Network Traffic Considerations
Edge computing reduces network traffic. It processes data locally and only sends necessary information.
Security and Privacy Considerations
Both cloud and edge computing have unique security and privacy concerns. Edge computing might reduce the attack surface by minimizing data transmission.
Attack Surface Comparison
Edge computing could have a smaller attack surface than cloud computing. This is because data is processed locally, not transmitted over the network.
Data Sovereignty Issues
Edge computing helps with data sovereignty by keeping sensitive data in a specific region.
In conclusion, knowing the differences between cloud and edge computing is vital. Businesses should consider processing location, latency, bandwidth, and security. This helps make informed decisions about their computing infrastructure.
