Architecting for Continuous Delivery and Zero Downtime

Arkitektur & Design DevOps

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