DevOps is the method of technology that bridges the gap between an organization’s development and operations teams. DevOps helps to create this kind of harmonious coordination through improved communications and cooperation. In this blog, we will talk about the key components that comprise DevOps.
The most critical component of DevOps
Here’s a list of the essential parts of the DevOps Framework that you need to follow to create an efficient DevOps experience.
A Framework for Agile Development
When your Development team looks at the latest trends and ideas, they should be ready to face unexpected tasks based on data that telemetry has accumulated. This could include fixing applications or designs, changing design, altering configurations, or increasing capacity. An Agile Framework, such as Kanban or Scrum, allows you to adjust plans rapidly. If you’re using a framework like Scrum or Kanban, you need to take time out of each Sprint to consider the production variation.
When an arrangement or code modification is essential, testing automation can help the team to see that the change didn’t cause harm to another. In specific situations, it is possible to have several tests running in a complex piece of code. Manual testing could take a long time, so the team can’t move swiftly to solve problems. Automated testing will determine if an issue is resolved in minutes.
How can we ensure that the program isn’t communicating about things specific to the specific environment in which it is running? The answer is to use configuration management as the correct answer. The first step of configuration management is to transfer the design issues from the source code into a document for configuration (e.g., the properties file for Java and the App.config document to use with .NET software). The next step is to determine the configuration file you should use. There are two options for this:
- At the time of running: when the application is starting in its initial phase, the application will determine the environment it is running and load the proper configuration file. Therefore, this method demands the creation of an individual setup file per the environment.
- At the time of Deployment: A second method is to create the configuration file before deployment time. Based on the conditions we’re deploying, deploy scripts will generate the configuration file, incorporating the correct values. Another example of this method could be Octopus Deploy which is depicted in their documentation.
Integration, in this case, is merely to bring your application into a place where it can connect to other components and applications in the ecosystem. Setting a timetable custom to your application’s integration is crucial in achieving a feedback cycle. When our integration process is more precise, so will the feedback process. The main obstacle to slow integration is the manual guides. Therefore, each time we want to improve the efficiency of the cycle, we must automate a procedure or process that was done manually. Some examples of manual advancements that can be automated are:
- Deploying the application: Automated Delivery Pipeline currently assists us with this perspective by requiring creating an automated application that can deliver the deployable object and transmit it.
- Test: We can transfer our application onto Production after it has been thoroughly tested and verified in lower environments. So, when we automatize the number of tests anticipated, we can reduce the time needed for the new code to be distributed for Production. One method to achieve this is to automate end-to-end testing using the Test Pyramid approach.
- Problems with reporting: Instead of sitting at a desk waiting for testers or clients to report problems and issues, we require an automated method of recognizing and possibly figuring them out before our clients notice they are there. Health checks and automatic monitoring and health checks, which we will talk about later, could help in this.
- Troubleshooting The process involves digging into log files, which can be time-consuming when an application runs on multiple computers. This is where log aggregators such as Logstash, Graylog, and Splunk help us speed up the process and make it more efficient because they provide a single location where we can query the logs and find the events.
The Infrastructure Code
This is possibly the most visible aspect of learning DevOps, but I intentionally displayed it towards the conclusion to highlight that it’s not the only thing. Over the years, various excellent practices emerged from creating software for business needs that are widely accepted, yet most of these methods are not applied to infrastructure. If you are not updated with the latest DevOps practices, then DevOps Training will help you learn new concepts. The idea of treating infrastructure as code doesn’t only mean to create code for infrastructure, but as well, it intends to use the above-mentioned best practices for infrastructure code:
- Making it part of a version control system such as Git, Subversion, and Mercurial. This allows us to keep track of changes, understand the reason for changes or revert to the previous version, and the list goes on.
- Appropriately label your scripts and arrange them into folders or packages so we can locate the content efficiently and determine what was created.
- Always look for opportunities to reuse scripts or code and follow the DRY rule (Don’t Reuse Yourself) whenever possible.
- If you can, automate the execution of the hands and eliminate any manual steps as soon as possible. In the first place, documenting and revising scripts is sufficient. Still, sooner or later, we will require the capability to run these scripts simply by clicking a button instead of copying and pasting the chunks of code into an application console to run the scripts. Building tools like Jenkins can be your ideal partner for this task.
- If you can, you can test your code using automated testing. This is the most challenging aspect as we write scripts that contain servers or compartments.
DevOps is about the journey; it is not the ultimate destination. Incorporating all of the practices discussed will allow your projects to adopt an agreement in the course of working. DevOps abilities and tools continue to improve. As with taking advantage of Agile methods, DevOps is a big part of an organization’s overall cultural change pie. The complete solution would include various components such as escalation and on-call procedures, incident tracking systems, and other methods. If you’re trying to create a DevOps process, you must focus on these aspects.
