DevOps Methodology

DevOps (from engl. development and operations; in Russian it is usually said as "девопс") - set the practician, the development specialists aimed at active interaction with information technology service specialists and mutual integration of their workflows each other. Is based on the idea about close interdependence of development and operation of the software and it is aimed at helping the organizations to create and update quicker software products and services.

The dynamic changes happening in the world of technologies impose more strict requirements to the speed of reaction, time of release of releases of IT systems and capability of specialists of a different profile to the modern companies is open to communicate and to cooperate fruitfully. Do not make an exception and developers of the built-in systems. The demanded methodology of continuous delivering solutions shows special conditions to the organization of project processes, and testing stops being the final and isolated stage of all development cycle. However, implementation of testing as continuous parallel to development and maintenance of process generates the mass of questions to practice of such implementation.

Main objective of transition to ideology of DevOps is desire to improve and accelerate customer service. Cost reduction, increase in automation, configuration management improvement, accomplishment of business requests are only satellite tasks. At the same time to different organization types the different structure of commands for effective interaction of Dev and Ops can be required.

With emergence in 2009 of methodology of DevOps which had to respond to the growing quantity of questions to the organization of active, continuous and productive interaction of IT specialists within the project the companies were separated into leaders and lagging behind depending on that, how well they managed to adapt process of testing to the declared principles.

DevOps is rather new concept, and it still has no accurate, commonly accepted determination. In fact, it is set the practician, aimed at active interaction and integration of specialists in development, testing and maintenance. Use of DevOps provides stable, fast and reliable deployment of software including thanks to the continuity of testing that allows to avoid delays and the problems with quality inherent for classical model of project development.

The popularity of methodology considerably increased in recent years. According to RightScale 2016 State of the Cloud Report:[1], acceptance of DevOps increased from 66% in 2015 to 74% in 2016, and among the large organizations adoption of methodology is even higher – 81%.

DevOps implementation – a difficult task for many respondents us the companies: new practice often requires other mentality and fundamental shift in corporate culture. And still advantages which DevOps and Agile promise developers, testers and all command, much more exceed any costs.

  • Developers are involved on projects more effectively
  • Problems come to light at early stages, and costs for their elimination decrease
  • The development cycle and deployments of software accelerates
  • And, above all, the satisfaction of the customer as a result increases

Transformation of a profession of the system administrator under the influence of DevOps

Broad adoption of methodology of DevOps will lead to the fact that from tasks of the system administrator those which are caused by imperfection of computer systems will disappear, need for the routine transactions which are not requiring profound knowledge will disappear and on this background qualification requirements will raise [1] (in more detail).

DevOps command topology

What structure or topology of the DevOps command is suitable for the organization, depends on many questions, for example:

  • What set of the released and supported products – the are less than products, the interrelation of Dev and Ops is more.
  • Degree, force and efficiency of a technical guidance - whether has Dev and Ops a common goal.
  • Whether the organization is ready for transformation of a role of IT of operation from "bring-give" in built in business process.
  • Whether there are in the organization leaders who are ready to point to problem areas and to accompany changes.
  • Most often creation of "dream team" will demand consecutive change of several models.

Main trends

2020: 10 forecasts for developers and DevOps for 2020

At the end of February, 2020 IDC published forecasts for developers and DevOps. Analysts placed emphasis in the Chinese market and also practical recommendations on 2020 and the next years. Authors of a research consider that their work provides the comprehensive analysis of trends of the market of developers and DevOps.

1. Optimization of AI for developers

According to expectations of IDC, by 2024 56% of the companies will not limit use of AI and machine learning to application development - they will be applied in design, quality management, security and deployment of new technologies. By 2023 70% of the companies will invest means in retraining and training of employees, including in third-party services, for acquisition of new skills and acquaintance to new methods of work.

Many companies use DevOps methodology for acceleration of release of applications

2. Wide use of container platforms

By 2024 70% of new applications will be developed on container platforms for fall forward of deployment, coordination and portability of applications.

3. Growth of a share of non-staff developers

By 2023 the number of the developers occupied part-time (including business analysts, analysis and data processing specialists and also researchers of data) in China, will become twice more. In particular, the number of the developers occupied part-time will increase from 1.8 million in 2019 to 3.6 million.

4. DevOps as daily activity

By 2023 the number of the organizations issuing codes for specific applications will increase from 3% to 30%. By 2024 at least 90% of new versions of applications of the corporate level will have the built-in functions of AI, though will make only 10% of all market.

5. Acceleration of transformation of traditional applications

By 2022 the accelerated upgrade of traditional applications and development of new applications will lead to increase in a share of cloud applicaions up to 25% that is caused by use of microservices, containers and the dynamic orchestration.

6. DevOps to focus on business key performance indicators

By 2023 40% of the DevOps commands will invest means in expansion of tools and will focus on key performance indicators of business, such as costs and income as transactions will begin to play more important role in performance of complex applications and a business impact.

7. Use of the corresponding analytical tools on the basis of software open source

The growing dependence of applications on components open source provided rapid growth of analytical tools. By 2023 tools of the analysis of program components which by February, 2020 are used only by the separate organizations will be used by 45% of firms.

8. The companies create own ecosystems of development

By 2023 60% of the Chinese companies will create own program ecosystems, and 50% will get access to key reusable components of the code from public libraries.

9. Growth of code bases of open access

By 2024 the share of the open source software, received from the relevant libraries, will double, i.e. up to 25%, and other 75% will be configured according to business models of the organizations or scenarios of use.

When implementing these strategy there is an opportunity to use self-service resources thanks to which the methodology of DevOps allows to execute development and testing in a cloud

10. Recognized applicability of DevOps

By 2024 less than 35% will fall on applications which are completely used by DevOps. The enterprises are recognized that not all applications can benefit by the difficult transactions covering development and production and connected with continuous integration and continuous delivery.[2]

2019: The main trends in DevOps for 2020 from Forrester

At the end of November, 2019 the Forrester analytical company published a research in which listed top trends which should be expected in the field of DevOps in 2020.

End of strategy of Plan, Build, Run

Long time control of development of IT solutions was exercised by means of an operational model under the name Plan, Build, Run (planning, creation, operation). Its main problem consisted in insufficient flexibility. In the new digital world breaks between development and applications launch when experts should carry out quality check are inadmissible.

Forrester published a research in which listed top trends which should be expected in the field of DevOps in 2020

According to experts, will refuse this model of the company, including the step-by-step structured process with decision making upon completion of each stage.

The continuous management of corporate IT based on rules, dynamic control and automation

The main attention in 2020 will be paid to the guidelines, and more and more companies will use self-correcting dynamic controls. The automated platforms will submit substantially to management: sample samples and Wednesdays which specialists in start of products use will pass to automatic control taking into account deviations from observance of policy.

Unstructured organizational models

Forrester considers that the heads who are responsible in the company for management of corporate information technologies will stimulate developers to give and keep the promise at project implementation, but at the same time they will give them big freedom in how to do it. The main issue will be not "How to manage?", and "Than?", researchers predict.

Psychological security

Following in the footsteps of Google, leading companies will begin to measure psychological security as a key performance indicator. I will not be surprised if risk managers do note the low level of psychological security as serious organizational risk! In the same way as we foretold that chaotic development will become the recognized strategy of management whether the organizations will implement adequate measures concerning an organization culture? — one of analysts of Forrester reported.

Forrester predicts that in 2020 the tools measuring performance and value of development teams in real time will be widely used

Emphasis on efficiency of development

Forrester predicts that in 2020 the tools measuring performance and value of development teams in real time will be widely used. At the same time developers will pay special attention to such indicator as customer satisfaction.

Passing to DevOps, business gets several advantages. Among them:

fast entry into the market (for example, reduction of time of a cycle and higher rates of deployment); quality improvement (for example, increase in availability, is less than failures, etc.); increase in organizational effectiveness (for example, more time is spent on the activity connected with increase in value of a product in comparison with losses, increase in amount of the functionality transferred to the customer).

Training

Analysts of Forrester also consider that sets of work benches of application development DevOps will include even more often the built-in training aids to allow developers to purchase constantly new skills. It is connected with the fact that traditional learning tools, such as books, online training, video and offline - rates, are remote from tools which in reality are used by developers. Implementation of educational components building tools should accelerate programming process.[3]
