With the cost to store data approaching zero......we're ending up with digital Hoarders™.
JUST BECAUSE YOU CAN DOESN’T MEAN YOU SHOULD

If we stored all of the global data as “an average” enterprise..
..it would take....38.5% of the World GDP!
EFFICIENT STORAGE IS KEY

WORLD GDP $5.13 TRILLION
COST TO STORE A ZETTABYTE $1.98 TRILLION

THE OPPORTUNITY
MOST DATA IS AT REST
STORAGE I/O IS EXPENSIVE
ADVANCED FEATURES ARE EXPENSIVE
USE HYBRID DATA STORAGE
MAXIMIZE BENEFITS

OBJECT STORAGE
Distributed, REST-based API, No central database
Hardware agnostic - commodity hardware, RAID not required
Account/Container/Object structure (not file system, no nesting)
Replication (N copies of accounts, containers, objects)
Data distributed evenly throughout system
Scalable to multiple petabytes, billions of objects
