Edge use cases
Edge systems are collocated as shown in the preceding figure, close to where data is generated or people are located. Currently, about 20% of data in enterprises is collected outside of corporate walls. Gartner predicts that by 2023 up to 75% of corporate and enterprise data will be collected and managed by systems outside the physical borders of enterprise IT and data centers.
Edge computing serves four primary usage patterns:
- Reduced latency: Edge systems can be placed closer to end users and services. This naturally can avoid various network hops and propagation. Certain latency-sensitive applications, such as cloud-based gaming and video streaming, have strict real-time latency and performance requirements. This also includes devices that need real-time decision-making or the execution of rules engines for safety-critical machinery.
- Bandwidth preservation: Certain environments have limited bandwidth to and/or from the edge system. In other...
