Client Brief

A leading North American organization partnered with Sujosu Technology to transition their existing Classic pipelines to Multistage YAML pipelines to leverage advanced CI/CD capabilities. The client’s application repository utilized a custom build pipeline script rather than the standard DevSecOps (DSO) Template, adding complexity to the project.

Key Features

The migration to Multistage YAML pipelines was successfully completed within the stipulated timeframe, delivering the following results:

  1. Improved CI/CD Process: The YAML pipeline structure offered greater flexibility, scalability, and maintainability compared to the Classic pipeline.

  2. Enhanced Visibility: With well-defined stages and improved logging, the new pipeline provided better transparency into the CI/CD process.

  3. Time Efficiency: The transition was executed without delays, ensuring minimal disruption to the client’s operations.

  4. Future-Ready Workflows: The YAML pipelines positioned the client’s CI/CD workflows for scalability and adaptability, meeting modern DevOps      standards.

  5. Seamless Transition: Sujosu Technology’s meticulous planning and execution ensured a smooth migration, preserving the functionality of the custom script.

  6. Operational Confidence: The improved pipeline design instilled confidence in the client’s development teams, enabling them to focus on      innovation and delivery.

This case study demonstrates Sujosu Technology’s capability to manage complex pipeline transitions with precision and efficiency. By successfully migrating from Classic pipelines to Multistage YAML pipelines, Sujosu Technology empowered the client with a modernized CI/CD framework tailored to their unique requirements, reaffirming its role as a trusted partner in driving DevOps innovation and operational excellence.

Challenges

The transition to Multistage YAML pipelines presented several key challenges:


  1. Custom Pipeline Script: The client’s reliance on custom scripts necessitated      an in-depth review to identify specific areas requiring modifications.

  2. Seamless Migration: Ensuring a smooth transition from Classic pipelines to YAML pipelines while preserving functionality and minimizing disruptions.

  3. Time Constraints: Completing the migration within a predefined timeline to align with the client’s operational schedules.

Our Solution

Phase 1: Comprehensive Pipeline Analysis

  • The team conducted an extensive review of the existing custom-build pipeline script to understand its structure, dependencies, and functionality.

  • Key stages, tasks, and integrations within the script were mapped to identify how they could be replicated or improved using Multistage YAML pipelines.


Phase 2: Designing the Multistage YAML Pipeline

  • Stage Segmentation: The pipeline was designed to reflect distinct stages (e.g., build, test, and deploy) with clearly defined inputs and outputs.

  • Custom Integration: Elements from the custom script were carefully incorporated into the YAML pipeline, ensuring compatibility with the client’s repository and workflows.

  • Error      Handling: Enhanced logging and error-handling mechanisms      were added to streamline troubleshooting and improve pipeline resilience.


Phase 3: Testing and Validation

  • The newly developed Multistage YAML pipeline underwent iterative testing to validate      functionality and performance.

  • Comparisons were made with the Classic pipeline to ensure parity in outputs while leveraging the enhanced flexibility of YAML pipelines.


Phase 4: Deployment and Transition

  • The final Multistage YAML pipeline was deployed, replacing the Classic pipeline.

  • The team provided knowledge transfer sessions to enable the client’s developers to effectively manage and extend the YAML pipeline.
