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

  Multiple Tenants sharing E2E

  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)

  Standardization   Tenant CSP, CSP CSP interoperability, interfaces   Compute/VM, Storage and Network level interoperability,

interfaces
