When you work with JSON on powershell to chnage/replace arrays/list . you will see Convertto-Json will change your Azure compliant ARM template and put @ in front of arrays. This may cause issues in deployment.

Filter : {@{resource=; resourcegroup=}}

$TargetFile | ConvertTo-Json -Depth 50 | % { [System.Text.RegularExpressions.Regex]::Unescape($_) }

Output : 

“resource”: {
“property”: “name”,
“condition”: “like”,
“resourcetype”: “*”
},
“resourcegroup”: {
“property”: “resourcegroupname”,
“condition”: “like”,
“subscription”: “sub-xyz”
}

When Azure planned reboots occurred we have seen performance degradation on several VMs . Here is the quick fix which doesn’t cost anything extra.

We need to enable Accelerated networking to overcome this problem . process is pretty simple

Note : This solution only works on VM that is not a member of availability set.

Steps to enable accelerated networking

1. Deallocate VM
2. Note NIC Name and resource group name where nic reside
3. Assign new NIC to VM
4. Deallocated old nic .
5. Run below on cloudshell

az network nic update --name NICNAME --accelerated-networking true --resource-group RESOURCEGROUP

 

6. Assign old nic back to the VM
7. Deallocated new NIC and start VM

# Use the following command to list all the Authorisations currently associated with the ExpressRoute circuit 
# If required use the Remove Authorization commend to tidy up any authorisations with unused links 

Get-AzureDedicatedCircuitLinkAuthorization -ServiceKey *** # This should show all the existing authorisations
