Recently, I guest posted at (IT Trends and Analysis) about WAN optimization best practices, here is excerpt:
WAN Optimization best practices
As enterprise applications gradually moved from being hosted on localized servers at local offices to centralized hosted servers at the headquarter and data centers, it shifted the pressures and challenges on IT from maintaining a large number of distributed servers to making sure that a few servers in the data center keep operations running.. Although centralized hosted servers are less expensive to operate, the business cost of having key servers go down or inaccessible raise considerably. Simply put, if a main server goes down, all branch offices will suffer.
Besides server reliability, the second major factor that affects branch office performance is the WAN link becoming a bottle-neck in the connectivity between the branch and data center. In most cases the uplink speed of a branch office is much lower compared to the WAN connectivity speed of a headquarter office and will throttle down the connectivity speed between those two nodes to the slower of the links, in this case, the branch office WAN link. In some cases, higher bandwidth options for the branch office can be very costly or not available. The problem is more acute for multi-national enterprises as the non-uniformity of the WAN options available can easy become a very messy problem to deal with.
These problems forced the IT industry to develop new ways to optimize the WAN connection through WAN acceleration and Broadband Bonding (a new technique that bonds several Internet access lines into a single high-speed connection)…
