WAN optimization tools are used mainly in application delivery networks which consist of WAN Optimization Controllers (WOCs) and Application Delivery Controllers (ADCs). On the data center end Application Delivery Controllers are present to distribute the traffic among servers based on application specific criteria. In the branch office portion of Application Delivery Controllers, WDC are present that uses its advanced compression and flow optimization capabilities to provide application availability, security, visibility, and acceleration. WAN Optimization mitigates the latency and bandwidth limitations of the WAN to provide remote users with access to applications in the data center.
IT departments have been trying to take initiatives to meet their business objectives to reduce costs and consolidate resources. WAN optimization …show more content…
Many organizations have consolidated to centralized data centers which often has a backup data center from regional data centers. These typically large data centers are deploying state-of-the-art servers that use virtualization in increase IT nimbleness. As a result, users who were close to a regional data center now find themselves distant and the users often experience poor application performance due to latency and congestion over the network.
Branch-Office Server Consolidation
Branch office consolidation is centralizing the domain, print and application servers to a single server running virtualized software and then transmitting this data to a corporate data. This reduces server and server administration costs due to few and larger, virtualized servers, compliance risk through centralized storage of data, and simplified backup and disaster recovery. This technique, however, increases traffic across WAN. Application performance over the WAN is degraded because of this.
