What is DevOps?

DevOps is a software engineering practice that aims to unify software development (Dev) and operation (Ops). Its main function is the automation and monitoring of all phases of the construction of enterprise or open source software, in order to ensure greater productivity, integration between teams and expand the accessibility of environments.

DevOps does not currently have an authoritative definition. We can say that DevOps emphasises how efficient organisation teams can manage software lifecycle management through automated tool collaboration and communication to deliver more stable software faster and more frequently.
In addition, it assists in managing the release of new versions by standardising the development environment, which results in faster and safer production of applications and services. As a result, development cycles are shorter, deployment frequency is higher and releases of new versions become more secure.

How the process works

Because it is a working model, DevOps makes use of a toolkit. They may fit into one or more of the categories in the development and delivery process. They are: coding, compilation, testing, release, deploy, configuration, monitoring and planning.

How DevOps Works?

There are a number of ways DevOps can work for your advantage by adopting a team-integrated solution through best practice and greater productivity.

Collaboration: Because of their collaboration-based model, teams tend to increase responsibility sharing and combine their workflows. This leads to time savings and increased efficiency.

Security: Automated compliance policies, controls, and configuration management techniques enable rapid operation while preserving and controlling code versioning.

Speed: Adopting DevOps practices enables configuration and performance management with real-time monitoring. Automating routine tasks to increase the frequency and pace of launches enables software innovation and improvement.

Scale: The methodology provides the ability to operate and manage infrastructure and development processes at scale. With automation and constancy, you can manage complex or dynamic systems with reduced risk and efficiency.

DevOps is an operational and development engineer involved in the lifecycle of the entire service from design to development and product support. DevOps is characterised by the same tools used by operations engineers and development engineers, from source control to testing, covering the entire agile development process.

DevOps is an extension of the agile principle that extends boundaries from “code” to the entire delivery service.

The origin of DevOps comes from the increasing need for innovation in system technology. The DevOps movement inherits from the Agile Systems Management Campaign and Enterprise Systems Management (ESM) campaigns.

Some people think that DevOps means that developers take over operations. This is only part of it, not all. When we realise that some operations need to be automated, the operations staff needs to do some automation development, the developers also write “operation and maintenance” code, or both. The scary thing is that there is no overall way of collaborating between the two people. All successful teams work together to develop deeper development skills and deep operational skills to create a better product.

DevOps process works in three ways. Here are the three basic modes and features.

  1. System level efficiency considerations

    This emphasises the efficiency and performance considerations of the entire system, rather than being considered in isolation from the work department or subsystem. It can be a large perspective for integrating developers and IT operations staff or it can be as small as independent publishers, such as developers and System administrator.

    The focus is on the entire business value chain, starting with the identification of business needs, the development and construction of developers and then delivery to IT operations – in the final stage, the software value of the customer as a service.

    If you want to improve the value of the entire system, you must thoroughly understand whole system. Due to the emphasis on overall performance, you can’t push the defects to the downstream or allow the overall degradation due to local optimization.
  2. Amplify the feedback loop

    It’s about creating a feedback loop from right to left. This feedback loop can be continually corrected if necessary, shortened and amplified. Being able to understand and respond to all customers including internal and external, shorten and amplify all feedback loops and embed the knowledge we need.
  3. Continuous exercise and learning

    This approach is to create a corporate culture that fosters two things: experimenting with adventures and learning from failures.

    Recognising that repetition and practice are prerequisites for mastery.
    Experiments and adventures ensure that we continue to drive improvements, even if it means getting into dangerous areas beyond our control, we must have the skills to help us get out of danger. 
    The results of the third road include the allocation of time to improve daily work, creating rituals for adventure, rewarding teams, and introducing errors into the system to increase flexibility.

Recommendations for DevOps Practice

For a DevOps culture to build on your business, there are some recommended guidelines. Here are some of them:

Engaged People:

Attitudes that promote integration and develop empathy for teamwork are important recommendations for implementing a culture that unites infrastructure, development and operation.

Focus on the project:

Teams must be collaborative and mutually respectful. With a common goal for the project, prioritising it and not its areas of expertise.

Collaborative work dynamics:

Instead of isolated meetings, it is advisable to promote the integration of professionals from all sectors. This provides an understanding of the goals to be achieved in alignment between the different teams.

Agile Principles:

Agile methodologies provide fast and continuous deliverables for software development. Through them, optimise management time and profitability.

Continuous Integration:

Tools should drive the entire process involved in delivering new software versions. This includes creating environments, deploying code with infra configurations, automated testing, rollback, and auditing.

Organisational structure, corporate culture and ideas need to be designed from the top down to promote communication, collaboration and integration between the development department, the operation department, the maintenance department and the quality assurance department. In simple terms, the organisational form is similar to the system layered design.

Automation means that all operations do not require manual participation, and all rely on the system to automate. DevOps emerged as the software industry became increasingly aware that the development and operations departments must work closely together to deliver software products and services on time.

Conclusion

In order to seize business opportunities, business needs to be iterated quickly and continuously error-tested. Therefore, enterprises need to rely on the ability to have continuous delivery, including not only technical requirements but also product requirements, how to have continuous delivery capabilities, and large and comprehensive architecture. Because of inefficiency, it is obviously inappropriate. Therefore, the micro-service architecture evolved to meet the demand. The effective implementation of DevOps depends on a certain ground, i.e. agile infrastructure services. In reality, only the cloud computing model can meet the overall requirements.
