To make successful deliveries of applications, development and operations play an essential role. Deployment means analyzing requirements, design, development, and testing of the software components or frameworks.
In DevOps architecture, both the development and operations collaborate to fix the gap between deployment and operation terms; so that delivery can be faster.
This architecture is mainly used for the applications that are hosted on the cloud platform and also for large distributed applications. These days companies are mainly focusing on Agile Development for the early rollout of deliveries. In the DevOps architecture, agile development is used so that integration and delivery can be contiguous. Development and operations team working in silos is time-consuming to design, test, and deploy. And if the teams are not in sync, then it adds to the delay in the delivery. DevOps brings the development and operations team together and increases productivity.
The various components used in DevOps architecture are depicted below:
1) Build
In absence of DevOps, the cost of the consumption of the resources was evaluated based on the individual usage hardware allocation. With DevOps, the sharing of resources and usage of the cloud is enabled. The build is dependent upon the user's need, hence the usage of resources or capacity can be controlled.
2) Code
The code is properly arranged in files, folders, etc., is maintainable, and can be reused.
3) Test
After testing the application is ready for production. Manual testing consumes more time in testing and moving the code to the output. By automating the testing, the time taken for testing is decreased and the time taken to deploy the application to production is also reduced. With automation, the test case execution is faster and removes the time taken in performing manual steps.
4) Plan
In DevOps, planning for development is done using Agile methodology. Since the operations and development team are in sync, the plan to work is organized and accordingly, it increases productivity.
5) Monitor
Continuous monitoring of the application is required and used to identify any risk of failure. It also helps in tracking the health status of the application. There are many third-party tools used for monitoring such as Splunk.
6) Deploy
A scheduler for automated deployment is supported by many systems in the current scenario. With the help of a cloud management platform, users are enabled to capture accurate insights and view the optimization scenario, analytics on trends by the deployment of dashboards.
7) Operate
Before DevOps, the traditional approach of developing and testing separately was followed. With DevOps, both the development and operations teams operate collaboratively by actively participating throughout the service lifecycle. The operation team interacts with developers, and together they come up with a monitoring plan which serves the IT and business requirements.
8) Release
Deployment to an environment is done by automation. But deployment to the production environment is done manually. There are many processes involved in release management that are commonly used to do the deployment in the production environment manually so that there is less impact on the customers.
