What is edge computing? | Opensource.com
Edge computing is poised to boost the next generation of IoT technology into the mainstream. Here’s how it works with the cloud to benefit business operations in all industries
There is much speculation about edge replacing cloud, and in some cases, it may do so. However, in many situations, the two have a symbiotic relationship.
The distributed nature of edge computing (when built right) means that along with reducing latency, it can also improves resiliency, reduces networking load, and is easier to scale.
Processing of data starts at its source, which helps to reduce latency and makes systems more realiable because networks always add latency and are never 100 per cent reliable. Once initial processing in edge computer is completed, only the data that needs further analysis or requires other services needs to be sent to cloud. This reduces networking requirements.
Over the next few years, we will see an explosion in this technology.
For example services such as AWS Lambda may be overhauled to run functions at the edge location nearest to the request’s origination point: We have already seen the first signs of this with AWS Lambda@Edge. With systems such as AWS’s Lambda@Edge, Greengrass, and Microsoft Azure IoT Edge, edge computing has become a key factor driving the adoption of technologies such as IoT.
We will also see the maturing of emerging edge technologies such as blockchain and fog computing.
As edge matures, cloud computing will grow along with it.
