OK, lets move to the matter… cloud computing has nothing to do with angels and paradise, except that, they will probably use it soon, too. Yes, this appears to be the next hot sector of the IT industry in the world. Everything has been moving to the ‘cloud’ for the last several years and this is why extremely important for everyone to know its basics.

Cloud Computing Explained…

Okay, “cloud” means a server located anywhere on the globe, maintained by a team of good professionals, and giving you the chance to use it from your own computer (no matter it’s desktop, mobile or anything else). It’s accessible through the Internet from everywhere, from any device, it’s fast, it’s reliable and the most important – It’s CHEAP.¬†Cloud computing has put a new age in software industry called Saas, or Software As A Service. Moving just the hardware on a remote server is just half of the game. Moving the software working on the ‘cloud hardware’ is what actually Saas is. So, using the cloud simply means using remote hardware and software through the Internet.. Usually you don’t buy the remote hardware and software, but you pay for them on a monthly basis, just like you are renting them.

Pros and Cons of Cloud computing (Advantages and Disadvantages)

Pros

1. It’s cheap – a license for a software may cost really much and it may be really expensive to buy it. If you use it in the cloud, you actually pay a monthly rent for it which is substantially cheaper option in the short run. Also, you don’t need to pay for people to administer your server or maintain your software. it’s all included in the rent and you get high skilled professionals doing that. You don’t but hardware, too. Cloud computing lets you start using cutting edge software and hardware with extremely low starting budget, but in some cases it may be the more expensive option (see the cons).
2. You pay for what you use – cloud services can easily be expanded or collapsed. If you need another license of a software, you can just pay the additional rent for it. You don’t have to buy it and pay it’s full price. If you need to reduce your licenses, you just stop renting them and pay for just what you use.
3. It’s accessible – you can use your ‘cloud’ from everywhere with available Internet connection. You can use it usually from any device and operating system.
4. It’s secure – the administrator of the cloud services are highly skilled and professionally focused guys and gals. If you want to achieve such a security for your in home/in office server, you need to pay big time for good employees and other devices such as UPSes to achieve it. all of this is included in the rent of a cloud service and it’s much more affordable.
5. You are always up to date – cloud services usually use the latest version of software and hardware components to stay competitive. If you have to this in your office, it will be much more expensive.
