Origin and Evolution Of Cloud Computing

• The roots of cloud computing can be traced from the mid-90s (1960) when Dr. Joseph Carl Robnett Licklider, an American computer engineer who is also called the “father of Cloud Computing”. He introduced the idea of global networking with memos discussing an Intergalactic Computer Network. 
  
• In 1963, DARPA ( the Defence Advanced Research Projects Agency) presented MIT with $2 million for Project MAC. Its basic purpose was to make virtualization a reality in the tech industry. It was also known as a primitive cloud, with two to three people accessing it.
  
• The meaning of virtualization was later shifted to describe the creation of a virtual machine, which will act the same as a full-fledged computer. This idea became word of mouth through the internet, and businesses even started to offer virtual networks as a rentable service.  This idea became so popular in the 1990s that it eventually led to the development of “modern cloud computing” infrastructure.

Cloud Computing in the Late 1990s: 

• In the initial stages. The word cloud was used to express the space between the user and the provider. In 1997, Prof. Ramnath Chellapa of Emory University defined it as a “computing paradigm”, where the boundaries of computing will be determined by economic rationale rather than technical limits alone.” It was also characterized as the first academic definition of cloud computing.
  
• In 1999, Salesforce became a popular example of using cloud computing. They utilized it to pioneer the idea of delivering some of the computer programs to end users. Also, the programs can be accessed and downloaded by anyone with internet access. 

Cloud Computing in the Early 2000s: 

• In 2002, Amazon was the first company to utilize this facility by introducing its web-based retail. They used 10% of their physical server capacity with the cloud computing infrastructure model. Later on, larger giants followed the same steps. 
  
• In 2006, they launched Amazon Web Services,  out of which Elastic Compute Cloud (EC2) offers computers, software and programs for rental to its users. 
  
• In the same year (2006), Google launched its Docs services, which were originally based on two facilities, i-e, Writely & Google Spreadsheets. Microsoft launched Azure, expanding cloud services into software (SaaS) and Platform as a Service (PaaS).  
  
• In 2007, IBM, Google and several universities joined forces to do the research and develop a server farm for research projects needing both fast processors and huge data sets. In the same year, Netflix also introduced its cloud services to stream anywhere. 
  
• In 2008, NASA’s OpenNebula provided its first open-source software for deploying private and hybrid clouds. 

2010 and Beyond: 

• However, private clouds were initiated in 2008 but are still underdeveloped. In 2010, companies like AWS, Microsoft, and OpenStack had functional private cloud solutions.
  
• Security concerns in public clouds drove interest in private clouds.
  
• OpenStack launched an open-source, free cloud in 2010, making private clouds more accessible.
  
• The concept of hybrid clouds was introduced in 2011. Hybrid clouds require interoperability between private and public clouds. Few businesses had the infrastructure to shift workloads between clouds at the time.
  
• In 2011, Cloud servers got more evolved as IBM introduced the IBM SmartCloud framework to support Smarter Planet. Apple launched iCloud, focusing on personal data storage (photos, music, videos). Microsoft started advertising cloud storage, increasing public awareness.
  
• In 2012, Oracle introduced Oracle Cloud, offering IaaS, PaaS, and SaaS solutions. SaaS became widely adopted, with public clouds offering all or select services. CloudBolt developed a hybrid cloud management platform, solving interoperability issues.
  
• In 2013-2014, Organizations began using multiple SaaS providers for HR, CRM, and supply chain management. A strategy evolved to avoid vendor lock-in due to interoperability challenges.
  
• In 2014, Cloud security became a growing industry to address user concerns. Protection against data loss, theft, and leakage improved significantly. Security remains a top priority for cloud users.
  
• In 2016, Cloud computing shifted from being developer-friendly to developer-driven. Developers increasingly relied on cloud tools and services. Cloud providers continued innovating to attract developers with better tools.
