💡 Database Sizing Best Practices

  • Plan for growth: Always size for 12-24 months ahead to avoid frequent migrations
  • Memory is key: More RAM = better performance. Aim to fit working set in memory
  • IOPS matters: Ensure sufficient IOPS for your query workload, especially for OLTP
  • Monitor and adjust: Use monitoring tools to track actual usage and optimize
  • Consider replication: Add read replicas for read-heavy workloads
  • Backup storage: Plan for 2x your data size for backups and snapshots
  • Start smaller: You can always scale up; starting too big wastes money
