Rate limiting, maximum concurrent connections, retries, and circuit breakers are all techniques used to manage the flow of traffic to a server or service and improve its stability and performance. Some key benefits of these techniques include: Protection against malicious traffic: you can use Rate limiting, maximum concurrent connections, and circuit breakers to protect against denial of service attacks and other forms of malicious traffic. These solutions limit the rate at which requests are accepted and impose limits on the number of open connections or failed requests. Improved system reliability: By limiting the processing rate of requests and implementing retries and circuit breakers, it's possible to mitigate the impact of temporary issues such as server overloads, and ensure that the system remains available and responsive to clients (improved user experience). This can help to ensure that the system remains secure and able to withstand attacks. Efficient resource usage: By limiting the rate at which requests are processed and the number of concurrent connections,
