Motivation
The client faced frequent performance slowdowns, errors in document handling, and system instability under heavy operational loads in their legacy warehouse management system. Their pain points included delayed order processing, inefficient inventory recalculations, and difficulty maintaining consistent configuration across multiple warehouses. Azati’s goal was to address these issues by modernizing the platform with a fault-tolerant, scalable architecture, automating critical background tasks, and centralizing configuration management to ensure smooth, reliable warehouse operations.
Main challenges
Challenge 01
Migrating to a Modern Architecture
The legacy system could not handle increased workloads, resulting in performance degradation. Azati proposed a microservices-based architecture that enabled fault tolerance, faster data processing, and horizontal scalability, which stabilized the system during intensive operational loads.
#1
Challenge 02
Development of Configuration and Async Task Services
System settings and background tasks, such as inventory recalculation and order processing, had to be processed efficiently without affecting primary operations. Azati developed dedicated microservices to manage configurations and async operations, improving performance and simplifying control of long-running processes.
#2
Challenge 03
Reliable Document Printing Support
Printing labels, reports, and other warehouse documents frequently caused errors and slowdowns in the legacy system. Azati built a robust printing service that automated and streamlined the handling of various document formats and templates, increasing document management efficiency.
#3
Our approach
Building a Microservices-Based Architecture
Azati created a flexible, fault-tolerant system architecture that supports scaling and rapid changes in business logic. This new architecture ensures the stability and speed required for large-scale warehouse operations.
Developing Configuration and Async Task Services
We introduced services that centrally manage system configurations and background operations like stock recalculation and notification handling, boosting responsiveness under peak loads.
Automating Warehouse Document Printing
A standalone print service was built to support high-volume, multi-format document output, increasing reliability and reducing operational delays associated with document handling.
Close Collaboration with Internal and External Teams
Azati worked closely with internal business units to tailor the system to specific warehouse processes, while also coordinating with external teams to ensure seamless integration with other enterprise solutions.

01
Configuration Management Service
A centralized service that allows warehouse administrators to manage rules, thresholds, and settings across all warehouse processes. It ensures consistency, reduces manual errors, and simplifies updates without system downtime.
Key capabilities:
- Centralized storage of system-wide configuration parameters
- Real-time synchronization of configuration changes across services
- Granular control over warehouse rules, thresholds, and business logic
- Simplified maintenance and transparent configuration auditing
02
Asynchronous Task Processing Service
Handles all background operations such as stock recalculations, order processing, and event-driven notifications. This service ensures the main warehouse operations remain responsive and prevents performance degradation during peak workloads.
Key capabilities:
- Execution of long-running operations such as stock recalculation
- Event-driven processing of orders and inventory updates
- Queue-based task distribution for improved load management
- High-performance notification and event processing pipeline
03
Document and Label Printing Service
A robust service that automates the creation, formatting, and printing of warehouse documents and labels. This reduces delays, minimizes printing errors, and supports high-volume operations typical for large retail warehouses.
Key capabilities:
- Automated generation and printing of labels, reports, and forms
- Support for multiple document templates and formats
- Error-resistant handling of print tasks under high load
- Improved print queueing and monitoring tools
04
Scalable Microservices Core
The backbone of the modernized WMS, consisting of independent services that can be deployed, updated, and scaled separately. This architecture ensures fault tolerance, system stability, and flexibility to adapt to future business needs.
Key capabilities:
- Independent deployment and horizontal scaling of modules
- High availability through service isolation and redundancy
- Faster delivery of new features and business logic updates
- Improved resilience during failures and traffic spikes
