Cloud computing has become mainstream due to its benefits of improved agility, scalability, and cost savings for enterprise organizations. However, with growing demands for time-sensitive and mission-critical applications, businesses are shifting to edge computing, which delivers faster response times by processing data closer to the user or device. Edge computing is distinct from cloud computing in that it stores, processes, and analyzes data at a physical location outside of a central data center, reducing latency and improving performance. The two main reasons for moving workloads to the edge are time sensitivity and workload capabilities, which are now possible on devices with smaller footprints than large cloud servers. Edge computing and cloud computing are not mutually exclusive and can be combined to serve different purposes, with function as a service playing a critical role in enabling computation across heterogeneous resources.
