The Information systems infrastructure has undergone evolution to a great extentespecially over the past 3 decades. This brought a huge impact in enterprises and theirservices like paying bills online, Accessing information, connecting with people,monitoring warehouses, etc. made our lives easier today.Information Systems main purpose in the beginning days was to process ElectronicData, EDP. This has changed during years by using computers to process and generatereports at the managerial level helping in business development later introduction ofPc’s to enable decision making processes and ad-hoc request later followed by theinternet boom enabling new ways of communication, conducting business in smart wayand now we have amazing network infrastructure with huge storage computers and toplevel integration across different applications.One such notable evolution is with the Cloud Computing. In the early 1950’s theconcept of mainframe computing was introduced and since it was not supported in thebudget perspective Virtual Machines like VMWare came into existence in few decades.This took mainframe computing to a different level altogether and was an importantelement in communication and information gathering. Then came the virtual privatenetworks by telecommunication companies with much lesser cost using the shared costmethod instead of single connection to each user. This evolution can be seen in levelsas Grid computing ( parallel computing to solve big problems) , Utility Computing (computer resources are offered on a metered service basis) , SaaS (subscribing tonetwork based on application) ,Cloud Computing (anywhere and anytime access).The major milestone of Cloud computing was the introduction of Salesforce.com in1999. The next was Amazon Web Services in 2002 providing services with storagealong with human intelligence through Amazon Mechanical Turk. Later again Amazon’sElastic Compute Cloud (EC2) arrived which enables renting computer to run their ownapplications.Cloud Infrastructure as a Service (IAAS) is one of the emerging trends in the ITinfrastructure. According to Gartner’s predictions the biggest concerns of the IT industryis dependent mainly on enterprise mobility, big data and Cloud computing. IAAS ispreferred among many business due to its availability and convenient cloud servicemanager with hardware, storage, server and other elements with a fee based on usage.In the next couple of years there are chances that agile web-scale architecture mightemerge as the main approach by many.m-Commerce is another emerging trend which might be integrated in IT management.This enable consumers to make purchases irrespective of place and time. There is aninitiative to make the retail sales multi-channel announced during the 98 th Conventionand Annual Exposition of NRF.We can say that as world move forward in IT trends evolving itself we will be amazed atthe new tools and technologies being introduced each day.
