Overview
What we delivered
An analytics SaaS company was dealing with a slow monolithic platform, rising infrastructure costs, and performance issues in reporting workflows. Stellar Code System modernized the product using Kubernetes microservices and an event-driven architecture, helping the business lower infrastructure spend, improve uptime, and dramatically accelerate reporting performance.
Client
An analytics SaaS provider running a growing product on a legacy monolithic architecture with increasing infrastructure and performance challenges.
Challenge
The company’s monolithic architecture had become expensive to run and too slow for modern reporting expectations. Scaling costs were rising while product performance and reliability were under pressure.
Slow monolith affecting reporting performance
High infrastructure costs
Limited scalability under growing usage
Need for stronger uptime and service resilience
Solution
Stellar Code System re-architected the platform into Kubernetes-based microservices supported by event-driven workflows to improve performance, reliability, and infrastructure efficiency.
1. Microservices Modernization
Decomposed the monolith into Kubernetes-managed microservices
Improved service isolation for scale and maintainability
Reduced dependency bottlenecks across critical workflows
Created a more flexible platform for ongoing product evolution
2. Event-Driven Reporting Architecture
Introduced event-driven architecture for analytics workflows
Improved speed of data movement and reporting execution
Reduced delays in time-sensitive reporting pipelines
Built a stronger foundation for asynchronous processing at scale
3. Reliability and Infrastructure Optimization
Improved uptime through better service orchestration and resilience
Optimized infrastructure usage for lower cost efficiency
Reduced waste from inefficient monolithic scaling patterns
Created a more sustainable operating model for long-term growth
Technology Stack
