Cloud Computing

Cloud Computing is wonkily defined in such a way that you would assume your data’s or perhaps servers are virtually stored in the real clouds, up in the sky.

It’s actually simple if you already have a basic knowledge of how the internet works, a cloud consists of various data centers, data centers are dedicated space within a building where computer system and their associated components are housed. You can’t physically access these computers, but you can access the servers virtually with an internet connection.

You see the word “Virtually” – Virtual computing makes one physical computer act and performs like many computers. If you need a virtual server, then the host computer would borrow you one virtually without the hassle of buying hardware.

The good thing about this is that you can always scale or perhaps downgrade the resource of a certain virtual computer, I’ll cover more about this in future guides.

Back to Cloud computing:

A cloud computing provider will maintain the server and manage the housed computers with its associated component, hardware upgrades, and free you from worrying about any sort of hardware maintenance and management aspects, unlike a dedicated server where you are just given the server to manage yourself.

The downside of a dedicated server is that you can’t automatically scale when your business is growing, e.g. higher traffic, you either add a more dedicated server and distribute the traffic between the server, which requires manual setup or you add more resources to your existing server which also has its own limit.

However, if you are using a cloud server, you can automatically scale a virtual server, say you need more ram, it is automatically added, you need more storage, it’s automatically done, freeing you from the headache of managing your servers.

This gives you a brief explanation of cloud computing, in this section, we would cover lots of stuff about cloud computing, the Operating system that is used to run the server, i.e Ubuntu, hosting your website in the cloud, control panels that can be used to manage multiple websites, email accounts, Ftp accounts, Databases, DNS records and lots more.
