1 Ralph Santitoro Director of CE Market Development Meeting the Challenges for Cloud Service Delivery over Carrier Ethernet Networks

2 November 8, 2011 NIST Cloud Computing Definitions with EaaS (Ethernet as a Service) augmentation Tablet Applications SaaS [application] PaaS [platform] IaaS [IT infrastructure] EaaS [WAN infrastructure] Internet Internet WAN Network 2 Building Virtualized On Demand Cloud Networks Ethernet WAN Network

3 November 8, 2011 Network Service Provider Requirements to Support On-Demand Cloud Applications Elastic Ethernet Service Attributes On-demand ability to request EVC or Ethernet service attributes be added or modified for a specific time period Once time period ends, they revert back to their prior state Example Elastic Attributes Increase CIR of existing EVC Add an EVC with associated service attributes (e.g., CIR, CoS, etc.) Modify CoS performance objectives of existing EVC (e.g., Frame Loss) On-demand billing approaches Usage-based billing ($ per MB) based on networks/providers traversed (metro/region/national/international) Fixed rate based on duration of service usage ($ per hour/day) Network/Cloud/Subscriber Management Orchestration 3 Building Virtualized On Demand Cloud Networks

4 November 8, 2011 Management Orchestration Workflow 4 Building Virtualized On Demand Cloud Networks Customer Portal Cloud Provider Management System Ethernet Cloud Carrier Management System Add VMs and Storage Add BW, CoS, EVC, etc. Cloud Service Orchestration Service Attribute Correlation Cloud Provider Cloud Consumer Ethernet Cloud Carrier Orchestration among the different management systems results in consistent Quality of Experience for the Cloud Consumer

5 November 8, 2011 Cloud-WAN Service Correlation Challenges How to correlate between different provider resources for a given Cloud application Cloud Provider VMs and Storage Ethernet Cloud Carrier Network Resources (BW, Availability, Capacity) Simple Example: MRI Image Processing Cloud Service 500 VMs required to process MRI in 2 hours, 1000 VMs for 1 hour Network BW selected based on upload time for a given MRI file 50Mbps to upload file in 20 minutes, 200Mbps to upload file in 5 minutes More Complex Example: Cloud Consumer wants 200 employees to use a cloud application for 1 week 10 VMs required to support 200 users What network BW or QoS is required for the given cloud application? 5 Building Virtualized On Demand Cloud Networks More standards development work needed in this area

6 November 8, 2011 Cloud Service delivery Challenges for Large Enterprises Today, Internet is predominant method to connect to cloud services Cloud Community has given little attention to WANs Larger Enterprises hesitant to move mission-critical applications to the cloud when delivered via the Internet Concerns with Security, Performance, Data Governance/Regulatory Compliance 6 Building Virtualized On Demand Cloud Networks Cloud Provider(s) Internet Enterprise Cloud Consumers The WAN is critical for cloud service performance Insecure Unpredictable availability Inconsistent performance Uncontrolled by IT Dept.

7 November 8, 2011 Cloud Service Delivery via Packet Optical Networking with on-net Private Cloud Services Addresses Internet concerns of large enterprises Security, privacy, availability, data governance and compliance Positions Ethernet SP as the turnkey provider Private cloud services and Ethernet services with SLAs 7 Building Virtualized On Demand Cloud Networks Enterprise Cloud Consumers Ethernet Service Provider On-net Private Cloud Services Internet Public Cloud Services Secure Predictable Availability Deterministic Performance Controlled by IT Dept.

8 November 8, 2011 WAN Service Provider 8 Building Virtualized On Demand Cloud Networks The WAN Service Provider Solution Gap View network as commodity Shop around for lowest price per Megabit View cloud provider higher in value chain Multiple agreements for cloud and network Cloud Service Provider Enterprise Cloud Consumers Higher customer loyalty once relationship is established Leverage Internet to connect to Cloud Consumers Secure / Robust WAN But driven to commodity WANs being driven to commodity pricing Limited unique customer experience / value Need a strategy to move up the value chain Investment in cloud expertise/facilities is substantial WAN Service Provider acts as a Cloud Services Broker

9 November 8, 2011 Requirements for Private Cloud Service Delivery over Metro Ethernet Networks Ethernet Services/WANs must support the following as new Cloud Services/Applications (XaaS) are instantiated/terminated Dynamically add and remove WAN bandwidth Align Ethernet service bandwidth and quality of service (QoS) with the XaaS VM compute and storage requirements High reliability connections to ensure always available XaaS Deterministic QoS performance (packet latency / loss) to ensure consistent end-user quality of experience (QoE) Well-defined demarcation between Metro Ethernet and Cloud Providers networks to facilitate service troubleshooting Ethernet Service/WAN security must align with Cloud Providers security in order to meet security compliance and regulatory requirements 9 Building Virtualized On Demand Cloud Networks Packet Optical Networking well suited to meet these requirements
