Energie Schweiz - Azure Cloud Migration
★ FeaturedMigrated the stable and secure architecture of Energie Schweiz to Microsoft Azure Cloud due to an expiring contract with the previous hosting provider.
Technical Challenges
- Transitioning from Gitlab to Azure DevOps ecosystem
- Migrating from Kubernetes to Azure App Service while maintaining functionality
- Ensuring zero downtime during the migration process
- Completing the migration within a tight 3-week timeframe
Solutions
Implemented a phased migration approach with comprehensive testing at each stage. Developed automated deployment pipelines in Azure DevOps to replace Gitlab CI/CD workflows. Created detailed mapping between Kubernetes configurations and Azure App Service settings.
Outcomes
- Successfully completed the migration within the 3-week deadline
- Achieved zero downtime during the transition
- Improved deployment reliability and simplified infrastructure management
Project Overview
This project involved migrating the stable and secure architecture of Energie Schweiz to Microsoft Azure Cloud due to an expiring contract with the previous hosting provider. The migration needed to be completed within a tight 3-week timeframe while ensuring zero downtime.
Technical Challenges
The migration presented several significant technical challenges:
- Transitioning from Gitlab to Azure DevOps ecosystem: We needed to migrate all repositories, CI/CD pipelines, and development workflows to a completely different platform.
- Migrating from Kubernetes to Azure App Service: The existing application was running on Kubernetes, and we needed to adapt it to run on Azure App Service without losing any functionality.
- Ensuring zero downtime: The website needed to remain accessible throughout the migration process.
- Tight timeframe: The entire migration had to be completed within 3 weeks due to the expiring contract.
Solutions Implemented
To address these challenges, we:
- Implemented a phased migration approach with comprehensive testing at each stage
- Developed automated deployment pipelines in Azure DevOps to replace Gitlab CI/CD workflows
- Created detailed mapping between Kubernetes configurations and Azure App Service settings
- Set up parallel environments to allow for testing before the final cutover
Outcomes
The project was a success, with the following outcomes:
- Successfully completed the migration within the 3-week deadline
- Achieved zero downtime during the transition
- Improved deployment reliability and simplified infrastructure management
- Reduced operational costs while maintaining performance
