This document discusses building scalable web apps using microservices architecture and NodeJS inside AWS Lambda. It begins with an overview of challenges with web apps, including failures that can occur when developers are unavailable. It then defines serverless computing and microservices, and lists serverless options on AWS. It demonstrates a scalable todo web app built with microservices on AWS Lambda using the DEEP framework. The presentation concludes with Q&A and next steps.

8. What is Serverless?
Not involving a server; composed only of clients.
http://www.wordsense.eu/serverless
Serverless doesn’t mean servers are no longer
involved. It simply means that developers no
longer have to think "that much" about them.
Computing resources get used as services
without having to manage around physical
capacities or limits.

13. What is Microservices?
In computing, microservices is a software
architecture style in which complex applications are
composed of small, independent processes
communicating with each other using language-
agnostic APIs. These services are small, highly
decoupled and focus on doing a small task,
facilitating a modular approach to system-building.

18. DEEP Framework
DEEP Framework is a full-stack JavaScript
framework, core component of the Platform-as-a-
Service that abstracts web apps and web services
from specific cloud providers. This framework
enables developers build cloud-native applications
or platforms using microservices architecture in a
completely serverless approach
