Case study

Migration recovery for a B2B SaaS platform

A cloud migration completed on schedule, but stability got worse. Incidents increased, delivery slowed, and the team lost confidence in the platform.

Key signals
  • Routing and latency inconsistencies after the move
  • Permissions drift and unclear ownership boundaries
  • State and config changes done manually to survive
  • Deployments became risky and unpredictable
Context

Stability loss after a successful migration

Environment

A growth-stage SaaS platform with multiple services and a lean platform team.

Trigger

Post-migration incidents increased and delivery reliability declined.

Constraints

Minimal downtime tolerance, no appetite for another full re-architecture.

Goal

Contain risk first, then rebuild predictable delivery.

Intervention

Contain, trace, correct

Contain the blast radius

Freeze unsafe changes, stabilize critical paths, and stop hidden coupling from spreading.

Trace the failure chain

Map latency and errors across networking, identity boundaries, and runtime config.

Repair drift

Normalize configuration, remove unsafe manual patches, and restore clear ownership.

Rebuild delivery confidence

Reintroduce safe promotion paths and consistent deploy behavior.

Outcomes

Stability returned and delivery regained confidence

Lower incident risk

Critical paths were hardened and failure loops removed.

Clearer ownership

Teams understood boundaries and stopped hand-off gaps.

Predictable releases

Deployments were no longer a roulette wheel.

Artifacts delivered

Evidence the team could keep using

Risk map

Prioritized risks tied to business impact and failure paths.

Recovery plan

Sequenced fixes with safe change control.

Architecture notes

Updated diagrams, routing decisions, and ownership boundaries.
