Intensive workloads that require less IOPS but high throughput. Throughput Optimized HDD volumes (st1) offers low-cost HDD volume designed for Performance level and the better it performs when more performance is needed. More credits your volume has for I/O, the more time it can burst beyond its base I/O credits represent the available bandwidth that your General Purpose (SSD) volumeĬan use to burst large amounts of I/O when more than the base performance is needed. Larger volumes have higher base performance levels and accumulate I/O credits faster. The base performance level of the volume and how quickly it accumulates I/O credits. General Purpose (SSD) volume performance is governed by volume size, which dictates Size and the number of queries being executed. Needed from the database varies many times during a period of time based on the load This works very well for most database workloads because the IOPS performance
GP2 volumes can vary from a baseline IOPS up to a maximum burstable 3,000 IOPS per Similar to PIOPS volumes, GP2 volumes are also SSD-based, but the IOPS you get from
For example, to get 3,000 IOPS your volume size should be at least 100 GB. The ratio of IOPS provisioned to the volume size requested can be a maximum Provide, PIOPS volumes are the right choice.įor PIOPS volumes, you specify an IOPS rate when you create the volume, and Amazon EBS delivers within 10% of the Provisioned IOPS performance 99.9% of the time over a When your database requires higher IOPS than what GP2 can GP2 volumes provide an excellent balance of price and performanceįor most database needs. Refer to Amazon RDS DB instance storage for the latest limits of IOPS per volume for both GP2 and PIOPS volume types. GP2 and PIOPS volumesĪre available for both Amazon EC2 and Amazon RDS. General Purpose (GP2) volumes or Provisioned IOPS (PIOPS) volumes. High-performance architectures, you can use instance storage SSDs, but they should beĪugmented with Amazon EBS storage for reliable persistence.įor high and consistent IOPS and database performance, AWS highly recommends using
The decision might be easy if your DBA's already have established, proven procedures to meet all of your requirements.Most users typically use Amazon EBS for database storage. However, if your organization has strong DBA skills and a thin Sys Admin team, you might be better off with a database. If what you have is adequate for your current and projected needs, you can't beat the simplicity of a file system. Technically, there's a file system/OS based solution for each of the points I listed (eg, rsync, kernel level audting, file system encryption). Provide you with a record of who has accessed each file.ĭata Privacy: is encrypting data in your database of choice easier Logging/Auditing: security features of most modern databases should You with backup options (log assisted backup, snap shots, consistent

Putting the pain of switching aside, here are some things to consider:ĭata Consistency: you didn't specify what file system/platform you're Is there anything broken or cumbersome about your current storage scheme? The transition cost of moving your files into a database will be nontrivial.
