Cloud computing, a most buzzing word of today era, is not actually a new technology. It’s just an old technology with new advancements.
Cloud computing have evolved many phrases like grid computing, software-as-a-service, Utility computing and Infrastructure-as-a-service. Cloud computing was first introduced in 1960’s with project “MULTICS”. It was a failed attempt due the lack of communication resources, i.e. public access of internet and because of cheaper and stronger personal computing. At the same time, another project ARPANET have similar ideology. ARPANET, with vision that everyone on the globe to be interconnected and accessing programs and data at any site, from anywhere, explained Margaret Lewis, product marketing director at AMD. “It is a vision that sounds a lot like what we are calling cloud computing.”
After 1960’s, cloud computing pop back during the evolution of web2.0 or you can say at the time of POST. It was the time when internet was publicly available and accessible. personal computing was more cheaper but the data was huge. Big fishes (IT companies ) have large data centres with low utilization. They were looking for an option to utilize the available resources.
After a big silence cloud computing came back with the arrival of Salesforce.com in 1999, which was with the idea of delivering enterprise applications using a simple website. This was the first attempt of SaaS ( Software-as-a-Service).
After Salesforce.com next major development was Amazon web services in 2002, which provided a suit of cloud-based services such as storage, computation and even human intelligence via Amazon Mechanical Turk. After the success of Amazon web services, in 2006 Amazon launched Elastic Compute cloud (EC2) as a web service to rent computers for small-scale companies to run their own application stack.
“Amazon EC2/S3 was the first widely accessible cloud computing infrastructure service,” said Jeremy Allaire, CEO of Brightcove, which provides its SaaS online video platform to UK TV stations and newspapers.
Amazon was the only major cloud service provider until Google and others started browser-based enterprise solutions. In 2009 Google introduced its cloud service named Google Apps. Cloud computing has been emerged with many cloud apps from leading technology giants such as VMware, Oracle and Google. Other key factors that have enabled cloud computing to evolve include the maturing of virtualization technology, the development of universal high-speed bandwidth, and universal software interoperability standards.
UK cloud computing pioneer Jamie Turner adds, “As cloud computing extends its reach beyond a handful of early adopter Google Docs users, we can only begin to imagine its scope and reach. Pretty much anything can be delivered from the cloud.”
With the evolution of virtualization and software such as VMware Workstation (from VMware Inc.) and Virtual Box (from Oracle Corporation; previously from SUN Microsystems), cloud computing is everywhere. Most of the servers are based on virtualized hardware.
Many IT professionals recognise the benefits cloud computing offers in terms of increased storage, flexibility and cost reduction, but still there are many factors (these factors will be discussed in next post) that stops cloud computing to be the Technology of Future.
