The process of software development has always changed, as talented and creative programmers are always looking for ways to improve the situation. The advent of new languages, libraries, and frameworks shows that the computer world is evolving and that software developers must come up with new and innovative solutions to new problems. We want to see what DevOps means.<\/span><\/span><\/p>\n

What is DevOps?<\/span><\/span><\/h2>\n

DevOps is the word for development and operations, and it somehow combines the two concepts. It creates collaboration and interaction between the product development team and the company’s operations team. DevOps is not a specific language or technology but a combination of philosophy, culture, practices, and tools that help our products or services reach our customers faster.<\/span><\/span><\/p>\n

Development refers to the development team, meaning all those involved in product development, debugging, testing, and ultimately product completion. Operation means IT Operation or operations team. The people who generally maintain the company’s hardware, software, and operating environments. DevOps helps organizations speed up the delivery of their products or services to customers, maintain high-quality work, and have a strong market presence.<\/span><\/span><\/p>\n

Prior to DevOps, development and operations teams operated in two isolated environments. The separation of the two teams’ work schedules delayed the delivery and completion of the project. At that time, without DevOps, most team members spent time designing, testing, and deploying rather than building the actual project.<\/span><\/span><\/p>\n

Agile relationship with DevOps<\/span><\/span><\/h3>\n

Before talking about DevOps, let’s talk a bit about the Agile<\/a> model and its methods. Agile is a fitting name that carries speed and productivity in a project. Some of the popular Agile methods used in software companies are Scrum, XP, AUP, etc. Although each of these methods has its own separate and independent structure, in the end, they grow the collection and improve the quality. In these methods, we are constantly dealing with repetition and getting feedback. Agile helps team members work together to make decisions and move the project forward at high speed and quality.<\/span><\/span><\/p>\n

The main common denominator between DevOps and the Agile method is speed. Both technologies want to shorten the software delivery cycle to the end customer as much as possible. This article is not going to be just about software engineering and its methodologies, so we won’t talk about Agile anymore.<\/span><\/span><\/p>\n

How is DevOps different from traditional software development methods?<\/span><\/span><\/h3>\n

DevOps has made significant changes to product development. It is best to use an example to understand the concept of DevOps, and in this example, examine the difference between traditional methods and DevOps.<\/span><\/span><\/p>\n

Our scenario is that we assume our project is to build an application, and we will review it in two weeks. So far, 80% of the project programming has been done, and we are buying a server to make the project online and transfer the code to the server. We examine this scenario using both traditional and duplication methods:<\/span><\/span><\/p>\n

In the classic way<\/span><\/span><\/h4>\n

The development team activates the new servers, and testing begins on the project. On the other hand, the operations team writes project documentation and examines the required infrastructure. In the DevOps method, after the need for new servers is felt, before the custom team registers, both development and operations units work together on documentation and paperwork to better meet the needs of the project. Then they create new servers.<\/span><\/span><\/p>\n

In the traditional way<\/span><\/span><\/h4>\n

programmers working on a project are better able than anyone else to decide on things like configuring servers, their location, the traffic the program is likely to have, and so on. However, developers usually do not intervene because of the separation of development and operations. In the DevOps method, developers provide their information to the operations team, and they use these inputs to select the server.<\/span><\/span><\/p>\n

In the traditional method<\/span><\/span><\/h4>\n

The operations team does not know the software development process and performs monitoring and review work according to their understanding of the project. With the DevOps method, the operations team is fully aware of the progress of the project and the steps taken. Because development and operations teams interact, they can design a joint oversight plan based on their IT and business needs. Application Performance Monitoring (APM) tools are also used.<\/span><\/span><\/p>\n

Before the program goes online, tests are performed on it to test the program’s performance for the last time. So, the program may crash or crash altogether. In this case, the program’s release is delayed. In the DevOps method, a test is run on the program before the final release, and it slows down a bit. The development team quickly identifies bottlenecks and fixes major problems. There are no problems with the work schedule, and the schedule will be published according to the previous schedule.<\/span><\/span><\/p>\n

The life cycle of DevOps

The DevOps life cycle has five general sections:<\/span><\/span><\/p>\n
