Differences between Public Cloud and Private Cloud
Private cloud offers more fine grained control over the infrastructure as compared to Public Cloud

Service Security Policy
Leverage Smart NICs to program security policies to deliver performance & scalability
Service Operational Policy
Leverage Host and Resource Cluster near-real-time resource metrics and real-time faults & alerts to substantially improve closed loop remediation response time
Service Placement Policy
Leverage Resource Cluster near-real-time allocated resource capacity and metrics/faults/alerts to substantially improve dynamic workload placement/scheduling across cloud regions
These can be represented as additional soft constraints in the placement/scheduling minimize/maximize objective function
Appendix A
Resource Cluster Group Usage Example
VNF Type- EPC CP, PGW DP, SGW DP, BNG DP, IMS CP, etc. – where CP is Control Plane and DP is Data Plane
Resource Cluster A - “RCA” - hosts with standard NICs
Resource Cluster B - “RCB” - hosts with IPSec offload NICs
Resource Cluster Group A - “RCGA” - “RCA” and “RCB”
Resource Cluster Group B - “RCGB” - “RCB”
Resource Slice A - “RSA” - logical slice in “RCGA”
Resource Slice B- “RSB”- logical slice in “RCGB”
Resource Slice C- “RSC”- logical slice in “RCGB”
Realizing Minimum guarantees
Sum of minimum guarantees of resource slices cannot exceed the total capacity of the resource clusters they belong to
Placement Policy Example
VNF Type “EPC CP” uses “RSA”
NIC offloads are immaterial to EPC CP; EPC CP can use “RCA” and “RCB”
VNF Type “PGW DP” uses “RSB”
IPSec offload in NIC is a must for PGW DP performance reasons
