AWS made a change behind the scenes to keep lambdas warm for between 45–60 minutes of inactivity as referenced here: How long does AWS Lambda keep your idle functions around before a cold start. AWS Lambda is a compute service that runs your code in response to events and automatically manages the compute resources for you, making it easy to build applications that respond quickly to new information. AWS Lambda limits are thus something you need to keep in mind when combining different Lambda Layers of various sizes. Lambda layers contain packaged code that you can import across several functions. So there is no need to make 10 lambda. It natively supports a large number of programming languages including Python, JS, Go and many others, but not PHP. It has become part of many modern applications and data. For example, you can use AWS Lambda to build mobile back-ends that retrieve and transform data from Amazon DynamoDB, handlers that compress or transform objects as they are uploaded to Amazon S3, auditing and reporting of API calls made to any Amazon Web Service, and server-less processing of streaming data using Amazon Kinesis. Those triggers could be HTTP calls; events from other AWS services like S3, Kinesis, or SNS; or just recurrent scheduled events. You can still use async/await if you’re running AWS Lambda on Node. Returns information about a version of an AWS Lambda layer, with a link to download the layer archive that’s valid for 10 minutes. zip files have the same names as in this file.
