What is DevOps Methodology?
DevOps is a software development methodology that supports the integration and collaboration of software development (Dev) and information technology operations (Ops) throughout the entire service lifecycle.
This approach spans from the initial design phase through the development process to ongoing production support and maintenance.
The overall goal is to create an environment that promotes seamless collaboration, transparency, and shared responsibility between these two traditionally distinct domains.
Because of DevOps, releasing new big projects and software has become easy and smooth for sectors. The combination of DevOps and agile development methods helps to develop and release projects from time to time.
Categorization and programming partitions facilitate development and implementation. With the time and best practices of the DevOps methodology, new functions and features can be added to projects quickly and efficiently.
How DevOps works: the DevOps life cycle
The DevOps life-cycle is often depicted as the continuous delivery pipeline when portrayed linearly. It includes a series of iterative and automated development processes. These are part of a more extensive, mechanical, and iterative development life-cycle.
The primary aim is to optimize the swift delivery of high-quality software. The following six workflows constitute the DevOps lifecycle:
1. Planning(Ideation)
2. Development
3. Integration (or Build, or CI/CD)
4. Deployment (Continuous Deployment)
5. Operations
Post-deployment activities ensure smooth feature operation in the production environment. We monitor feature performance, behaviour, and availability and address incidents promptly. We provide the overall health of the network, storage, platform, compute, and security.
6. Learning (Continuous Feedback)
Three additional continuous workflows interweave throughout these stages:
6.1 Continuous Testing
6.2 Security
6.3 Compliance
Address regulatory compliance from the planning stage throughout the development lifecycle. Ensure observability, traceability, and access in runtime operational environments. Auditability is crucial for compliance validation by third-party auditors.
The Goals of DevOps Methodology
1. Better Collaboration
2. Automation of Processes
3. Continuous Integration (CI)
Set up a continuous integration pipeline. This merges code changes from multiple members into a shared repository often. It also includes automated testing to find and deal with troubles early in the development cycle.
4. Continuous Delivery/Deployment (CD)
Achieve endless shipping by ensuring that code is always in a deployable category. For more advanced setups, enable non-stop deployment. This will robotically launch adjustments to manufacturing after passing a computerized evaluation.
5. Monitoring and Feedback Loops
Focus on non-stop monitoring of projects and testing. This provides real-time insights into performance and discovers capacity troubles directly. Implement comment loops to facilitate continuous development.
6. Infrastructure as Code (IaC)
Adopt machine-readable script files to manage coping with and provisioning infrastructure. This ensures consistency, repeatability, and efficiency in infrastructure automation.
7. Quick and Reliable Software Releases
Aim for more rapid improvement cycles. Make sure software program releases are brief, reliable, and meet people’s expectations for regular updates and characteristic upgrades. Do not compromise performance or availability.
The Major Benefits of Using DevOps
1. Fewer Silos and Improved Communication

5. Enhancement to the Software Delivery Pipeline
Optimization of the entire software delivery pipeline, including builds, validations, and deployment processes.
6. Automation Reduces Menial Work
Automation of repetitive tasks leads to a decrease in manual and menial work.
7. Streamlined Development Processes
Streamlined development processes by fostering increased responsibility and code ownership among development teams.
8. Broader roles and skills
Developing more comprehensive skill sets and roles allows team members to contribute to various aspects of the software development lifecycle.
Which Tools and Platform Right for DevOps
Typically, DevOps practitioners utilize a CI/CD pipeline, containers, and cloud hosting. The tools belong to categories like open-source, proprietary, or supported distributions of open-source technology.
They do this by maintaining version-controlled source code repositories. In a CI/CD pipeline, committed code changes in version-control repositories trigger subsequent steps. CI/CD pipeline engines automate the validation and delivery of applications throughout the development life cycle.
Configuration management tools like Puppet and Chef enable the provisioning and configuring of software, middleware, and infrastructure.
They use predefined scripts or templates. Cloud environments are often adopted concurrently with DevOps practices. They allow for automated deployment and scaling tasks.
Public cloud providers like AWS CodePipeline and Azure DevOps offer cloud-based deployment pipelines. They provide pre-integrated services for managing workloads. Additionally, the DevOps-as-a-Service model delivers a suite of tools.
The tools seamlessly cover the entire process of code creation, delivery, and maintenance. It fosters collaboration between software development and IT operations teams.
Skill Sets Required for DevOps Developers
DevOps developers, also known as DevOps engineers, must consistently implement and maintain DevOps practices with technologies. Here are some key skill sets required for DevOps developers:
1. Version Control Systems (VCS)
Understanding of distributed version control systems such as Git. Experience with branching, merging, and pulling requests.
2. Infrastructure as Code (IaC)
Proficiency in IaC best practices tools like Terraform, Ansible, or Puppet. Ability to define, manage, and version infrastructure configurations.
3. Containerization and orchestration
Familiarity with containerization technologies like Docker. Experience with container orchestration tools like Kubernetes, Docker Swarm, or OpenShift.
4. Cloud Platforms
Proficiency in cloud platforms like AWS, Azure, or Google Cloud Platform. Understanding of cloud services and resource provisioning.
5. Agile and DevOps Culture
Understanding of Agile development methodologies and the principles of the DevOps culture. Collaboration with development and operations teams is needed to achieve common goals.
DevOps developers are bridge-builders between development and operations teams. They are vast parts of the modern software development lifecycle. These are all the basic skills needed to make your career in DevOps development.
