From Vision to Impact, RDB’s Proven Track Record.
Case Study 1
Financial Services – Maximising Uptime
Maximising Uptime for a Major Bank through Remote DBA Support
Client Profile: A large South African commercial bank with a complex, heterogeneous database environment (Oracle and SQL Server) supporting core banking applications.
The Challenge: The bank faced high staff turnover in its DBA team, leading to inconsistent maintenance, slow performance, and a high risk of unplanned downtime. They needed a reliable, 24/7 solution that could eliminate the single-resource risk.
RDB Consulting Solution: We implemented our full Database Managed Services model, providing Remote DBA support for their entire environment. This included:
- Deployment of our proprietary Proactive database monitoring system.
- Implementation of a new, automated Backup and disaster recovery strategy.
Ongoing DB performance tuning to resolve persistent bottlenecks.
The Result: The bank achieved a 99.99% uptime record over two years, eliminating all unplanned database-related downtime. The cost of the managed service was significantly lower than the cost of maintaining a full in-house team, resulting in substantial cost savings and complete elimination of the skills risk.
Case Study 2
Mining Sector – Cloud Migration
Seamless Cloud Migration for a Global Mining Company
Client Profile: A global mining company operating across multiple continents, looking to modernise its legacy on-premise ERP and data warehouse systems.
The Challenge: The company needed to migrate its massive Oracle data warehouse to the cloud to improve scalability and reduce infrastructure costs, but lacked the internal expertise for a complex, large-scale Cloud migration consulting project.
RDB Consulting Solution: We provided end-to-end Cloud migration consulting, focusing on a phased migration to AWS migration support.
Phase 1: Strategic planning and architecture design for a Hybrid cloud solutions model.
Phase 2: Execution of a zero-downtime Platform & Data Migrations of the Oracle data warehouse to Amazon RDS.
Phase 3: Post-migration optimisation and ongoing Remote DBA support for the cloud environment.
The Result: The migration was completed ahead of schedule with zero disruption to operations. The company reduced its annual infrastructure costs by 30% and gained the scalability required for its global operations.
Case Study 3
Retail – Performance Tuning
Resolving Peak-Season Performance Issues for a Major Retailer
Client Profile: A major national retailer whose e-commerce platform experienced severe slowdowns during peak sales periods.
The Challenge: The retailer’s in-house team could not identify the root cause of the performance degradation, which was costing millions in lost sales during critical trading hours.
RDB Consulting Solution: We deployed a specialised team for a targeted DB performance tuning engagement.
- We identified several poorly written SQL queries and an inefficient indexing strategy.
- We optimised the database instance parameters and implemented a new caching layer.
- We provided training to the in-house development team on best practices for database interaction.
The Result: The e-commerce platform’s transaction processing speed increased by 40% during peak load testing. The retailer successfully navigated the next peak sales season with zero performance-related issues, directly translating to increased revenue.
Case Study 4
Government – Risk and Compliance
Ensuring Data Security and Compliance for a Government Agency
Client Profile: A national government agency responsible for managing sensitive citizen data.
The Challenge: The agency required a comprehensive security audit and a robust Database Risk Management strategy to comply with new data protection regulations (similar to POPI/GDPR).
RDB Consulting Solution: We conducted a full 20-point database audit and implemented a comprehensive risk mitigation strategy.
Implementation of advanced Database security services, including fine-grained access control and enhanced user security management.
Develop and document a new Backup and disaster recovery plan.
Deployment of continuous auditing and reporting mechanisms to ensure ongoing compliance.
The Result: The agency successfully passed its external compliance audit and significantly reduced its exposure to data breach risks, ensuring the security and integrity of citizen data.
Case Study 5
Technology – Co-Sourcing
Bridging the Skills Gap with Co-Sourcing for a Technology Firm
Client Profile: A fast-growing technology start-up with a small, junior in-house IT team.
The Challenge: The in-house team could handle daily operations, but lacked the senior expertise to manage a critical, planned migration to a Hybrid cloud solutions environment and troubleshoot complex, intermittent performance issues.
RDB Consulting Solution: We implemented a Co-Sourcing Services model.
- The junior in-house team continued with day-to-day tasks.
- RDB provided a senior consultant on a flexible, part-time basis to mentor the in-house team and lead the complex migration project.
- The RDB consultant was available on-demand for critical problem-solving and DB performance tuning.
The Result: The start-up successfully completed its complex migration project on time and within budget. The in-house team’s skills were significantly enhanced through mentorship, and the company gained access to senior expertise without the high cost of a full-time senior hire, achieving significant cost savings.
