Cloud Computing - Introduction
Cloud Service
Consumer or Tenant
One or more DC
Cloud Service Provider
Network (Internet/Intranet/
Private MAN/WAN)
VM13
DB1 OS1 vNIC2
Cloud Service Interfaces
IaaS: Infrastructure resources
PaaS: Software middleware, development & test resources
SaaS: Application product resources

Cloud Deployment – NIST Definition
Private Cloud: For use by an enterprise only Owned / operated by enterprise IT or 3rd
party
Public Cloud: For use by anyone Owned / operated / offered by a Cloud
Service Provider
Hybrid Cloud: Multiple interoperable Clouds that enables data and application portability Multiple operators

Seamless Hybrid Cloud With Hybrid Cloud enterprises may have
resources distributed in Enterprise intranet and one or more Public Clouds
Enterprise should be able to execute apps on these distributed resources seamlessly as if they are on the intranet
Manage distributed on-premises and off-premises Cloud resources seamlessly with IT resources
Seamless Hybrid Cloud Abstraction, Interfaces and their realization on infrastructure will facilitate above

CLoud Isolation Abstraction: CLIA
Network isolation technology, VLAN, VPN, Tunnel, Routing/Switching [table] isolation: VRF, etc., independent abstraction
CLIA abstracts network isolation for each tenant into one Cloud abstraction

Differentiated Quality of Cloud Services
QoS associated with SCL QoS abstraction: Platinum, Gold, etc.
applied in aggregate QoS abstraction defined based on
Application Classes as defined in RFC 4594 Example: Multimedia Conferencing
Loss/Delay/Jitter bound: .001/100ms/50ms
DiffServ (DSCP) marking: AF41/42/43

Conclusion
SCL and CLIA abstractions and their realization … Allows secure and seamless integration of tenant’s
enterprise to Public Cloud Simplifies Cloud usage by tenants Allows CSP offer sophisticated SP & Enterprise
grade Cloud services Allows seamless execution of applications on
resources distributed over Clouds together with enterprise resident resources
Allows seamless management of Cloud resources together with enterprise IT resources

Further Work Abstraction realization in network via network management
systems
CLIA realization via PPVPN (Provider Provided VPN) extension to support Seamless Hybrid Cloud
Extension to cover multiple CSP
Incorporation in OpenStack (an open source Cloud Stack)
