Intermediate AWS Lambda Interview Questions 1. How can we deploy dependencies alongside Lambda code? There are a few options for packaging dependencies with Lambda code: Direct inclusion: For interpreted languages, we can put dependency files along with our function code in the .zip deployment packag...
If you remember, I was pretty happy to see how the new Java 8 compiler uses the invokeDynamic instruction introduced in Java 7 to link to the Lambda function code. Well, with Nashorn they really went to the races with it. Everything now is completely based on it. Take a look belo...

Java C# Go Python The core concepts of writing the lambda code is as follows. Handler: Handler is the function which AWS Lambda calls when it is triggered by the cloud events. The first step in writing the Lambda functions is to define the Handler function. When the Lambda functions are ...
The workaround I found was to use the map function as the success case and the orElseGet to return the failure case. In both branches the code returns an instance of ThrowingRunnable by having a lambda return a lambda. Therun()is then called at the end and it can throw any exception...

Create a new Lambda function in the AWS Management Console. Choose Node.js as the runtime environment. Write your API logic in the function. For example, a simple “Hello World” endpoint: 1 2 3 4 5 6 exports.handler =async(event) => { ...
