Summary
In this chapter, we learned about the difficulties faced by development and operations teams in a traditional environment and how agile development helps in such a scenario. What has changed after the arrival of agile development and what challenges has it brought with its arrival? We have covered the important aspects of the DevOps culture, including continuous integration and continuous delivery. We also covered details regarding cloud computing and configuration management that enhance the processes and help to adopt DevOps culture.
In terms of tools and technologies, we covered a brief overview of SVN, Git, Apache Maven, Jenkins, AWS, Microsoft Azure, Chef, Nagios, Zenoss, and the DevOps dashboard Hygieia.
In the next chapter, we will see how to install and configure Jenkins 2.0 and implement continuous integration using a sample Spring application available on GitHub.
It is the right time to quote Charles Darwin as it is relevant in the context of DevOps culture:
"It is not the most intellectual or the strongest species that survives, but the species that survives is the one that is able to adapt to or adjust best to the changing environment in which it finds itself."
