Architecting for Continuous Delivery and Zero Downtime

Overview

Continuous Delivery is all the hype these days. This training makes it a reality. We start with an overview of what Continuous Delivery is and how it can help you. We then quickly dive into the details. You will learn what it takes to architect a Java application so that it can be delivered continuously into production, with code, configuration and database delta, multiple times a day, with Zero Downtime.

Buckle up! This class is intensive and hands-on. You build an entire Java web app to the point where it deploys continuously, with zero downtime. We tackle the hard problems with a battle-tested approach you will be able to apply immediately.

If you are an architect or a developer and want to gain a solid understanding of the techniques you need to make Continuous Delivery and Zero Downtime a success, this training is for you.

This training is brought to you by Boxfuse in cooperation with comSysto.

Prerequisites

This training assumes a good understanding of software architecture, the Java language, Linux and relational databases in general. 

Format

Bring your own laptop. You've heard someone talk the talk.This is where you walk the walk.

We start by a high-level overview of what it means and what it takes to architect an app for Continuous Delivery and Zero Downtime.

We then quickly move on and take a deep dive into the practical side of things. Over the course of 14 carefully crafted exercises you will gradually build out a Java web app to the point where it is released and deployed continuously with zero downtime. All this in a virtual data center set up on your own laptop to simulate real world interactions.

Finally, we wrap up with a look at where the industry is heading, with new exciting developments like Immutable Infrastructure.
