DevOps means something different to every organization in terms of culture, best practices and tool pipelines. And that's a good thing.
"Now, we have a lot of enterprises [to provide DevOps examples]. We don't only want to rely on what works for the unicorns," said Patrick Debois, co-author of The DevOps Handbook, a guidebook for DevOps implementation. The balancing act for DevOps best practices, tool recommendations and other advice is to make it broad enough for diverse IT teams to apply it successfully, not just companies with deep Agile and IT technical expertise paired with vast resources and flexible roadmaps. According to The DevOps Handbook co-author Gene Kim, enterprise IT shops are more like horses than the unique early DevOps adopter unicorns.
For teams unsure of where to start -- or those that have plateaued without a clear path to more improvements -- these before and after DevOps examples from real IT organizations yield insights into processes used, metrics for success and common mistakes and delays.
1How they did it-
Successes and struggles of DevOps transformations
These real-world DevOps examples from IT and software development professionals are gritty, not idealistic. Enterprises carry legacy IT baggage, have compliance obligations that push apart collaborative efforts and have learning periods for new technologies that must account for time spent actually running existing applications and infrastructure with today's tool set.
2Put ideas into motion-
Creating a CI/CD and agile infrastructure
While DevOps examples vary from company to company, there are some key tenets and practices that all organizations use as a common basis for implementation. Continuous delivery, configuration management and automation are the go-to choices, while immutable infrastructure and NoOps push the possibilities for organizations that are ready for radical infrastructure change.
An 18-month-long process solves an 18-month-old problem. Use continuous delivery instead of, or as a companion to, large-scale changes to make IT more dynamic and agile. Continue Reading
Test automation facilitates rapid code development and deployment as a means of attempting to mimic the production environment to prevent surprises on live systems. To make tests more effective and faster, listen to these requests from an automated testing engineer. Continue Reading
Infrastructure as code (IaC) enables a DevOps shop to frequently change the IT resources supporting agile applications, but it's a concept that IT pros struggle to put into action. Continue Reading

Monitoring in a DevOps environment
Much like the Japanese concept of kaizen, DevOps promotes a culture of nonstop change and improvement. Iterative development, proven code and smooth deployment get the application to production, while monitoring provides feedback that will direct further development and infrastructure improvements.

How to create a DevOps team bond
DevOps implementation doesn't happen overnight, and it also doesn't have to happen in the dark. Whether through articles, blogs and books; formal training and certifications; or peer-to-peer sharing, DevOps professionals can learn what their roles entail and how to work together.
Mapping out the value stream of a given project is a valuable process to ensure you get the most out of your deliverables. It brings in members from every step of the life cycle to identify problem areas, allowing them to be smoothed out in advance. Continue Reading
Hackathons are a fun, social way to get developers, line-of-business partners, IT administrators and architects, testers and others thinking creatively about technological capabilities. See how insurance company Aviva runs its annual event, and then schedule your own. Continue Reading
