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 …

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

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 Headquarter SONET/SDH e.g. 3000km Ext. cloud Data Center OTN / WDM e.g. 200km Carrier Ethernet; IP/MPLS e.g. 750km Data Center Int. cloud Branch Office
