WHY CONTAINERS REQUIRE PERSISTENT STORAGE

• Web & presentation layers should be stateless ... but ...• That’s probably < 5% of all application instances in a DC• Most other infrastructure applications / services require persistence for

storing application and configuration data• Building a different infrastructure for stateful vs. stateless apps ?• Modern IT requires Standardization (e.g. Cloud Computing)• Software-defined DC is a hybrid cloud enabler

REQUIREMENTS FOR CONTAINER STORAGE

• Scalable – Scale out capacity & performance• Resilient – Likely there will be important data• Flexible – Allow different application access profiles• Software-defined – To allow flexible deployment models• Open – For customer choice and lowest TCO

RED HATSTORAGE

PERSISTENT STORAGE REQUIRES REDUNDANCY

• Red Hat Storage includes important data redundancy features• 2-way and 3-way replication• Erasure Coding• Geo-Replication• Snapshots
