Technology chosen to endure long-term operations.

The UNISYS stack is chosen for long-term operability, not trends. From architecture and cloud to security and DevOps — every decision assumes the operations phase.

/02ARCHITECTURE PHILOSOPHY

Design Principles

Every system is designed on top of these four principles.

A-01

Stateless First

We keep state in the data layer and design services to scale horizontally.

A-02

Observable by Default

We build logs, metrics, and traces to be monitored in a unified view from day one.

A-03

Recoverable

We assume failure and design automated recovery flows and backup policies together.

A-04

Cost-aware

We track performance and cost simultaneously and factor operational efficiency into our decisions.

/04SECURITY · OBSERVABILITY

Security and monitoring,
built into the design from the start

Authentication, authorization, audit logging, and encryption — we define them all early in every system's design.

S-01

Identity & Access

An authorization model based on OAuth2 / OIDC / RBAC, with SSO integration.

S-02

Audit Logging

Every operational action and data access preserved in an immutable log.

S-03

Encryption

Data encrypted both in transit and at rest, with automated key rotation.

S-04

Monitoring

Real-time monitoring of anomalies, error rates, and latency, with automatic alerts.

S-05

Incident Response

Automated rollback, recovery, and post-incident analysis flows when failures occur.

S-06

Compliance

Regular reviews aligned with standards for handling personal and payment data.
