  1. Cloud Computing from a Networking Perspective Per Hansen, Sr. Dir. Enterprise Marketing

  2. Data Center Control Security Performance Scalability Manageability … Virtualization Dynamic Flexible Interface agnostic On-demand Cost allocation Granular … Virtualizing the Data CenterA First Step Towards an Internal Cloud Source: VMware

  3. App Loads App Loads App Loads Federation The Private Cloud • Leveraging the cloud concept •  Control •  Security •  Performance •  Scalability •  Manageability •  Dynamic •  Flexible •  Interface agnostic •  On-demand •  Cost allocation • Granular • … DC B DC A Ext. Cloud DC C

  4. New Emerging Network Architecture Addressing specific connectivity needs • User/office access to the private cloud • Internal cloud communication (data center to data center) • Internal to external cloud communication (data center to ext. cloud) Int. Cloud Ext. Cloud Office Cloud access/ interface User

  5. Cloud Inter-DC Applications Special-application clouds • Trading/transaction execution Multi-application clouds • Virtual machine migration • Load balancing, up/down ramping • Follow sun, follow moon operations • Disaster avoidance, disaster recovery • Cloud “bursting” • Remote access to consolidated data centers • Pre-positioned data placement to cloud • High-performance “fat pipes” on demand • 8 – 32 – 320 GB in minutes • 1-10-100 Gb/s • msec deterministic latencies • True Zero packet loss • Layer 2 addressing • Model specific requirements • Connect to original VM data center where storage may remain • Temporary connection over short period for storage migration … and/or post-burst database consolidation • Rerouting of user connections rooted at original data center • …

  6. NYSE Ultra Low Latency Network First 100Gbps Network “Powering our new data centers and network with Ciena technology will help produce a clear competitive advantage for NYSE Euronext and our customers in terms of executing trades and delivering mission critical information as well as advancing leading edge applications such as state-of-the-art co-location facilities.” Stanley Young, CEO of NYSE Technologies and Co-Global CIO of NYSE Euronext

  7. Data Center Multi-Application CloudsNetwork Architecture Current implementations are network centric, static and disjointed But… • Virtual Machine concept: server and storagevirtualization across hardware boundaries • Server virtualization needs a more dynamic and flexible network • New applications for dynamically moving workload to another data center (e.g. VMotion, Site Recovery Manager) require more deterministic, scalable, on-demand performance and management – i.e a flatter Layer 1/2 network Headquarter SONET/SDH e.g. 3000km Ext. cloud OTN / WDM e.g. 200km Carrier Ethernet; IP/MPLS e.g. 750km Data Center Int. cloud Branch Office

  8. Data Center Evolving the Network Architecture One logical network resource • Any bandwidth, topology, protocol/application, distance • Simple, unified presentation & management • Improved resource allocation and operational efficiencyDynamic Bandwidth Allocation, Compression, …Service CoS on demand, … • Converged network efficiencies Headquarter SONET/SDH e.g. 3000km OTN / WDM e.g. 200km Carrier Ethernet; IP/MPLS e.g. 750km Private cloud Data Center Branch Office
