AWS Lambda λ  - Computing

• https://aws.amazon.com/lambda/features/  & https://en.wikipedia.org/wiki/AWS_Lambda
• Serverless service that runs your code in response to events and automatically manages the underlying compute resources for
• This is an event capturing service. If a function is created and assigned to DB each event in the DB invokes this λfunction service
• Server less compute which an be used to address a use case quickly. Later on when it can be moved to EC2 when needed
• There cab be synch and asynch λfunction
• No allocation of CPU and only allocate Memory(128M to 3GB) for λ functions
• λ function should finish within a maximum of 15 minutes
• charged on how much time a λ function takes to execute
• Steps

1. Go to IAM and create a role of type AWS Service and select λ and click next button
2. Select the AWSLambdaBasicExecutionRole from the policy list which provide write access to CloudWatch Log
3. Provide the name as "LambdaBasicExecutionRole" in the last step and click on create 
4. Go to Lambda console and click on create function button to create a lambda function which provide the following options and select the first one
1. Author from Scratch
2. Use blue print
3. Deploy from AWS Serverless Repository 
5. Provide the following details
1. Function Name: HelloName
2. Runtime: Any runtime like nodejs, java etc.
3. Role:  Role created above
6. Give the following details to the above  λ function
1. code entry type: Edit code inline
2. Runtime: Node.js
3. handler: index.handler (Need to create a file named index.js and put a function named handler in that file)
7. In the code pane create a new file named index.js  with the following details
1. exports.handler = async(event) => {
2.     console.log("event:" +JSON.stringify(event));
3.     const response = {
4.         statusCode : 200,
5.         body : JSON.stringify("Hello from Lambda λ " + event.name)
6.     };
7.     return response;
8. };
8. Now click on Test and create the json as {name: MyName} and execute you can see that the λ function got executed
9. Now need to create an API using API Gateway
10. Create a new REST API with the following settings
1. Protocol : REST
2. New API
3. API Name: HelloName
4. EndPoint type: Regional (Regional, Edge Optimised, Private)
11. Click on Actions dropdown menu and click Create Method
12. Select GET as the method type on default(/)
13. Select newly created GET method to define its properties as given below
1. Integration type: λ function(other values can be HTTP, Mock, AWS Service, VPC Link)
2. Use λ proxied integration selected. That will make sure to take the input request and patches them and send that to the λ function event
3. λ Function: The previous one created and click on save button
14. The API got created. Click on Method Request and add a query parameter as "name"
15. Now need to change the λ function to make the following change
1. body : JSON.stringify("Hello from Lambda λ " + event.name) changed to body : JSON.stringify("Hello from Lambda λ " + event.queryStringParameters.name)
16. Now the API Gateway is ready to test
17. To Deploy the API click on Actions(Dropdown menu) -> Deploy API . After deployment you will be getting a url that will be available to invoke the API
