How to perform DevOps Automation

DevOps encompasses various processes and not all of them can be automated. It’s essential to choose the appropriate processes to automate at the beginning of any software project.

Following are some of the processes that an be best optimized through automation:

1. Planning Phase

It’s imperative to establish a requirements document, and sketch out a plan for the development of the software. This phase is the time DevOps teams use to ideate and decide the features and functions of the software they plan to build, make decisions such as choosing performance metrics, and lastly take feedback from all stakeholders.

At this phase tools such as GitLab, Atlassian, Jira, GitHub, and Azure DevOps can be used to automate certain tasks such as:

• Gathering Stakeholder Feedback
• Issue tracking
• Organizing Information and Prioritizing actions
• Visualizing Progress with Dashboards.

2. Coding Phase

This phase involves the creation and design of software code to fulfill the requirements decided upon during the planning phase.

During this phase it’s imperative to use a source code repository to collaborate and keep track of all code, to review code, and to perform corrections as needed.

At this phase tools such as GitHub, BitBucket, and GitLab can be used to automate certain tasks such as:

• Repetitive manual tasks in code development.
• Code review.

3. Build Phase

In this phase code submitted to the source code repository is compiled and built into artifacts which are executable in different environments. Following this automated unit and regressions tests are run to ensure the code is functional and suitable to be deployed.

The decided performance metrics are used to measure the quality of the code, its performance, its functionality, and other traits prior to release.

At this phase tools such as GitLab, GitHub, Docker, Puppet, Gradle, and CFEngine are employed to automate tasks such as:

• Building the code into executable artifacts.
• Generating statistics.
• Containerized environment creation.
• Generating demo web pages and documentation.
• Automating the iterative testing and review process.

4. Test Phase

This phase involves continuous testing to detect any bugs or defects, validate the code, and ensure that its acceptable according to the requirements document. Quality assurance is also carried out at this stage to verify and approve the code for integration and deployment.

At this phase tools such as Selenium, Cucumber, JUnit, and TestNG are employed to automate tasks such as:

• Automating unit tests and acceptance and regression testing, security and vulnerability analysis, configuration testing, and performance measurement.
• Prioritization and allocation of errors found.

5. Release and Deployment Phase

Once the software or updated feature has passed the Testing Phase and all requirements have been met it can then be deployed. In the case that a new or updated feature is being released the teams will often ensure that back-ups are available in case something goes wrong and then deploy the feature.

During this Phase staging of the release is carried out as well. This step is penultimate to the deployment of the new features/live website. This staging environment is a replica of the live website and the last step where the DevOps team and other stakeholders can test the quality in a production-like environment prior to deployment.

At this phase tools such as Jenkins, AWS CodePipeline, Ansible, Chef, Kubernetes, CircleCI, Docker, and Jira are employed to automate tasks such as:

• Managing, scheduling, and coordinating various feature releases into the live website.
• Network, Data storage, and general configuration management to optimize performance.

6. Operations and Monitoring Phase

Once the software/feature has been deployed it is important to monitor the server and performance of the software to understand the impression it has on its users and to flag incidents early. Continuous feedback from users is also taken in order to continuously improve the application and keep it relevant.

At this phase tools such as Slack, Splunk, Wireshark, Sumo Logic, pendo, and pingdom are employed to automate tasks such as:

• Automation tools that can monitor availability, performance, or security problems and generate alerts based on them help solve this challenge.
• Application monitoring
• Security monitoring
• Alert generation for any incidents or errors
• Monitoring the availability of the software
• Collecting user metrics and feedback
• Creating Visuals for User and Performance Metrics
