Serverless is the new black - I can deploy my application to the cloud without ever worrying about infrastructure. We all remember the days when we had to spend hours and hours configuring and debugging web servers when all we wanted was to just code and test our app. Those days are long gone and it’s time for us to unlearn how to provision and manage infrastructure while focusing on building and scaling applications.

14. @simona_cotin–Martin Fowler
“Serverless architectures refer to
applications that significantly
depend on third-party services
(knows as Backend as a Service
or "BaaS") or on custom code
that's run in ephemeral
containers (Function as a Service
or "FaaS")”

27. @simona_cotin
“Serverless computing has made
its way into the enterprise because
it simplifies deployment and
allows developers to focus more
on application features than on
tasks such as provisioning VMs.
Emerging uses for serverless
technology include image
processing, task management,
workflows and notifications.”

Why Node.js?

29. @simona_cotin
•Javascript has a rich
ecosystem of libraries
and tools
•Enable FE developers to
build scalable backends
•Large use base -
javascript is the English
of languages
Why Node.js?

30. @simona_cotin
•Lightweight - helps reduce
cold start
•Commonly run in a
distributed, horizontally
scaled fashion
•Scripting means no
compilation required to
start from a portal
•Runs equally easy on most
OS’s
Why Node.js?
