What challenges did California Credit Union face with its disaster recovery?

California Credit Union implemented AWS services for second-level backup of their Fiserv DNA core banking system by migrating from VMware to Amazon EC2 for compute resources, using Amazon EBS for high-performance local storage, and Amazon S3 for backup storage. This transition allowed them to run a test instance of Fiserv DNA on AWS and conduct successful disaster recovery tests.
What future plans does California Credit Union have for its AWS implementation?
California Credit Union is exploring enhancements to their AWS implementation, including the potential for active-active configurations for systems that support it and extending the duration of AWS-based operations during failover tests. They aim to continue improving their operational resilience and set the stage for future innovations in financial services.
