Banking on WAN optimisation

Nurdianah Md Nur | Sept. 26, 2014
WAN optimisation will enable financial institutions to improve employee collaboration while ensuring that sensitive data remains secure, said Tricia Png of Silver Peak.

Virtualisation is the other area of consideration. Financial institutions should evaluate only  WAN  optimisation  providers  with  software-based  offerings,  even  if  the  financial institution  is currently interested in hardware. Virtualisation has proven to reduce operating costs and improve IT flexibility. Moreover, while the historical perception  is that only hardware WAN optimisation can   provide the   highest   levels  of  data  transfer,  current advancements  in WAN  optimisation  have proven that virtual WAN  optimisers can perform just as good or better than their hardware equivalents.

Financial institutions  that  have  embraced  big data  and  cloud  are poised  to take  full advantage  of software-based WAN optimisation, as they would already have the necessary infrastructure and architecture in place.

Is WAN optimisation able to work with software-defined  networks (SDN) and network virtualisation?
Definitely. Silver Peak's WAN optimisation services are software-based and can be deployed on any hypervisor. Silver Peak's Unity software -defined WAN (SDWAN) fabric creates an overlay that unifies the existing enterprise WAN with the Internet and cloud services. Unlike traditional WAN optimisation solutions, Unity correlates information about cloud services and Internet "weather" to intelligently route traffic over a secure, optimal path. And by keeping SaaS and IaaS traffic on the Unity fabric, IT gains an ability it never had: the ability to monitor and control connectivity to the cloud  while ensuring consistent performance  for all enterprise  applications, including SaaS.
