Overcome network performance challenges with WAN Optimization
By Paul Rummery, Securenet Consulting
Solving Bandwidth / Application Latency from Cloud Infrastructures
Bandwidth capacity or lack of it, can impact the end users Cloud Computing / Application experience. Private lines are more expensive than public lines, and as companies expand, IT administrators are challenged to resolve high latency and excess bandwidth usage.
Mission critical applications require higher priority because they require adequate bandwidth.
Maybe you already employ an MPLS or other private line service, to access your cloud data centres, but there is still the risk of an outage by that provider / link. Smaller offices may only use Internet-based connectivity to access these data centres, and will need the ability to failover in the event the primary internet line fails.
In both scenarios, it is a popular consideration to acquire some inexpensive Internet broadband based lines, to ensure uptime for office requiring access to cloud services.
In both scenarios, it is a popular consideration to acquire some inexpensive Internet broadband based lines, to ensure uptime for office requiring access to cloud services.
One solution would be to ‘aggregate’ two or more lines from public internet service providers, using a WAN optimisation appliance. These appliances also provide high availability and auto line failover in the even one of the ISP’s line / networks fail.
By aggregating multiple lines together, you are able to serve more data, maintain speeds, thus fix QoS (quality of service) for business critical applications, ensuring an always good end user experience.
WAN Optimisation Solutions Deliver
