As the scuffles between PC vs. Mac and IE vs. Firefox is raging on, there is another battle being carried on that is somewhat unobserved. It is legacy computing vs. Cloud computing. If you are ignorant of these terms, here is an overview.
Cloud Computing is a hosted service over the internet. It is a technology that uses the internet and central remote servers in order to keep up facts and figures, and applications. Today it is getting priority because the project application was too overstuffed that it required too much maintenance and support. You didn’t pay for what you used, but for the whole features that came up with the software even if you need a small percentage of the features. It lets the consumers and businesses use applications without installation and access their personal files on any computer with internet access. This technology allows for much more well-organized computing by integrating data storage, processing and data transmission rate. Cloud computing hosted services encompasses any subscription-based or pay-per-use service that extends IT’s existing capabilities. It is a means to boost skill or add competencies on the fly without investing in new infrastructure, training new personnel, or licensing new software.
A simple example of cloud computing is Yahoo email, Gmail, or Hotmail etc.. Having an internet connection is all that you need first and you can set off by sending emails. The server and email management software is all in the internet, that is in the cloud, and is entirely dealt with by the cloud service provider Yahoo, Google etc.. This technology functions in three segments: application, storage, and connectivity. All over the world different purposes of businesses and individuals are served in each of the segments.
In a cloud computing system, there’s a considerable shift of workload. Local computers no longer have to take the load of heavy lifting at the time of running applications. This latest computing technology will handle them instead. The demands of hardware and software on the user’s side will decrease. The only thing the user’s computer needs to be able to run is the interface system. This is as simple as a Web browser, and the cloud’s network takes care of the rest.
There are three distinctive characteristics that have differentiated cloud computing from traditional hosting. Firstly, it is sold on demand by minute or hour. Secondly, it is elastic. A user can enjoy as much or as little of the services as they demanded at any given time. Thirdly, the service is fully managed by the provider. The significant enhancement in Virtualization and circulated computing, as well as improved access to high-speed internet, has accelerated interest in cloud computing.
The cloud computing services can be public or private. A public cloud sells services to anyone on the internet. A private cloud is a proprietary network. It is also a data center that provides hosted services to a limited number of people. When public cloud resources are used by a service provider to create their private cloud, the result is called a virtual private cloud. Private or public, the goal of cloud computing is to provide easy admittance to computing resources and IT services. Services can be anything from Web-based email to inventory control, and database processing. Because the service provider controls both the applications and the data, the user can use the service from anywhere freely”.’
We are fast moving towards this kind of computing society. With cloud computing gets its speedy hold in the world of internet, you’ll have a very charming possibility of future prospect. You need to get all the specialized technical terminologies like off-site, third-party provider, access via internet, provisioning, system interface, shared resources or common versions etc.. With this innovation, users have access to their information through the Web. So it’s accessible from anywhere they need it.
Cloud computing is a helpful tool for businessmen who want to store and maintain databases. It’s an easy way to organize information in different departments while allowing for company-wide collaboration. Services offered by cloud computing are actual software, but it is never installed on a computer. This is what’s known as software-as-a-service, or SaaS. The software is accessed through the Internet. A big benefit that is often enjoyed by the companies who use cloud services is that they are free from fear of losing, or having unsecured data. There’s no need to save all the time in case a computer collapse. There’s no in-house server required for daily backup, either. All of the IT worries are almost vanished. Still security is maintained, because all the information is password accessible.
The phrase ‘Cloud Computing’ refers to cloud of data that hovers on the internet. These can be obtained and retrieved on any computing gadget from anywhere with the internet connection. You need not save files to your hard disk. All data is saved automatically. Speedy browsers are necessary to run a cloud application well. What’s more, the cloud also offers the storage facility of the files online. You may wonder, why we need cloud computing while our desktop or laptop can perform this kind of services. Cloud Computing is created for the tomorrow’s world for different kinds of computing services to make the functionality and data we require constantly accessible no matter where we are across the world, and no matter what computing devices we are using to have instant access to the internet.
