How Does Edge Computing Work?

Edge Computing is an increasingly popular approach to delivering computing solutions that are both efficient and cost effective, while also freeing up infrastructure. Edge computing is also an evolution of the networked data centre.

An edge computing system consists of a central data repository that is used to store information for processing. The information is then distributed over a number of nodes to enable fast retrieval or execution of business processes. The central repository is accessed by users as required to make use of its compute resources. Edge computing architecture involves many different types of computers and devices to allow users to make use of the power and flexibility provided by a single hardware device, allowing access to the information required at any point of time.

In distributed systems, computing resources are not limited to a specific physical location. As the name suggests, nodes are interconnected through the use of a network, and the nodes communicate with each other via a router, usually controlled by the network service provider. The routers and the nodes are connected to each other through a large number of cables and optical fibers. The communication links in these networks allow the users to have direct access to all their computers and therefore are known as edge devices.

In the conventional computer, data is stored either on a traditional hard drive or in a virtualised server. The data is then accessible either through a network or by physically accessing the device in question. The former has many advantages, one of which is that it allows the user to access all their data from any place, anywhere. However, this can be problematic because users cannot access the same data from more than one machine simultaneously and thus face bottlenecks. Virtual servers provide an edge computing solution to these problems by allowing multiple users to access the same data in real-time from different locations.

Another advantage of this method is that they provide a secure environment for all network data. They work by creating two layers of protection: firstly the partitioning of the network between users, and secondly the use of IP addresses, routing tables, and tunnels to ensure that users can only access the data on their local network. This ensures that users can access the information they need to effectively and at the same time without affecting other users in any way. It also prevents the users from sharing sensitive data between them. The use of VPN technology and security software such as LSM or LMS can also be used to further enhance network security, especially when dealing with sensitive information.

Edge computing architecture has brought new levels of efficiency to the IT industry. It has given companies an opportunity to improve their overall operational performance and productivity. With the growing popularity of cloud computing services such as Microsoft Office 365, Amazon Web Services, and Rackspace, businesses can focus on providing great services rather than focusing on managing and storing information.
