Create a server-less API that says “Hello Serverless” or “Hello , <YOUR-NAME>” and Host it for $0 for up to a million hits. Though this example doesn’t compute anything ,if you have a memory efficient algorithm in place and have a valuable dataset and your resultant payload from a Lambda execution is minimal, you can run the initial days of your startup for free !!!
- AWS Cloud
- AWS API Gateway
- AWS Lambda
Prep Time :
~ 15 minutes
What we will build :
But a tweak is that you will be actually hosting the service to the world in under 15 minutes.
Visual Flow :
Logical Flow :
– Creating Lambda Function
- Create a Lambda function in Java that takes in a NAME(String)and renders ****back with the following format.
