Instructions?

Here - don’t be dismayed.

The Graphical Way? Peering virtual networks, so virtual machines can talk to each other. The Powershell way? A bit more involved.

Today's Schedule:

• Configure a network security group + security rules using Powershell.
• The application server should connect to the database server over HTTP.
• BUT the database server shouldn't use HTTP to connect to the application server.

The Bullet Points

• Peered Virtual computers in a network in Azure for connectivity using Bash.
• Created new virtual network for machines to live in with Private Endpoint Network Policies enabled
• Enabled SSH connectivity with bash code through CMD line.

The first hurdle was getting the command to work.

`*tion>rg=Paolin At line:1 char:39

• az group create --name $rg --location rg=Paolin+                                       ~The '<' operator is reserved for future use.+ CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException+ FullyQualifiedErrorId : RedirectionNotSupported*`

Until I tried it in bash:

*rg = 32 az group create --name $rg --location eastus*

Some numbers are changed below.

{   "id": "/subscriptions/a78003f1-5023-7uf2-ae36-d07e6nm6d72f/resourceGroups/32",   "location": "eastus",   "managedBy": null,   "name": "32",   "properties": {     "provisioningState": "Succeeded"   },   "tags": null,   "type": "Microsoft.Resources/resourceGroups" }

I made a new subnet, named it (Apps), addressed it, and tied it to a group:

`*m@Azure:~$ az network vnet create \

--resource-group $rg \ --name ERP-Servers \ --address-prefix 10.0.0.0/16 \ --subnet-name Apps \ --subnet-prefix 10.0.0.0/24*`

There's a lot of return information:

• DDoS protection is not enabled (This resource will have been shut off by the time this posts)
• Provisioning state has succeeded.
• No BGP communities
• Private Endpoint Network Policies are Enabled

I repeat it for the Databases subnet:

az network vnet subnet create \\     --resource-group $rg \\     --vnet-name ERP-servers \\     --address-prefix 10.0.1.0/24 \\     --name Databases

The commands

look similar, but they are not - one has

subnet create

the other only

create

They are both in Resource Group 32, but have different address prefix allotments.

Finally; The Network Security Group.

az network nsg create \     --resource-group $rg \     --name ERP-SERVERS-NSG
