A north-south traffic flow is user-to-machine through a tiered IP network architecture. This reflects a client/server model and is exercised in the cloud for SaaS-type applications where the application is simply moved from the in-house data center to the cloud provider data center server. East-west traffic flows are machine-to-machine within, and increasingly between, data centers. Such traffic has much more stringent quality-of-service requirements. In the near-future, we’ll see at least an order of magnitude more east-west data workloads driven by applications like storage synchronization, inter-data center storage virtualization and virtual machine migrations. This means the cloud network needs to be designed for performance to meet the traffic flow change and intensity challenges of the future.

While much of the industry is focused on what’s going on in enterprise networking inside the data center to enable cloud computing, IT also needs to consider the network that connects the data centers – particularly how these inter-data-center networks need to change to support new cloud use cases and associated network requirements for bandwidth scalability, low latency, security, virtualization and automation. In this slideshow, Ciena is tackling the connectivity issues between data centers, and data centers to the cloud, and outlines 10 reasons why you need a better network to the cloud.
