- Describe the similarities between AWS API Gateway + Lambda functions and an ExpressJS Server.
Amazon API Gateway and Express Gateway both have their strengths and weaknesses. Amazon API Gateway has a compelling case for massively scalable API gateways at a competitive price point. With Express Gateway, you are responsible for hosting and running your own API Gateway, which may be more or less expensive depending on your experience and the load on your API Gateway. In particular, you may need to manage the number of Express Gateway servers you’re running and configure a load balancer in front of your gateway servers if your API has sufficient load, which may be cumbersome and expensive.
