What Do You Mean I Need to Know DevOps?
So your team successfully deployed an application into production. Hooray, right? Several days later, the server is experiencing a high load. Software is deployed to the test environment and testers can’t login to the application. Explanations heard: “It works on my machine…” “It’s not the server…” “It’s your code…” Who do you turn to? Dev or Ops? What’s the difference?
In DevOps, Dev is the development team that introduces innovation to get it into users’ hands quickly. Dev works with Ops (Operations Team) to understand the production environment that their product will run on. Dev needs to understand the system and enterprise architecture, and test to see how the application performs in those conditions. Ops, on the other hand, makes sure users have access to a stable, fast, and responsive system. It needs to know what code is coming and how it will affect their system. Ops must monitor everything, including the code, through the environments an organization may be running: Dev > Test > Integration > Prod.
So why is the concept of DevOps all the rage? Latest research shows that organizations that incorporate DevOps practices simply get more done. With a single team representing cross-functional members all working together, DevOps organizations can deliver with speed, functionality, and innovation.
DevOps is an effective response to the challenge that nearly every IT organization is under pressure to respond more quickly to business needs AND provide stable, secure, predictable IT services… although the different functional delivery teams are typically not organized for, or focused on, the same success criteria.
Organizational culture in which communication and collaboration are promoted across the development, quality assurance (QA), IT operations and information security teams enable faster “ship-to-production” performance.
With DevOps, organizations can create a work system where small cohesive teams can quickly and independently develop, test, and deploy code and value safely, securely, and reliably to customers. DevOps requires operations staff to adopt many of the same techniques as developers for their systems work. DevOps itself is constantly evolving.
To gain the benefits of DevOps, you first must have a culture that can support it. The culture must favor collaboration and embrace integrated relationships. It promotes engaging early and often, asking questions, breaking out of silos, and being open – and frowns on finger pointing. The culture encourages open communication, in which cross-functional teams create shared processes and decisions.
Ultimately, the culture is an inclusive environment in which all functional groups have skin in the game to make DevOps work. In this culture, DevOps can take root, grow, and prosper.
