Representative solution scenario · S3
Modernizing a fragile digital platform
Modernization
Starting situation
A customer-facing platform built several years ago runs on manually configured servers. Releases are infrequent and nervous; outages are noticed by customers first.
Operational friction
- Deployments need a specific person and planned downtime
- Little automated testing, so changes cause regressions
- No clear view of performance or errors
- Outdated dependencies with known vulnerabilities
Proposed system
A phased modernization: stabilize with tests and monitoring, move infrastructure to code, automate delivery, then refactor the riskiest parts of the application module by module.
Architecture outline
Experiences
Existing interface retained during transition · Performance improvements on key journeys
Operations
Application modules refactored incrementally · Documented APIs
Intelligence
Error and performance analytics
Foundations
Infrastructure as code · Automated CI/CD · Managed database and backups
Assurance
Automated regression tests · Dependency scanning · Alerting and runbooks
Technologies that may be used
Expected categories of improvement
- Routine, lower-risk releases
- Problems detected before customers report them
- Reduced security exposure
- A codebase that is easier to change
