In conclusion, API throttling is a crucial mechanism for maintaining the performance and availability of APIs. By implementing the top 11 techniques discussed, including rate limiting, concurrency control, quotas, and caching, organizations can effectively manage and control the flow of API requests. It is important to carefully consider the specific requirements and constraints of each API use case to determine the most suitable throttling strategy. With proper implementation of these techniques, organizations can optimize their API performance, prevent abuse, and ensure a seamless experience for users while protecting the backend infrastructure from overload.
