I have been updating my ARM templates to create VMs and VM Scale Sets (VMSS) to support the new Availability Zones. I have learnt some important concepts that were not obvious for me along the way, and I would like to share them. Before going forward, you can see a template where you can deploy … Continue reading Migrating your ARM templates to Azure Availability Zones
You have probably heard about Azure Backup (if you haven’t, check the documentation here).

Optionally, you … Continue reading What do Cisco ACI, microsegmentation, service insertion, REST and Docker containers have in common?
Do you have a network lab to try out new technologies? Then you might have experienced this problem: you finished testing technology A, and you start testing technology B. For that you need to reconfigure your devices, obviously. Now you need to try out something new in technology A, for example a new functionality brought … Continue reading Using NX-API to deploy full networks
