What is meant by DevOps?

Description of the image

DevOps is one such set of tools and practices that has boosted the software development industry since its introduction and is, therefore widely adopted by companies.

Advancing with strides, the software development industry has come a long way and yet faces the challenge of supplying advanced software to an increasingly digitized world. The software development market is expected to reach $1039 million by 2027, and as such, there is a wide demand for newer software by businesses and individuals worldwide.

To meet with this demand, software development businesses are adopting different methods and tools that can help them shorten the development time without compromising on the software quality.

Introduction

The term DevOps is a union of 2 words, the Development (Dev) and IT Operations (Ops) involved in software development, guiding them to collaborate for an efficient and streamlined software development process or lifecycle.

DevOps is essentially a set of essential principles that are supported by tools, enabling both teams to work together at all stages of the development process, right from planning to operations. 

DevOps principles enable collaboration and coordination between different departments involved in software production. This helps streamline the process with continuous feedback, preventing the software from moving between its different stages.

Started in 2007, DevOps has made way for a modern method of software development that stands on the pillars of cross-team communication, collaboration, automation, and team empowerment.

How Does DevOps Work?

Under DevOps, both developers and the IT operations team collaborate throughout the software development lifecycle, therefore introducing a cultural shift that helps improve the speed of software development. 

Merging together as a single team, the software can be scrutinized by experts at all stages, from development to testing to operations. In addition to a continuous communication and feedback loop, DevOps also encourages the use of tools to help automate and accelerate processes.

Through automation, teams can not only save time on repetitive tasks but also ensure reliability and error-free software.

Moreover, continuous integration and continuous delivery enable quicker software deployment, leading to more frequent updates and changes that help meet market trends and demands. 

DevOps also aims to include essential parameters, such as security, in the development process. Through its principles, DevOps can ensure quality and agility in software development and deployment.

The Lifecycle of DevOps is?

With the adoption of DevOps, a software development lifecycle can be divided into the following phases. However, remember that with continuous integration, development, and feedback, there is no clear distinction between these processes, and their overlapping is what helps streamline the software release.

Discovery

As a team, you must start by brainstorming ideas to explore, prioritize, and organize the features that the software must include. These ideas should align with the strategic goals and customer needs. 

Planning

Once you have the guidelines for the software you wish to produce, you can start planning the development process. Adopting agile practices that help break the work into smaller pieces to deliver incremental value can help improve speed and agility. 

Development

The next step is to start developing the software. For this, you can use tools that help code and build the software. DevOps practices suggest a continuous development strategy wherein the coding, testing, and integration overlap each other with the help of feedback and monitoring.

Building And Integration

An essential practice of DevOps, continuous integration is a methodology that provides developers with easy access to software code. Under this practice, developers are required to upload up-to-date codes into a common repository.

This allows multiple developers to work together. In addition, the availability of common code prevents repetitive manual work through automation, ensuring a better software development speed. 

Testing

Overlapping with the development stage and continuous testing of the software helps ensure that the code is working properly. Tools help developers and operations teams automate the testing process, allowing each change in the code to be tested in different environments.

This allows the teams to easily detect bugs and errors, rectify them early on in the process, and prevent software failure. 

Feedback And Monitoring

Another essential pillar of DevOps is continuous monitoring of the development process, which helps ensure an error-free process and system. In addition, continuous feedback plays a vital role in integrating the customer's demand and maintaining the system's credibility.

To ensure proper feedback, it is vital to automate the monitoring process. The teams work together to generate reports that can help improve future releases. 

Delivery

Through continuous delivery, software companies can periodically ensure sustainable updates for end users. Moreover, this helps automate the product release since testing is also automated. 

Deployment

Similar to continuous delivery, continuous deployment enables a better version of software to reach the end user. However, this practice is preferred, as every validated change is automatically released to the end user without a release date being set. 

Continuous deployment also helps improve the feedback loop, as developers can judge the result of each change rather than releasing all the new code at once. 

Observing

Overlapping with software delivery or deployment, this refers to the identification and resolution of issues that can impact product speed, uptime, and functionality. It is essentially an extension of continuous monitoring that helps detect changes, failures, and high-risk actions that can impact the software's functioning.

The DevOps lifecycle is ultimately based on DevOps best practices and principles that include:

  1. Continuous integration
  2. Continuous delivery or deployment
  3. Continuous monitoring and feedback
  4. Agile practices
  5. Infrastructure as code
  6. Communication and Collaboration 

Conclusion

DevOps is a set of practices, tools, and guidelines that help merge the software development and IT operations teams involved in software production. Helping increase communication and collaboration between the two teams, it ensures a quick and efficient release of high-quality software.

The DevOps lifecycle is like an infinite loop, with practices overlapping each other to ensure that the software is reliable at each stage, preventing error rectification during release, which can cause delays.

By adopting DevOps practices, any software development company can achieve a faster time to market, easily release new updates, and, therefore, keep up with the client's demands.
