In this final part of the series, let us briefly look at what the end customer of a Cloud computing service will gain if the service provider uses some or all of the above mentioned techniques (in Part I, II, and III) of WAN optimization in architecting the solution:

WAN optimization boosts user productivity. Point-products and isolated optimization solutions can be discarded in favor of a single unified application that makes WAN optimization the cornerstone for application delivery. This reduces time to market and accelerates user data access and management capabilities.

WAN optimization can be easily integrated into a multi-platform, multi-application environment to deliver quality of service, network performance visibility, and application-aware control.

WAN optimization manages bandwidth by using de-duplication, compression.  The amount of bandwidth required can be reduced and a defensible return on investment (ROI) can be determined.

Performance problems that arise from remote data access can be overcome by use of caching and other related techniques. When this is applied in conjunction with data center consolidation, it reduces costs, increases control, and delivers efficiency. Latency issues are no longer an overwhelming problem. Data can be delivered at a LAN speed to even remote branches of an organization.

WAN optimization straddles the network, applications and storage and consequently the benefits of optimization seem ubiquitous.  It is, therefore, not surprising that the techniques have been incorporated into the very design of the Cloud backup and recovery software and is used to shape the performance lifecycle of IT in the organization. They provide a deep visibility into the application/network performance and can be used to understand “where” and “why” exactly the shoe pinches and what the impact on the organization using the network is.

WAN optimization efforts deliver “branch office” and ‘mobility” solutions. Cloud backup software, that is optimized for WAN, can make for flexible deployment and virtualization sans latency problems. WAN optimized print servers, file servers, Active Directory, streaming media, firewalls, routers and other custom applications can be deployed in branch offices cutting energy costs and promoting green initiatives. Mobility solutions can be integrated for connecting mobile workers efficiently to the enterprise network. Data center consolidation with WAN optimization will drive IT efficiency / cost effectiveness for Disaster Recovery.

Radical Cloud backup vendors are exploiting WAN optimization techniques to make Cloud integration easier and cheaper.
