The Development of Cloud
Cloud computing is the result of a gradual evolution where previously occurring phenomenon of grid computing, virtualization, application service provision (ASP) and Software as a Service (SaaS). The concept of unified computing resources through global network itself began in the sixties. When it appears "a Intergalactic computer network" by Licklider, J.C.R. is responsible for the development of ARPANET (Advanced Research Projects Agency Network) in 1969. He had a goal in which every single human being in this world can be connected and can access the programs and data from any site, anywhere. According To Margaret Lewis, Director Of Marketing Of Products AMD. "The ideals that sounds similar to what we now called cloud computing." Other computing experts also provided a additions to this concept, including John McCarthy who offered ideas about network computing will be the public infrastructure, just like the service bureaus which has been around since the sixties.
Since the sixties, cloud computing has grown side by side with the development of the Internet and the Web. However, due to changes in technology are considerable bandwidth in the 1990s, the Internet was first developed than cloud computing. And now we can see that the main drivers of cloud computing is because of the Internet revolution. One of the stepping stones that is a pretty drastic is by the existence of Salesforce.com in 1999, which is the originator of the first enterprise applications run over the Internet. The next development was the rise of Amazon Web Services in 2006, where it bring the Elastic Compute Cloud technology (EC2), that is a web services system that allows smaller companies and individuals to rent a computer or server, so that you can run the application on their computers.
Another great leap rock coming in 2009 with Web 2.0 reached its peak. Google and others are starting to offer browser-based applications for large companies, such as Google Apps. "The most important contribution of cloud computing is the emergence of the" killer apps "of the ruler of technologies like Microsoft and Google. When the company sends a service in a form that is easy for consumption, the effect of acceptance into a very wide ", according to Dan Germain, Chief Technology IT provider Cobweb Solution. "The other main factors influencing the development of cloud computing among other visual technology is the development of universal high-speed bandwidth and universal software", according to Jamie Turner, the pioneers of computing cloud. Turner added, "cloud computing has been widespread until the user`s Google Doc. We can only imagine how large the scope is already accomplished. Anything can be done and delivered through the cloud ".
Migration to the Cloud
A lot of IT knowing the advantages of cloud computing in terms of high storage flexibility and cost savings ", according to Songnian Zhou, Chief Executive Officer of Platform Computing. But he added that the Director IT still has concerns with respect to their corporate data security in the cloud.
Experts agree that cloud computing will change the landscape of computing today. Andreas Asander, Vice-principal of product management at virtualization security specialist from Clavister said that at a time when security concerns have been resolved then the service of cloud computing will allow the company to expand its infrastructure, increase capacity on demand, or to outsource the entire infrastructure, resulting in greater flexibility, as well as a selection of resources that are more diverse and significant cost reductions.
