A microservices architecture breaks large applications into smaller, independent services, each responsible for a specific business capability. Done well, it transforms how quickly and safely you can deliver change. Done badly, it creates a distributed monolith that is harder to run than what it replaced. We help you get it right.
Why microservices
- Agility: teams develop, deploy and iterate on individual services independently.
- Scalability: each service scales horizontally according to its own demand.
- Resilience: failures are isolated to a single service rather than cascading across the system.
- Maintainability: smaller codebases are simpler to understand, test and update.
Architecture
Service boundaries
We use domain-driven design to decompose your application along clear business boundaries, with each service owning its own data. This is the single most important decision in a microservices architecture.
APIs and communication
- Consistent, well-documented REST or gRPC APIs, published through an API gateway
- Event-driven integration with message brokers and streaming platforms such as Apache Kafka, RabbitMQ or cloud-native queues, for loose coupling and scalability
- Service discovery and configuration management
Resilience patterns
Timeouts, retries with back-off, circuit breakers, bulkheads and idempotent operations, so that one slow service never takes the whole platform down.
Security
Zero-trust networking with mutual TLS between services, OAuth 2.0 and OpenID Connect for identity, and least-privilege access to data and secrets.
Automating the platform
- Containerised services running on Kubernetes or serverless platforms
- CI/CD pipelines that build, test and deploy each service independently
- Infrastructure as code for every environment
- Distributed tracing, metrics and centralised logging with OpenTelemetry, for fast diagnosis
- A service mesh where traffic management and security requirements justify it
Migrating from a monolith
We move you incrementally using the strangler-fig pattern, extracting one capability at a time without disrupting the business. We will also tell you when a well-structured modular monolith is the better choice. Microservices are a means to an end, not a goal in themselves.
