Practical DevOps

Overview of this book

DevOps is a practical field that focuses on delivering business value as efficiently as possible. DevOps encompasses all the flows from code through testing environments to production environments. It stresses the cooperation between different roles, and how they can work together more closely, as the roots of the word imply—Development and Operations. After a quick refresher to DevOps and continuous delivery, we quickly move on to looking at how DevOps affects architecture. You'll create a sample enterprise Java application that you’ll continue to work with through the remaining chapters. Following this, we explore various code storage and build server options. You will then learn how to perform code testing with a few tools and deploy your test successfully. Next, you will learn how to monitor code for any anomalies and make sure it’s running properly. Finally, you will discover how to handle logs and keep track of the issues that affect processes

Okay, but what about DevOps and the IoT again?


Let's take a step back. So far, we have discussed the basics of the Internet of Things, which is basically our ordinary Internet but with many more nodes than what we might normally consider possible. We have also seen that in the next couple of years, the number of devices with Internet capability in some form or another will keep on growing exponentially. Much of this growth will be in the machine-to-machine parts of the Internet.

But is DevOps, with its focus on fast deliveries, really the right fit for large networks of critical embedded devices?

The classic counterexamples would be DevOps in a nuclear facility or in medical equipment such as pacemakers. But just making faster releases isn't the core idea of DevOps. It's to make faster, more correct releases by bringing people working with different disciplines closer together.

This means bringing production-like testing environments closer to the developers and the people working with them...
