Custom Microservices

Modular, Scalable Architecture for Modern Applications

Break free from monolithic constraints. We design and build production-grade microservices architectures that let you scale individual components independently, deploy with confidence, and move faster than your competition.

What Are Custom Microservices?

Microservices architecture decomposes a complex application into a collection of small, autonomous services. Each service is independently deployable, owns its own data store, and communicates through well-defined APIs. The result is a system that scales horizontally, tolerates failure gracefully, and evolves without the risk of breaking everything at once.

Unlike a monolith where a single bug or bottleneck can cripple your entire platform, microservices isolate failures and allow surgical updates. Teams can work on individual services in parallel, using the best technology for each problem, and ship continuously without coordination overhead.

At Synexian, we go beyond splitting codebases. We apply domain-driven design to identify service boundaries, implement event-driven patterns for resilient communication, and deploy everything into container orchestration platforms built for enterprise-grade reliability.

Everything You Need to Build at Scale

Every engagement is built on a battle-tested foundation of distributed systems patterns, cloud-native tooling, and operational best practices.

Service Decomposition

We apply domain-driven design and bounded context analysis to identify the right service boundaries for your business domain, avoiding the distributed monolith anti-pattern from day one.

API Gateway & Routing

Centralized API gateway configuration for authentication, rate limiting, request routing, and protocol translation. Supports REST, gRPC, and GraphQL with zero-downtime traffic management.

Service Mesh Security

Mutual TLS encryption between every service, zero-trust network policies, and fine-grained traffic controls via Istio or Linkerd. Security is a first-class concern, not an afterthought.

Database Per Service

Each microservice owns its own isolated data store, eliminating tight coupling and shared schema nightmares. We design polyglot persistence strategies — SQL, NoSQL, time-series, or in-memory — matched to each service's needs.

Event-Driven Architecture

Asynchronous, resilient communication between services using Apache Kafka, RabbitMQ, or AWS EventBridge. Saga patterns handle distributed transactions. Event sourcing provides a reliable, auditable history of all state changes.

Container Orchestration

Production-hardened Kubernetes deployments with auto-scaling, self-healing, rolling updates, and blue-green release strategies. Full Helm chart configuration, resource policies, and namespace isolation included.

From Concept to Production

A structured, proven process that delivers production-ready microservices architecture without surprises.

01

Domain Analysis & Decomposition

We work with your team to map your business domains, identify bounded contexts, and define service boundaries using event storming workshops. This phase prevents over-engineering and under-splitting.

02

Service Architecture Design

API contracts, data models, communication patterns, and infrastructure topology are documented in full architecture decision records. You own the documentation before a single line of code is written.

03

Development & Containerization

Services are built with clean, test-covered code, each shipped as an optimized container image. CI/CD pipelines enforce quality gates — unit tests, integration tests, security scans — on every commit.

04

Deployment & Orchestration

Kubernetes manifests, Helm charts, and infrastructure as code are handed over alongside full observability setup — distributed tracing, centralized logging, and dashboards ready on day one in production.

Built for Every Domain

Microservices architecture has proven its value across industries. Here is where we deliver the most impact.

🛒

E-Commerce Platforms

Separate catalog, cart, payments, inventory, and recommendations into independently scalable services. Handle flash sale traffic spikes without over-provisioning the entire stack.

🏦

Financial Systems

Isolated transaction processing, fraud detection, and reporting services with strict audit trails and compliance boundaries. Distributed saga patterns ensure financial consistency without distributed locks.

SaaS Applications

Multi-tenant architectures where authentication, billing, notifications, and core product features evolve at their own pace. New capabilities ship without coordinated releases across the whole platform.

🔋

IoT Backends

Ingest, process, and route millions of device events per second with independently scalable ingestion, processing, and storage services. Event-driven patterns handle burst traffic naturally.

📈

Real-Time Analytics

Streaming data pipelines where collection, enrichment, aggregation, and serving tiers scale independently. Kafka-based architectures process events with sub-second latency at any volume.

🔄

Legacy Modernization

We apply the strangler fig pattern to incrementally extract services from your existing monolith — zero downtime, zero big-bang rewrites. Your users never notice the transformation happening underneath.

The Synexian Difference

We do not just build microservices. We build the operational foundation that makes them run reliably in production for years.

Architecture-First Thinking

Every engagement starts with deep domain analysis before any code is written. We document architectural decisions as ADRs so your team understands the reasoning behind every design choice — not just the output.

Observability from Day One

We instrument every service with OpenTelemetry distributed tracing, structured logging, and Prometheus metrics before production launch. You see exactly what is happening inside your system at all times.

CI/CD and DevOps Included

Every service ships with its own automated pipeline: build, test, security scan, containerize, and deploy. No manual steps, no configuration drift. Your team inherits a mature DevOps culture alongside the codebase.

Knowledge Transfer Built In

We treat your team as collaborators, not bystanders. Pair programming sessions, architecture walkthroughs, and comprehensive runbooks ensure your engineers can own and evolve the system long after we hand it over.

Frequently Asked Questions

Answers to the questions we hear most often from teams evaluating microservices architecture.

What are microservices and how do they differ from a monolith?
Microservices are an architectural approach where an application is broken into small, independently deployable services that each own a specific business domain. Unlike a monolith where all functionality is bundled together, microservices allow teams to develop, deploy, and scale each service independently. This reduces risk, accelerates delivery, and means a failure in one service does not cascade across your entire platform.
When should I consider migrating to microservices?
Microservices become beneficial when your monolith experiences scaling bottlenecks, deployment slowdowns, or team coordination overhead. If certain components need to scale independently, or multiple teams are frequently blocked by shared code and release schedules, microservices provide significant operational and development velocity gains. Microservices are not always the right answer — we will tell you honestly if your situation does not warrant the added operational complexity.
What technologies do you use to build microservices?
We work with a modern, cloud-native stack including Docker for containerization, Kubernetes for orchestration, Istio or Linkerd for service mesh, Kong or AWS API Gateway for API management, and event brokers like Apache Kafka or RabbitMQ for async communication. Language choice is tailored to each service's requirements — Python, Go, Node.js, and Java are all within our expertise. We are cloud-agnostic: AWS, GCP, and Azure are all supported.
How do you handle data consistency across multiple microservices?
We apply patterns like the Saga pattern for distributed transactions, event sourcing to maintain reliable audit trails, and CQRS to separate read and write models. Each service owns its own database, and we use eventual consistency models where strong consistency is not required, ensuring resilience without sacrificing correctness. Where strict ACID guarantees are needed — such as in financial systems — we design service boundaries specifically to avoid distributed transactions rather than fighting against eventual consistency.
How long does it take to build a microservices architecture?
Timeline depends on system complexity and scope. A greenfield microservices platform typically takes 8 to 16 weeks for the initial production-ready core. Legacy modernization projects are phased — we commonly start with a strangler fig pattern over 3 to 6 months to incrementally decompose the monolith with zero downtime. We provide a detailed project breakdown with milestones during the free consultation so you have full visibility into the timeline before any commitment.
Do you provide ongoing support and monitoring after deployment?
Yes. Every microservices engagement includes a production readiness review covering observability, alerting, and runbooks. We set up distributed tracing with OpenTelemetry, centralized logging via ELK or Loki, and Prometheus and Grafana dashboards ready from day one in production. Ongoing support and SLA-backed maintenance packages are available post-launch — from ad-hoc consulting to fully managed infrastructure support.
