Azure Monitor Private Link Scope is a powerful feature that allows you to control access to your Azure Monitor resources.
With Private Link Scope, you can create a boundary around your Azure Monitor resources and limit access to only the resources you want to share with others. This helps to improve security and compliance.
You can create multiple Private Link Scopes to organize your resources in different ways, such as by project or by department. This makes it easier to manage access to your resources and ensure that only authorized users can view them.
Private Link Scope is integrated with Azure Active Directory (Azure AD), which means you can use Azure AD groups to manage access to your resources. This simplifies the process of managing access and reduces the risk of errors.
What is a Private Link?
A Private Link is a technology that allows you to connect your network to Azure Monitor without exposing it to the public internet. It provides a secure way to access Azure Monitor resources.
By using Azure Private Link, you can connect your networks to Azure Monitor, which is a crucial step in setting up a Private Link Scope. This connection is established through a Private Endpoint, which is a network interface that connects your network to Azure Monitor.
A Private Link Scope is a feature that connects a Private Endpoint to a set of Azure Monitor resources, such as Log Analytics and Application Insights workspaces. This connection is private and secure, ensuring that your monitoring data is only accessed through authorized networks.
Here are the key benefits of using a Private Link:
- Connect privately to Azure Monitor without opening up any public network access
- Ensure your monitoring data is only accessed through authorized private networks
- Prevent data exfiltration from your private networks by defining specific Azure Monitor resources that connect through your private endpoint
- Securely connect your private on-premises network to Azure Monitor using ExpressRoute and Private Link
- Keep all traffic inside the Microsoft Azure backbone network
In summary, a Private Link is a secure way to connect your network to Azure Monitor, and a Private Link Scope is a feature that connects a Private Endpoint to a set of Azure Monitor resources.
Creating and Managing Private Link
Creating a private link scope in Azure Monitor is a straightforward process. You can use the command `az monitor private-link-scope create` to create a private link scope resource.
To configure your private link, you'll need to design your Azure Private Link setup, which involves defining the resources that will connect through your private endpoint.
You can list all your monitor private link scope resources using the command `az monitor private-link-scope list`. This command also allows you to specify the total number of items to return in the output.
The `az monitor private-link-scope list` command also includes a token to resume pagination, which is useful if you have a large number of resources to manage.
Here are the next steps to take after creating your private link scope:
- Design your Azure Private Link setup.
- Learn how to configure your private link.
- Learn about private storage for custom logs and customer-managed keys.
Private Link Scope
A Private Link Scope is a way to connect a Private Endpoint to a set of Azure Monitor resources. This allows you to connect privately to Azure Monitor without opening up any public network access.
Azure Monitor Private Link Scope provides several advantages, including ensuring your monitoring data is only accessed through authorized private networks, preventing data exfiltration from your private networks, and securely connecting your private on-premises network to Azure Monitor using ExpressRoute and Private Link.
Here are some key benefits of using a Private Link Scope:
- Connects privately to Azure Monitor without opening up any public network access
- Ensures monitoring data is only accessed through authorized private networks
- Prevents data exfiltration from private networks
- Secures private on-premises network connection to Azure Monitor using ExpressRoute and Private Link
- Keeps all traffic inside the Microsoft Azure backbone network
Private Link Scope
A Private Link Scope is a way to connect a Private Endpoint to a set of Azure Monitor resources, such as Log Analytics and Application Insights workspaces.
This setup provides several advantages, including connecting privately to Azure Monitor without opening up any public network access and ensuring your monitoring data is only accessed through authorized private networks.
You can use Azure Private Link to connect networks to Azure Monitor, design your Private Link setup, and configure your Private Link.
A Private Link Scope is a necessary component for certain services, including Azure Monitor and Arc, which don't support direct Private Endpoint connections.
Instead, you use a Private Link Scope, which associates a Private Endpoint with specific Log Analytics and Application Insight workspaces.
This setup allows Virtual Machines in Virtual Networks to communicate with the private IP address of the private endpoint, and traffic is sent using private IP addresses to the destination Log Analytics workspace.
An Azure Monitor Private Link Scope (AMPLS) is a set of Azure Monitor resources that define the boundaries of your monitoring network.
It uses private IPs, runs on the Azure backbone, controls which Azure Monitor resources can be reached, and controls network access to your Azure Monitor resources.
Here are some key aspects of an AMPLS:
- Uses private IPs: The private endpoint on your virtual network allows it to reach Azure Monitor endpoints through private IPs from your network's pool.
- Runs on the Azure backbone: Traffic from the private endpoint to your Azure Monitor resources will go over the Azure backbone and not be routed to public networks.
- Controls which Azure Monitor resources can be reached: Configure whether to allow traffic only to Private Link resources or to both Private Link and non-Private-Link resources outside of the AMPLS.
- Controls network access to your Azure Monitor resources: Configure each of your workspaces or components to accept or block traffic from public networks, potentially using different settings for data ingestion and query requests.
Other Regions
Azure Private Link allows for cross-regional connections, which is especially useful if your infrastructure is hosted in a different region than where Grafana is hosted.
This means you can still benefit from Private Link even if your infrastructure and Grafana are in different Azure regions.
In fact, this cross-regional support is a key feature of Azure Private Link, enabling you to connect your resources across different regions.
