Participants should plan to attend both days of training course. Note: to attend training courses, you must be registered for a Platinum or Training pass; does not include access to tutorials on Tuesday.

Peter Jausovec details fundamental building blocks of the next-generation cloud native apps. You'll learn to decide on containers versus functions, which communication patterns to use, how to set up development and debugging environments, CI/CD pipelines, and to monitor and observe your applications using key metrics through theory, demos, and exercises, using Kubernetes.

What you'll learn, and how you can apply it

By the end of this two-day training course, you'll understand:

What makes an application a cloud native application
How to get started designing and building cloud native applications
Understand when to use containers versus functions

And you'll be able to:

Set up the environment for development and debugging, CI/CD pipelines for builds and deployments, and monitoring for key application metrics
Decide on communication patterns
Use a service mesh to do zero-downtime deployments, A/B tests, and canary deployments

Who is this presentation for?

You're a software developer or architect who wants to get an overview of cloud native development and principles and start developing cloud native applications.

Level

Beginner

Prerequisites:

A basic understanding of containers, Docker, and Kubernetes
Familiarity with at least one of the popular programming languages such as C#, Java, Go, or JavaScript

Hardware and/or installation requirements:

A laptop with Docker and Kubernetes installed (You can either use Minikube or Docker for macOS or Windows or a managed Kubernetes solution from one of the cloud providers.)
