It can become cumbersome to continue running your playbooks in Cloud Shell.

The VS Code Ansible extension provides better integration experience when you need to work with multiple files so we recommend running Ansible in the remote host via SSH. You can hit `F1` to copy files to remote host.
|

|

1. Hit `F1`; type "Ansible: copy folder to Remote Host"
|

1. Follow the prompt to provide the source directory
|

1. Select "Set up host" if this is the first time. Else select your remote host

Let's modify what you have done so far to create a network of multi-tier applications based on this [Azure CLI sample](https://docs.microsoft.com/en-us/azure/virtual-network/scripts/virtual-network-cli-sample-multi-tier-application).
|
||||
|
||||
Based on the Azure CLI sample, let's build a [network of multi-tier applications](https://docs.microsoft.com/en-us/azure/virtual-network/scripts/virtual-network-cli-sample-multi-tier-application).
|
||||
- a virtual network (172.16.0.0/16) with front-end and back-end subnets
|
||||
- two virtual machines: web and MySQL; one in each subnet
|
||||
|
||||
- a virtual network (172.16.0.0/16) with front-end (172.16.10.0/24) and back-end (176.16.20.0/24) subnets:
|
||||
- Traffic to the front-end subnet is limited to HTTP and SSH
|
||||
- Traffic to the back-end subnet is limited to MySQL, port 3306 and SSH. All outbound traffic from the back-end subnet should be blocked.
|
||||
- two virtual machines, one in each subnet
|
||||
|
||||
|
||||
What you have done so far:
|
||||
- A VNet 172.16.0.0/16
|
||||
- A front-end subnet - 172.16.10.0/24 with NSG rules that allow:
|
||||
- SSH traffic from the Internet to the front-end subnetSSH on port 22
|
||||
- HTTP traffic in from the Internet to the front-end subnet on port 80
|
||||
- And a VM in the front-end subnet that can act as the front-end web server
|
||||
- A front-end subnet - 172.16.10.0/24 with NSG rules that:
|
||||
- allows SSH traffic from the Internet to the front-end subnet on port 22
|
||||
- allows HTTP traffic in from the Internet to the front-end subnet on port 80
|
||||
- And a VM in the front-end subnet that acts as the front-end web server
|
||||
|
||||
You need to add:
|
||||
- A backend subnet 172.16.20/24 with NSG rules that:
|
||||
- allows SSH traffic from the Internet to the front-end subnet on port 22
|
||||
- allows MySQL traffic from the front-end subnet to the back-end subnet on port 3306
|
||||
- blocks all outbound traffic from the back-end subnet to the Internet
|
||||
- A VM in the back-end subnet.
|
||||
|
||||
|
||||
- A VM (MySQL) in the back-end subnet.
|
||||
|
||||
Let's start by restructuring your playbook and break the tasks out into a few playbooks.
|
||||
|
||||
1. Move all common tasks related to subnet configuration to one YAML file say configurenetwork.yml so that you can use the same list of tasks to provision and configure the subnet, public IP etc. networking related tasks.

|

- For the front-end, add a tag by setting `tags: "Ansible=web"`
|
||||
- For the back-end, add a tag by setting `tags: "Ansible=MySQL"`

To create an AKS with monitoring enabled:
