  • Monitor and optimize resource utilization (CPU, memory, storage) for both EDB PostgreSQL and MySQL.
  • Troubleshoot and resolve performance bottlenecks and database-related application issues.
• Backup and Recovery:
  • Implement robust backup strategies, including full, incremental, and point-in-time backups.
  • Plan and perform database recovery operations to ensure minimal data loss.
  • Use tools such as pgBackRest, WAL archiving, MySQL dump, and physical and logical backup techniques.
• Replication and Clustering:
  • Set up and maintain replication (e.g., streaming replication, logical replication) and clustering solutions.
  • Configure and manage failover solutions to enhance database resilience and availability.
  • Administer and troubleshoot EDB Postgres Advanced Server tools like EFM (EDB Failover Manager), PG Pool, and PG Bouncer.
• Database Security and Compliance:
  • Implement security best practices, including role-based access control and encryption.
  • Ensure compliance with regulatory and security standards.
  • Manage user access and permissions securely.
• Database Cloud Migration:
  • Lead cloud migration projects to AWS, GCP, or Azure.
  • Design and implement strategies for minimal-downtime migrations.
  • Leverage cloud-native features to optimize performance and scalability.
