2012 Cloud Prediction – Enterprises Will Realize They Need a Better Network to the Cloud

Contributed Article by Jim Morin, Product Line Director, Managed Services & Enterprise, Ciena Corporation

If 2011 was the year that enterprises started truly adopting the cloud, then 2012 will be the year they start realizing the need for more intelligent networking connectivity to cloud-based resources, and work to implement such a model. 

Several factors are driving requirements for more robust enterprise-to-cloud networks, including the need to accommodate the rapidly increasing data transfer workloads between enterprise data centers and cloud data centers. For example:

  • VM transfers between data centers are quickly moving from today's trickle to a torrent, along with the advent of server instances that have much larger memory and more associated storage. For example, vApps with a number of associated VMs will be in motion, and a single VM memory size can now reach 1 TByte. 
  • Virtual storage is no longer isolated to the data center - it is now shared between enterprise and cloud data centers in active/active configurations, driving increased levels of storage synchronization data flows.   
  • An increasing number of mission critical enterprise applications being deployed as VMs are moving to the cloud, driving the need for carrier-class network security and performance for workload balancing.
  • Greater adoption of cloud-based infrastructure (IaaS) for workload mobility, collaboration and availability extends networking requirements over greater geographic distances between data centers and results in more complicated topology deployments. 

With a more flexible and intelligent network to the cloud, enterprises will finally be able to realize the promise of a "data center without walls,"or in other words, a completely virtual data center. This industry model will consist of an active/active architecture that replaces passive backup architectures to enable greater mobility, collaboration and availability, as well as the operation of both private and cloud infrastructures and services independent of physical location. Specifically, this new technical architecture will feature a server, storage and intelligent networking infrastructure.

There are many benefits of the "data center without walls" model, including scalable capacity, built-in security and the flexibility to access resources on-demand via a pay-per-use model. Overall, the approach will enable IT to manage workload peaks and valleys while incurring only incremental operational
expenses, rather than having to make expensive capital investments in underutilized capacity. A dynamic, intelligent network between enterprise and cloud resources will also enable the deployment of applications in any location, allowing organizations to lower costs by using their resources more efficiently
and also to ensure the best performance. Additionally, a flexible all-points network will give IT organizations more options for developing and deploying applications without lock-in to a physical data center location or provider. 

As a whole, the "data center without walls" model will provide IT organizations with a completely automated virtual data center operation, independent of location, while also minimizing capital expenditures and increasing agility.
