This document discusses serverless architecture and AWS Lambda. It provides an introduction to serverless computing on AWS, demonstrates AWS Lambda using the AWS console and a serverless YAML file, and includes a Q&A section. Key benefits of serverless include automatic scaling, pay per use pricing, and not needing to manage servers. Challenges include potential performance issues and difficulty debugging functions.

6. Q&A

4.  Serverless architecture, also known as
function as a service (FaaS), is lately one of
the hottest trends in cloud computing.

5.  Timeline:

6.  When deylod to production poses several challenges:
◦ What is right configuration (RAM/CPU/Disk) for my
workload?
◦ What is the right budget?
◦ When is the time to scale out my workload?
◦ Are we utilising our server capacity?
◦ What is the right OS to run on?
◦ Is my OS patched correctly?
◦ How to handle server upgrades?
◦ Application upgrades?

7.  Compare Client-server và serverless
 Advantage is that serverless
◦ Pricing
◦ Event-driven
◦ Auto-scaling
◦ Environments: You no longer need to set up dev, staging, and
production machines
◦ Simple code & deploy
 The downside is that serverless
◦ Performance
◦ debug
◦ The downside is that Serverless functions are accessed only
as private APIs

8. Compare Client-server vs Serverless

10.  Serverless Frameworks Includes:
◦ Node Lambda (Javascript)
