What is DevOps Definition?
In the world of software engineering, DevOps Definition is a brand new term. DevOps concept is the combination of two properties: Development and Operations. DevOps is basically a practice that aims at integrating the process of software development and software operation.
The main emphasis of DevOps is over shortened developmental cycles, increased frequency of deployment and infrastructure management. This speed enables organizations to better serve their customers and compete more effectively in the market.
How DevOps Works
Under a DevOps model, development and operations teams are no longer “siloed.” Sometimes, these two teams are merged into a single team where the engineers work across the entire application lifecycle, from development and test to deployment to operations, and develop a range of skills not limited to a single function.
In some DevOps definition models, quality assurance and security teams may also become more tightly integrated with development and operations and throughout the application lifecycle. When security is the focus of everyone on a DevOps team, this is sometimes referred to as DevSecOps.
These teams use practices to automate processes that historically have been manual and slow. They use a technology stack and tooling which help them operate and evolve applications quickly and reliably. These tools also help engineers independently accomplish tasks (for example, deploying code or provisioning infrastructure) that normally would have required help from other teams, and this further increases a team’s velocity.

Benefits of DevOps Definition
Move at high velocity so you can innovate for customers faster, adapt to changing markets better, and grow more efficient at driving business results. The DevOps model enables your developers and operations teams to achieve these results. For example, microservices and continuous delivery let teams take ownership of services and then release updates to them quicker.
Increase the frequency and pace of releases so you can innovate and improve your product faster. The quicker you can release new features and fix bugs, the faster you can respond to your customers’ needs and build competitive advantage. Continuous integration and continuous delivery are practices that automate the software release process, from build to deploy.
Ensure the quality of application updates and infrastructure changes so you can reliably deliver at a more rapid pace while maintaining a positive experience for end users. Use practices like continuous integration and continuous delivery to test that each change is functional and safe. Monitoring and logging practices help you stay informed of performance in real-time.
Operate and manage your infrastructure and development processes at scale. Automation and consistency help you manage complex or changing systems efficiently and with reduced risk. For example, infrastructure as code helps you manage your development, testing, and production environments in a repeatable and more efficient manner.
Build more effective teams under a DevOps cultural model, which emphasizes values such as ownership and accountability. Developers and operations teams collaborate closely, share many responsibilities, and combine their workflows. This reduces inefficiencies and saves time (e.g. reduced handover periods between developers and operations, writing code that takes into account the environment in which it is run).
Move quickly while retaining control and preserving compliance. You can adopt a DevOps model without sacrificing security by using automated compliance policies, fine-grained controls, and configuration management techniques. For example, using infrastructure as code and policy as code, you can define and then track compliance at scale.

There are a number of sub-concepts under DevOps:
- CONTINUOUS INTEGRATION
The concept of DevOps involves unifying the application codes into the software repositories, commonly known as the repo, many times in a day. The continuous tools for unifying the application codes like Atlassian Bamboo and Jenkins and build tools like Maven and Ant are used together to verify the entered application codes.
Continuous integration helps the developers to report to a shared repository using an application or source code system like GIT.
- CONTINOUS TESTING
Continuous Automated Testing is required to ensure smooth and satisfying results. For automated testing, the need is to unify the required tools for constant integrated behavior. Constant testing is a pre-requisite condition for constant delivery. DevOps requires automated and repeated testing schedules that unify the processes of development and ensuring the absence of errors while enabling continuity.
- CONTINUOUS PROVISIONING OR CLOUD PROVISIONING
Virtual machines are available which are quite flexible and are payable as per their use. It would be beneficial to design a cloud instance that would unify various environments including testing, development, staging, and production.
- CONFIGURATION MANAGEMENT
If configuration management is to describe in simple words, it can be defined as a system of engineering processes of software that set the foundation of a software’s performing ability, functional and physical characteristics. In the world of software technology, configuration management refers to the items or tools that conform and arrange the order of a project for its success.
The process of configuration management allows in creating a setting that runs consistently in all kinds of environment. Some of the popular configuration management tools are a puppet, Chef, and Ansible and these can be used to easily manage the resources in the cloud environment.

The process of configuration management in DevOps is made up of:
- SOURCE CODE REPOSITORY
- ARTIFACT REPOSITORY
- CONFIGURATION MANAGEMENT DATABASE
CONTINUOUS DEPLOYMENT OR DELIVERY
It is another continuous software practice or sub-concept of the DevOps software where the changes in the code are created by the software autonomously, are tested and then released for production. The process of continuous deployment relies on the process of continuous integration which happens by transferring all the changes in the application codes to a certified testing environment. It can be used for delivering package file that is ready to be transferred to any kind of testing or production environment.
