This article mainly introduces "what are the changes brought about by the migration from Ops to DevOps". In the daily operation, I believe that many people have doubts about the changes caused by the migration from Ops to DevOps. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the doubts about "what are the changes caused by the migration from Ops to DevOps?" Next, please follow the editor to study!

What is DevOps?

DevOps is a set of practices that encourage agile thinking to improve the speed and quality of the software delivery process. In previous approaches, such as waterfalls, development and operations teams were considered separate, with each team having its own given task and responsible for only part of the delivery process. Through this model, development and operations teams are seen as interdependent and working closely together throughout the software application lifecycle.

Before DevOps, the traditional model involved a defined set of phase flows, in which the output of one phase was the input of the next step. This makes all phases interdependent, making it longer and more expensive to deliver new features and fix bugs.

The key elements of DevOps are collaboration, automation, continuous integration, continuous delivery, testing, and monitoring.

Benefits of DevOps

One of the biggest advantages of DevOps is that it provides a fast feedback loop. This enables enterprises to quickly identify errors and understand customer needs. It also enables them to release features very quickly. In addition, it leads to higher efficiency and better software.

Another benefit of DevOps is that it delivers higher quality products and fewer failures. One of the key methods to determine software quality is the number of defects in the software. The adoption of DevOps and Agile methods has had a huge positive impact, improving the quality of the development process by 41 per cent. Of course, the collaboration between the development team and the operations team has a lot to do with improving product quality.

Adopting DevOps can contribute to a stable and balanced work environment. Releasing the tension and pressure of time can destabilize the team and reduce their productivity.

Automated repetitive tasks leave more room for innovation for the team. In addition, automation and monitoring can be implemented at every stage of the software development process. From integration, testing and release to deployment and infrastructure management.

If done correctly, DevOps can help reduce production and non-production costs. It can reduce maintenance, personnel, quality costs, etc., and make the company work faster and make higher profits.

How is DevOps different from traditional Ops?

When the development team and the operations team are separate (as is the case in traditional operations), each team takes care of part of the delivery-the developer develops and then operates. In other words, the goal of IT Ops is to ensure that everything works properly in production. They ensure that resources are available and run at optimal performance. They provide a reliable and optimized infrastructure, which means ensuring that there are as few changes as possible to ensure it.

Instead, DevOps encourages these teams to stick together, understand each other's tasks and concerns, and stay overall. They also spend less time managing support because of higher levels of automation and self-service tools. With this extra time, the team can focus on infrastructure improvement, innovation, and self-improvement.

Mentality switch

The first step in migrating from IT Ops to DevOps is to understand that you can control the entire delivery process. IT Ops is responsible for ensuring the stability and reliability of the system, ensuring fewer changes, fewer variables, and end-user processes in place.

But in DevOps, this way of thinking doesn't work. Engineers are now the steering wheel of the organization. They build automation, improve application delivery, find new ways to ensure security, and are satisfied with failures and errors.

In DevOps, decision making is closer to the actual work team.

infrastructure

Infrastructure settings used to be scripts that could automate parts of the process but needed to be triggered manually. This took a lot of time to complete, and produced a lot of mistakes that could have been avoided.

In DevOps, ops's work goes far beyond scripting. It's actually coding-the infrastructure itself has become code. Build and configure cloud infrastructure through code. This is a shift from "server thinking" to "service thinking" for most developers. Infrastructure, or code, enables you to define the appearance of infrastructure components. Component is bundled with logic about how to configure it. You need to define a pipeline for the steps that the component is ready for deployment.

To be an infrastructure coder, not an infrastructure administrator, you need to think about workloads and services rather than servers.

Automation is the key.

In traditional IT practice, the automation part is about creating consistency and recording everything and reducing variables. Documentation is essential, but it must not slow down automation, and what's worse, it can be an excuse for not being automated.

Manual work and repetitive tasks are always error-prone. Do the same configuration over and over again, otherwise it may become uninteresting and inefficient.

Automation is part of every phase of the development cycle. From code submission to build trigger, execution of unit tests, packaging, deployment to the environment, verification, smoke, acceptance testing, and finally deployment to production.

Automating infrastructure settings, configuring the environment, and deploying software are the main advantages of DevOps. This helps deliver functionality from code to production within hours and get faster product feedback.

Failure and error

DevOps follows the concept of Fail Early. In a traditional IT environment, failure is not an option. You do anything to avoid the risk of loss: introduce meetings, procedures, approvals …

In DevOps, failure is part of the game. This is inevitable. If your failure is small and occurs prematurely, you can control the failure so that you can recover quickly. The discussion of failure is very important because it is an opportunity to learn. Where something goes wrong is more important than doing the right thing. DevOps is a culture beyond reproach. DevOps practices support this culture, starting with test-driven development, small batch deployment, and automation.

Increased visibility

Traditional IT companies have processes and limitations in seeing who sees the content. Having the right to carry out surveillance is considered a great responsibility. In DevOps, everyone must have access and visibility to the software. This helps developers stay ahead of problems and better detect and solve problems. Application logging should be used in conjunction with environment logging so that developers can understand how applications work in different environments. Access monitoring helps the team identify the point of failure and improve automation and software quality.

Tools

The best ally of DevOps is the tool that brings efficiency. Throughout the software delivery cycle, you need multiple components to automate:

Collaborative tools such as communication, chat and knowledge sharing

Build tools: source code management, continuous integration, database management

Testing tools: unit testing, automated testing.

Deployment tools: configuration management, artifact management, orchestration and scheduling

Monitoring tools: logging

It may be difficult to learn all these different tools themselves, but you also need to make sure that the tools you choose are compatible.

Automation tools are designed to support release speed and application quality. They will help you quickly and easily restore any unwanted changes. If changes occur outside the code, the tool restores the changes and keeps the server in a stable state.

Introduction

DevOps does not have a simple guide. You should definitely start by improving communication and collaboration between development and operations teams. This will help them better understand their needs and each other's tasks so that they can achieve a common goal together. Ops engineers already have the ability to use tools to build automation and support environments. They need to change their way of thinking and focus on sustainable development.

Start small, and then gradually expand the scale. It is always safe to integrate DevOps culture into a small team and observe its achievements. Learn to adjust and adjust the structure and methods of the company from this process. This is how you find the right balance for your particular business.

At this point, the study on "what are the changes brought about by the migration from Ops to DevOps" is over. I hope to be able to solve your doubts.
