Cloud computing is a topic that many find confusing. It isn’t, though, as confusing as it sounds. In fact, most of those who claim not to understand the subject are part of the majority that uses it daily.
Cloud computing is a model for delivering information technology services in which resources are retrieved from the internet through web-based tools and applications, rather than a direct connection to a server. Data and software packages are stored in servers. However, cloud computing structure allows access to information as long as an electronic device has access to the web. This type of system allows employees to work remotely.
A simple example of cloud computing is Yahoo email, Gmail, Hotmail or Carbonite 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 most cloud computing applications, data is sent to remote processors via the Internet, the process is completed, and the resulting data is sent back. A frequent example is Carbonite online backup , where you use a software interface but the bulk of software activity is carried out remotely instead of by your own computer.If you are looking for a provider of this kind of service Carbonite offers a robust system for back up and each month sends out deals and coupon offers to save you money if you do sign up, the latest ones have up to 30% off.
The characteristic of Cloud Computing consists of self-service, where a customer can request and manage their own computing resources. An access to the broad network permits service to be available for the private networks or the Internet. This technology provides a pool of shared resources, where the customer draws from a pool of computing resources, usually in a remote data center.
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.
Organizations that implement cloud computing technologies can have a significant impact on their ability to reduce their electricity bills dramatically. If you ever seen your company’s data center, you could see up to hundreds or more servers depending on size of your company’s business. Each of these servers generates heat and if they generate to much heat then the servers stop working. When servers stop working then mission critical applications go down and this leads to a lot of customers complaining to the help desk. Data centers have built in cooling systems to help keep the room cool and at certain humidity. All of this cost the company a lot of money to keep the servers running at optimal performance. Now, if each organization has a data center and each has their own cooling system this is leading to a lot of electricity that is being used to keep all of these data centers running around the world. Cloud computing helps save the environment because it is shared infrastructure resources that a vendor provides to an organization. Cloud computing vendors that specialize in infrastructure service have built up data centers around the country and offer their data centers to other companies. Companies do not need to have their own data centers, they can just have their applications hosted with the cloud computing provider to help save energy through sharing resources.
In a cloud computing system, there’s a significant workload shift. Local computers no longer have to do all the heavy lifting when it comes to running applications. The network of computers that make up the cloud handles them instead. Hardware and software demands on the user’s side decrease. The only thing the user’s computer needs to be able to run is the cloud computing system’s interface software, which can be as simple as a Web browser, and the cloud’s network takes care of the rest.
