In traditional enterprise API development and backend microservice engineering, payload validation is typically focused on authorization tokens, input sanitization, and rate limits. When a backend service queries a third-party database, fetches an external web resource, or calls a SaaS API, developers often assume incoming responses are well-behaved. While standard HTTP servers implement basic timeout rules, […]
In traditional web application architecture, API rate limiting is a solved perimeter-defense problem. Using fixed or sliding windows tracked via IP addresses, user accounts, or API keys, API gateways protect backend microservices from traffic spikes, scraping scripts, and basic denial-of-service (DoS) floods. When a client exceeds their maximum throughput threshold, the gateway responds with an […]
