Edge computing refers to a concept in which the data processing and analysis is closer to the data sources. This improves response time and also save bandwidth. This idea is gaining momentum due to the networking of more and more devices generating huge volume of data. Data handling and analysis becomes crucial here.
According to Gartner Edge computing is projected to expand to  6.7 billion in 2024, with an estimated CAGR of 15.3 %. Edge Computing technology is particularly appealing for companies with data that is generated from remote places like IoT devices, mobile devices, IoT devices, and sensors. Top cloud consulting companies take utmost care in ensuring that data processing is close to the source which reduces the requirement to pay for expensive and long-running data transfer over distances.

In addition, edge computing reduces the costs of cloud computing because it permits organizations to transfer only certain data across long distances to store as well as analyze on the cloud. It is a kind of Internet of Things (IoT) technology that allows computation to be carried out within the nodes of an IoT system. These nodes include fog gateways and nodes. 

 

The Growing popularity of Edge Computing

 

  • Edge computing is gaining popularity because of its ability to circumvent the limitations of traditional cloud computing. It includes poor access to connectivity as well as high latency. This is particularly beneficial in areas like manufacturing, retail and healthcare where fast analysis of data is essential to make the right decisions.
  • Edge Computing has evolved from other models of cloud-based services like Fog Computing and Cloudlets. Contrary to Fog Computing, which focuses on processing data between edges and the cloud, edge computing concentrates solely on data that needs to be processed at the edge. Cloudlets focuses on providing on-premise computing services for mobile applications. In contrast, Edge Computing is more focused on delivering an open computing platform that can be used to support IoT applications.

Edge Computing 101

 

Edge computing refers to a type of cloud computing that allows data, computation applications, storage, and data to be placed at the far end of the network, where they can be easily accessed by users. It’s an abstract idea that allows devices like smartphones, tablets, or laptops to process data locally, rather than sending data to the internet to be processed in the cloud. This reduces the latency of communication, increases response times, and reduces the cost of data transfers. Edge computing is the ideal solution for those applications that require instantaneous data analysis like the ones in manufacturing, retail as well and health care.

Edge computing companies can enable it through different components including gateways, edge servers, and IoT devices.

  • Edge servers are devices that are situated near the data source which can save and manage information locally. Gateways serve as a bridge between local networks and cloud services, allowing safe access to the data within the cloud.
  • Additionally, IoT devices provide connectivity to a variety of devices on the edge, which allows devices to connect with their counterparts and with the cloud.

The use of edge computing can be utilized for many applications, including the use of predictive maintenance and real-time analysis, automated decision-making, and many further.
