Why MSA

Overcome Monolithic
Limitations with MSA

Traditional monolithic architectures become exponentially more complex in development, deployment, and scaling as systems grow. MSA separates services into independent units, enabling teams to develop autonomously, deploy independently, and scale individually as needed.

Independent Deployment
Deploy each service independently, minimizing impact on the entire system
Technology Diversity
Choose the optimal tech stack for each service
Fault Isolation
Failures in one service don't affect the entire system

What We Do

End-to-End
MSA Implementation

01

Architecture Design

Define service boundaries through domain analysis and design optimal MSA architecture. We present a feasible roadmap considering business requirements and technical constraints.
02

Service Decomposition

Analyze monolithic systems and decompose them into independent microservices. We define data separation, API design, and inter-service communication to support gradual transition.
03

Container Orchestration

Build container-based infrastructure using Kubernetes and Docker. Ensure stable service operation with auto-scaling, self-healing, and rolling updates.
04

API Gateway

Consolidate service entry points and handle authentication, authorization, routing, and load balancing. Support stable service exposure with API versioning and rate limiting.
05

Service Mesh

Manage inter-service communication through Service Mesh like Istio and Linkerd. Handle traffic control, secure communication, and service discovery at the infrastructure level.
06

DevOps Pipeline

Build CI/CD pipelines to automate build, test, and deployment. Maintain consistent deployment environments with GitOps-based infrastructure management.

MSA Transformation

We decomposed a legacy monolithic system into over 50 microservices and transformed it to a Kubernetes-based cloud-native architecture. Deployment frequency improved from monthly to over 10 times daily.

Benefits

MSA Benefits

10x

Deployment Speed

Significantly shorten release cycles with independent service deployment.

Scalability

Selectively scale only the services you need horizontally.

Team Autonomy

Each team develops and operates their services independently.

Fault Impact

Service isolation prevents failures from spreading to the entire system.
