DevOps: Definition, Types, Working, DevOps tools, Advantages, Disadvantages



DevOps is the combination of cultural philosophies, practices, and tools which increase the organization to deliver applications and the service at a high velocity using traditional software development and the infrastructure management process. It should be able to automate the app performance monitoring, infrastructure, and configuration among others. It is closely linked with the ability to knowledge about the DevOps toolset, coding, and scripting.

Goals of DevOps

The main aim of DevOps is to optimize the flow of value from the idea to the end-user. There is a cultural change that happens For a company to be very successful with DevOps, the culture is the main focus but the DevOps goal is to make the delivery of the value more efficient and effective. This closer relationship between Dev and Ops in every phase of the DevOps lifecycle from the build, test, and release phases of the development operations and monitoring. So the relationship improves the feedback loop and the deployment. The result of these can be more rapid, continual to the release of necessary feature changes or additions.

Types of DevOps

Continuous integration (CI)

It may include different steps related to the execution of the test process. The clients also provide information to incorporate adding new features to the application. Most of the changes that happen in the source code during this phase become the hub for frequent changes on a daily or monthly basis. Building code is a combination of unit and integration testing, and code review and the developers can make frequent changes to quickly spot to resolve at an early stage. Due to this continuous development, the updated code integrates within the entire system.

Continuous testing

The next step in this type is the testing phase where the developed code is tested for bugs and errors to make their way into the code. It plays a major role in checking the usability of the developed software. The successful completion of this process is important in determining whether the software meets the client’s specifications. It enables continuous testing to analyze multiple code bases simultaneously. It ensures that there are no flaws in the functionality of the developed software. The automated testing is done on automation tools like selenium after the reports are generated on another automation tool.

Continuous deployment

It ensures product deployment without affecting the application performance. It is important to deploy all the available services during this phase. This process eliminates the need for scheduled releases and accelerates the feedback mechanism to address the issues more quickly with greater accuracy. A containerization tool helps to achieve consistency across tests, development, staging, and production environments. It is guaranteed to benefit the organization to test the environment in place. Configuration management holds a lot of value and involves configuring and maintaining consistency in the functional requirement of the app.

Continuous monitoring

To monitor the performance of the software product, it is essential to determine the overall efficiency of the product output. The continuous monitoring process can give important information about the developed app and identify the general patterns and gray areas that need more focus. It is an operational phase in which the objective is to enhance the overall efficiency and monitor the performance of the app. It also maintains the availability and security of services. Network issues and other problems are fixed during this phase at the time of their detection. Due to this, continuous monitoring can proactively check the overall health of the system.

Continuous feedback

It is essential to analyze the outcome of the application. It is used to set the tone for improving the current version and releasing a new version based on the stakeholder feedback. The overall process can be only improved by the results from the software applications. The information is significant as it carries all the data about the performance of the software to suggest to the end-users of the software.

Working procedure

DevOps is a method that is meant to improve the work throughout the software development lifecycle. It is processed as an infinite loop comprising plan, code, build, test, release, monitor, and reset the loop. It means that the IT team’s software perfectly meets the user’s requirements to deploy without any wasted time and runs smoothly the first time. Organizations use a combination of culture and technology to align software to developers and stakeholders to communicate about the project and developers work on small updates from one step of development and deployment to another. Team reviews can change immediately to enforce policies to ensure releases meet standards.

It is very easy to write the software quickly, writing software that works is another story. DevOps adherents use containers to make the software behave the same way as the development through testing and into production. They deploy changes individually to rely on configuration management for consistent deployment and hosting environments. In order for developers to support the live software, it is incumbent on them to integrate runtime considerations into the software design meetings and offer guidance on how to get the most out of the resources. The more these specialists collaborate and share skills to foster a DevOps culture.

DevOps tools

Code responsibilities

The version of the controlled source code can be enabled by multiple developers to work on code. Developers can easily check out and they can revert to the previous version of the code and keep a record of modifications to the source code without tracking the developers to follow which changes are recent and which versions of the code are available to end-users. Tools may include Git and GitHub.

Artifact responsibilities

The source code is compiled into an artifact that for testing and enables version-controlled object-based outputs. It is a good practice for the same reasons as source code management. DevOps teams can deliver applications to the end-user during the development lifecycle. The tool initializes the developers to create tests and validate code in a shared repository as needed without manual work. common tools for CI, CD includes GitLab and circles.


As an isolated software environment on a shared OS, it provides an abstraction layer to enable code to work on the same underlying infrastructure from development to testing, staging, and production.. It is the most well-known containerization software to offer specific windows container options.

Configuration management

Configuration management systems enable IT to provision and configure software, middleware, and infrastructure based on a script or template. The DevOps team can set up deployment environments for software code releases and enforce policies on servers, containers, and VMs through a configuration management tool. Changes to the deployment environment can be version controlled and tested, so DevOps teams can manage infrastructure as code. Configuration management tools include Puppet and Chef.

Advantages of DevOps

  • Higher productivity.
  • It increased product quality.
  • It improves flexibility and support.
  • It reduces the chance of product failure.
  • Clear product vision within the team.

Disadvantages of DevOps

  • Dealing with the legacy system is a challenge.
  • Getting the right pool of DevOps expertise is a challenge.
  • Transition challenges.
  • Practicing security for CI/CD is a separate affair.
  • Lowered the business security by outsourcing the DevOps operations.
