AWS Lambda#

Resources#

• https://en.wikipedia.org/wiki/AWS_Lambda

You pay for the execution time of your function, rounded to 100 ms.
As event source you can have (just a few examples) S3 buckets, SES, SNS, DynamoDB and API Gateway or ALB (web requests), complete list here, both synchronous and asynchronous.
Your function runs in one of the available runtimes ((versions of) languages)
The code you write does not have to be reentrant, "If the function is invoked again while a request is still being processed, another instance is provisioned, increasing the function's concurrency."

Questions / things to find out#

• configuration, how to configure your app?
• logging, where does the output of the app go?
• (blue/green) deployment
• security / context, what options are there?
• throttling options?
• monitoring (throughput and response times)
• integration with other functions and (AWS) services
• application session state options?
