Contents
• Cloud Service Delivery Challenges for Large Enterprises
• Carrier Ethernet Benefits for each Cloud Stakeholder
• New MEF cloud definitions and terminology
• Use Cases – MEF Ethernet services for delivering cloud services
• New MEF work – Augmenting Ethernet services better align with on-demand
Cloud Service requirements

Enterprise Cloud Service delivery Challenges
• Today, Internet is predominant WAN to deliver cloud services– Surprising, little attention paid to it by the Cloud Community
• Larger Enterprises hesitant to move mission-critical applications to the cloud when delivered via the Internet
The WAN is critical for cloud service performance (SLAs)
Cloud Service Delivery Challenges over the Internet
• Security Vulnerabilities• Performance• Data Governance• Regulatory Compliance

Cloud Service Delivery via Carrier Ethernet WANs
• Addresses Internet challenges for mission critical apps.– Using Carrier Ethernet to connect to private cloud providers
• Generates additional telecoms provider revenue– Private cloud services and Ethernet services with SLAs

CE Benefits for each Stakeholder
• Enterprise Cloud Consumer – Puts Enterprise IT department in control– Meets Enterprise requirements for high performance, secure
and controlled access to mission critical cloud applications
• Cloud Providers– Enables new Private Cloud business opportunities– Ability to better differentiate cloud service offerings
• Ethernet Cloud Carriers– Enables telecoms providers to deliver mission-critical Cloud-
based services– Telecoms providers can leverage well-established, trusted
relationship with their enterprise subscribers

Ethernet Cloud Carrier
The intermediary that provides Carrier Ethernet connectivity and transport of cloud services from Cloud Service Providers and Cloud Consumers and with other Ethernet Cloud Carriers.
Cloud Broker
An entity that manages the use, performance and delivery of cloud services, and negotiates relationships between Cloud Service Providers, Cloud Consumers and Ethernet Cloud Carriers

Business Relationships in the Cloud Model
Augmentation of U.S. National Institute of Standards and Technology (NIST) Cloud Broker Definition

Cloud Broker Definition Clarification
• NIST Cloud Broker Definition is very generic– Appears to assume only Internet WAN connectivity
• MEF augments NIST definition and provides more use cases– Ethernet Cloud Carrier acting as a Cloud Broker– Cloud Service Provider acting as a Cloud Broker– Cloud Broker (pure reseller model)
1515
Ethernet Cloud Carrier acting as a Cloud Broker
• Business relationship: Ethernet Cloud Carrier to Cloud Consumer– Ethernet Cloud Carrier wholesales cloud services from Cloud Service
Providers• This Cloud Broker analogous to telecom service provider
delivering Internet access services– Telecom SP provides network connectivity to customer premises– Telecom SP provides Internet access service like an ISP

Cloud Service Provider acting as a Cloud Broker
• Business relationship: Cloud Service Provider to Cloud Consumer– Cloud Service Provider wholesales network connectivity from
Ethernet Cloud Carrier
• This Cloud Broker is analogous to an ISP– ISP wholesales access network connection from incumbent telecoms
service provider who owns access lines to the customer premises– ISP provides network connectivity to customer premises and Internet
access service

Cloud Broker (pure reseller model)
• Business Relationship: Cloud Broker to Cloud Consumer– Cloud Broker wholesales network connectivity from Ethernet Cloud
Carrier(s) and cloud services from Cloud Service Provider(s)
• This Cloud Broker is analogous to a mobile virtual network operator (MVNO) – MVNO sells cellular voice/data services but does not own/operate
a cellular wireless network

Ethernet Service Attributes being Evaluated to Better Support Cloud Applications
• Elastic Ethernet Service Attributes– On-demand change of EVC or UNI attributes for specific time period
• Once time period ends, revert back to prior state• Investigating on-demand and reservation models
• Example Elastic Attributes– Increase CIR of existing EVC– Add or Remove UNI endpoints in
multipoint EVP-LAN or EVP-Tree service
• On-demand bandwidth approaches– Based on bandwidth usage (X MBytes/month)– Based on CIR and/or EIR (200 Mbps CIR and 400 Mbps EIR)
• Network/Cloud/Subscriber Management Orchestration– End-to-End service management and SLAs
