Edge computing is a framework of computing that is done closer to the source of the data (such as local edge service or internet of things devices.) Proximity of applications to the source of the data can offer faster insights, better bandwidth availability, and improved response times. Latency is reduced because the data does not have to travel to a cloud or a data center to be processed. Edge computing enables more comprehensive and faster data analysis, which creates an opportunity for deeper insights and an overall improved customer experience.
SASE - Secure Access Server Edge - is a framework in which security and networking functions work together at the cloud edge to maximize both protection and performance.
