Boost PowerShell with Resource Graph queries in Azure

Par : Baki Onur Okutucu

Can you imagine how long it would take to generate a list of VMs across hundreds of subscriptions on Azure? It would take ages not only to create a list of resources but also to find a single resource in a massive environment. As we know, Azure Portal only lists the first 1000 subscriptions, and it is not really convenient to query resources using the portal when you have a lot of subscriptions. Fortunately, we've got the option to query resources in a much faster and more dynamic way. In this post, we will cover Azure Resource Graph and use it with PowerShell for even more flexible query management.

VMware vSAN Automatic Rebalance vs. Proactive Rebalance

Par : Vladan Seget

VMware vSAN's Automatic Rebalance capacity is part of vSphere 7 U2. What is the difference between vSAN Automatic Rebalance and vSAN Proactive Rebalance? Storage usage higher than 80% triggers reactive rebalancing. A difference of 30% between vSAN capacity disks will trigger vSAN's Proactive Rebalancing function.

Disable NetBIOS in Windows networks

Par : Brandon Lee

NetBIOS was initially created to allow applications to communicate without understanding the details of the network, including error recovery. It operates at the session layer, layer 5 of the OSI model. As with other legacy technologies, the main reason for disabling NetBIOS is security. There are two ways to achieve this goal: via either DHCP or a registry key.

Migrating roles and features to Windows Server 2022 using WSMT

Par : Brandon Lee

The Windows Server Migration Tools (WSMT) have shipped with Windows Server since version 2003. Admins can use them to transfer roles and features to a newer version of the operating system. Since Microsoft hasn't updated these tools for quite some time, they show some bugs when used with Server 2022. Nevertheless, the WSMT are still a viable option when upgrading Windows Server.

Delete the Amazon Machine Image (AMI) and its associated snapshots

Par : Mohamed Wali

Whenever you create an Amazon Machine Image (AMI) out of an EC2 instance with multiple EBS volumes, it takes a snapshot of every volume attached to this EC2 instance, if specified. So when you decide to delete this image, it won't automatically remove the corresponding snapshots. In this guide, you will learn how to remove all AMI snapshots on the AWS Console with the AWS CLI plus bash and with PowerShell.

Install Windows 11 in a virtual machine

Par : Wolfgang Sommergut

The new hardware requirements for Windows 11 apply not only to physical devices but to virtual machines as well. The advantage of virtual machines here is that PCs without a physical TPM can install a virtual one instead. Other requirements, such as Secure Boot, can also be met in a VM
