Everything about Cloud Computing Services

One prominent term these days is “Cloud Computing.” It is used in relation to all kinds of web services, new options of hosting plans and so on. Much is debated whether or not cloud computing is a good choice and whether it is the future or whether it is just a fad. In the midst of all the noise, many people look up, and wonder what this means. If you are one of them, let’s go for a simple explanation.

Origin of the term ‘Cloud’

There are several versions for the origin of the term, but the most popular one is that the term came jokingly to explain where the services were running. Instead of running on a server, locked in a room of the company, they went on to say that they were running “in the clouds”.

The “cloud” within the metaphor is nothing more than a set of servers, which run the most diverse services and are connected to clients over the Internet. Because servers are hidden in some distant datacenter, and all maintenance, upgrades, and modifications are done by on-site teams, without any customer intervention, the whole system becomes quite impersonal, unlike when you take care of a real server.

The core Idea behind Cloud Computing

The core idea behind Cloud Computing is to provide services over the Internet, allowing you to access files, documents, email, run applications, and so on, from any PC connected to the web. Two good introductory examples would be Gmail and Google Docs, two services where data is stored in Google’s datacenters and you simply access information using the browser, either through the PC itself, or a smartphone or any other connected device:

Needless to say, this new service mode raises many security and privacy warnings as your data is no longer stored on your PC and becomes part of the cloud, stored and replicated across multiple servers.

On the other hand, the system is much simpler and more transparent to use, since information can be accessed from anywhere and can be shared with other people quickly, which is enough to ensure its popularization. The user does not have to worry about installing OpenOffice or MS Office, nor learning how to share files or make backups. Disadvantages, on the other hand, include the performance issue (which is conditioned by the speed of the connection) and the obvious limitation that applications are unavailable if the connection drops.

With regard to hosting, in each datacenter, we have a few hundred or thousands of servers, configured in a cluster system, which makes them behave as if it were a single supercomputer. The tasks are distributed and the data is stored in a decentralized manner, with a layer of redundancy.
