Infrastructure Modernization

Overview

Managed the provisioning, deployment, and migration of thousands of database instances and application servers across all environments at Ally Financial, systematically retiring legacy infrastructure that posed operational and compliance risks.

Challenge

The bank's infrastructure included aging technologies — Oracle databases, HP servers, Solaris systems, Windows Server 2008, and WebLogic — that created mounting operational risk, compliance exposure, and maintenance costs. Configuration changes across firewalls, storage, network, and servers required careful coordination with multiple teams.

Approach

Coordinated with DBAs and application teams to systematically provision, migrate, and decommission infrastructure across all environments. Managed a high volume of configuration changes while maintaining system stability.

• Provisioned, deployed, and migrated 1,000s of DB instances and application servers
• Managed 25+ system configuration changes per week: firewall, storage, network (F5, DNS), server builds, access, cutovers, and decommissions
• Owned technical debt backlog for retiring Oracle DBs, HP servers, Solaris, Win2008, and WebLogic
• Coordinated across DBA teams, network teams, and application owners

Key Results

• Legacy technologies systematically retired across the enterprise
• Reduced operational risk and compliance exposure from outdated systems
• Sustained high-volume change execution without service disruption

Technical Details

Infrastructure modernization spanned database, server, and network layers. Each migration required coordination with multiple teams and careful cutover planning to minimize business impact.
