 How cloud computing works?

To understand how our stuff is stored on the “cloud”, we have to know how cloud computing works? The cloud computing architecture comprises of two parts: the frontend and the backend which are connected by the internet. The frontend represents the computer that the client sees. This side requires that the users can access the cloud computing system. Gaining access can be as simple as use an internet browser or can be more complex, by using unique interface software which helps users access the cloud.

The backend of a cloud computing system is comprised of the computers, servers and the data storage systems, which store all your files and information. This is actually the part that does all the “work”! There is a central server that administers the system, monitoring traffic the client demands to ensure everything runs smoothly. In addition, this central server follows a set of rules known as protocols. The central server also uses software called middleware that allows the network computers to communicate with each other.


Naturally, cloud computing companies build in redundancy where they save multiple backup copies of your work in case of problems. However, the more clients they have the more storage space they need. So cloud computing companies require at least twice the number of storage devices to store all their clients’ information.


So, it is obvious that for any company, small or big, moving to cloud computing for their storage needs is beneficial. But when weighing the options, the first question that comes to one’s mind is the safety of data stored on the cloud. It is true that cloud computing companies provide adequate security, but you also need to protect yourself. And how is this possible? Have authentication techniques like usernames and difficult passwords. Don’t reuse or share your passwords on different websites and backup files either on a different cloud service or hard drive just in case something happens. There are also authorization practices where you list certain people who are authorized to access certain information stored in the cloud system. For example, an employee may only be able to use certain stored on the cloud, which are pertinent to his work.
