Scale Db Preso For Boston My Sql Meetup (9/2009)

ScaleDB
The cloud database
Dial 712-338-7116
Access Code: 789-140-794

The Problem
The cloud enables you to provision storage and compute power, but not database services…until now.
ScaleDB “cloud-enables” open source databases, making them dramatically easier to provision, manage, scale and maintain in the cloud.

The Cloud is Disrupting Databases

Customer Value Proposition
Runs on low-cost cloud infrastructures (e.g. Amazon)
High-availability
Dramatically easier set-up & maintenance
No partitioning/repartitioning
No slave and replication headaches
Simplified tuning
Scales up/down without interrupting your application
Data consistency
Lower TCO

Cloud Vendor Value Proposition
Supports Service Level Agreements
High-availability (less downtime, faster recovery)
Shifts relationship from dedicated hardware to SLA = profits
Compatible with Virtualization (separates data/computing)
More portable across computing infrastructure
Enables dynamic allocation of computing and storage
Reduces Management Overhead
Reduced tuning and partitioning support
No manual slave promotion or replication
DBMS request routing is dynamic not fixed
