The word DevOps speaks for itself: it is a combination of ‘development’ and ‘operation’. The DevOps lifecycle manages the relationship between the development team and the operations team to deploy the right product to the customer faster using automation tools.
DevOps increases the organisation’s speed to deploy its product faster and deliver it accurately to the customer. This helps the organization to provide better services and compete with others in the market.

Let’s discuss the DevOps lifecycle to understand exactly how it performs all the tasks. Below is a diagram that shows the structure of the DevOps lifecycle.
The first step in this DevOps lifecycle is coding. In this step, developers write code on any platform to develop the product for the client.
The second step is to build the basic version of the product using a suitable programming language.
The third step of testing, in which the assembled products are tested using test automation tools like selenium web driver, selenium RC, Bugzilla etc.
This step involves planning, scheduling and managing the embedded process in another environment.
This is where all products and files for deployment are executed on the server.
Once the product or application is deployed, it is delivered to the customer for use where they use the product or application for everyday purposes.
This step monitors the delivery of the product or application (enterprise application development services) to the user to record any malfunctions and downtime, errors.
After monitoring, it collects all the information and feedback from the customer and plans the changes that need to be made to make it better.
The different phases of the DevOps lifecycle
Let’s discuss the phases of the DevOps lifecycle to better understand it.
- Continuous development
- Continuous integration
- Continuous testing
- Continuous monitoring
- Continuous feedback
- Continuous development
In this phase of development, a set of goals are developed that should be necessary to implement the application. Once these project goals are completed, the code development process begins. After development, it moves on to the next stage. As DevOps (devops services) follows the continuous development, it also works with the previous application to make changes according to feedback and compliance.
After continuous development comes the continuous integration phase, where various tests are planned for the next phase. This helps us to know if the developed application meets the desired requirements or not.
Continuous integration is a continuous process that leads to the next phase inefficiently.
In the continuous testing phase, the developed application is tested using automation tools. The testers test the application using different test cases and produce results on different aspects of the product or application. These results are then fed back into the development process to improve the product or application.
This is a critical phase in the DevOps lifecycle where the usage of the application or product is monitored. In this phase, the performance of the application or product is closely monitored and logged using tools like Splunk, ELK Stack, Nagios etc. D. Problem areas are then identified. And if there are any problems, it will give the development team a solution to that problem, bug detection and fixing. At this stage, the focus will be on optimum performance and uptime.
The development of a product or application is continuously improved by analyzing the results of all the phases, i.e. Monitoring, testing, etc. This process is done in this continuous feedback phase. This phase is between the development phase and the exploitation phase of the next version of the product or application.
This continuous feedback phase is very important in the DevOps lifecycle because it gives feedback about the product or application earlier after development and before the product is delivered to the customer. Thus, it is easy to eliminate these errors and improve the effectiveness of the product or application. This saves time for the organization.
Benefits of DevOps lifecycle
This method is simple to implement and tasks can be easily organized.
Due to the rigid model DevOps is easy to manage.
There is constant monitoring and debugging, so it is less vulnerable and has fewer loopholes for errors.
Disadvantages of DevOps lifecycle
It cannot be used when dealing with complex and object-oriented models.
This method does not take into account changing requirements.
DevOps is improves organizational efficiency and saves time by allowing users or customers to contribute directly to the product or application development process by sharing ongoing feedback.
