How JPMorgan Reduced Dependency Update Time by 94%

We orchestrated deterministic dependency updates across thousands of services with regression tests and SBOM generation.

The Challenge

JPMorgan Chase had over 2,000 microservices running on outdated versions of critical dependencies. Manual updates were taking months and creating security vulnerabilities.

The Solution

Using CodeContext's deterministic campaigns, we automated the entire dependency update process:

1. Automated Discovery: Scanned all repositories for outdated dependencies
2. Impact Analysis: Identified potential breaking changes using semantic analysis
3. Staged Rollout: Updated dependencies in dependency order across services
4. Automated Testing: Ran comprehensive test suites for each update
5. SBOM Generation: Created software bills of materials for compliance

Results

• 2,000+ services updated in 48 hours
• 0 production incidents
• 94% reduction in update time
• 100% test coverage maintained
• $3.2M in avoided security incident costs

The key was deterministic execution—every update followed the exact same process, making the entire operation predictable and safe.
