SD Wan represents the software-defined wide area network, which is used for reducing complications and making it easy for big companies and organizations. Nowadays wide area network is not only about connecting the branch site with the internet. Traditionally, we had a setup in such a way that we use to have two or three transport connections and you may not have the internet reachability directly. Earlier, it was only about WAN. That is why SD Wan edge devices are in high demand.
Connecting multiple sites to the other side and the data center. For example, you have a router and you have a fixed q router at your internet edge that has multiple connections among those. One is going towards the internet, one is going to MPLS. But nowadays, WAN is not about connecting all these devices altogether like a router with a router, etc.It is modified now, and that’s why the SD Wan Edge devices is so much in demand.Talking about its applications, so many applications have moved to the cloud. For example, office365.
Now, you don’t have to download and install office on your local machine if you havethe internet on your cloud anytime you want. Earlier, CISCO launched a technology iWAN and iWAN devices,trying to give some intelligence to their WAN. Now, when they have migrated to SD-Wan devices,this SD Wan is derived from that iWAN technology.
There are some requirements and challenges in WAN. For example, Currently, there are 5-10 websites that you have deployed, but now your network is expanding with a good amount of growth. Let us say you are growing with 50-100 websites every 6 months or a year. So, 50-60 sites of yours are deploying. So, there will be a lot of challenges while expanding your network, like sitting up a router and then the further processes.
Considering all these things like manual overhead. Your manualoverhead should be less. You can do your administrator will be responsible for doing many things manually. For example, the confirmation will be done manually.
- It has network visibility.
- It is of multiple connection types.
- It is of high capacity bandwidth.
Why should you switch yourSD-WAN?
It has a single interface, independence and flexibility, security, rapid provisioning, streamlined management, and smart pathway control. It provides major security with fewer costs and simplifies the management of things.
