The Oversimplification of SD-WAN for Cross-Cloud Strategy

Are you confident in your cross-cloud strategy? Think again. Many organizations make the mistake of assuming that extending their SD-WAN to the public cloud is as straightforward cross-cloud strategy. This oversimplification can lead to significant operational and scalability challenges. To truly leverage the power of cross-cloud connectivity, you need a well-planned and meticulously designed approach that integrates seamlessly with public cloud networking services. Here’s why your cross-cloud network strategy needs more than just IPsec tunnels between public clouds and why careful planning is crucial for success.


Azure virtual WAN (vWAN): Lessons Learned

Azure virtual WAN (vWAN ) is undoubtedly a strong choice in the wide-area network (WAN) connectivity model, utilizing third-party backbones. It holds significant potential and functionalities, but it is also a relatively immature and evolving service with certain limitations in use cases that deviate from the Azure reference architecture.

In this post, I would like to share my first-hand experiences and lessons learned from integrating vWAN into my use case. I hope that these insights can assist you in making decisions and implementing workarounds to address challenges arising from certain limitations.

Zscaler Internet Access – Client Connector Forwarding Modes

The cloud has fostered the evolution of traditional connectivity models to improve the user and application experience. Security is becoming a growing concern as traditional perimeters are disappearing and a Zero Trust approach is essential in today’s security architectures.

Cisco SD-WAN Policies Introduction

I want to share with you a summary of the key points in SD-WAN Policies, their definition and implementation, to build a flexible and adaptable architecture to the needs of end-users and applications.


SD-WAN – Why is it becoming more and more relevant?

As you know, there has been a huge increase in the use of Software as a Service (SaaS) and Infrastructure as a Service (IaaS) offerings. This has made WAN become the main protagonist to achieve the new technology trends in the industry:


Cisco ACI – Management In-band

This post covers a non-best practice design for the Management Network in Cisco ACI (Application Centric Infrastructure). The implementation of Management In-band instead of the recommended Management Out-Of-Band (OOB). An OOB network increases the odds that you will be able to access the devices in the event that the fabric is experiencing production issues and is unavailable.



The aim of this post is to show a brief comparison of some key points for EVPN/MPLS and VPLS. You can see the details in the table below.
