EXPERIENCES WITH MONGOHQ

I got 99 problems but a schema ain’t one


LIFE IN THE CLOUD

•Hosting MongoDB on a cloud VPS

•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


WHAT TO EXPECT?

•Slave access on Large & Small plans

•Stats and Slow Query Logs

•Dedicated plans with sharding & replica sets

•More AWS regions

•More cloud providers
