Study Notes
Edge Computing Architecture
- Edge computing makes the cloud truly distributed and brings computation closer to the devices or sources of data
- It reduces latency by avoiding round-trips and ensures data sovereignty by keeping data where it belongs
- Edge computing allows local storage, compute, and network services, making it a distributed cloud
Three-Tier Architecture
- Edge computing follows a three-tier architecture: Data Source, Intelligence, and Actionable Insight
- This architecture is different from the traditional three-tier architecture, with no app server, database, or front-end
Data Source Tier
- The first tier is the Data Source, which is the original endpoint where data is acquired or originates
- In industrial IoT environments, this could be a set of devices generating data
Intelligence Tier
- The Intelligence Tier is responsible for running machine learning models
- This tier cuts across the cloud and the edge, with training happening on the cloud and inferencing on the edge
Actionable Insight Tier
- The Actionable Insight Tier is responsible for sending alerts to stakeholders, populating dashboards, and performing actions based on insights
- This tier takes place on the edge, with no physical boundary constraints
