Architecture Principles
The design principles — isolation, least privilege, observability and graceful degradation — behind every Vestval system.
Overview
Trust starts in the architecture. The properties enterprises care about — security, resilience, privacy and reliability — are consequences of how a system is designed, so we hold ourselves to a consistent set of architecture principles across every product.
These principles are not aspirational statements; they are the criteria we design and review against, and they explain why our security and service commitments are achievable.
What this covers
Isolation by default
Tenants, environments and services are isolated so a failure or breach is contained.
Least privilege
Every component and person gets the minimum access required, and nothing more.
Defense in depth
Multiple independent layers of control, so no single failure is catastrophic.
Observability
Systems are instrumented so behavior is measurable, auditable and debuggable.
Graceful degradation
Under stress, capability reduces predictably instead of failing unpredictably.
Immutable & reproducible
Infrastructure as code and reproducible builds make change auditable and reversible.

- Multi-tenant products isolate data at the data layer, and single-tenant deployments provide full environment isolation.
