A group of tools and technology known as DevOps (development and operations) are used to execute various business activities. It tries to close the gap between the development department and the operations department, two of the most important departments in any IT firm. You may learn more about the many ideas that are crucial in defining DevOps from this article.
History of DevOps
The Development team and the Operations team were two distinct IT teams in a business before DevOps gained popularity.The software’s development team worked on it, creating it, and ensuring sure the code was error-free. The team publishes a code that must be run by the Operations team, which is in charge of the code’s release and operation, after many long hours of labor and much trial and error.The operations team will evaluate the application’s functionality and performance and, if any defects are found, report them.
Even though it seemed straightforward and well-planned, there was always a struggle when it comes to implementation between the two main teams.For example, let’s assume the operations team executed the identical code using an i5 processor, 16GB RAM, OS called Centos, and PHP 7.0 programming language, but the development team produced it using an i7 processor, 8GB RAM, OS called Ubuntu, and PHP 5.6 scripting language.The identical code wouldn’t run when the operations team tried it.The variation in the system environment or any missing software library might be the cause of this.
Even though the issue could be in their own system, the operations team marked this code as flawed. As a result, there was a lot of back and forth between the Operations team and the Developers.DevOps was created as a result of collaboration between the Operations (‘Ops’) and Development (‘Dev’) teams.For instance, the development team’s code was contained in a container, a lightweight software environment, to address the aforementioned issue.This software environment contained every piece of necessary software that the code or application would need to function properly.
When the developers were through, they would simply give the operations team this container and the code. This container will be executed by operations together with the code, and everything went as planned!
What is DevOps?
The phrase “Dev-Ops” refers to the practice or approach of employing various technologies to resolve conflicts between developers and the operations team. DevOps is neither a team nor a tool.
The operations team’s insistence that the development team finishes outdated, unfinished projects put constant pressure on them to do so. The time it takes to deploy and test the code is eliminated using DevOps. As a result, the developer receives immediate feedback on the code, which enables them to quickly fix errors and get the code ready for production.
The life-cycle of DevOps
DevOps has seen several steps to get to where it is now.
Continuous development, testing, integration, deployment, and monitoring are all parts of the process. Here, we use an example to further example.Instagram is a popular program that people use all around the world. A large crew is working continuously behind the scenes to develop, test, and add features to it so that it can function as it does.The code for the application is planned and created by the developer, tested using test suites, and then submitted to production if the tests pass.
The monitoring tool maintains a track of defects and user feature requests in the production environment. For instance, Instagram has launched features like IGTV and Instagram Stories that weren’t previously included in the Instagram app.The program also included a glitch that caused the feed to be displayed sideways, driving everyone insane. Although this has been patched, how do you suppose developers learn about bugs like this?
These issues and feature requests are kept under constant observation. Developers get the input, make the necessary modifications, and re-push the code as part of the DevOps Lifecycle.As a result, the given example shows that the program is always being worked on and developed.
DevOps Lifecycle refers to the process of continually improving the application by introducing new features and addressing defects in the smallest amount of time.
Continuous Development
The programmer creates the code from scratch, uploads it to a version control system like Git, and then designs and develops it. There are comments that the developer has to include in the program even after the final release. Therefore, continuous development refers to the developer’s ongoing activity of developing the application.
Continuous Testing
The code is tested using test codes when it is submitted to the source code site. Before being sent to production, the source code is continuously tested after each modification is made.
Continuous Integration
The application code must proceed to the following step of the DevOps lifecycle after the previous one is complete. With the use of integration tools, this occurs. Continuous integration is the term used to describe the process of continually using tools to harmonize the code from one stage to the next.
Continuous Deployment
The application environment may need to be modified for each new feature added to the program. Configuration management is the term used for this. We employ numerous deployment technologies to do this. Continuous Deployment is the method of modifying the application environment continually based on the inclusion of new features.
Continuous Monitoring
Even after careful planning and testing, problems may still enter the production process. The monitoring tool regularly checks as and when the program receives updates in order to keep track of these issues, any other improper system behavior, or even feature requests.
Using task management software, you may keep tabs on the progress of certain tasks as well as how things are being created.Numerous tools that support the efficient operation of DevOps are used in every effectivestage.
Here are a few significant examples:
Git
Given that it is one of the most well-liked free, open-source version control systems and can manage projects of all sizes, it is a DevOps tool that is often used in the software industry. Git enables us to monitor the development of the work. We have the option to save each version of the source code and go back to a previous one as needed. Git is crucial to the ongoing growth of the DevOps life cycle.
Docker
The docker is an additional useful tool. Docker automates the deployment of the programs and uses ‘containers’ to enable distributed development. Docker separates the apps into several containers to make the program more portable and secure. The Docker applications work on any OS or platform.
Selenium
This is a lightweight framework for web application software testing. It is an open-source program that functions on a variety of operating systems, including Java, Python, Ruby, Perl, PHP, JavaScript, etc. Continuous testing is carried out using Selenium.
Maven
Maven is one of the top DevOps tools that offers us principles that, when followed, allow us to do our work more quickly and with fewer setups, from project structure to building stages. The source code is compiled, tests are run, the results are packaged into JARs, WARs, etc., and the packages are uploaded to remote repositories.
Jenkins
It is a testing-capable continuous integration server. It aids in identifying and eliminating errors in the code as a developer. As a result of Jenkins’ extensive plugin ecosystem, which has around 1000 plugins, it can interface with practically any DevOps technology.
Nagios
This is an additional tool with a robust plugin system and free and open-source monitoring tools that assist in identifying and resolving IT infrastructure issues before they have an impact on delicate business tasks.
Ansible
It is yet another open-source solution for managing and deploying IT configurations. It makes use of a straightforward YAML syntax. The host system where the automation is to be performed does not need any additional ports installed to use Ansible. This helps the application conserve a lot of resources. The modules may be expanded with any programming language and support JSON. Overall, this is a straightforward tool that boosts productivity significantly.
Puppet
It is a framework for configuration management that enables the administration of the infrastructure as code. Code delivery is quicker and more secure since infrastructure management is automated. For smaller projects, Puppet also offers open-source tools.
DevOps is made possible by the many phases and tools.
