Edge computing refers to the practice of processing data closer to the source or user, rather than relying solely on centralized cloud data centers. This approach enhances performance by reducing latency and improving reliability. AWS provides a range of services that facilitate edge computing, allowing businesses to deploy applications and manage data processing at or near the physical location of their users or data sources.

AWS employs a multi-layered security strategy for edge computing, which includes preventive measures like encryption and access control, continuous monitoring through configuration auditing, and physical security features. AWS services are designed to meet stringent security requirements, ensuring that data is encrypted during transit and at rest, and providing tools for monitoring and managing security across edge devices and applications.

DDoS mitigation involves strategies and technologies aimed at protecting against Distributed Denial of Service attacks, which can disrupt the availability of services by overwhelming resources. For organizations operating at the edge, effective DDoS mitigation is crucial to ensure continuous service availability and operational integrity. AWS offers services like AWS Shield to help protect against various types of DDoS attacks, ensuring that mission-critical operations remain functional.
