AWS Lambda's main resources are Lambda functions, which contain a granular piece of code that performs a specific task. Functions can initiate using multiple mechanisms, such as the AWS SDK, HTTP endpoints or configurable events from other AWS services. This delivers flexibility to make functions ...
A convenient way to run a Lambda function in the cloud is with a test event in the AWS Management Console. A test event is a JSON input to your function. If your function does not require input, the event can be an empty JSON document ({}). The console provides sample events for a...
you can run almost any binary inside it. In this tutorial, you’ll learn how to create a flexible and scalable document conversion service using Pandoc, deployed to AWS Lambda. You’ll also learn how to deploy third-party binaries with your Lambda function, to install similar tools yourself....
Functions using Manual mode don't receive runtime updates. Lambda publishes new runtime versions in a gradual, rolling fashion across AWS Regions. If your functions are set to Auto or Function update modes, it's possible that functions deployed at the same time to different Regions, or at ...

AWS Lambda allows us to create lightweight applications that can be deployed and scaled easily. Though we can use frameworks likeSpring Cloud Function, for performance reasons, we usually use as little framework code as possible. Sometimes we need to access a relational database from a Lambda. ...
How do I invoke a Lambda from another Lambda in AWS?Jon Gallagher
You’ll learn how to: Navigate the AWS console to create a Lambda layer Implement and test a custom virus scanning tool outside of Python’s default run-time Use your Lambda layer to scan objects that get placed into an S3 bucket
The code we run on AWS Lambda is like a formula in a spreadsheet called Lambda functions. Once your function is ready, you can trigger it anytime. Lambda functions are stateless functions that have to be dependent on infrastructure. Some of the key features of AWS Lambda that you should ...
Why would I want to run CloudHSM workloads on Lambda? Below are some specific use cases enabled by this solution: When a file is added to an Amazon S3 bucket, you can trigger a Lambda function to encrypt or decrypt the file using keys stored in CloudHSM. When a file is added to an...
