How Sentrynex Modernized a Legacy Insurance Infrastructure with Zero Downtime
When a major insurance firm needed to modernize its infrastructure without compromising strict regulatory compliance, Sentrynex stepped in to orchestrate a massive migration of over 230 repositories. We streamlined their CI/CD pipelines, overhauled their secrets management, and optimized Azure DevOps agents, resulting in a secure, scalable, and automated cloud ecosystem.
Overview
A major insurance company partnered with Sentrynex.net to modernize its software delivery infrastructure on Microsoft Azure. The goal was ambitious: migrate over 230 repositories, rebuild CI/CD pipelines, optimize Azure DevOps agents, and replace legacy secrets management—all while maintaining strict security and compliance standards.
The Challenge
The client’s legacy environment had become a bottleneck. With 230+ repositories scattered across systems, fragmented CI/CD pipelines, and an outdated secrets library, the insurance provider faced rising security risks and slowing release cycles.
Key challenges included:
- Migrating 230+ repositories to Azure Repos without disrupting active development.
- Rebuilding and standardizing CI/CD pipelines for consistency and speed.
- Securing sensitive data, including connection strings, API keys, and secret files.
- Optimizing Azure DevOps agents to handle increased build and deployment loads.
- Meeting insurance industry compliance and audit requirements.
The Solution
Sentrynex.net executed a comprehensive Azure migration and DevOps modernization strategy.
1. Repository Migration at Scale
We migrated 230+ repositories to Azure Repos, consolidating source control and enabling better access management, auditing, and collaboration across teams.
2. CI/CD Pipeline Modernization
Legacy pipelines were replaced with modern YAML-based multi-stage pipelines in Azure Pipelines. This improved build reproducibility, enabled environment-specific deployments, and reduced manual intervention.
3. Secure Secrets Management
We retired the client’s legacy secrets library and secret files, moving all sensitive data to Azure Key Vault. Managed Identities and strict access policies eliminated hard-coded credentials and reduced the risk of exposure.
4. Azure DevOps Agent Optimization
We redesigned the agent architecture, combining Microsoft-hosted and self-hosted agents to balance performance and cost. This reduced build times and improved pipeline reliability.
5. Security & Compliance Integration
Automated security scanning and approval gates were embedded into the pipelines, ensuring every deployment met the client’s regulatory and internal security standards.
The Results
The migration was completed with zero downtime and no disruption to policyholder services.
- 230+ repositories successfully migrated to Azure Repos.
- 100% of secrets moved to Azure Key Vault with Managed Identity access.
- Significantly faster deployments through optimized CI/CD pipelines and agents.
- Improved security posture with centralized secrets management and automated scanning.
- Scalable foundation for future cloud-native development and compliance audits.
