VNet-to-VNet VPN connections in Azure allow you to securely connect two or more virtual networks (VNets) across Azure regions. This is useful for scenarios like cross-region failover, data replication, or connecting workloads in different locations. For example, two sites in East Asia and East US may need to share data, replicate databases, or back up services. A VNet-to-VNet VPN in Azure provides a secure, encrypted link between them, allowing resources to communicate as if they were on the same local network.. In this guide, we will configure a VNet-to-VNet VPN connection between two VNets based on the configuration from our…

Ansible AWX is a great tool for automating tasks like patching Linux servers at night. It’s easier to use than regular Ansible Galaxy because AWX integrates well with Active Directory (AD) through LDAP. I also like that AWX can schedule tasks to run automatically and send notifications to Slack when the task is done. AWX makes it simple to store playbooks in Git, and it can even automate tasks with network devices like F5 load balancers. Here’s a playbook I use to update Ubuntu servers: — hosts: linux serial: 1pre_tasks: – name: Disable PRTG service: tasks: – name: Update apt…

Robocopy is a powerful Windows command-line tool designed for copying large files and directories while preserving directory structure, access permissions, and other attributes.
