How Cloud Computing Works

By Nextrio on July 15th, 2014 Facebooktwittergoogle_plusredditlinkedinmailby feather

Have you purchased computers and software licenses for every employee at your business? Do you constantly have to buy more physical servers and storage devices to accommodate your ever-growing data? Are your employees limited in their flexibility because important files are only accessible through a single computer? If so, moving your business infrastructure to the cloud may be the perfect alternative. Here’s a closer look at cloud computing and how it works.


Instead of installing an entire suite of software on each computer, cloud computing allows you to log into one web-based service that hosts all the programs and files the user needs. Remote machines owned and operated by another company handle the heavy lifting when it comes to running the programs, processing data, and storing information.

Front End and Back End Architecture

The front end and back end of the cloud computing system are connected to each other through a network, usually the Internet. The front end is what you, the user, sees. The “cloud” is the back end of the system. The front end includes your computer and the web-based application required to log into the cloud. The back end includes a system of various computers, servers, and data storage devices that make up the cloud of computing services.


A central server in the back end ensures that everything runs smoothly by monitoring user demands and traffic. This server administers the system by following set protocols and using a special kind of software called “middleware.” Networked computers on the cloud are able to communicate with one another via middleware, thereby allowing them to allocate processing power and maximize output of individual servers for optimal efficiency.

Storage and Redundancy

Like all computers, the machines that make up a cloud computing system may occasionally break down. For this reason, the cloud system needs enough digital storage to keep its users’ information, and copies of that information, stored on multiple devices for guaranteed retrieval. Making backup copies of data is called redundancy.
