DevOps is a software engineering culture that combines processes, people, and products to facilitate continuous delivery of services to the users at a faster pace. In order to achieve this, it is essential for organizations to follow certain metrics to track DevOps’ success. Some of those metrics are described below.
- Continuous Integration and Continuous Delivery (CI/CD): Today’s markets demand services at a higher velocity. The speed of new integrations/deployments plays a vital role in meeting the project’s/end-users' requirements. The continuous flow of integrations or new code changes are followed by continuous deployments after being tested for changes. These changes are, then, implemented in production to provide continuous delivery of services to the end-users.
- Collaborate: To meet the required objectives, it is imperative for all the teams - Development, Quality Assurance, Operations, and Management – to collaborate frequently in order to define goals, design, develop, and implement the applications in a best-suited manner. The Team Leads/Managers must participate actively in coordinating with the crew when they accomplish a successful delivery of an application.
- Track Changes: It’s crucial to track each code to keep the process running smoothly. This helps in revisiting a specific code whenever the need may arise.
- Track the Number of Failed Deployments: Remember to track the number of deployments that have resulted in the disruption or unfavorable assessment from the users. It is essential to strive for quality from the very first step, instead of considering it after the development, to ascertain the nature of DevOps. It is also suggested to review these metrics as a team to effectively keep a track of failed deployments.
- Mean Time to Recover (MTTR) – Disaster Recovery is crucial to any project. It helps in maintaining the readiness of the application at all times. MTTR is one of the best processes to track complex issues and failures while it helps in assessing the capability of the teams to handle changes and revert whenever required.
- Performance Metrics – The importance of having stable performance metrics, irrespective of any changes in user feedback or deployment indicators, must never be undermined. This critical indicator permits the application to be operational within its predefined boundaries.
- Tracking the Lead Time – Software or applications are developed after new changes are deployed into the production. Cycle time is a good indicator to determine the efficiency of the processes, which helps the team in understanding the areas of improvement and in getting a better hold of the project’s lifecycle.
- Process Automation – Automating the process leads to a quicker execution of various services. This reduces human errors at various levels and helps in boosting the delivery of the product efficiently.
- Cloud Computing – It’s better to operate on Cloud to have a more dynamic hardware infrastructure in the fast-moving world. Cloud computing helps in smooth delivery of an application in many ways, such as auto-scaling, pay-as-you-use, getting instant access to data centers, etc.
- SLAs – Adhering to defined SLAs is the key to accomplish goals within the specified period of time.
Tools that are typically used in a DevOps environment are as follows:
Source Code Repository: GIT, Subversion, TFS, etc.
Build Server: Jenkins, Bamboo, etc.
Configuration Management Tool: Ansible, Puppet, Chef, Salt, etc.
Public Cloud: Google Cloud, Amazon Web Services, Microsoft Azure, etc.
Test Automation Tool: Selenium, Water, etc.
