Cloud computing is the latest rage
Technology chatter suggests that cloud computing is the place to be.It's emerged as a very hot trend, along withvirtualization technology and service-oriented architecture (SOA), and many vendors are looking to capitalize on it.
While there are many inherent benefits to cloud technology, the market buzz has created a wealth of misinformation. The result: confusion among organizations that could realize these benefits. And as with any emerging technology, capabilities and best practices remain very much in flux. Pricing models vary from vendor to vendor, standards are still a work in progress, and best practices continue to be identified.
While all this takes place, myths pertaining to cloud computing are beginning to circulate. This article seeks to provide an effective definition and corrects six of the most pervasive myths.
Defining the cloud
Cloud computing is really a convergence of high performance computing architectures, enterprise-scale computing and Web 2.0 data models.It's the next phase of service-oriented IT. In the cloud, you can access and run IT services, but the services can live beyond the corporate firewall.
Cloud computing allows you to deploy systems, applications, and technology resources as services that reside somewhere else within the cloud-a global connected network. It gives you access to the applications, systems, and IT resources of other organizations when you need them.
Cloud services allow you to scale your IT resources quickly and endlessly. Say you need to process more data... you can just add moreCPUs. Say you need to store more data than your current disk capacity allows... just grab additional storage from the cloud. When demand for these resources has passed you can just as quickly and easily scale down.
Lastly, this emerging technologyisn't free. There is a cost tocloud resources.
Now thatwe've given you a defining overview, read the 6 most prevailing myths surrounding the cloud.
