What is DevOps?
The DevOps methodology improves communication between your developers and project operations. The goals of DevOps are
- Save time resolving incidents
- Start new functions faster
- Reduce risk through process automation
- Significantly escalates the satisfaction of your customers and developers at the same time.
We do this by talking about a feedback loop. It’s a DevOps concept that relies on measuring development impact to learn and learn more about its effectiveness.
According to IDC, 20% of application development projects today benefit from a DevOps approach. That number will drop to 35-40% by 2021. It’s no accident that so many IT teams are embracing the DevOps methodology for the project.
DevOps Principles
Using DevOps methodology on your software development team will dramatically change your business. This will change the way your development team codes and releases versions. It is simply based on 6 basic principles:
- Automation
- Repetition
- Self-service
- Continuous improvement
- Continuous test
- Collaboration
Automation allows developers and companies to simplify the process and help teams become more productive. Automation reduces the number of manual actions. It improves development quality and software security. While the iteration speeds up the development process through faster feedback from end-users. Self-service also speeds up releases, allowing developers to automatically deploy applications when needed. Continuous improvement should make the process smoother. Part of the DevOps process is doing an autopsy after each incident.
An autopsy records each incident, its impact, the steps to resolve it, the cause of the problem, and the steps that were taken to prevent it from happening again. Continuous testing allows for faster launches and, at the same time, better quality. And last but not least, a collaboration between developers and operations is essential for pooling efforts and achieving success faster.
The DevOps Process
The DevOps process consists of several steps and the steps are:
Plan:
This is the part of the project where you organize tasks, create schedules, and set up your project management tools. The idea is to plan the tasks using the agile methodology user story process. Writing tickets in the form of a user story allows developers and operations to understand what development needs to be done and why. A perfect user story such as what (who, where, trigger), why, and acceptance criteria. (Example: as a user, I open a popup in my customer account when I click on “Option” and I can change my last name and first name).
Code:
This is where developers do development and code review. When the code is done, they merge it. In DevOps practice, it’s important to share a code tool between operations teams and developers like Github or Gitlab.
Build:
This is the first step towards automation. The objective is to create, compile and test the source code in the desired format and make it available at a specific point in the infrastructure. Once this step is configured, the Continuous Integration (CI) and Delivery (CD) tools can verify and verify and generate source control source code.
Testing:
The continuous testing process reduces risk. Automated testing ensures that no errors are implemented in production. You should implement testing tools in your workflow to ensure the best quality development for your software.
Release:
The code has passed the testing process (continuous integration) and is ready to be deployed.
Deploy:
The operations team makes the new functionality available in production. However, since automation is part of the basics of DevOps, it is possible to set up continuous deployment.
Operate/configure infrastructure:
Operations Builder maintains a scalable infrastructure, infrastructure as code, and checks for security and protocol management issues.
Monitor:
Monitoring is an important step as it helps you resolve incidents faster and create a better end-user experience.
Because DevOps aims to significantly increase your customer satisfaction, your teams naturally start with a new feature for your software or application. That’s why we’ve always designed DevOps as an infinite loop.
Implementing DevOps on your team
If your team hasn’t yet implemented a DevOps or even an Agile process, this can seem confusing, especially as it means not only a change in the organization but also a change in your team’s culture.
To introduce your team to DevOps, you need to take your time, and go step-by-step, and take your time. To gradually implement the new culture and organization:
- Start by changing the way your teams think. The DevOps process cannot exist without tools, but it’s not enough, developers and ops need to understand each other’s work and take care of it. In short, developers and operators need to learn to work together.
- Implement an agile development process. Most DevOps projects use Agile Scrum or Kanban methods.
- To carry out the fourth step, it is necessary to introduce cloud computing (private, public, or hybrid cloud).
- Automate the delivery of your software with Continuous Integration (CI) so developers can easily drive new features.
- Use continuous software testing to reduce risk.
- Implement continuous deployment (CD), there are fewer manual actions, and you can deploy new versions to production faster. For more details visit DevOps Training in Pune
Remember that adding these processes changes your organization and creates new requirements. For example, your team may need training on new DevOps tools that have been implemented.
