One of the best aspects of working with application-intelligent SDWAN solutions is the ease of configuration for common SaaS solutions such as Office 365. When I compare SDWAN with the traditional router or firewall approach, I begin to see how antiquated products in the WAN space has been, particularly around today’s diverse application deployment models.

I’ve done a pretty deep dive on the ins and outs of SD-WAN over the past few posts. I want to change things up a bit and look at the role that SD-WAN has in your applications. Continue reading
I am always distressed when I go into a small business, such as a doctor’s or dentist’s office and look at the infrastructure supporting them. These companies have my name, address, social security number, medical records, etc. Looking into the back room I see a residential grade router with wireless sitting on the shelf plugged into a simple switch. Shivers down your spine doesn’t fully cover the feeling. Continue reading
This blog post is going a bit outside my usual “make sense to the C-Level” slant. I wanted to get in the weeds about reviewing SD-WAN products. We all know that’s where the fun really is! Continue reading
Multiple flavors of SD-WAN are available on the market today. One area of differentiation amongst them is whether or not there is a vendor-hosted traffic handling component in the architecture. In cases where there is no vendor hosting of traffic handling SD-WAN components, devices owned by the business, or, the existing network, are expected to handle all traffic. In cases where there is a vendor providing hosting of some traffic handling components – such as in a cloud access point of presence (POP) – devices owned by the vendor are responsible for handling some traffic. While on the surface this seems to be an unimportant detail, there are several subtleties that must be considered. Knowing which architecture an SD-WAN solution requires can mean quite a bit when it comes to not only realizing the full benefit of your SD-WAN solution, but also the business implications.

As an ever present staple of technology in the inventory of any major enterprise, WAN optimizers have begun to lose their luster. While there are still probably thousands in widespread use throughout the world, evolution has conspired to put them on the endangered species list. Do you remember thicknet, thinnet, or token ring? Yup! That kind of endangered! Continue reading
If you haven’t noticed, the theme of my last few blog posts centered around cost savings and optimization in the networking field. What better way than that to broach the subject of utilizing broadband as an alternative to private and leased line access.
Traditionally, broadband access has been shunned by businesses of all sizes for critical links, other than for use as a backup VPN link, due to its characteristics. The most commonly identified issues when describing broadband are: Continue reading
The typical branch office consists of a mix of routers, WAN optimizers, switches, firewalls, wireless, and servers. That’s a pretty considerable investment just in hardware to bring up a moderately sized office. When you add in the costs and labor associated with procurement, installation, and configuration it is easy to see how the bill can equal tens, if not hundreds of thousands of dollars per location. Continue reading
If you ask a group of 10 people what SD-WAN ( Software Defined Wide Area Network ) is, there’s a good chance you will get 10 different answers. So, which one is right? Well, that depends on your perspective. If you take all the marketing and jargon out of the equation it will be something like this. Continue reading
