Introduction

Investment Bank, a leading financial institution, faced critical challenges related to database backup, recovery, and disaster management. With a substantial client base and complex financial transactions, the bank relied heavily on its Oracle and MySQL databases. Investment Bank looked for a strong solution because the database services were often interrupted, and there were worries about the accuracy of the data.

 

Challenges:

⦿ Downtime Impact: Frequent downtimes in both Oracle and MySQL databases were impacting critical financial transactions, resulting in potential revenue loss and reputational damage.
⦿ Data Security Concerns: The bank, dealing with sensitive financial information, was particularly concerned about data security during backup, recovery, and in the event of a disaster. Following industry regulations was a top priority.
⦿ Inefficient Backup and Recovery Procedures: Existing backup and recovery processes were timeconsuming; it took longer to get everything working again. This slowness made it more likely that things would stay broken for a while.
⦿ Scalability Issues: As the bank’s operations expanded, the existing database infrastructure struggled to scale efficiently, impacting overall performance.
⦿ Disaster Management Plan: The absence of a robust disaster management plan increased the weakness of the bank’s databases, raising the risk of data loss in the face of unexpected events occurrences.

 

AWS Solution Proposed by Teleglobal:
Migration to Amazon RDS:
⦿ Teleglobal recommended migrating both Oracle and MySQL databases to Amazon RDS for seamless management, scalability, and high availability.
⦿ Using Amazon RDS allows for automatic backups, reducing manual effort for routine tasks.

Disaster Recovery on AWS:

⦿ Utilized AWS Multi-AZ deployments for Oracle and MySQL to ensure data redundancy and high availability.

Enhanced Security Measures:
⦿ Implemented AWS Key Management Service (KMS) for strong encryption of data at rest and in transit.
⦿ Enabled Virtual Private Cloud (VPC) for network isolation, improving overall security.

Automated Backup and Recovery:
⦿ Configured automated backup schedules and streamlined recovery processes using AWS tools.
⦿ Utilized Amazon S3 for cost-effective and efficient storage of backups.

Scalability with AWS Services:
⦿ Used AWS Auto Scaling to help the system grow when needed, ensuring databases can manage more transactions as the business grows.

 

Business Impact / Benefits:

⦿ Reduced Downtime: The bank experienced a significant reduction in downtime, ensuring uninterrupted financial transactions and improving overall customer satisfaction.
⦿ Enhanced Security and Compliance: With strong encryption and AWS certifications, Investment Bank met industry standards, ensuring data security and following regulations.
⦿ Improved Operational Efficiency: Automated backup and recovery processes streamlined operations, reducing the time required for database maintenance.
⦿ Scalability for Future Growth: The scalable architecture allowed the bank to manage growing business demands without impacting performance.
⦿ Complete Disaster Management: The implemented disaster recovery plan provided a backup plan, reducing dangers associated with data loss and ensuring quick recovery in case of unexpected events.

 

Disaster Event: Logical Error in Oracle Database (Error Code: ORA-08103)

The Challenge:

⦿ In the case of a logical error in the Oracle database, The Investment Bank and Teleglobal worked together efficiently to swiftly resolve the issue.

1. Identifying the Disaster:
The Oracle DBA detects a logical error that requires immediate attention to prevent any further complications.
