What is Edge Computing?


The term Edge computing is doing the rounds nowadays! Let’s explore what is Edge Computing here!
Edge Computing is a networking philosophy that concentrates on bringing computing as close to the source of data as possible. This reduces latency and bandwidth use. With edge computing you are running fewer processes in the cloud and moving those processes to local places like a user’s computer, an IoT device, or an edge server. By doing so you can minimize the amount of long-distance communication that has to happen between a client and server.

Cedar Software Technologies, a prime web development company in Kochi, leads you through an insight on Edge Computing.

What is the network edge?


The term is rather fuzzy! The network edge is where the device, or the local network containing the device, communicates with the Internet. A user’s computer or the processor inside of an IoT camera can be considered the network edge. The user’s router, ISP or local edge server are also considered the edge. The edge of the network is geographically close to the device in comparison to origin servers and cloud servers.

What’s an example of edge computing?


Consider dozens of high-definition IoT video cameras in a building which continuously stream signals to a cloud server. Processing these signals causes a constant and significant strain on the building’s Internet infrastructure & cloud server exhausting significant bandwidth. 

If this motion sensor computation is moved to the network edge like each camera using its own internal computer to process signals and then sends footage to the cloud server as needed. This would result in significant bandwidth use reduction & the cloud server would now only have to store the important footage without getting overloaded. This is what edge computing looks like!

What are the benefits of edge computing?


  • Edge computing helps minimize bandwidth use and server resources. which are finite and cost money. It is said by 2025 there will be over 75 billion IoT devices installed worldwide. To support all those devices, vast amounts of computation will have to be moved to the edge.
  • Edge computing reduces latency. A delay occurs every time a device needs to communicate with a distant server somewhere. If that process is brought to the edge, noticeable delay would not exist.
  • When web applications run into processes that have to communicate with an external server, there will be delays. These can be avoided altogether by bringing more processes to the network edge.
  • Edge computing can also provide new functionality like the ability to process and analyze their data at the edge, which makes it possible to do so in real time.

What are the drawbacks of edge computing?


  • Edge computing causes more ‘smart’ devices like edge servers and IoT devices to work together which can attract malicious attacks to compromise these devices.
  • Edge computing requires more local hardware with more processing power.
  • Edge servers can be used in place of costly local hardware.
