Difference Between Cloud Computing and Edge Computing

Cloud computing and edge computing are modern computing paradigms used to process and store data. They differ mainly in where data processing occurs and how quickly data can be handled.

What is Cloud Computing?

Cloud computing involves processing and storing data on remote servers (data centers) accessed over the internet. It provides scalability and centralized management.

            Example: AWS, Google Cloud, Microsoft Azure

What is Edge Computing?

Edge computing processes data closer to the source (devices or local servers), reducing latency and bandwidth usage.

            Example: IoT devices processing data locally

Key Differences Between Cloud Computing and Edge Computing

Cloud processes data centrally, edge processes data locally
Cloud has higher latency, edge has lower latency
Cloud depends on internet, edge can work with limited connectivity
Cloud is scalable, edge is faster for real-time processing
Edge reduces bandwidth usage compared to cloud
