DevOps is a set of principles implemented by development and operations teams to deliver high quality software in record time. In Agile, the development and operations teams worked separately in silos. This had a negative impact on the overall productivity of the organization. DevOps solves problems by bringing development and operations together into teams that work together to achieve common goals. In this article, you'll learn nine key DevOps principles and practices, and how implementing them can help your organization get the most out of DevOps. What is DevOps? DevOps is a software development approach that connects three key components. Development, quality assurance and operation. This is a natural extension of end-to-end accountability, cross-functional components, and agile techniques that facilitate collaboration. The core principles of DevOps are the "ping pong" between development and operations, which facilitates closer collaboration, sets new communication standards, and facilitates smoother integration and automation of daily processes. The aim is to eliminate.
DevOps principles
There are differences between principles and best practices. Best practices are a universal concept and apply everywhere. Consider the most common and generally accepted quality standards applicable to any industry. However, the principle is more product or vision oriented. In this case, the principle applies to the DevOps methodology.
Seven fundamental principles of DevOps:
1. Incremental release
Before DevOps, teams had to wait their turn to implement their code. Delayed code releases often result in bottlenecks or what is called "merger hell". If the developer has to wait a long time to deliver the code, error and incompatibility problems are inevitable.
DevOps advises developers to update their new code as often as possible, usually several times throughout the day. In a DevOps environment, a project is broken down into smaller, more manageable parts and the team submits the code in stages. This makes it easier to troubleshoot the code before releasing it to production. Depending on the workflow, the DevOps team posts daily, weekly or monthly code updates and bug fixes.
The incremental version makes the development and deployment cycle more flexible. As a result, teams can respond quickly to sudden changes and fix bugs and errors instantly. The main goal is to prevent end users from implementing malicious code.
2. Automation
One of the key practices of DevOps is to automate the software development process as much as possible. By automating workflows, developers can focus solely on writing code and developing new features.
Anything that can be automated should be automated in a DevOps environment. For example, instead of wasting time manually checking for code errors, the DevOps team uses a variety of software solutions to automatically build and test programs. It's as easy as running a single command to compile the source code and determine if it works in production. If your application is written in a language that doesn't need to be compiled, the DevOps team can run automated tests to see if the new code is available in production. If there are any bugs or errors in the code, the automation will trigger an alert so that the developer can see which line of code is causing the problem. Automation also plays an important role in managing infrastructure management procedures.
In a
DevOps environment, the team uses Infrastructure as Code (IaC). Infrastructure
automation software like Pulumi helps provide resources and manage
decommissioning. This involves managing the infrastructure as code, rather than
doing everything manually using scripts, APIs and CLI. The goal is to enable
developers to rapidly provision anything from containers and virtual machines
to cloud servers, storage, databases, and other infrastructure.
3. DevOps pipeline
The goal of DevOps is to create a flexible system that is a
framework for continuous development. To do this, the DevOps team designed the
pipeline. Pipeline is a remanufactured system that has a system, which must be
passed code before it can be created. A typical DevOps pipe has four parts:
- Development-- The developer must first write the code.
- Construction-- The team compiled the code on a release to see if there were any problems.
- Buttons.--After the production process, workers perform tests to ensure that the new code is to be used in the production environment.
- deploy-- If the new code exceeds the trial period, it will be passed to the end user.
The DevOps team implements the necessary procedures to ensure continuous code flow throughout the pipeline. The most important are the continuous connection (CI) and continuous transmission (CD), also known as CI / CD. Ongoing integration means developers can transfer and integrate code all the time, continuous distribution means updating code as much as possible.
In this sense, “Anything goes” is the DevOps standard for creating multiple applications and applications. Along with the CI / CD, the team strives to ensure that it continues in all areas of the process (monitoring, feedback and implementation) in the DevOps professional area.
4. Continuous integration
Continuous Integration (CI) plays an important role in the DevOps pipeline. Encourage developers to transfer their code to the central codec several times a day. By connecting small code regularly, you can drastically reduce the risk that malicious code will pass through the channel and break.
Some large organizations running DevOps programs try to create new code hundreds of times a day. Another important aspect of ongoing integration is the automated experiment. Before sending the code to the home directory, the developer takes the task to see if the new code fits the existing code.
If successful, the developer transfers the code to the shared memory. CI depends on the type management system. It is a central code repository that allows teams to detect code changes and manage integration requests.
5. Ongoing delivery
Continuous Delivery (CD) is the launch of regular and timely code updates. CDs rely on developers to manually extract the code rather than on a continuous server that uses an automated process to print the code. For a CD to work properly, it is necessary to create an iterative system that guides your code through the DevOps pipeline.
Manufacturers working around the CD should be aware that code contributions can be made for production at any time. After passing all the tests and exams, you can leave the production code update by clicking just one. Full-time delivery has many benefits. First, code changes are often minor, which reduces the risk of crashes and other performance problems.
Second, the CD makes it easier for entrepreneurs to put in a lot of planning, streamlines the sales process, and then eliminates specific costs in the implementation process. QA teams use automated testing tools such as UFT, Ranorex and Selenium to create code entry tests. If the quality control is weak or poor, it will be sent to the technology. This step involves adjusting to a thorough connection analysis. The form management system allows developers to track changes to a file and share it with other members, regardless of their location. Codes that pass the automated test are merged into a shared memory.
Sending more code increases the connection because it can avoid large differences between the code field and the source code in the future. The most popular plugins are GitLab CI, Jenkins, TeamCity, and Bamboo. The DevOps application allows engineers to bring products such as Puppet, Chef, Google Cloud Deployment Manager, and Azure Resource Manager to the rankings.
6.
Ongoing testing
Ongoing testing is based on the CI / CD concept and promises that your program will be a success. The DevOps team uses a systematic review and process to determine program performance.
The DevOps team reviews news, applications, systems and infrastructure. Once a problem is detected, the DevOps team can restore the application to their previous state.
Meanwhile, the team is working on known issues without the user knowing that the code is updated regularly.
Ongoing surveys also help DevOps team detect problems and compromise performance effectively. After each release process, members should upgrade the CI / CD pipeline to remove obstacles and ensure efficient code transfer from one area to another.
7. State your position
DevOps grows in response. Developers need information from different sources to improve the quality of all their applications. Without a response, members of the DevOps team can take the time to create a product without investing profits with suppliers and customers.
The DevOps team collects feedback from stakeholders, users, and software review technologies before, during, and after the release process.
Collect feedback from various channels, such as social media campaigns, or by interacting with your colleagues. One will review the feedback collected to get the most useful information. Misleading or deceptive ideas can affect the whole development process.
8. Type control
Type management, also known as core management, is at the heart of the successful DevOps project. Help your DevOps team organize, focus, and make team members aware.
Model controls are needed for a computer to be able to support the first set of high-speed applications. Simply put, form management is the central code repository where developers print code and track changes during the development process. Most form management systems allow team members to get out of the original task.
Branch is a copy of the source code of a project that allows any developer to operate without changing the original code. In a typical case, each developer works in different departments of the same project, performing its own testing and code updates. Before attaching the new code to the registry, the program automatically develops the program to ensure that the new code matches the existing code.
If successful, the developer adds new code to the parent directory and executes it when it is created or performs additional tests depending on the operating system. A robust form management system enables DevOps team members to ensure that code-free code is working and used in production.
The future of DevOps
Since the inception of DevOps, its effectiveness has been demonstrated in many ways, from speeding up the development process to adding value and quality products.
DevOps doesn't go anywhere, but it doesn't stop there. Here are three DevOps strategies for the near future: As other businesses move to the cloud, DevOps will integrate with cloud storage and change the way it is created, distributed and used. Experts use BizDevOps, a new software development solution that bridges the gap between developers, team members, and vendors and helps organizations build applications that integrate applications application.
I hope the final point is for the development team to be more involved in the decision-making process to guide the industry in the right direction of digital transformation.
