Microservices Development Services

Microservices is an architectural decision with a real cost — operational complexity, distributed-system failure modes, and team-coordination overhead — paid for, ideally, by independent deployability and clearer service ownership boundaries. We push back when customers ask for microservices for the wrong reasons (resume-driven design, vendor pressure, premature abstraction) and recommend a modular monolith first when the load profile and team size don't justify the complexity yet.

When microservices are right, our stack covers Docker for containerisation, Kubernetes for orchestration (EKS, GKE, AKS, or self-managed depending on customer preference), API gateways (Kong, AWS API Gateway, Apigee), and service mesh (Istio or Linkerd where the service count justifies it). Observability is non-negotiable: OpenTelemetry instrumentation, distributed tracing via Jaeger or Tempo, metrics into Prometheus + Grafana or Datadog, structured logging into Elasticsearch or CloudWatch.

Decomposition follows the strangler fig pattern — incremental, with contract testing (Pact) enforcing the boundary as it shifts. Greenfield microservices start with the boundary map, not the framework choice. Either way, the migration plan includes a written rollback strategy at every step.

03 E-Commerce

Product catalogue, order management, payment processing, and inventory services that scale independently during peak traffic. We implement saga patterns for distributed transactions and circuit breakers to isolate payment gateway failures from the broader shopping experience.

Our e-commerce microservices include real-time inventory tracking, personalised recommendation engines, and seamless checkout experiences that drive conversions and operational throughput.

E-commerce microservices with independent scaling and saga patterns

Healthcare and EdTech microservices with strict compliance boundaries

04 Healthcare & EdTech

Patient management, appointment scheduling, and student assessment services built with strict data isolation and compliance boundaries. Each service enforces its own authentication context and data encryption policies, meeting HIPAA and regional privacy requirements without imposing those constraints on non-sensitive services.

Our microservices support real-time progress tracking, secure record retrieval, and seamless integration with existing hospital systems and learning management platforms.

Process Workflows

Microservices Development Workflow

An iterative process guiding the development, deployment, and maintenance of individual microservices, emphasising agility and continuous improvement.

Design

Define business functionality for each microservice, design API endpoints and data formats, and select appropriate technologies. We break down complex functionalities into independent, scalable, and maintainable services.

Development

Implement code based on design specifications, conduct unit tests for component validation, and perform regular code reviews. Our collaborative approach identifies issues early to improve stability.

Deployment

Containerize each microservice with its dependencies and implement CI/CD pipelines. We automate deployment to dev, testing, and production environments, ensuring consistency and faster deployment cycles.

Testing

Conduct integration testing for service interactions, end-to-end testing for application flow, and performance testing for traffic handling to ensure scalability and resilience under load.

Monitoring & Maintenance

Collect logs and metrics for performance tracking, scale resources to meet demand fluctuations, and regularly update with bug fixes and new features to ensure efficiency and responsiveness.

Retirement

Plan service deprecation and inform stakeholders, migrate necessary data to other services, and safely shut down retired services while maintaining proper records for future reference.

Agile Outcomes

Adapting to Change

Extract, deploy, and scale services independently — without betting the business on a big-bang rewrite.

FAQs

Your Microservices Questions, Answered

Real answers to the questions our clients ask before adopting microservices architecture with Brainstack.

01. Is microservices architecture the right choice for my project?

Not always — and that honesty saves our clients time and money. Microservices make sense when you have multiple teams needing independent deployment cadences, services with genuinely different scaling profiles, or polyglot requirements. For smaller teams or early-stage products, a well-structured modular monolith is often the smarter starting point. We’ll help you evaluate based on your team size, operational maturity, and business goals.

02. How does Brainstack approach microservices design and service decomposition?

We start with your domain, not the technology. Using Domain-Driven Design (DDD), we identify bounded contexts, map your business capabilities, and define service boundaries that align with how your organisation actually works. This prevents the common mistake of splitting too early or too finely — which creates distributed complexity without real benefit.

03. What happens to our data when splitting a monolith into microservices?

Each microservice should own its data. We design data ownership boundaries carefully, implement the database-per-service pattern where appropriate, and use event-driven patterns (event sourcing, CDC) to keep services in sync without tight coupling. For the transition period, we run parallel systems and validate data consistency at every step.

04. How do you handle communication between microservices?

We use synchronous communication (REST, gRPC) for request-response flows and asynchronous messaging (Kafka, RabbitMQ, AWS SQS) for event-driven workflows. The choice depends on latency requirements, coupling tolerance, and failure handling needs. We also implement patterns like circuit breakers, retries with backoff, and dead-letter queues to handle distributed failures gracefully.

05. What tools and platforms do you use for microservices orchestration?

Docker for containerisation, Kubernetes (EKS, GKE, or AKS) for orchestration, Helm for deployment management, and Istio or Linkerd for service mesh when needed. For CI/CD, we use GitHub Actions, GitLab CI, or ArgoCD with GitOps workflows. We pick the toolchain based on your cloud provider, team familiarity, and operational complexity budget.
