1. Serverless With
Lambda, NodeJS and ClaudiaJS
AWSome Meetup on 31st of October

2. Hi, I’m Riza

3. Serverless

4. “A new cloud compu!ng trend
that changes the way you think
about wri!ng and maintaining
applica!ons.”
Tomasz Janczuk
Chief Architect for Webtasks at Auth0

5. “The essence of
the serverless trend is the
absence of the server
concept during so"ware
development.”

"For 400.000 ac!ve user we have paid $0.53 for
Lambda. Now, beat that with your hos!ng cost!"

8. I’m sold!

9. Really?

11. Especially this

12. Don’t you worry

13. *Fully-managed your serverless architecture
*Required to use CloudForma"on
*Build-in support for CI/CD workflows

14. * Golang-based framework
* Deployment op"mized
* Concurrent for quick deploy

15. * Deployment u"lity, not a framework
* Extensions for new features
* unit-test Lambda func"ons

16. “Serverless is like ice cream.
It’s nice to talk about it, but
much be"er to try out.”

},
{ success: 201 }
)

24. Third Act...
