Mission LZ

Mission Landing Zone is a highly opinionated Infrastructure-as-Code (IaC) template which IT oversight organizations can use to create a cloud management system to deploy Azure environments for their workloads and teams.

Mission Landing Zone addresses a narrowly scoped, specific need for a Secure Cloud Computing Architecture (SCCA) compliant hub and spoke infrastructure.

Designed for US Government mission customers
Implements SCCA controls following Microsoft's SACA implementation guidance
Deployable in Azure commercial, Azure Government, Azure Government Secret, and Azure Government Top Secret clouds
A simple solution with low configuration and narrow scope
Written as Bicep and Terraform templates

Mission Landing Zone is the right solution when:

A simple, secure, and scalable hub and spoke infrastructure is needed.
A central IT team is administering cloud resources on behalf of other teams and workloads.
There is a need to implement SCCA.
Hosting any workload requiring a secure environment, for example: data warehousing, AI/ML, and containerized applications.

Design goals include:

A simple, minimal set of code that is easy to configure
Good defaults that allow experimentation and testing in a single subscription
Deployment via command line or with a user interface
100% Azure PaaS products

Our intent is to enable IT Admins to use this software to:

Test and evaluate the landing zone using a single Azure subscription
Develop a known good configuration that can be used for production with multiple Azure subscriptions
Customize the deployment configuration to suit specific needs
Deploy multiple customer workloads in production

What is a Landing Zone?

A landing zone is networking infrastructure configured to provide a secure environment for hosting workloads.

Quickstart

You can deploy Mission Landing Zone from the Azure Portal or by executing an Azure CLI command.

You must have Owner RBAC permissions to the subscription(s) you deploy Mission Landing Zone into.

Deploy from the Azure Portal

Deploy Mission Landing Zone into AzureCloud or AzureUsGovernment from the Azure Portal:

Azure Commercial Azure Government

After a successful deployment, see our examples directory for how to extend the capabilities of Mission Landing Zone.

Deploy using the Azure CLI

Clone the repository and change directory to the root of the repository:
```
git clone https://github.com/Azure/missionlz.git
cd missionlz
```
Deploy Mission Landing Zone with the az deployment sub create command. For a quickstart, we suggest a test deployment into the current AZ CLI subscription setting these parameters:
- --name: (optional) The deployment name, which is visible in the Azure Portal under Subscription/Deployments.
- --location: (required) The Azure region to store the deployment metadata.
- --template-file: (required) The file path to the mlz.bicep template.
- --parameters resourcePrefix=<value>: (required) The resourcePrefix Bicep parameter is used to generate names for your resources. It is the only required parameter in the Bicep file. You can set it to any alphanumeric value (without whitespace) that is between 3-10 characters. You can omit this parameter and the az deployment sub create command will prompt you to enter a value.
Here's an example:
```
az deployment sub create \
--name myMlzDeployment \
--location eastus \
--template-file ./src/bicep/mlz.bicep \
--parameters resourcePrefix="myMlz"
```
After a successful deployment, see our examples directory for how to extend the capabilities of Mission Landing Zone.

Don't have Azure CLI? Here's how to get started with Azure Cloud Shell in your browser: https://docs.microsoft.com/en-us/azure/cloud-shell/overview

For more detailed deployment instructions, see our deployment guides for Bicep and Terraform.

Scope

Mission LZ has the following scope:

Hub and spoke networking intended to comply with SCCA controls
Predefined spokes for identity, operations, shared services, and workloads
Ability to create multiple, isolated workloads or team subscriptions
Remote access
Compatibility with SCCA compliance (and other compliance frameworks)
Security using standard Azure tools with sensible defaults
Azure Policy initiatives

Networking

Networking is set up in a hub and spoke design, separated by tiers: T0 (Identity and Authorization), T1 (Infrastructure Operations), T2 (DevSecOps and Shared Services), and multiple T3s (Workloads). Access control can be configured to allow separation of duties between all tiers.

Subscriptions

Most customers will deploy each tier to a separate Azure subscription, but multiple subscriptions are not required. A single subscription deployment is good for a testing and evaluation, or possibly a small IT Admin team.

Firewall

All network traffic is directed through the firewall residing in the Network Hub resource group. The firewall is configured as the default route for all the T0 (Identity and Authorization) through T3 (workload/team environments) resource groups as follows:

Name	Address prefix	Next hop type	Next hop IP address
default_route	0.0.0.0/0	Virtual Appliance	10.0.100.4

The default firewall configured for MLZ is Azure Firewall Premium. The Azure Firewall Premium SKU includes the IDPS feature necessary to satisfy the SCCA VDSS requirement. That being said, if you're deploying MLZ in an environment that does not have that requirement, you can optionally deploy Azure Firewall Standard by settings the firewallSkuTier parameter to Standard.

Presently, there are two firewall rules configured to ensure access to the Azure Portal and to facilitate interactive logon via PowerShell and Azure CLI, all other traffic is restricted by default. Below are the collection of rules configured for Azure Commercial and Azure Government clouds:

Rule Collection Priority	Rule Collection Name	Rule name	Source	Port	Protocol
100	AllowAzureCloud	AzureCloud	*	*	Any
110	AzureAuth	msftauth	*	Https:443	aadcdn.msftauth.net, aadcdn.msauth.net

To deploy Mission LZ using Azure Stack Hub and an F5 BIG-IP Virtual Edition instead of Azure Firewall Premium, there is an alternate repository with instructions found here.
