Introduction to Edge Computing
As digital systems generate massive volumes of data, traditional cloud-centric models are struggling to keep up. Edge computing has emerged as a practical solution, bringing data processing closer to where information is created. Instead of sending everything to distant data centers, edge computing enables faster decisions, reduced costs, and improved reliability.
What Is Edge Computing?
Edge computing is a distributed computing paradigm where data is processed near its source, such as sensors, devices, or local servers. This minimizes dependence on centralized cloud infrastructure.
Key Characteristics of Edge Computing
-
Low latency due to local data processing
-
Reduced bandwidth usage
-
Improved system resilience
-
Enhanced data privacy and control
