Success Stories

Telecom Provider Cost Optimization

AWS RDS Cost Optimization

Upon investigating their AWS RDS setup, we discovered that the company was utilizing nine databases across production and non-production environments. We analyzed usage patterns and current costs, identifying opportunities to switch the storage type from IO1 to the newer GP3, which offered IOPS at no additional cost. Additionally, we recognized that high-cost instances were being used unnecessarily, so we recommended scaling the instances up during peak hours and down during off-peak periods. These optimizations resulted in a savings of approximately $560,000 over the course of one year.

Elasticsearch (ES) Cost Optimization

Next, we turned our attention to optimizing the AWS ES services. Our investigation revealed that the expensive instances used for both data and master nodes were not necessary. We recommended switching to more cost-effective instance types. Furthermore, after a deeper performance analysis, we advised reducing the number of data nodes by a third from the current configuration. These changes led to additional savings of $470,000 across all environments.

Total savings

In total, our cost optimization efforts saved the telecom provider $1,030,000 annually. with plans to save more than $2,000,000 in the coming year.

USA Telecommunications System Enhancement

USA telecommunications system could barely handle 20,000 orders in 15 minutes.
After an elaborate performance testing and tuning effort for 3 years, the project now easily handles 130,000 orders in 15 minutes and withstands new product launches without issues, unlike competitors.
Optimizations included: DB settings, caching strategies, infrastructure changes (VM vs. k8s), server types, middleware settings, and debugging application code.
The system's resilience is now leveraged by the client's cloud provider to test new service features.
Additionally, client expenses on infrastructure were reduced while improving performance.
The project continues with the client maintaining a dedicated performance engineering team to ensure reliability on a sprint-by-sprint basis.

Telecom Provider Performance Testing

Another project for the same telecom provider required performance validation against their expectations and SLAs three months before go-live.
Initially hindered by unfinished performance tests, our team successfully wrote and executed the tests within a month, scaled the infrastructure, and identified critical external dependencies, ensuring readiness for the live deployment without noticeable performance issues.

Estonian Healthcare System Development

The Estonian healthcare system project, approaching a critical live deployment phase, engaged our team to validate performance.
We identified a severe bottleneck affecting multi-user functionality and redesigned the application architecture, thereby avoiding a potential delay in the go-live schedule.
The client appreciated the proactive performance testing approach.

National Healthcare System Reporting Enhancement

Significant issues in the reporting module of a national healthcare system, causing report generation to last days, were addressed by our team.
Through database and SQL optimizations, report generation time was reduced to minutes, greatly exceeding the client's expectations.

Post Service System Performance Fix

A national post's self-service system was facing performance declines in a multi-user environment due to a bug in Spring's cache management.
Our reimplementation of the affected class resolved the issue promptly, allowing the system to go live without performance compromises.

German E-Documents Exchange Platform

Set to go live in one month, this platform required urgent performance validations.
Our team's testing and analysis identified and addressed multiple issues across the system's stack, maintaining the schedule and client satisfaction.

Lithuanian IT Services Provider

A Lithuanian-based international IT service provider was experiencing poor performance in their core utilities.
Our comprehensive system analysis highlighted true performance bottlenecks and disproved suspected ones, guiding the client toward informed system enhancements.

Metaverse Project Optimization

A recent Metaverse project highlights our commitment to efficiency and cost savings without compromising user experience. Initially, the project faced over-scaled resources relative to the current load and needs, leading to exorbitant costs on Google Cloud.
Over the course of one to two months, our team meticulously reviewed the resource allocation and database tuning. Through targeted optimizations, we successfully reduced the monthly expenses from €36,000 to €6,000. This significant cost reduction was achieved while maintaining a seamless user experience, proving our expertise in balancing performance with cost efficiency.
