WAN Optimization Accelerates App Delivery Across Hybrid WANs
WAN optimization is becoming an attractive option for companies that are growing globally and need to support an increasing number of large branch offices and remote locations. By some estimates, large enterprises have up to 80% of their workforce in regional locations, according to Nemertes Research. All those workers want to be productive wherever they are. That means they need efficient access to important corporate data and enterprise applications under whatever circumstances they’re working. In today’s distributed enterprise – where data volumes are growing and rich apps generate lots of network traffic and congestion – WAN optimization has become practically de rigueur to ensure more effective use of the networks that unite organizations. WAN optimization improves response times for users of business-critical applications over WAN links or mobile connections, helping tackle application performance problems caused by bandwidth constraints, latency or protocol limitations. The technology continues to have as its main use optimizing the connection between remote users and centralized IT resources. Optimizing data replication between data centers is another key function. Optimizing traffic to mobile devices and accessing externally hosted applications, like those in the cloud is also an important use case for the technology. WAN optimization adoption is growing as cloud computing and SaaS apps gain a greater foothold in the enterprise, and as more companies look to the hybrid WAN model that lets them leverage combinations of MPLS, VPLS, VPWS, VPN and Internet and cloud connectivity services.
