EXPERIENCES WITH
MONGOHQ
I got 99 problems but a schema ain’t one

LIFE INTHE CLOUD
•Hosting MongoDB on a cloudVPS
•Some lessons learned as a hosting provider
•What to expect from MongoHQ in the future

DISK I/O IS NOT WEB SCALE

DISK I/O IS NOT WEB SCALE
• Virtualized I/O is variable
• File allocation can be slow
• EBS RAID is better

EBS RAID
•RAID-0
•Much faster
•Harder to snapshot

SNAPSHOTTING RAID
•Snapshot queues
•Can’t be synchronized
•SLOW

SNAPSHOT ALTERNATIVES
•Multiple Slaves with --slavedelay
•Same beneﬁts*
•faster / easier recovery
•always consistent

FREEMIUM UNLEADED
•NOT for production
•lowers barrier
•customers ﬁrst experience
•higher volatility
Free Micro Small Large

QUOTAS
•Weak implementation
•File based rather than size based
•Strange things happen when you approach it

32-BIT ENVIRONMENT
•Don’t do it
•Under any circumstance
•Seriously

BLEEDING EDGE ... IT HURTS
•MongoDB
•Drivers
•ODMs
•Plugins

WHATTO EXPECT?
•Slave access on Large & Small plans
•Stats and Slow Query Logs
•Dedicated plans with sharding & replica sets
•More AWS regions
•More cloud providers
