DDoS Protection
DDoS protection defends services against distributed denial of service attacks, in which many compromised machines flood a target with traffic to make it unavailable. Protection systems detect and drop attack traffic while allowing legitimate requests through.
Technical Architecture & Deep-Dive
Attacks range from network-layer floods measured in terabits per second to application-layer floods of seemingly valid HTTP requests aimed at expensive API endpoints.
Large edge networks use anycast to spread attack traffic across hundreds of data centers and filter it close to its source. Placing APIs behind such a network, combined with rate limiting and caching, keeps origins and third-party quotas safe during attacks.
Key Architectural Benefits
Implement DDoS Protection at the Edge
Deploy lightweight API aggregation, edge caching, and secret injection in minutes without Docker containers or complex servers.
Frequently Asked Questions
Q:Can a small API be targeted by DDoS attacks?
Yes. Attacks are cheap to launch, and small services without edge protection are often easiest to overwhelm.
Related Architecture Concepts
Anycast routing is a network technique where the same IP address is announced from many data centers simultaneously. Internet routing protocols deliver each request to the topologically nearest location, so users automatically reach a nearby edge server without DNS tricks.
API Rate Limiting is a traffic control mechanism that caps the number of requests a client, IP address, or API token can execute within a specified time window. Rate limiting prevents server overloading, protects against credential brute-forcing, and shields upstream APIs from exceeding subscription quotas.
A Web Application Firewall (WAF) is a security layer that inspects HTTP requests and blocks malicious traffic such as SQL injection, cross-site scripting, and known exploit patterns. It sits in front of web applications and APIs, filtering attacks before they reach origin servers.
