• SQL Server security: Authentication modes, TDE, column-level encryption, auditing
• Performance Tuning: Query optimization, index management, wait statistics, execution plans, DMVs
• T-SQL – Expert-level scripting for database administration, migration validation, and automation
• SSIS, SSRS, SSAS – Compatibility assessment and migration considerations

Amazon RDS for SQL Server

• RDS SQL Server deployment: Instance class selection, storage configuration, parameter/option groups
• RDS Multi-AZ: Synchronous replication, automatic failover, maintenance windows
• RDS cross-region read replicas: Configuration, promotion, replication lag monitoring

Database Migration Tools & Techniques

• **AWS DMS –**Source/target endpoint configuration, replication instances, CDC (Change Data Capture)
• **AWS SCT –**Assessment reports, schema conversion, code migration
• **Native SQL Server methods –**Backup/restore to RDS, log shipping, transactional replication
• **DMAF –**Database Migration Assessment Framework for planning

IaC & Testing

• Terraform or CloudFormation – RDS instance provisioning, parameter group management across two regions
• Database migration testing: Record count validation, data comparison, performance benchmarking
• Cutover planning and rollback procedure development and testing
• Interim architecture planning for workloads migrated on varying schedules

Required Certifications

• AWS Certified Database – Specialty (highly preferred)
• AWS Certified Solutions Architect – Associate (minimum)
• Microsoft certifications in SQL Server administration or development (beneficial)
