Are you attempting to get a better handle on what is DevOps? Here are the eight foundational theories you need to understand!
DevOps has become an overloaded buzzword that means a lot of different things to a lot of individuals. That is a challenge when you are working to understand what DevOps is or define DevOps. Rather than attempting to define DevOps, we are going to describe the foundational notions that distinct Men and Women associate with DevOps along with the history of the DevOps movement evolved to help you get a holistic perspective:
Who Would DevOps Come?
DevOps is the offspring of agile software development -- born from the necessity to keep up with the greater software velocity and throughput agile methods have attained.
Agile Development is an umbrella term for many iterative and incremental software development methods.
They all fundamentally incorporate iteration and the continuous feedback it provides to successively refine and provide a software system. They all involve continuous planning, continuous testing, continuous integration, and other forms of the continuous evolution of the project and the software. They're all lightweight, particularly compared to conventional waterfall-style processes, and inherently adaptable. And what is most important about agile methods is that they all focus on enabling people to collaborate and make decisions together quickly and effectively.
In the beginning, agile teams were mostly composed of developers. As these agile teams became effective and efficient at generating applications, it became evident that having Quality Assurance (QA) and Dev as different teams were ineffective. Agile climbed to encompass QA to increase the speed of delivering applications and nimble is once again rising to encompass the delivery and support members to expand agility from ideation to delivery.
The DevOps ideals extend agile development practices by further streamlining the movement of software change thru the construct, support, and deploy and delivery phases, while enabling cross-functional teams with complete ownership of software applications -- from design thru generation support.
DevOps is an IT mindset that encourages communication, cooperation, automation, and integration among software developers and IT operations to enhance the quality and speed of delivering software.

DevOps teams concentrate on standardizing development environments and automating delivery processes to improve delivery predictability, efficiency, security, and maintainability. The DevOps ideals provide developers more control of their production environment and a better comprehension of the manufacturing infrastructure. DevOps encourages empowering teams with the freedom to construct, validate, provide, and support their particular programs. With DevOps, nothing has"thrown over the wall."
Ahead of DevOps program growth, teams were accountable for collecting business requirements for a software program and writing code. Then a separate QA team tests the program within a remote growth environment, if requirements were fulfilled, and releases the code for surgeries to deploy. The deployment teams are further afield into siloed groups such as databases and networking. Every time a software application is"thrown over the wall" into an independent team that it adds bottlenecks.
