Itaú Unibanco Boosts Digital Platform with MySQL Enterprise Edition
for High Availability and Support

"Our digital payment system is a totally new mobile experience for which we needed an infrastructure that provides customers with fast response and maximum security. MySQL Enterprise Edition allows us to make ultra-rapid changes and improvements in real time. Before, we were a cruise ship – with MySQL we are now on jet skis!"

Itaú Unibanco is Brazil's largest private bank and the largest financial institution in Latin America. Currently, 73% of all Itau Unibanco transactions are conducted through digital channels, where 50% are done through smartphones. The bank's objective is to become an increasingly digitized institution in the next years.

Itaú Unibanco runs an Oracle-based core-banking infrastructure. MySQL is one of the databases behind the bank's mobile payments platform as well as for ATM and branch bank monitoring, loans, debt renegotiations, and other services.

To benefit from the high availability features and 24/7 support available with MySQL Enterprise Edition has made Itaú Unibanco decide to migrate its workloads from MySQL Community Edition.

Business Challenges & Goals

  • Adopt a high-performance database layer for multiple banking applications, scalable to millions of users with maximum availability.
  • Ensure fail-safe security for digital wallet credentials to grow the mobile payments customer base.
  • Strengthen back-up and restore capabilities for minimum downtime of business-critical applications.
  • Gain peace of mind through the Oracle 24/7 support available with MySQL Enterprise Edition.

Business Results & Metrics

  • Guaranteed maximum security for millions of digital wallets by storing and handling online payment metadata in MySQL Enterprise Edition 8.0.
  • Accelerated time-to-market through partnering with Oracle Premier Support solutions engineers and product managers for smooth implementation and configuration of new banking apps.
  • Increased mobile payments platform performance by switching from the previous mysqldump to the hot, online, enterprise-grade backup and recovery power of MySQL Enterprise Backup.
  • Optimized performance and availability of applications, including mobile ITI payment platform, ATM monitoring, branch monitoring, loans and debt renegotiation with the real-time visibility provided by MySQL Enterprise Monitor.
  • Reinforced performance and scalability of mission-critical applications through the replication architecture of MySQL Cluster, ensuring resilience to failures and the ability to perform scheduled maintenance without downtime.
  • Opted to deploy MySQL Enterprise Edition, for all new business-critical applications to leverage the proven high availability, scalability, and security of the database.

Why MySQL Enterprise Edition?

While running a mix of databases including other open source products and Oracle 12c, Itaú Unibanco decided to use MySQL Enterprise Edition for all critical applications due to its high availability and security, the premium support, and the smooth migration to the cloud. Currently the bank runs 75 database instances of MySQL Enterprise Edition.

"Oracle Premier Support helped us with implementation and configuration, upgrade to MySQL Enterprise Edition 8.0 and is constantly proactive, solving problems we did not know existed. The team's fast time to resolution, and proactive advice and recommendations really make our eyes shine. This support is a godsend."
