Razorpay caters to millions of API requests every day that are non-uniform in nature. As a key provider of financial infrastructure in India, it is important to ensure availability of services around the clock. Further, it is also vital to ensure seamless and robust authentication and authorization, due to the involvement of financial data. This case study focuses on how we solved the availability and authorization challenges using Edge – our API gateway. It will also include insights on how our rate limiter plugin handles more than 200K RPS workloads seamlessly with latency under sub milliseconds. Key learnings include Edge architecture, how we rate limit requests on a granular level, and ensuring authorization and authentication is not impacted.
