Question

I am reading AWS API gateway documentation. There is a sentence confusing me

HTTP APIs enable you to create RESTful APIs with lower latency and lower cost than REST APIs.

here is the link to the page containing this sentence

What is the difference between RESTful and REST here? Because in many places I read that it's the same

Answer 1

API Gateway offers multiple modes for using it

• HTTP
• REST
• Websockets

These are all capabilities that API gateway offers. What they are saying it that if you want to develop a REST service it is better to use the HTTP options instead of the REST one.

Most likely they will suggest to use lambdas and maybe dynamodb and go down a serverless routes, but that's not mandatory.
