Deploy

In order to deploy the endpoint you simply run

npx serverless deploy --stage=stage_name --aws-profile=profile_name

The expected result should be similar to:

Serverless: Packaging service...
Serverless: Uploading CloudFormation file to S3...
Serverless: Uploading service .zip file to S3 (758 B)...
Serverless: Updating Stack...
Serverless: Checking Stack update progress...
..........
Serverless: Stack update finished...

Usage

You can now invoke the Lambda directly and even see the resulting log via

serverless invoke --function currentTime --log

The expected result should be similar to:

{
    "body": "{\"message\": \"Hello, the current time is 15:40:19.009371\"}",
    "statusCode": 200
}

Finally you can send an HTTP request directly to the endpoint using a tool like curl

curl https://XXXXXXX.execute-api.us-east-1.amazonaws.com/dev/ping

The expected result should be similar to:

{"message": "Hello, the current time is 15:38:53.668501"}%  

Scaling

By default, AWS Lambda limits the total concurrent executions across all functions within a given region to 100. 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.
