What are the benefits of SD-WAN? You may have heard a lot about this topic. Therefore, I think it is a good time to review the advantages that this technology can bring to an organization.
The Benefits Of SD-WAN, What Are They?
Now that we have clarified these points, we can delve into the benefits of SD-WAN and see how it allows companies to solve the three issues we have mentioned (and some more).
SD-WAN Technology Is Quite Economical
The SD-WAN Network Is Relatively Cheap (especially when compared to private networks such as MPLS). The price difference between one network and another depends on many factors, but it is clear that cost savings are substantial. This is an undeniable fact.
SD-WAN Networks Are Secure
SD-WAN technology is based on the Internet, and this has allowed the costs of the network on which it operates to freeze. However, the level of Internet security has increased because large companies and organizations required certain basic guarantees. In addition, the monthly office 365 [office 365 รายเดือน which is the term in Thai] is an ideal option for office users.
Even so, there is still no standard that defines how to integrate security into SD-WAN networks. There are several formulas, from private networks, based on DMVPN and IPSec, to SaaS security systems offered by third parties (among other options).
Considerable Bandwidth, One Of The Clear Benefits Of SD-WAN
This technology can provide considerable bandwidth simply and economically. This is because the network seamlessly manages the layer linked to bandwidth.
Again, if we compare the price of the bandwidth (in Mbs) of a private network, with that of an SD-WAN network, we will see that the price of the second is much lower. Also, if we consider that the network is based on the Internet, getting more bandwidth does not seem very complicated. What is more complex, although achieved, is to ensure effective bandwidth performance.
Flexibility When Designing The “Underlay.”
SD-WAN service [บริการ sd wan which is the term in Thai] offers flexibility when configuring the underlying network regardless of whether it is ADSL, VDSL, 4G, or LTE. This, in itself, brings various benefits. For example, it allows you to use the most appropriate or economical bandwidth depending on the location of the office or branch. It also allows you to assign different types of lines to different traffics (depending on the level of security or other applicable requirements). The backup system (in case of failure) is guaranteed if the underlay is made up of both fixed and mobile lines.
That said, how the underlying network is created and used is only one of the aspects linked to flexibility. Many of the points that have been mentioned previously also require that the solution be flexible: capacity to cover demand spikes, malleable management and maintenance systems, optional security systems, etc.
