Microservices Architecture

Break the monolith - scale each piece independently

We design and build microservices architectures that let your teams develop, deploy, and scale services independently - without the coordination overhead that slows monoliths down.

  • Monolith decomposition and service design
  • Event-driven and API-first architecture
  • Container orchestration with Kubernetes

What we deliver

Microservices, done practically

We avoid the complexity trap - services are split where it matters and kept simple where it does not.

Domain-driven design

Bounded contexts and service boundaries aligned with your business domains.

Event-driven messaging

Async communication via Kafka, RabbitMQ, or SQS for loose coupling and resilience.

API gateway

Centralized routing, auth, rate limiting, and versioning for your service mesh.

Service mesh

Observability, traffic management, and mTLS between services.

Distributed tracing

End-to-end request tracing across services for fast debugging.

Data patterns

Database-per-service, CQRS, event sourcing, and saga patterns for data consistency.

How it works

Independent teams, independent deployments

Each service owns its domain, its data, and its deployment pipeline. Teams move fast without stepping on each other, and failures in one service do not cascade to others.

  • Each service independently deployable and scalable
  • Circuit breakers and bulkheads for fault isolation
  • Shared nothing - services communicate via APIs and events

How we work

From monolith to microservices

An incremental approach that delivers value at each step.

  1. 01

    Analyze the monolith

    We map domains, dependencies, and identify the highest-value services to extract first.

  2. 02

    Design service boundaries

    We define APIs, data ownership, and communication patterns.

  3. 03

    Extract and build

    We incrementally extract services, keeping the monolith running throughout.

  4. 04

    Set up orchestration

    We deploy container orchestration, service mesh, and observability.

  5. 05

    Optimize and expand

    We refine patterns and continue decomposition based on team and business needs.

The payoff

What microservices unlock

Organizational and technical agility.

Faster delivery

Teams deploy their services independently without coordinated release windows.

Independent scaling

Scale hot services without scaling the entire application.

Fault isolation

A failure in one service does not take down the whole system.

Team autonomy

Teams own their services end to end - code, deploy, monitor.

Technology flexibility

Each service can use the best language and framework for its job.

Easier maintenance

Smaller codebases are easier to understand, test, and refactor.

FAQ

Questions, answered

Still deciding? These are the things teams ask us most - and if yours isn't here, a 30-minute call will cover it.

Not always. We honestly assess whether the complexity is justified for your team size, deployment needs, and growth trajectory.

Yes. We recommend the strangler fig pattern - extracting services one at a time while the monolith continues to run.

With patterns like saga, event sourcing, and eventual consistency - chosen based on your consistency requirements per domain.

We mitigate it with standardized templates, shared libraries, observability, and clear documentation.

Cross-functional teams aligned to business domains, each owning one or more services end to end.
