Deploying REST APIs using serverless architecture with AWS Lambda can deliver advantages like pay-per-request pricing and no infrastructure management but also presents challenges such as cold starts and vendor lock-in. To optimize HTTP request routing in Lambda functions, the author implemented a custom router called LambdaMux using a radix tree for efficient matching, competing with existing solutions such as aws-lambda-go-api-proxy and LmdRouter. Benchmarks show LambdaMux offers performance improvements, particularly in high-throughput scenarios. Future enhancements may include adding middleware support and query parameter parsing.
