Introduction
As businesses and organizations increasingly rely on digital infrastructure, the debate between edge computing and cloud computing has gained prominence. While cloud computing offers centralized data storage and processing power, edge computing brings computational resources closer to the data source. This article explores the differences, benefits, and use cases of both technologies.
Understanding Cloud Computing and Edge Computing
What is Cloud Computing?
Cloud computing provides on-demand computing services, including storage, processing power, and software, over the internet. It eliminates the need for local infrastructure and enables businesses to scale resources dynamically.
