SQL databases are not built for the cloud.
Bottleneck
Doesn‘t scale
Single point of failure
Adding new Replicas
Consistent backups
Recovery times after crashes
Database(Choose wisely)

Comparision

Availability: Each client can always read and write
Consistency: All clients always get
the same data
Partition Tolerance: System works despite
network splits

DynamoDBCassandraSimpleDBCouchDBRiak
RDBMS(MySQL, Oracle, …)
MongoDB,Redis,Bigtable
NoSQL - So many choices …
MongoDB
Riak
CouchDB
BigCouch

Cassandra
… remember that you have to run all of these on EBS :-(
MongoDB
Advantages
Auto-Sharding
Good performance
Dynamic query interface
Disadvantages
Global Write-Lock
No automatic rebalancing, Master-Slave-Replicationw/ Auto Failover
Redis
Advantages
Performance (in-memory)
Transactions
Disadvantages
Only Master-Slave-Replication
Limited by memory
Cassandra
Advantages
Automatic Replication and Rebalancing (N,R,W)
Secondary Indices
Disadvantages
Writes are faster than reads
Bad scaling for 2nd indexes
Super-complex to handle
Riak
Advantages
Automatic Replication and Rebalancing (N,R,W)
Secondary Indices
Large Blobs
Map/Reduce
Disadvantages
InnoDB Backend, slow writes
CouchDB
Advantages
Bidirectional replication
Crash Only-Design
Changes Feed
Views via JS Map Reduce
Disadvantages
Serialized Writes
Sharding/Rebalancing only with BigCouch
Our History
We started with Bigcouch
Switched to CouchDB
