Serverless architectures let you build and deploy applications and services with infrastructure resources that require zero administration. In the past you had to provision and scale servers to run your application code install and operate distributed databases and build and run custom software to handle API requests. Now AWS provides a stack of scalable fully-managed services that eliminates these operational complexities. In this session you will learn about the the basics of serverless and especially how your business can benefit from it.

The increasing pace of change in software development requires
organizations to restructure their efforts and split their applications into
microservices in order to keep up.
The more they can independently evolve parts of their increasingly
complex systems at scale, and decouple their innovation (applications and
user experience) from infrastructure management, the better positioned
they will be to serve their customers.
Why are we witnessing a paradigm shift?

What is
Serverless?

9. © 2018, Amazon Web Services, Inc. or its Affiliates. All rights reserved.
“At the heart of serverless computing is a simple but
revolutionary idea – that companies only pay for compute
when they actually use it.”
