It’s Multi Cloud World!
“By running an active-active architecture across
Google Cloud Platform (GCP) and AWS, we’re in a
better position to survive a DNS DDOS attack, a
regional failure — even a global failure of an entire
cloud provider.”
“Multi-cloud deployments would not have been
possible without Spinnaker, and that "Spinnaker
saved us 1,000 people.”
- Nir Tarcic, SRE at Waze

Reasons for going Multi Cloud
Network interruptions: Latency and network unavailability are leading causes of outages.
Infrastructure failure: Data Center Outages. It’s inevitable, and should be assumed.
Business Continuity: Results in revenue loss and developer productivity.
User Experience: Apps and data deployed closer to consumer geographical location provide
better user experience.
DDoS attack: On the rise, these attacks paralyze your apps and suffocate your network.

Why do we need data replication across Geos?
• Data Placement
• Improve latency for end
customers
• High Availability
• Disaster Recovery
• Active/Active
• Business Requirements
• Regulatory compliance

Internet Scale Caching @ Netflix
“The Netflix customer experience relies
heavily on caches to provide a high-
volume, low latency, globally available
data layer that backs our stateless
services.
Throughout a typical customer
experience, from sitting down on the
couch through playing a movie, caches
play a role in every interaction.”

Pivotal Cloud Cache HA and Fault Tolerance
Failing data copies are
replaced transparently
Data is replicated to other
clusters and sites (WAN)
Network segmentations are
identified and fixed automatically
Client and cluster disconnections
are handled gracefully
Data is persisted on local
disk for ultimate durability

Conclusion...
● Multi cloud strategy is real, there are many reasons why customers should
consider them
● PCC is the defacto caching solution on PCF today
● We are first data tile which truly connects multiple PCF foundations. In doing so
we are paving the way for other tiles
● We are looking at ways to enhance Multi cloud experience on the platform as a
first class concept
