The Challenge

The client faced mis-managed workload distribution across 9 AWS accounts, manual and inconsistent patching, reliance on SSH keys, lack of centralized logging, and no visibility into compliance or performance metrics. The absence of AWS Control Tower further led to governance and compliance gaps across their infrastructure.

• Segregated client workloads into dedicated accounts based on compliance requirements.
• Migrated 112 servers (Linux/Windows) with zero downtime during cross-account migration.
• Automated patching processes using AWS Systems Manager Patch Manager.
• Replaced SSH keys with AWS Session Manager for secure, auditable server access.
• Established centralized logging and auditing with AWS CloudTrail for compliance.
• Integrated Amazon CloudWatch for real-time performance monitoring and resource optimization.
• Configured C-panel functionality in the new multi-account environment.
• Delivered secure, scalable infrastructure with automated monitoring and improved efficiency.

The Results

The client achieved a secure, scalable, and compliant AWS environment with 80% faster patching, 100% security compliance, and 60% reduction in management overhead.
