DevOps principles

The 7 key DevOps principles are the basics to begin your journey in DevOps methodology. DevOps is a culture that combines operations and development. The drawback of traditional banking is eliminated by DevOps which provides benefits such as integration of operations and development, faster time to market, frequent releases, and no silos in any of the phases, reduction in cost, and faster delivery time. The DevOps culture helps to manage, control, track, and monitor the DevOps Life Cycle Management efficiently and with ease. DevOps culture brings in the motivation, accountabilities, responsibilities, commitment, transparent communication, and increased collaboration in the team members. StarAgile provides the best DevOps training in the software development industry.

Due to frequently committing the codes in the version control repositories the plan, code, build, test, release, deploy, operate and monitor of the codes takes place with frequent intervals and thus avoids a last-minute change in the production or during the operations of the software. DevOps culture provides benefits such as the earliest bugs and error detection and solving such that there are fewer errors and bugs detected in the last phases of the DevOps Life Cycle Management. DevOps pipeline with continuous development, configuration management, continuous integration, continuous testing, continuous deployment, continuous operations, and continuous monitoring provides automation at every phase. CI/CD pipeline also called continuous integration and continuous delivery is the backbone of the DevOps culture.  

3 core DevOps principles

The 3 core basic principles of DevOps are as follows,

1. Automation - The first core DevOps principles is automation. Most of the companies find it hard to realize this as they focus on faster delivery to market and cut corners to do so. It may seem effective in the short term but disastrous in the long run. This may result in loss of customers and heavy price in reworking and fixing the bad codes. The automation in every phase of the DevOps cycle is a must and the first step in achieving the DevOps culture. Failure to do so may result in poor codes, an increase in delivery time in the long run, and application downtime in the production.

2. Tools - Since the DevOps culture is about automation and integrating all the phases the selection of tools that suits your requirement in the organization is a must. The tools must be selected based on team acceptance, project strategy, project goals, and cost and how do you manage the DevOps tools. Whether do you need a dedicated team to customize the custom tools or are you willing to engage with the out-of-box tools is your game. But the main thing is tools need to automate the process, with less cost and less overhead and the entire team must benefit from the tools that you choose.

3. Culture - Does DevOps foster transparent communication, enhance collaboration, enhance trust, show accountability and responsibilities in their work is the key to good DevOps culture implementation. The DevOps culture must truly integrate all the phases of the DevOps life cycle. You must have a DevOps advocate in the CIO's team in your organization. Team acceptance of the DevOps is the key to successful DevOps culture implementation at the grass-root level. Learn and explore of these principles with DevOps learning at StarAgile. The diagram below represents the key DevOps cultural aspects that need to be nurtured at every level of software development and operations.

7 principles of DevOps 

The 7 DevOps principles include the following,

1. Frequent releases - One of the main and DevOps principles is that the code must be committed in the version control repository very frequently and the same code must be tested and released to production frequently. This is part of DevOps culture to unify all the phases in the DevOps life cycle. This will produce fewer errors and bugs in the end. The bugs and errors are corrected with every code release at the early stage and a refined codebase is the ultimate aim of this first principle.

2. Customer-oriented action - The next principle of DevOps is to fulfill the goals and requirements of the projects by keeping the customer in mind and meet the expectations of the customer. This is done by adapting to the changes and scope of the software. Customers must be the prime focus while developing the DevOps cultural strategy. This enhances the team capability and directs the team to achieve and surpass customer goals and requirements.

3. Creating the software with the end in mind - This is the third principle of DevOps in which all the team members are aware of the progress made and what is operations team, development team, and testing team is doing so that code is ready with faster releases. There is no separation in the minds of the team members and they know what each other is doing in terms of technical and functional requirements and are working together to build the software. One of the key mindset in this principle is the shared goals among the team members.

4. End to End Responsibilities - The key thing is that every member of the DevOps culture knows what they are doing and what their contribution is and how they can manage the responsibilities from the start to end. Each member of DevOps is entrusted with the end to end responsibilities to accomplish the software with the shared goals. Each member is involved from the scratch till the end of the life of the product. There is no distinction between the operations and development and testing teams. All of them work coherently to engineer a great product. Enroll in DevOps online training to learn more about DevOps principles, practices, and DevOps engineer skills

5. Cross-functional autonomous teams - The teams adopting DevOps culture must be a truly independent team of DevOps professionals with a mixed and balanced set of skills so that each team member is matured to manage a lot of skills apart from the prime skills required for their action. There is no traditional tile of coding or tester or sysadmin, but only DevOps professional titles.

6. Continuous Improvement - It also means that adapting to changes, changes in the technology, changes in the scope, and changes in the customer expectations and improves with a small step each cycle. DevOps culture has a strong focus on continuous improvement to minimize waste, take less time and easy delivery, and optimization of the cycle thus improve every activity. So the desire to experiment must be inculcated in principle in the DevOps culture. Register for the DevOps course online at StarAgile and take up the training at the comforts of home and office.

7. Automation - One of the core values and the last DevOps principles is to make automation in every phase and every activity that is done in DevOps culture. Bring in the automation at every step that the DevOps professionals do to achieve the targets or goals. Think of automation in the CI/CD pipeline and every phase of the DevOps life cycle management. Not only has this even in the management of servers or infrastructure there needed to be automation in the way those are configured and managed.
