DevOps is the culmination of Development (Dev) and Operations (Ops). DevOps is the combination of people, process and technology to deliver to the customer applications and services faster and with higher quality than that of traditional software deployment and infrastructure. The faster delivery and higher quality helps to better serve customers and enables you to be competitive in the industry.
Need For DevOps
With DevOps the Development and Operations teams which had siloed roles, now work collaboratively to deliver applications that are more reliable. By adopting DevOps culture along with DevOps tools and practices, it enables the teams to respond to customer needs faster and also increases the confidence in the applications they have built thus reaching the business goals faster.
Benefits of DevOps
Apart from building a healthy relationship between Development and Operations teams, DevOps has brought in tremendous advantages in various stages of IT enterprise development.
Improved Security
DevOps enables early collaboration with security experts, leading to an increase in the level of security tests and automation to enforce quality assurance and provide better mechanisms for security management and compliance.
Stable Operating Environments
DevOps follows an integrated testing process which helps in the reduction of potential errors and defects – ensuring a stable release. Consequently, your business will have fewer downtimes compared to a traditional IT framework.
Cost Reduction
DevOps strategy’s biggest advantage from a business perspective is maximizing profits. Through CI/CD, DevOps ensures zero network downtime as developers produce more efficient code and identify and fix bugs immediately.
Fosters Innovation
DevOps methodologies help to automate repetitive tasks. This frees developers time, which can be used to brainstorm and enables them to better understand customer expectations. DevOps cultivates and encourages an environment where the developers are not restricted to a set of inflexible instructions.
Reduced Deployment Time
The fundamental reason for adopting DevOps is Continuous Integration (CI) and Continuous Delivery (CD), Continuous monitoring and rapid feedback loop. Being a natural evaluation of the Agile technique, it makes the software development process faster and more efficient.

Frequently asked questions
DevOps is the combination of Development and Operations practices in IT software development. It originated in the mid-2000 among IT professionals looking for ways to efficiently, innovatively, automate, and speed up the process of software development and delivery.
The developers’ team performs the software development, which involves writing the code, implementing, testing, and re-writing the code where required. The operations team works on providing the infrastructure to run the software. They work on determining the processing power required for the software, how to make the software secure, how to run the software efficiently and without any interruptions. DevOps help to make these teams work in tandem with each other.
The benefits of DevOps are as follows:
Technical benefits of DevOps
- Continuous software delivery
- Faster time to deploy
- Fosters innovation
- Less complex problems to manage
- Early detection and faster correction of bugs
Business benefits of DevOps
- Faster delivery of features
- Stable operating environments
- Lower failure rate of releases
- Improved communication and collaboration between the teams
- Efficient cost management
DevOps brings about a holistic approach to software development. Here the development and operations teams are not siloed. It uses a cross functional team consisting of developers, designers, operations, testers, and support personnel. Before starting on any project the team plans the entire software development cycle from design to delivery. The process is as follows:
Plan (Operations team)
- The operations team organizes the tasks and schedule
- The project manager sets up the necessary infrastructure management tools
Code (Developers and Sys Admins)
- The developers write the code
- Use source code management tools to review the code
- System administrators merge individual or siloed codes into one master code
Build (Software Engineers/ Architect)
- Build the application and source code in the required format
- Once the engineering team builds the source code, use CI/CD tools to verify code
Test (Testers)
- Test the application in test environment to ensure there are no bugs
- This will be part of the workflow to ensure high quality
Package (Delivery)
- Implement packaging tools (software repository tools) to coincide with business requirements and goals
- Validate the package and best practices
- Import packaging into a deployment tool
Release (Delivery)
- Manage code and feature changes
- Approval of software releases
- Release application for the larger audience
Monitor (Operations)
- Continuous monitoring of the application performance
- Monitor logs
- Maintain incident reports
The cost benefits of DevOps are as follows:
- With the reduced development time, the usage of infrastructure is reduced, leading to reduced costs.
- The continuous delivery model improves productivity with less staff, thereby reducing the expenditure on hiring personnel.
DevOps can be used in any industry that needs software delivery and releases. This includes almost all industries nowadays, as organizations use multiple applications for their various operations.
DevOps improve the application security in the following ways:
- Due to continuous communication between teams, DevOps maximizes the visibility in the software life cycle. This helps teams to spot flaws and bugs before moving to production.
- DevOps fosters task automation in the development environment, which improves consistency, quality and predictability. This reduces human errors, which are consistent in a manual process.
- Due to the faster development cycle, there is also faster debugging of the application. That is continuous development.
- By using standardized frameworks and automation tools, teams can adopt any safer and reliable tool for each stage of the development process. This prevents lock-in with outdated tools and frameworks.
- DevOps favors the use of microservices and containers for the development cycle. This helps in isolating and securing applications from external attacks.
DevOps is a team consisting of developers and Operation or support personnel. When you bring in your software Security team as part of the software development cycle, then the cross-functional team consisting of all three departments is called DevSecOps.
This practice tries to automate core security functions. These security functions and processes can be incorporated at the start of the development cycle than at the end.
CI/CD stands for Continuous Integration/ Continuous Deployment. Developers tend to work isolated and hence need to integrate their code with the remainder of the team’s codebase. While working manually, it will take days or weeks to merge the changes with the master code. This will result in merge conflicts, take time to debug, and create duplicated efforts. CI/CD automates and validates the build and testing process when a team member makes changes to a code, ensuring it is correct and stable.
Microservices are the method of breaking down an application into small components or packages. These packages will contain a single function module with defined operations and interfaces. This method helps in identifying and isolating bugs and errors. Also, it will be easy to update specific functionalities or packages instead of the entire application
Containers are a form of operating system virtualization that is formed between the application and the actual infrastructure used. A single container can be used to run a microservice or the entire application. It will contain all the necessary executables, libraries, codes and configuration files to run the application. Containers are lightweight and portable, which makes them easy to move between environments.
