Cloud computing is location-independent computing, whereby shared servers provide resources, software, and data to computers and other devices on demand, as with the electricity grid. Cloud computing is a natural evolution of the widespread adoption of virtualization, service-oriented architecture and utility computing. Details are abstracted from consumers, who no longer have need for expertise in, or control over, the technology infrastructure "in the cloud" that supports them.
Cloud computing describes a new supplement, consumption, and delivery model for IT services based on the Internet, and it typically involves over-the-Internet provision of dynamically scalable and often virtualized resources. It is a byproduct and consequence of the ease-of-access to remote computing sites provided by the Internet. This frequently takes the form of web-based tools or applications that users can access and use through a web browser as if it were a program installed locally on their own computer.
Some of the examples of cloud computing that we use regularly is Facebook ,Microsoft Outlook etc.
Cloud Computing is the next big thing in IT after Social networking. Many companies are looking forward to it.
If you are a software developer you are required to work on your system where say the tool is installed which you used for Coding.......Now what cloud computing can do is....it can make a programmer to access that tool from anywhere in the world ...do the coding and save it without security threat.....I know I am being too optimistic and doing such a work is going to be very challenging...........and most of the Big companies like IBM ,HP etc are looking forward to build on this technology of Cloud computing. Cloud computing can also be of great help in the Healthcare sector.Many of the healthcare systems esp. those containing database of the patients are using cloud computing.
Yes Google Docs is also cloud computing...because u r using a service which gives you storage of data...without owning any IT infrastructure.......so basically when you use IT services without owning ur own IT infrastucture such as servers,networks, Firewall etc.....ur using cloud computing
But what about enterprise level softwares like ERP's.They are mostly still on premise ( means that the infrastructure is maintained by the organization only).
and also how secure would be this cloud computing when applied to ERP etc.
also such things have been available from long emails, google docs etc.What is the reason for such popularity of the term cloud computing offlate ?
marketing gimmik ???
The fundamental issue in ERPs is the data storage....which is huge...also data security.......when a company uses ERP.....it is always advisable to have own infrastructure due to security issues....however..if cloud computing take care of this questions then why not................but it is very easy to say.....but a very challenging job to do........When a company say buy SAP it buys all the infrastructure...design ..implementation from the company ..however service providers ..may only provide services........sooner ERP is going to be a old..trend....now people are looking frwd to ERps. in SME segment...as new potential market............ by the technical feasibility with all the concerned issues is what companies like HP ,IBM are investing huge money on...a student like me will not be able to address........atleast for a year....
