- 4. Millions Thousands Hundreds Minimizing data The Aim: Low Latency High Response
- 5. Fog Cloud Location Local Internet Data Thousands Hundreds Latency and Delay Low High Storage Distributed Centralized Differences between Fog and Cloud:
- 6. • Which protocol will be used with low response time and high throughput? • Which is the best location for servers that represents the lowest delay in order to rapidly send notification to end user? • Is Fog Computing actually has better performance than Cloud Computing? Research Questions:
