The definition of DevOps is a bit vague and different definitions are mentioned in different sources. DevOps is created from the combination of two words Development and Operations. Before the concept of DevOps was introduced, development and operations teams were working separately in organizations.
The operation team was responsible for maintaining the software, and the development team was looking for adding new features to the product. With such an approach, adding new features to a software and testing the performance of these features was considered a time-consuming process.
DevOps increases the interaction between these two teams and reduces their distance. In this way, the processes that might take several weeks, sometimes reach results in a few hours, and facilities are provided to customers much faster. Simply put, DevOps creates two important values in the organization:
- Faster development
- Easier maintenance
Early stages of DevOps usually include continuous integration and continuous delivery (CI/CD), real-time monitoring, incident response systems (IRS), and creating platforms for cross-team collaboration.
Here we emphasize communication between development and operations teams, but the concept of DevOps has expanded over time and created a culture that includes communication between other teams as well.
In simple words, it can be said that DevOps creates a communication bridge between teams. With this definition, it is clear that DevOps is not a technology but includes culture, processes and tools. Simply put, DevOps creates a bridge between teams. With this definition, it is clear that DevOps is not a technology, but includes culture, processes and tools.
DevOps has different methods and using different tools, it helps you to implement software development processes better and faster. For example, the GitOps method is one of the software development methods in the Cloud environment for large teams, which greatly simplifies the development process and its necessary coordination.
The most important concepts of DevOps
If we want to talk about the most important concepts of DevOps, we will mention its name in the first step. As we said, DevOps consists of two words: Development and Operation; Therefore, we can say that operation and development are the most important concepts of DevOps.
But these general concepts include several other concepts; For example, in the development phase, we can refer to the plan, code, build and test. In the operation phase, let's mention concepts such as deployment, release, frequent testing and monitoring (Monitor).
The best DevOps tools
DevOps tools are generally responsible for automating processes and checking software performance. In future articles, we will explore the best DevOps tools in detail, but examples include Gradle, Git, Jenkins, Azure, Bamboo, and Docker. To learn more about Docker, you can read the article How to use Docker in an operational environment.
What is Azure DevOps?
One of the most widely used tools in the field of DevOps, project management and cloud computing is Microsoft's Azure software. This tool, having various features and providing a space for high-speed cloud computing, can be a good option for managing software development projects and DevOps.
Who is a DevOps Engineer?
DevOps engineer or DevOps worker is a person who seeks to establish effective communication between operation, development, etc. teams in the organization. DevOps engineer is actually a person who, in addition to mastering the concepts and techniques of this field, is also proficient in the culture required for the successful implementation of DevOps.
What are the benefits of DevOps?
As we mentioned, DevOps has quickly opened its place in organizations around the world, and the number of companies that use this method to improve their performance is increasing day by day; But what is the reason for this welcome? What are the advantages of DevOps that have attracted the attention of company managers?
The following can be considered as some of the most important advantages of DevOps:
Increase productivity through automation
In the words of Robert Stroud: "DevOps is actually empowering the process of transformation in business, which includes making changes in the attitude and performance of people, and also changes trends and culture." The most effective DevOps strategies focus on structural improvements. Setting up DevOps in an organization requires a culture or mindset change.
This new culture causes more collaboration between product, engineering, security, information technology, operations, etc. teams. Also, with the automation of the path, it makes the achievement of business goals smoother.
Optimizing all parts of the business
Patrick Debois, the creator of the DevOps movement, says, "The biggest advantage of DevOps is the insight it creates." This new insight forces organizations to optimize the system as a whole unit and not just optimize the IT department.
In other words, the insight that comes from DevOps helps organizations be more flexible, act data-driven, and move in line with customer needs and business imperatives.
Increasing the speed and stability of software development and deployment
According to statistics, organizations that use the principles of DevOps operate more quickly and stably in the field of software development and deployment. They have also met a key operational requirement; Ensuring that their product or service is available to end users.
An organization that can provide products and facilities to users as soon as possible will have a competitive advantage. DevOps helps the necessary changes to be applied to products more quickly and new features are provided to users quickly.
DevOps teams are agile and add new features to the product in small, targeted chunks. In addition to quick access to new features, DevOps has another important advantage; Possible problems or bugs in this system are identified and fixed faster.
Increased focus on people rather than tools
People are the most important components of DevOps, not tools. They can greatly increase the chances of success of the organization. A persuasive leader can explain the benefits of DevOps agility to business owners and dispel false beliefs and fears.
Also, since automated systems play an important role in the success of DevOps, an automation specialist can develop strategies for continuous software integration and deployment, and ensure that production and pre-production systems are fully software-based, flexible, compatible, and available.
In addition, DuPont provides conditions for experts to be more innovative and creative. The time and resources that were spent on product development and deployment in the past can be spent on innovation.
By setting up the DevOps system, many things are done automatically, and experts can devote more time to identifying the needs of customers and business and reach a deeper understanding of the requirements. All these things will eventually lead to innovation in the production and development of products.
Challenges of DevOps
Despite the various benefits that DevOps brings to the organization and business, this definition also has challenges. The main challenges of DevOps are related to the implementation phase and the use of its various components. Some of these challenges are:
- Challenges of changing the operating environment
- Challenges of team maturity and competence
- The challenge of overcoming outdated solutions
- Regulatory challenges and the overall DevOps process
- CI/CD implementation issues
- Version control challenges in automated testing
- Security challenges
- The challenge of scaling test infrastructure
Income and labor market of DevOps
As we said, devops is a new field that is still going through its growth and maturity stages. For this reason, the Devops job market, especially in Iran, is a market with a clear horizon and a so-called blue ocean for the entry of new and expert personnel.
Having skills along with team work culture is one of the important features to enter the DuPont job market.
According to our reviews of job search sites and annual salary reports, the income of a DevOps engineer in Iran is between 15 and 90 million Tomans (year 1402) according to work history and skills. In the global market, DevOps engineers have good conditions and their average annual income in the US is around $110,000, which is considered one of the high salaries. Europe is also a good choice to enter this field with an average salary of 80,000 euros.
تصورات اشتباه درباره دواپس
Since DuPont is a broad topic and beyond a method or tool, people may have different ideas about it. Some common misconceptions about DevOps are:
- DevOps is a tool.
- DevOps eliminates the operations team.
- DevOps is a defined team with defined routine tasks.
In addition to the above, there are several other misconceptions about DevOps that you can learn more about in the Asa blog article.
Conclusion
In this article, we examined what is meant by Devops and what benefits it has for organizations. We said that this word is made from the combination of the words Development and Operations. From this combination, it is clear that DevOps intends to create cooperation and interaction between the development and operation teams and increase the speed of software development and deployment by automating and optimizing processes.
Finally, DevOps makes products and facilities available to users faster and possible errors can be identified and fixed sooner. The set of these factors will make the path of business growth and development smoother.
