The DevPortal Ecosystem

Workflow and Pipelines in the DevPortal Ecosystem

Product Owner

The PO owner gathers feedback from users and stakeholders, and creates user stories in the backlog. The backlog and stories that comprise the current sprint are kept up-to-date in DevOps.

Developers & the Dev Site

Developers pick up user stories to work on from the current sprint in DevOps. In GitHub, they create a branch from the main code repo to develop the relevant feature/functionality. When they’re ready to merge their code, they create a pull request which, on approval from another developer, auto-merges with the main code. These changes are then automatically deployed to the dev site.

Testers & the Test Site

Code and content changes are scheduled to be deployed to the test site daily at 6am. Having a dedicated, stable test site which is isolated from the multiple changes devs make during the day means we have a reliable environment for rigorous testing.

Testers create test plans and test cases in DevOps and monitor the sprint board for user stories that are ready for testing. Testers log test results and any bugs found in DevOps and coordinate with devs to fix and re-test as needed.

Users & the Main Site / the Beta Site

After each fortnightly demo, stable updates are deployed to the main website. Users and stakeholders can contribute content, suggest changes and submit feedback directly.

The beta site is regularly updated with the latest features and functionality to allow early adopters the opportunity to interact with the newest functionality, even if it’s not working perfectly yet. Similar to a UAT environment, users who choose to engage with the beta site can provide feedback and suggestions to the team/PO while the developers are working through any bugs.

Moderators

All changes go through our site moderators and are reviewed before approval. Any approved changes are auto-merged with the content code repo which is subsumed by the main DP code repo before being deployed to the relevant sites.

Why Use GitHub Code Repositories and Pipelines?

Using GitHub repos and pipelines can offer significant efficiency advantages compared to traditional development and testing environments for several reasons:

Version Control: GitHub repositories provide robust version control. This means that all changes made to the codebase are tracked, logged, and can be easily reverted if necessary. In traditional environments, version control may not be as comprehensive, making it more challenging to manage changes, especially when multiple team members are involved.
Collaboration: GitHub facilitates collaborative development. Multiple developers can work on the same codebase simultaneously, and changes can be merged seamlessly. Traditional development environments may require more manual coordination and are more prone to conflicts and code clashes.
Quality/Automated Testing: GitHub pipelines allow for automated testing. This means that as soon as code is committed, it can be automatically tested, reducing the time it takes to identify and rectify issues. Traditional environments often require manual testing, which can be time-consuming and prone to human error.
Continuous Integration: GitHub pipelines can be configured to implement CI/CD practices. This streamlines the development process, ensuring that code is continuously integrated and tested. In traditional environments, CI/CD may not be as well-implemented, leading to longer development cycles and slower time-to-market.
Automation: GitHub actions can automate various development and deployment tasks, and we take advantage of this by using a combination of automatic, scheduled and manual triggers for executing the GitHub workflows. Traditional environments often involve more manual steps and are therefore less efficient, with more opportunities for human error.
Scalability/Resource Allocation: GitHub pipelines can be scaled to allocate resources as needed. This flexibility ensures efficient resource use, whereas traditional environments may require fixed, often under-used resources.
Traceability: GitHub provides detailed insights into code changes, including who made them and when. This traceability is crucial for identifying issues and tracking progress. Traditional environments might lack such comprehensive tracking mechanisms or rely on manual frameworks.
Iterative/Reduced Downtime: GitHub’s CI/CD capabilities can result in reduced downtime during updates because changes can be tested and deployed quickly. Traditional environments may require scheduled downtimes for manual updates and testing, impacting user accessibility.
Consistency: Using GitHub pipelines ensures consistency in the deployment process. Traditional environments may be more prone to inconsistencies caused by manual interventions, leading to potential issues and longer debugging times.
Error Handling: GitHub pipelines can be configured to automatically handle errors during deployment. Traditional environments may rely more on manual error detection and correction, leading to delays in issue resolution.

In summary, GitHub repos and pipelines offer efficiency and improvements through comprehensive version control, collaboration, automation, and continuous integration. These features reduce the time required for testing and deployment, leading to faster development cycles and more reliable code releases compared to traditional development and testing environments.
