One of the newest buzz words in IT these days is cloud computing. You may not work directly with it but most likely sooner than later you will be using it whether you know it or not so it wouldn’t hurt to know just a little about what it is and how it works.
To try to make it easy I will explain it in 2 different ways. How it compares to old telephone technology and the other is the actual design as it relates to modern networks and computers.
When I first started hearing people talk about cloud computing I said that sure sounds like an old frame relay circuit, or something a little more familiar a party line, where several people are using the same resource to save money. You could use it when you wanted to as long as your neighbor wasn’t on it. In cloud computing it is kind of the same. Computer users will all user the same piece of software from a remote location saving space on their computers and allowing for more consistency as it is centrally managed therefore all the same. Unlike party lines you don’t have to wait for your neighbor to get off to use it. Networks are much more effective than they were back then. They break everything up into little pieces and send it. That way it uses all of the available space if it is needed. So when a new user joins the team they are added to the user group on the network and they have access to everything that is assigned to that group.
Now the techie version.Cloud computing works on the Application layer whereas Frame Relay was on the network layer of the Network stack. In cloud computing software is loaded on a server somewhere that is connected to the internet. The users may be internal to a company or may be a collection of small companies that access a managed service that allows them to save time and money.
Keep in mind that this is just the most basic description to help you get out of the dark and know what people are talking about.
