Serverless and Cloud Native Thinking

Software is evolving at a rapid pace, and new technologies like serverless allow us to build and operate applications in completely new ways. In this talk we will take a look at how we can leverage the cloud to build a modern application, different ways to pick components and why we should keep evolving our architecture.

1. Cloud-Native Thinking Serverless & Evolving your architecture Ben Bridts ben@cloudar.be @benbridts
2. Business Value
3. Cloud Principles • On demand • Pay only for what you use • Scale up and down • Remove undifferentiated heavy lifting
4. No one does conference talks about having benefited from multi-cloud, or having been hurt by not doing it Ben Kehoe Cloud Robotics Research Scientist at iRobot 2019
5. Cloud Principles • On demand • Pay only for what you use • Scale up and down • Remove undifferentiated heavy lifting
6. Business Value
7. Before Cloud
9. Serverless Principles • High Availability • No idle capacity (pay for value) • Flexible Scaling • No server management
