The serverless framework is very popular for the last 5 years. AWS Lambda is the most important service in the Serverless framework.

AWS Lambda supports Ruby runtime on November 29, 2018. Now we can develop AWS lambda with Ruby. But what situation should we use AWS Lambda?

The key point in this talk is "Why we choose AWS Lambda as a solution on a large-scale system?".

The first question is "What are pain points when we want to implement a new feature on a large-scale system?".

And then let's think about "How AWS Lambda solve these pain points?".

I will share some experiences about developing features with AWS Lambda. Discussing what situation should we use AWS Lambda.

Here’s what you will learn:
- What is AWS Lambda?
- What is the serverless framework?
- What is event-driven programming?
- What are pain points when we develop features on large-scale system?
- How AWS Lambda solves these pain points?
- How to develop AWS Lambda with ruby?
