How does edge computing relate to cloud computing?

Edge computing and cloud computing are related but distinct concepts that can complement each other. The main difference between them is how and where data processing takes place 12.

• Cloud computing is a style of computing that delivers scalable and elastic IT-enabled capabilities as a service using internet technologies 3. Cloud computing involves running workloads on centralized servers or data centers that can be accessed remotely via the internet. Cloud computing offers benefits such as lower upfront cost, flexible pricing, limitless compute on demand, simplified IT management, easy updates and reliability 4.

• Edge computing is a distributed computing paradigm that brings computation and data storage closer to the sources of data 5. Edge computing involves running workloads on edge devices or servers that are located near the devices or systems that generate or consume data. Edge computing offers benefits such as improved speed/reduced latency, enhanced security/privacy, increased scalability, greater versatility and higher reliability 1.

Edge computing and cloud computing can work together to provide optimal solutions for different use cases and scenarios. For example:

• Some applications may require both edge and cloud processing for different tasks or stages. For instance, an edge device may perform initial filtering or analysis of data locally, then send aggregated or relevant data to the cloud for further processing or storage 1.

• Some applications may use edge processing as a backup or failover mechanism in case of network failures or disasters that affect cloud connectivity or availability. For example, an edge device may store critical data locally until it can be synced with the cloud when network conditions improve 1.

• Some applications may use edge processing to complement cloud processing by providing additional features or capabilities. For example, an edge device may provide local caching or content delivery for faster access to frequently used data or resources from the cloud 1.
