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
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. Multi-Application Clouds Network Architecture
Current implementations are network centric, static and disjointed
But…
Virtual Machine concept: server and storage virtualization 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
