AWS Shield
AWS Shield is a managed Distributed Denial of Service (DDoS) protection service that safeguards applications running on Amazon Web Services. It provides always-on detection and automatic inline mitigations to minimize application downtime and latency. AWS Shield offers two tiers: Standard (free for all AWS customers) and Advanced (paid with enhanced features).
Developers should use AWS Shield to protect web applications, APIs, and other services from DDoS attacks that can disrupt availability and incur high costs. It is essential for businesses requiring high uptime, such as e-commerce sites, gaming platforms, or financial services, especially when using AWS Shield Advanced for detailed attack diagnostics and 24/7 access to the AWS DDoS Response Team.
