaaS) offerings.
2010s
The following decade saw a proliferation of cloud services. Microsoft launched Microsoft Azure in 2010, and collaboration between Rackspace Hosting and NASA gave birth to OpenStack, an open-source cloud software project. IBM introduced the SmartCloud framework in 2011, and Oracle announced the Oracle Cloud in 2012, reflecting the diversification of cloud services catering to different business needs.
