Devops in a scaling environment is defined as AUTOMATION driven environment for the establishment of Devops culture and choosing of appropriate tools. Significant features to Devops in a scaling environment:

• Culture - Devops culture is all about shared RESPONSIBILITIES which means a shift toward communication and collaboration across development, IT/ops and the business. It does not majorly focus intently on the tools but also how the team can work together for a great result.
• Tools - Devops tools plays an important role to achieve great result and good use of Devops tools bring efficiency and productivity. The DevOps MODEL relies on effective tooling to help teams RAPIDLY and reliably deploy. These tools automate manual tasks, help teams manage complex environments at SCALE, and keep engineers in control of the high velocity that is enabled by DevOps.
• Automation - Automation is the backbone of Devops strategy. It helps to reduce the manual effort and speed up the processes to release the software continuously. It is the process of scripting environments — from installing an operating system, to installing and configuring servers on instances, to configuring how the instances and software communicate with one another, and much more.
• Communication and Collaboration - The success of DevOps automation hinges on effective communication and collaboration. Strong communication between team members is vital if those common goals are going to stay relevant for all parties going forward and embracing true collaboration in the workplace can drive positive change in how people work together.
