How Capital One migrated 32 Sybase servers to AWS with near-zero downtime
Capital One operated one of the largest Sybase deployments in U.S. financial services, a sprawling estate of 24 ASE database servers and 8 Replication Server instances handling mission-critical transactional workloads, plus a Sybase IQ data warehouse serving regulatory reporting and business intelligence.
Aging infrastructure, rising licensing costs, and limited cloud elasticity made modernization urgent. But as a top-10 U.S. bank, zero tolerance for production disruption made the migration exceptionally high-stakes.
How ExxonMobil eliminated Oracle Exadata and migrated its data center to AWS
ExxonMobil operated a significant Oracle Exadata estate carrying some of the highest total cost of ownership in enterprise infrastructure. Licensing, maintenance, and hardware refresh cycles had become a substantial cost center with limited cloud elasticity.
The opportunity was clear: retire Exadata, migrate all associated databases to AWS, and exit owned data center infrastructure entirely without impacting the operational systems running one of the world's largest energy companies.
How Itaú Unibanco migrated 400+ SQL Server Databases to AWS at enterprise scale
Itaú Unibanco operates at extraordinary scale, serving over 60 million customers across Brazil and 20 countries. Its core banking infrastructure relied on a vast estate of 400+ Microsoft SQL Server databases spread across on-premise data centers, carrying significant licensing overhead and growing operational complexity.
The mandate was clear: migrate everything to AWS with minimal disruption to 24/7 banking operations, maintain strict compliance with Brazil's LGPD and BACEN regulatory requirements, and position the platform for long-term cloud-native growth.
How Hilton optimized 4,000+ Aurora MySQL instances for performance, availability & DevOps
Hilton operates one of the most demanding AWS database estates in the hospitality industry, 4,000+ Amazon Aurora MySQL instances powering reservations, loyalty programs, property management, and guest experiences across 7,500+ hotels in 126 countries.
At that scale, recurring incidents, version drift, and error-prone schema deployments created measurable operational risk where downtime is non-negotiable. Hilton needed a partner to reduce incidents, harden availability, automate fleet-wide upgrades, and eliminate deployment fragility through Flyway.
