Legacy operations platform modernization illustrative case visual

Context

This illustrative example describes a common modernization shape: an important internal application has become hard to change, test, and operate.

Approach

The first phase would map the architecture, add automated checks around critical workflows, improve release confidence, and identify slices for refactoring or migration.

What this example demonstrates

This is an illustrative modernization pattern, not a client case study. The approach is to make critical workflows testable and choose migration slices based on evidence rather than rewrite momentum.
