Data model for Microsoft Azure

This extension enriches iTop's CMDB by modelizing a set of objects commonly used within Microsoft Azure. Together with the Data collector for Azure, it enables administrators to automatically feed iTop with relevant and accurate Azure cloud computing information.

When installed on iTop, the extension creates a set of different classes that represent Azure objects. These classes are displayed in a specific dashboard that is accessible from a submenu of the standard CMDB overview menu. Classes are grouped by Azure families:

• General,
• Compute,
• Storage,
• Database,
• Container,
• Networking

None

The extension can only be installed on iTop 2.7.0 and above, including iTop 3, of course.

Use the Standard installation process for this extension. Note that it alters the “Overview” dashboard of the “Configuration Management” menu.

The extension brings configuration parameters that enable a direct access from an iTop Azure object to the detailed page of that object within Microsoft Azure environment where more information can be found.

Configuration

      'combodo-azure-datamodel' => array (
                'direct_access' => array (
                  'label' => 'Azure',
                  'url' => 'https://portal.azure.com/#@$azuretenant$/$azureid$/overview',
                  'icon' => 'fas fa-cloud-upload-alt',
                  'tooltip' => 'Lookup directly in Azure',
                ),
        ),

Parameter	Meaning	Default
label	Name of the action displayed in the “Other Actions” menu of objects	Azure
url	URL to access Azure details page for the object, based on the customer Tenant ID and the ID of the object within Azure	https://portal.azure.com/#@$azuretenant$/$azureid$/overview
icon	Font Awesome icon associated to the action label	fas fa-cloud-upload-alt, that appears as
tooltip	Tool tip associated to the action	Lookup directly in Azure

The link toward Microsoft described here above will appear in the “Other Actions” menu, as show here in the detailed screen of a Disk.

The Azure page will, of course, only open after appropriate credentials are given. It may look as follows:

The following chapters list and describe all Azure objects brought by the extension.

Locations defined in Azure are mapped to standard iTop location objects. For that purpose, the attribute “code” is added to the standard datamodel.

This class represents the organizational objects that can be defined within Microsoft Azure.

Azure Subscriptions are logical units of Azure services that are linked to an Azure account. They've been defined in iTop as a daughter class of the Contract class.

The “Discover objects” parameter enables the subscription to be discovered through the Data collector for Azure. When set to no, the collector will just ignore all objects from that belong to the subscription.

Azure Resource Groups are nothing but logical containers where Azure resources can be created and maintained.

Azure SKUs are typological elements that some azure classes refer to.

An Azure Virtual Machine (VM) is one of several types of on-demand, scalable computing resources that Azure offers.

Azure managed disks are block-level storage volumes that are managed by Azure and used with Azure Virtual Machines.

An Azure storage account provides a unique namespace for your Azure Storage data. It contains all of your Azure Storage data objects, including blobs, file shares, queues, tables, and disks.

In Azure, a database server is a logical construct that acts as a central administrative point for a collection of databases.

Azure Database for MariaDB is a relational database service in the Microsoft cloud. It is based on the MariaDB community edition (available under the GPLv2 license) database engine.

Azure Database for MySQL is a relational database service in the Microsoft cloud based on the MySQL Community Edition (available under the GPLv2 license) database engine

Azure Database for PostgreSQL is a relational database service in the Microsoft cloud based on the PostgreSQL open source relational database.

Azure Kubernetes Service is a managed container orchestration service based on the open source Kubernetes system, which is available on the Microsoft Azure public cloud.

An Azure App Service is an HTTP-based service for hosting web applications, REST APIs, and mobile back ends.

A private endpoint is a network interface that uses a private IP address from your virtual network. This network interface connects you privately and securely to a service that's powered by Azure Private Link. By enabling a private endpoint, you're bringing the service into your virtual network.

Azure Virtual Network (VNet) is the fundamental building block for your private network in Azure. It enables many types of Azure resources, such as Azure VMs, to securely communicate with each other, the internet, and on-premises networks.

A Network Interface Card (NIC) is an interconnection between a Virtual Machine and the underlying software network.

Network Interface Card IP Config host the IP configuration that can be assigned to a virtual machine's network interface card.

Azure Load Balancers evenly distribute load (incoming network traffic) across a group of back end resources or servers.

Load Balancer Frontend IP Configs host the IP configuration that can be assigned to a load balancer.

The virtual network data gateway helps you to connect from Microsoft Cloud services to your Azure data services within a VNet without the need of an on-premises data gateway. The VNet gateway securely communicates with the data source, executes queries, and transmits results back to the service.

Public IP addresses allow Internet resources to communicate inbound to Azure resources. Public IP addresses enable Azure resources to communicate to Internet and public-facing Azure services.

An Azure subnet (known as a public IP address prefix) is a reserved range of public IP addresses in Azure. Subnets are assigned from a pool of addresses in each Azure region.

Combodo Azure Datamodel extension accommodates iTop with TeemIp extension (aka IPAM for iTop) installed or not.

When TeemIp is not installed, all IP addresses or subnets attributes of Azure datamodel are just simple strings in IPv4 or IPv6 format.

When TeemIp is installed, all IP Addresses or subnets attributes become external keys toward IP Addresses or IP Subnets. Furthermore IP address or subnets set in Azure are transformed, through dedicated data synchro, into IP Addresses (IPv4 or IPv6) or IP Subnets (IPv4 or IPv6).

In such configuration, Azure Datamodel automatically alters IP Addresses and IP Subnets.

• IP Addresses have a new hidden attribute (“azureip”) that defines if a given IP has been created from Azure data collector or not.
• Their “CIs” tab will automatically display the list of Azure CIs pointing to them.

• IP Subnets have a new attribute (“azuresubnet_id”) that points to the Azure subnet carrying the IP Subnet.
