Simple HTTP Endpoint Example
Inspired by the aws-node-simple-http-endpoint, in Ruby!
Use Cases
- Wrapping an existing internal or external endpoint/service
Deploy
In order to deploy the endpoint, simply run:
sls deploy
The expected result should be similar to:
Serverless: Packaging service...
Serverless: Excluding development dependencies...
Serverless: Uploading CloudFormation file to S3...
Serverless: Uploading artifacts...
Serverless: Uploading service .zip file to S3 (849 B)...
Serverless: Validating template...
Serverless: Updating Stack...
Serverless: Checking Stack update progress...
...............................
Serverless: Stack update finished...
Service Information

api keys:
None
endpoints:
GET - https://spmfbzc6ja.execute-api.us-east-1.amazonaws.com/time
functions:

Scaling
By default, AWS Lambda limits the total concurrent executions across all functions within a given region to 1000. The default limit is a safety limit that protects you from costs due to potential runaway or recursive functions during initial development and testing. To increase this limit above the default, follow the steps in To request a limit increase for concurrent executions.
