The topic of running MongoDB on Amazon Web Services using Elastic Block Storage came up again among the 10 tips for running MongoDB from Engine Yard:
you should know that the performance of Amazon’s Elastic Block Storage (EBS) can be inconsistent.
Following up on that Mahesh P-Subramanya aptly added:
Indeed! I’d actually take it a step further and say Do not use EBS in any environment where reliability and/or performance characteristics of your disk-access are important. Or, to put it differently, asynchronous backups - OK, disk-based databases - Not So Much.
Interestingly though, some presentations earlier this year–MongoDB in the Amazon Cloud and Running MongoDB on the Cloud—left me, and others with the impression that EBS should not be dismissed so fast.
