Why WAN and Application Accelerators Aren’t Enough:

How IT 1.0 Drives Up Your Bandwidth Costs

WAN and Application Accelerators are great for general purpose acceleration and are fine for streaming and other applications where 100% of a large file must be transmitted. But they simply weren’t designed to accelerate multiple types of file or Binary Large Object (BLOB) data like email, applications and database files. So, if you’re doing collaboration in the cloud, or if you have a sluggish application operating under severe bandwidth constraints, these accelerators can never deliver order-of-magnitude improvements. Instead, they will give you only marginal benefits and barely make a dent in your data transmission costs.

Here’s the problem in a nutshell. First, if only 10% of your file or BLOB has been changed and bandwidth, fidelity and/or latency are problems, why should you replace 100% of it? Second, shouldn’t you be using the best compression technologies available to make even that 10% of your file/BLOB as small as possible? Whether you do collaboration in the cloud, store massive BLOBs, operate a data center or are a mobile/document collaboration provider, the fact is that replacing all the data when you’ve changed only a portion of it is wasteful, inefficient and ineffective­—no better or more logical than using a blowtorch to kill an ant.

How did this problem come about? Because Information Transfer is done today the same way it was done decades ago—we call that Information Transfer 1.0 or IT 1.0. Sure, data gets moved faster than previously, but that’s because everybody added bandwidth, put in bigger pipes and focused entirely on creating more room and more speed. The problem is that this massive provisioning solution has major limitations—it’s equivalent to putting a super-expensive, super-powerful rocket engine on the family sedan. The truth is you don’t need to provision at all when you can send all the changed data in one small replacement file.
