Our Success Stories

Real-world transformations — from legacy systems to modern, high-performance data platforms. See how we've helped businesses like yours achieve breakthrough results.

Legacy Oracle to AWS RDS — Zero Downtime Migration

Challenge

FinCorp's on-premise Oracle 11g database was struggling with peak-hour performance, high maintenance costs, and limited scalability. A critical merger demanded a modern, cloud-native foundation.

Solution

Yagna Software executed a phased migration to AWS RDS for Oracle using Oracle GoldenGate for real‑time replication, ensuring zero downtime. We optimized schemas, re‑architected indexes, and automated failover.

Result

55% lower TCO · 99.99% availability · query speed improved by 4.2x

HIPAA‑Compliant MongoDB Atlas for Patient Records

Challenge

HealthLink's legacy MSSQL database couldn't handle the velocity of IoT data from wearable devices. Strict HIPAA compliance and real‑time analytics were non‑negotiable.

Solution

We designed a secure MongoDB Atlas cluster with field‑level encryption, VPC peering, and automated backup. Built a change‑data‑capture pipeline to stream patient vitals into a real‑time dashboard.

Result

100% HIPAA compliance · 300% faster writes · 99.999% durability

Real‑Time Inventory with TiDB & HTAP

Challenge

RetailTech's MySQL sharding broke during flash sales. They needed a distributed database that could handle millions of concurrent reads/writes while running real‑time analytics on the same data.

Solution

We migrated to TiDB, a distributed HTAP database, with TiFlash for real‑time analytics. Implemented auto‑scaling, cross‑AZ replication, and a custom caching layer with Redis.

Result

0 downtime during peak sales · 68% faster inventory sync · 40% cost savings

Cassandra for Smart‑Grid Sensor Data

Challenge

EnergyNova's PostgreSQL instance was overwhelmed by 50,000+ sensor writes per second from smart meters. Data retention and query latency were spiraling out of control.

Solution

We deployed a 12‑node Cassandra cluster with a custom data model optimized for time‑series queries. Built a data pipeline using Kafka and Spark for real‑time anomaly detection.

Result

1.2M writes/sec sustained · 80% lower latency · 5-year data retention

Oracle Exadata Modernization & GoldenGate Replication

Challenge

GlobalLogistics ran a critical Oracle Exadata X5 system with growing storage bottlenecks and high licensing costs. They needed a hybrid cloud strategy to extend capacity without sacrificing performance.

Solution

Yagna Software implemented Oracle GoldenGate bidirectional replication between on‑prem Exadata and AWS RDS. Upgraded to Exadata X9M with HCC compression, cutting storage footprint by 60%.

Result

60% storage reduction · 3x faster queries · $2.1M annual savings

ClickHouse & Snowflake for Petabyte‑Scale Analytics

Challenge

AnalytixInsight's data lake on S3 was too slow for interactive dashboards. Their legacy Redshift cluster couldn't scale cost‑effectively for ad‑hoc queries from 200+ data scientists.

Solution

We architected a tiered analytics platform: ClickHouse for real‑time ingestion and fast aggregations, Snowflake for ad‑hoc SQL and data sharing, with dbt for transformation pipelines.

Result

100x faster dashboards · 70% lower query cost · 10TB processed daily
