Chapter 4. DevOps as a Service

This chapter is going to cover various topics related to the DevOps world. We are going to look at DevOps in the context of Site Reliability Engineering (SRE), as automation and DevOps play an important role in this area. We will be integrating our system with monitoring solutions to collect various metrics to improve our services. This chapter will cover recent trends in this domain and give an idea about the expanding market of DaaS providers. We will also provide a brief introduction to various topics related to DaaS.

We are going to cover the following topics in this chapter. This should give us an idea about what exactly DevOps means to the agile world:

What is DaaS?
One-click deployments and rollback
Configuring automated alerts
Centralized log management
Infrastructure security
Continuous process and infrastructure development
Continuous integration and continuous development
Collaboration with development and QA teams

What is DaaS?

DevOps-as-a-Service (DaaS) is a service that allows you to get all the compilation, building, and Continuous Integration (CI)/Continuous Development (CD) tool chains setup instead of having to setup your own. DaaS can be provided by an internal team. In this case, the development team won't take any direct actions to manage its infrastructure; it will just feed its code to get compile, build, and CI/CD features. Alternatively, DaaS can be provided by external vendors, in a market that is expanding rapidly. These can help with your journey to achieve CI and CD.

In 2016, Gartner declared that 25% of 2,000 global companies that are surveyed will be using DevOps. However, this year, Forrester research has said that this will reach 50%. According to a study by cloud management provider RightScale,

the ratio of enterprises that have adopted some aspects of DevOps principles reached 84% in 2017

There are multiple websites that list all the major DaaS vendors. The following are among...

Collaboration with development and QA teams

As the name DevOps suggests, DevOps refers to a combination of development and operations teams who come together to complete a business project successfully. DevOps refers to the collaboration of teams that are involved in the development, delivery, and maintenance of a project to make it faster and more efficient in every dimension. Our main focus inDevOps is on the development and quality analysis teams. This is due to the CD and the delivery of new builds.

In today's competitive world, a new innovation or idea is hot property, that everyone wants to cash in on quickly. This need to deliver a new product rapidly leads to an additional load on developers to create new features that need to be optimal in every sense. This may lead the code to break, causing the entire application to shut down. A faulty deployment, in turn, may cause the application's configuration to break, which may be non-recoverable.

Summary

DevOps as a service is an emerging philosophy in application development. There's not one path to setup DevOps as a service. It varies from organization to organization, and you need to decide what works in your organization. Many organizations adapt DaaS to manage their application to the cloud. By using DevOps as a service, we can automate build, test, and deploy processes. We can achieve this by implementing effective CI and CD process. In this chapter, we have learned how to setup one-click deployment and rollback using the Jenkins tool. Throughout this book, we have been focusing on microservices, and we have seen how to collect and send automatic monitoring alerts. We learned how to setup Jenkins and GitHub to achieve CI and deployment end to end. This is going to help us improve the engineering pipeline and improve the delivery process. We have also discussed collaboration between development and QA teams.

We can conclude that the DevOps life cycle contains development, testing...
