WAN acceleration remediates network congestion and latency by implementing bandwidth preservation techniques such as compression, caching , data deduplication, and image optimization. WAN acceleration is not the same as application acceleration because the former is meant to optimize the network, not application performance. Similarly, Web acceleration may have overlapping but slightly different targets or approaches. Nonetheless, WAN acceleration or WAN optimization may be undertaken to help improve application performance as part of an effort intended to achieve application acceleration , which helps organizations provide fast, responsive applications and easy access to data despite increased traffic due to exploding demand for mobile access, remote work, and e-commerce apps.
Many WAN improvements can be accomplished with either physical or logical changes to your network. Businesses are increasingly facing pressures on their WAN setups due to increased use of cloud computing, applications, and other network-wide technologies such as web portals. Numerous different business processes are affected by a slow network. Even simple actions, like employees accessing files, can become unacceptably slow. If the network is dragging, it might take their business-wide file manager a while to load, and then even longer to open the file.
Even though it seems like a small, two-minute task, these problems quickly add up. WAN optimization can potentially allow admins —and their software tools— to more effectively protect all devices and end-users. For many companies, WAN optimization can bring significant improvements to business operations.
Now that you have a little more information on how to maximize your IT infrastructure performance with WAN optimization, I hope you will take my recommendation on incorporating WAN optimization into your enterprise wireless network solution. If you need help figuring out the details or have any questions, feel free to contact us here. At SecurEdge, we are experts in building completely secure wireless networks. We incorporate the latest in next generation security and WAN performance management tools for complete WAN optimization.
We also have some free resources on our site we hope you find them useful. Good luck! For global enterprises, the need for a reliable, private, and lossless network was a key ingredient for this solution to work well across geographies. As a result, WAN optimization was just too cumbersome and expensive for many businesses. Appliances at each location could then point traffic at either MPLS or the public Internet links based on pre-set policies. While offloading less critical traffic to the Internet freed up precious MPLS bandwidth and improved application performance for the mission critical programs riding those trunks, most SD-WAN products still required the enterprise to master and manage a new technology, leaving them with problems similar to the original WAN optimization tools.
As we talk with global enterprises in every geography embarking on digital transformation, we often hear a lot of misperceptions, spin, and blatant falsehoods regarding digital transformation and the use WAN acceleration technology and SD-WAN.
The top myth we hear constantly is that it is still better to go the old fashion infrastructure route when it comes to pursuing SD-WAN, meaning selecting product, deploying assets and shouldering the job of managing the resultant network. It is hard for you to replicate the expertise, scale and rate of innovation of cloud companies such as Amazon et al.
The last thing you want to be doing is acquiring equipment, spreading it to the far reaches of your WAN, and then trying to manage it all, say nothing of keeping it up to date as technology continues to evolve at a breakneck pace. Leave the care and feeding of that network to the experts, companies such as Aryaka that maintain a global private network and deliver SD-WAN as a service.
They start to make compromises as they balance the development needs of the multi-function device, which will make it hard for them to keep up with SD-WAN advances.
And, just as importantly, in the end they are still pushing a hardware-based answer that flies in the face of the new consumption model, as outlined in Myth 1.
With the players in flux and WAN edge strategies continuously evolving, enterprise buyers may be forced to take on some SD-WAN integration work themselves, or, at the least, be prepared to re-evaluate their SD-WAN strategy on an annual basis.
