专家点评

“对于大多数常规工作负载，选择 gp3，因为您可以以低于 gp2 的成本获得 3000 IOPS 的基线性能。对于需要持续的亚毫秒延迟的数据库，io2 Block Express 可提供最高 256000 IOPS，持久性为 99.999%。”

“当多个 EC2 实例或容器需要对同一个文件系统进行并行读/写访问时，EFS 就是解决方案。它会自动增长和收缩，因此您永远不必预置容量或担心耗尽空间。”

What's the difference between Amazon RDS and Amazon Redshift?

Both run SQL queries, but they're optimized for fundamentally different workloads. RDS handles transactional operations (inserts, updates, lookups) for your application. Redshift handles analytical queries (aggregations, scans, joins across billions of rows) for your data team.
