​​Lambda Function URL: 🎉

https://aws.amazon.com/blogs/aws/announcing-aws-lambda-function-urls-built-in-https-endpoints-for-single-function-microservices/

Each function URL is globally unique and can be associated with a function’s alias or the function’s unqualified ARN, which implicitly invokes the $LATEST version.

For example, if you map a function URL to your $LATEST version, each code update will be available immediately via the function URL.

Lambda Function URL vs. API Gateway

Function URLs are best for use cases where you must implement a single-function microservice with a public endpoint that doesn’t require the advanced functionality of API Gateway, such as request validation, throttling, custom authorizers, custom domain names, usage plans, or caching.

Pricing

Function URLs are included in Lambda’s request and duration pricing. (So it's FREE!💪)

▪️ Rest API (first 333 mil) = $3.5
▪️ HTTP API (first 300 mil) = $1.0
▫️ Lambda URL = Free
▪️ CloudFront proxying to Lambda URL = ~ $1.0 to $1.2

Timeout (seconds)

▪️ Rest API = 29
▪️ HTTP API = 30
▫️ Lambda URL = 900
▪️ CloudFront proxying to Lambda URL = 60 (by default)
