Caching and Throttling
Implement caching to reduce latency and manage traffic spikes with throttling and usage plans in API Gateway.
Boost API Performance
In the world of APIs, speed and reliability are key. High latency (slow responses) frustrates users, while sudden traffic spikes can crash your backend services.
This lesson explores two powerful features in AWS API Gateway: caching and throttling. They help you deliver fast, stable, and cost-effective APIs.
What is API Caching?
Caching is like having a temporary storage for frequently requested data. Instead of always fetching data from your backend (e.g., a database or Lambda function), API Gateway can store the response and serve it directly.
- Reduces latency: Responses are returned much faster.
- Lowers load: Your backend services receive fewer requests.
- Saves costs: Less compute/database usage.
