Microservices that
Scale Without Fragility.

Move beyond “just split the monolith.” We design domain-aligned services with stable contracts, event-driven workflows, and platform-grade observability—so your releases get faster and your ops get calmer.

Beyond the Monolith Split.
Production, Not a Service Zoo.

Microservices fail when teams ship unclear boundaries, chatty dependencies, and no ops standards. We engineer the architecture, contracts, and platform foundations so it works on Day 2.

The Microservices Failure Pattern

What most teams accidentally create:

  • Boundary Confusion

    Services overlap domains; ownership is unclear and changes cascade.

  • Distributed Monolith

    Sync calls everywhere, brittle coupling, and latency dominoes.

  • No Operating Model

    Missing SLOs, tracing, runbooks, and governance standards.

The Coretus Microservices Standard

Platform-grade microservices:

  • DDD-First Decomposition

    Domain maps, bounded contexts, and ownership boundaries that hold under growth.

  • Contracts + Async-by-Default

    Versioned APIs, schemas, eventing, and safe evolution paths.

  • Observability + SRE Operating Model

    Tracing, logs, metrics, SLOs, and runbooks embedded from day one.

Less Coupling. More Shipping.

Strategic Capabilities.

From single releases to continuous delivery at scale.

Domain Decomposition (DDD)

Bounded contexts, service boundaries, and team ownership models that survive growth.

  • Context Mapping
  • Ownership Lines

Service Contracts

  • Consumer-Driven Testing

Event-Driven Workflows

Async patterns that reduce coupling: events, sagas, outbox, and idempotent handlers.

  • Sagas + Orchestration
  • Exactly-Once Mindset

Gateway + Routing

API gateway patterns, rate limiting, auth, and traffic shaping without killing velocity.

  • Zero-Trust Gate
  • Traffic Policies

Resilience + SRE

Timeouts, retries, bulkheads, circuit breakers, and SLO-driven reliability.

  • SLOs + Error Budgets
  • Runbooks + On-Call

Observability

Tracing, metrics, logs, dashboards, and alert design for distributed systems.

Service Identity
Microservices Architecture

How do you pick service boundaries?

We use DDD context mapping, ownership lines, and change-frequency analysis to avoid boundary churn.

How do you prevent breaking changes?

Contract versioning, schema governance, consumer-driven tests, and rollout patterns are baked in.

Async workflows vs sync calls?

We default to events where it reduces coupling—using outbox/idempotency patterns for reliability.

Observability from day one?

Yes—traces, logs, metrics, SLOs, and alert design are part of the baseline, not an afterthought.

Governance without slowing teams?

Policy-as-code guardrails + standard templates let teams move fast while staying safe.

Decomposition Audit?

We can deliver a rapid audit to map domains, coupling, and a safe carve-out plan for your highest-impact area.
