3. Linux Containers
Software packaging concept that typically includes an application and all of its runtime dependencies
• Higher Quality Software
Releases
• Shorter Test Cycles
• Easier Application

7. Why Persistent Storage for Containers?
Base: 194 IT operations and development decision-makers at enterprises inAPAC, EMEA, and NorthAmerica

“For which workloads or application use cases have you used/do you anticipate to use containers?”
Scalable, Cost Effective, Distributed Storage for Containers

8. Driving the Future of Storage
• Dedicated storage cluster
for containerized and PaaS
environments
• Supported for OpenShift
Enterprise
RHGS Container
• Containerized Red Hat Gluster Storage
serving storage from a dedicated
storage cluster
• Optimized for applications running on
RHEL 7, OpenShift Enterprise, and
RHEL Atomic Host
• Containerized Red Hat Gluster
Storage inside OpenShift Enterprise
hyper converged with application
containers
• Red Hat Gluster Storage cluster
comprised of disks from multiple
nodes in a container cluster

• LowerTCO
• Unified Orchestration
• Ease of Use
• Greater control

12. BENEFITS
• New agilities allowed telco to bring a new offering to market faster
and cheaper than ever
• Lower cost than traditional storage and avoiding an endless
commitment to proprietary vendors
• Flexible, geo-replicated architecture can
grow and shrink dynamically
• Option to be tuned for price or performance (or a blend)
HYPER CONVERGED STORAGE
• Applications and storage can co-exist on the same hardware
• Allows for higher server utilization and lowers operational costs
• Storage generates only 3%–10% overhead on compute servers
Customer Success

Excellent sharing of services, lower cost of maintenance…
But what if the front desk (kernel) is compromised?
