How to understand the nature of DevOps and the current situation and trend of the industry, I believe that many inexperienced people do not know what to do about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Compile manually, upload server files, execute various commands, start and stop the server, find a BUG, and repeat the steps mentioned before. Today, it seems that the ironic repetition of work is done by IT personnel by hand before the concept of DevOps.

Not only that, the concept of DevOps was first put forward because of the pain of traditional mode operation and maintenance. As we all know, the word DevOps comes from the combination of Development and Operations. As the meaning of the word, DevOps is to make software developers and operation and maintenance personnel better communication and cooperation, through the automation process to make software construction, testing, release more fast, frequent and reliable.

According to the RightScale2018 annual cloud computing survey, the overall adoption rate of DevOps has increased from 74% to 78%, while the DevOps adoption rate of enterprises has reached 84%. 30 per cent of companies are adopting DevOps company-wide, up 9 per cent from a year earlier.

The improvement of these figures not only represents the consensus that DevOps can bring practical results, but also confirms that DevOps has been valued by more and more enterprises in the past two years. The concept of DevOps is deeply rooted in the hearts of the people, which is inseparable from the mature development of cloud computing, container / Docker, micro-services, agile and other related concepts and implementation. The essence behind it is the lean operation of enterprise IT in order to face faster business trial and error and business innovation.

Although the concept is good, landing is difficult?

One of the great benefits of DevOps is that it can be delivered efficiently. The concept of DevOps points to "a high degree of automation", trying to develop an assembly line from development to automatic operation, so as to get rid of the shackles of labor to the maximum extent and achieve the upgrading of enterprise productivity.

For example, continuous integration and development can realize the integrated automatic process from development testing to online operation and maintenance; intelligent early warning helps users to automatically monitor the running status of the cluster and quickly locate the specific location of the problem. timely notify users to quickly solve the problem and so on.

Another benefit of DevOps is that it will improve the organizational culture of the company and increase the sense of participation of employees. Employees become more efficient, satisfied and fulfilling.

Thus it can be seen that if DevOps can be adopted, the company can do more innovation, shorten the development cycle, bring products to market more quickly, and at the same time create differentiated business and value, improve organizational efficiency, instead of constantly fixing old problems.

Although DevOps has many advantages, the future is bright, and the enterprise's evaluation of DevOps is also very high, the actual situation is that there are many people who say it, but little has been done.

The reason is that DevOps does not simply merge the development department and the operation and maintenance department, but also changes the corporate culture and organizational structure, and strengthens the cooperation and communication between the development department and the operation and maintenance department through automated infrastructure, reasonable process specification and intelligent automatic operation system testing.

First of all, it involves the issue of ideas. The ultimate goal of DevOps is to strengthen the cooperation and communication between the development department and the operation and maintenance department, how to reverse the current culture to the DevOps mode of thinking, and find a consensus between the development and operation and maintenance departments?

For traditional enterprises, especially large distributed organizations, DevOps success in the overall sense is often impossible to achieve. Because DevOps requires deep cultural and organizational change, there is too much to change. This means that people have to throw away the obvious and hidden rules that have been pursued for decades. You have to tell your old subordinates that most of what they know and do every day is out of date.

Second, if you want to reshape a team for DevOps and application flexibility, you need to have the courage to break down IT grouping barriers and make tough decisions on team member selection.

There are many difficulties, how to achieve it?

There is no doubt that DevOps is very valuable to the organization, but it is important to note that the entire company needs to be involved in DevOps to succeed. DevOps needs the support of senior leadership and the participation of everyone involved in the final product, not just the development and operations departments.

First, find a consensus between developers and operators, which requires strong leadership to achieve change. Of course, it also takes time and money, and requires difficult decisions in the selection of team members.

You can start small and don't expect everyone to be convinced of DevOps in the first place. In practice, winning support in a small organization for a particular project wins ambassadors who will help promote DevOps elsewhere in the company, which has a multiplier effect.

Second, organize work around business systems rather than responsibilities, which is the moral of DevOps breaking down IT grouping barriers. A team should have developers to create code, from the user interface to business logic and data structures, as well as operators responsible for operational automation and deployment. Teams stay together and share responsibility for their applications and systems.

Of course, in order to promote the DevOps strategy, it is necessary to adjust the assessment and incentive mechanism. The overall team created and operated by the system should be rewarded, and the award should be determined according to all the elements of team work.

Third, the team needs to choose the most appropriate tool. Although DevOps is a concept, tools are an important part of implementing DevOps. In recent years, the booming CORNERSTONE is one of the most suitable tools to implement DevOps.

Without understanding the DevOps life cycle, the understanding of DevOps will be one-sided. Let's take the CORNERSTOENE one-stop cloud DevOps platform as an example. Let's explore the lifecycle of DevOps.

1. Continuous development:

This is the stage of continuous software development in the DevOps life cycle. Different from the waterfall model, software deliverables are decomposed into multiple task nodes with a short development cycle, which are developed and delivered in a very short time.

In the CORNERSTONE task module, it will be the responsibility of whoever the task is assigned to. And the task supports multiple responsible people associated with sub-tasks, and all tasks and states will be reflected in the task module. The participants in this task process know the status of the task and the problems encountered at any time, which can effectively promote the solution of the work. With CORNERSTONE, we can help us trace and monitor, promote effective responsibility for people who take on tasks, and be able to synchronize information in a timely manner.

2. Continuous testing:

At this stage, the developed software will be continuously tested for bug. The CORNERSTONE platform covers the complete testing process, which can write test cases, establish a use case base, reduce repetitive operations, and make the cooperation of the R & D team more efficient and the product delivery faster. The two commonly used functions are:

1) Test case management

By writing test examples, making test plans and implementing them, the test results can be directly related to defects, which is convenient to track and deal with the problems, and realize the whole process control of iterative quality.

2) defect management

Powerful defect management and statistics function, through grouping, solving status, priority and other lists to record and track defects, at the same time identify the person responsible for defects, timely follow-up to solve defects; at the same time, support import and export functions, export support for any format, not restricted by the template.

3. Continuous integration:

This is the stage when code that supports new features is integrated with existing code. Due to the continuous development of the software, the updated code needs to be constantly integrated and smoothly integrated with the system to reflect changes in the requirements of the end user. The changed code should also ensure that there are no errors in the runtime environment, allowing us to test the change and check how it reacts with other changes.

CORNERSTONE maintains that the results of continuous integration are deployed to the corresponding test environment, and all deployed versions can be accessed at any time in the test environment, and released to the production environment in grayscale.

IV. Continuous deployment:

It is the phase of deploying code to a production environment. Here, we ensure that the code is deployed correctly on all servers. If any features are added or new features are introduced, you should be prepared for more site traffic. Therefore, the system operation and maintenance staff have the responsibility to expand the server to accommodate more users.

CORNERSTONE supports DevOps implemented by script pipeline, supports continuous integration and automatic deployment, can operate directly on a visual server, and satisfies multiple development languages at the same time, completely solves the bottleneck of agile development at the operation and maintenance level, and facilitates developers to manage the project development life cycle as a whole.

5. Continuous monitoring:

This is a critical stage in the DevOps life cycle, which aims to improve the quality of software by monitoring the performance of the software. This practice involves the participation of the operations team, who will monitor user activities for errors / system irregularities. This can also be achieved by using a dedicated monitoring tool that will continuously monitor application performance and highlight problems.

CORNERSTONE embeds the integrated operation and maintenance platform to realize the digitization and standardization of IT environment, which is the basis of direct operation and maintenance analysis, reduces manual intervention and reduces labor costs.

Finally, a good tool must be controlled by an able person in order to exert its power. Even if you find a useful tool, you still need IT personnel who are familiar with the tool chain and have the appropriate skills to provide technical support to accomplish the mission of automation.

Generally speaking, DevOps, as a concept, promotes cooperation between developers and operators, and effectively responds to current business needs. Its realization is the superposition of new ideas, new tools and new skills. Although there are still all kinds of problems in implementation, DevOps is the trend of the times. As the senior level of the enterprise and the staff of development, operation and maintenance, we can't turn a blind eye to such changes.
