When it comes to connectivity, scalability, and security, organizations often face an important decision: opt for a traditional network architecture or for Microsoft Azure's Virtual WAN. But which one is the best fit for your company? We are happy to help you make the right choice. Let's take a look together at the advantages and potential issues of the Virtual WAN model.

Virtual WAN is an Azure network service, managed by Microsoft, that offers you optimal and automated connectivity on a global scale. However, when this hub-and-spoke architecture first hit the market in 2019, it was still missing many important network features. And it had quite a few limitations, which meant it couldn't meet the needs of the general public: "to provide a unified framework for networking, cybersecurity, and routing".
But in the past 5 years, Microsoft has worked very hard to improve this service. They have added
Before we delve into the pros and cons, it might be useful to first examine the various services and components of Azure Virtual WAN. And to discover how they provide high-speed connections with the Azure backbone:
When you combine these services and features, you can expand your network architecture. You ensure secure transit connectivity paths between multiple spokes, branches, and regions.
Complete mesh hubs through which all traffic flows. Upon creation, you get an address space and various routing tables.
These connections ensure interregional connectivity between all on-prem and Azure network endpoints.
This component supports custom routing tables for virtual networks. And functions as a default table for branches (P2S, S2S, ER). Additionally, it also connects to routing tables. And distributes routes from connections to tables.
There are different types of connections:
This provides additional security, thanks to the integration of the Azure Firewall Manager. With it, you can:
There are 2 variants of Azure Virtual WAN: basic and standard. At Arxus, we only implement the standard version because the basic variant only supports S2S VPN connections.
An Azure Virtual WAN architecture has quite a few advantages:
Although Azure Virtual WAN offers many advantages, there are also some potential disadvantages to consider:
At Arxus, we're eager to help you maximize your cloud solutions. In our opinion, Azure Virtual WAN offers more advantages than a traditional hub-and-spoke architecture. We're happy to think along with you!
Managing your IT environment? That takes quite a bit of work. Especially if you're running virtual machines both in the cloud and on-premises, like the National Lottery. Luckily, Azure Arc offers a much simpler solution. With it, businesses can now easily manage all of their virtual machines in their entire infrastructure. Wondering how that works? We're more than happy to tell you all about it!
The digital landscape is changing faster than ever before. Creating a resilient and reliable cloud infrastructure is therefore essential to stay ahead of your competitors. But how do you start? With the Azure Resiliency Strategy, based on the Well-Architected framework, you lay a solid foundation for high availability and disaster recovery. Curious about how it works exactly? Let's dive right in.
