Building a Scalable SQL Server Infrastructure for a SaaS Team

Client Challenge:

The client required a robust and efficient database infrastructure to support their newly established SaaS team. The existing environment consisted of over 20TB of data spread across mixed Oracle 10g and SQL Server 2000-2008 systems. They needed a seamless migration to a unified, optimized structure that adhered to stringent audit requirements while maintaining 24/7 operations.

My Role:

As the primary Database Administrator, I led the design, implementation, and documentation of a sustainable SQL Server database infrastructure, provided production and development support, and ensured adherence to best practices and compliance standards.

Key Achievements:

Cluster Implementation: Designed and deployed a two-node SQL Server 2008 R2 failover cluster on Dell/EMC CX4-480 SAN, accommodating 10TB of data and scaling to handle over 16TB.
Massive Data Migration: Developed and executed custom T-SQL scripts to migrate more than 5,400 production databases from disparate systems (SQL Server 2005/2008/Oracle 10g) to the new production clusters, ensuring a smooth transition.
Audit-Ready Security: Implemented audit-compliant security measures on all new SQL Server production instances, establishing a foundation of trust and compliance.
Standardized Backup Strategy: Deployed a uniform backup solution using Quest LiteSpeed, ensuring consistent and reliable data protection.
Proactive Monitoring: Introduced proactive server monitoring using Idera SQL Diagnostic Manager, minimizing downtime and optimizing performance.

Results:

The newly implemented infrastructure supported the SaaS team with a scalable and efficient database environment, significantly reducing operational risks and improving data accessibility. The migration was completed without major disruptions, and the system was prepared for upcoming audits, meeting all compliance requirements.

Value Delivered:

By consolidating and optimizing the database environment, the client achieved:

Increased reliability and scalability for future business growth.
Significant operational cost savings through streamlined processes and improved resource utilization.
Enhanced audit readiness and data security.
