One such notable evolution iswith the Cloud Computing.
In the early 1950’s the concept of mainframecomputing was introduced and since it was not supported in the budgetperspective Virtual Machines like VMWare came into existence in few decades.This took mainframe computing to a different level altogether and was animportant element in communication and information gathering. Then came thevirtual private networks by telecommunication companies with much lesser costusing the shared cost method instead of single connection to each user. Thisevolution can be seen in levels as Grid computing ( parallel computing to solvebig problems) , Utility Computing ( computer resources are offered on a meteredservice basis) , SaaS (subscribing to network based on application) ,CloudComputing (anywhere and anytime access). The major milestone of Cloudcomputing was the introduction of Salesforce.com in 1999. The next was AmazonWeb Services in 2002 providing services with storage along with humanintelligence through Amazon Mechanical Turk.
Later again Amazon’s ElasticCompute Cloud (EC2) arrived which enables renting computer to run their ownapplications. Cloud Infrastructure as aService (IAAS) is one of the emerging trends in the IT infrastructure. Accordingto Gartner’s predictions the biggest concerns of the IT industry is dependentmainly on enterprise mobility, big data and Cloud computing. IAAS is preferredamong many business due to its availability and convenient cloud servicemanager with hardware, storage, server and other elements with a fee based onusage. In the next couple of years there are chances that agile web-scalearchitecture might emerge as the main approach by many. m-Commerce is anotheremerging trend which might be integratedin IT management. This enable consumersto make purchases irrespective of place and time.
There is an initiative tomake the retail sales multi-channel announced during the 98th Convention and Annual Exposition of NRF. We can say that as world moveforward in IT trends evolving itself we will be amazed at the new tools andtechnologies being introduced each day.
