When we hear about cloud computing, the cloud it’s referring to is the internet. It’s the sharing of resource, information or even software to some extent. The average internet speed has been growing steadily and so have the devices which in turn opened up a variety of application for the cloud.
Cloud computing works by allowing client devices to access data over the internet, from remote servers, databases and computers.
The backbone that the cloud computing relies upon is the internet. The major infrastructure can then be divided into the frontend and the backend. As a user, the frontend is the end that we’re most familiar with. Front-end manages to provide users with an access to the data that is being stored in the cloud using an internet browser or a cloud computing software.
Front end is more graphical as it contains the medium itself that mostly has an attractive user interface (UI). The content that we’ve stored or is being provided is itself a front-end element.
Secondly, backend is the responsible layer for securely storing the data and providing results when requested for. The backend consists of servers, databases and computers following different architectures connecting seamlessly. Mostly there are central servers that act as the central backbone when dealing with requests.
If there’s no backend, the front end gets no access to the content and is mostly useless. Conversely if there’s no frontend, there’s no medium between the user and the raw data. Also, there are certain software that act as a middleware that ensure proper connectivity between devices linked via the cloud.
Cloud computing in essence is a way of extending an organizations capacity in terms of storage and computing by way of subscription to these cloud providers or service of similar nature.
Top Cloud Computing providers:
Cloud computing does need protective measures since it works off of the internet. Security of the data stored and the connection between the user and the server is to be ensured. Else, hackers can gain unauthorized access to the data.
Cloud service providers on their end make backups of the data on multiple servers in case of data loss, breach or server malfunction to minimize the down time. With advantages such as flexibility and the cost, software as a service is on a growing trend. Microsoft Office has now been offered on the cloud.
There are three main service models of cloud computing – Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS).
