Personal Server Hyperlink TOP

A Private Endpoint is the fundamental building block for private link in Azure. It enables Azure resources, like Virtual Machines (VMs), to communicate privately with private link resources. In this article, you will learn how to use the Azure portal to create a VM in an Azure Virtual Network and an Azure Database for PostgreSQL Single server with an Azure private endpoint.

Personal Server Hyperlink

The private link feature is only available for Azure Database for PostgreSQL servers in the General Purpose or Memory Optimized pricing tiers. Ensure the database server is in one of these pricing tiers.

In this how-to, you created a VM on a virtual network, an Azure Database for PostgreSQL - Single server, and a private endpoint for private access. You connected to one VM from the internet and securely communicated to the PostgreSQL server using Private Link. To learn more about private endpoints, see What is Azure private endpoint.

Azure Private Link allows you to securely link Azure PaaS services to your virtual network using private endpoints. For many services, you just set up an endpoint per resource. This means you can connect your on-premises or multi-cloud servers with Azure Arc and send all traffic over an Azure ExpressRoute or site-to-site VPN connection instead of using public networks.

Azure Arc Private Link Scope connects private endpoints (and the virtual networks they're contained in) to an Azure resource, in this case Azure Arc-enabled servers. When you enable any one of the Azure Arc-enabled servers supported VM extensions, such as Azure Automation Update Management or Azure Monitor, those resources connect other Azure resources. Such as:

Connectivity to any other Azure resource from an Azure Arc-enabled server requires configuring Private Link for each service, which is optional, but recommended. Azure Private Link requires separate configuration per service.

The Private Endpoint on your VNet allows it to reach Azure Arc-enabled servers endpoints through private IPs from your network's pool, instead of using to the public IPs of these endpoints. That allows you to keep using your Azure Arc-enabled servers resource without opening your VNet to outbound traffic not requested.

Deploy an Azure Arc Private Link Scope, which controls which machines or servers can communicate with Azure Arc over private endpoints and associate it with your Azure virtual network using a private endpoint.

Azure Arc-enabled servers integrate with several Azure services to bring cloud management and governance to your hybrid machines or servers. Most of these services already offer private endpoints, but you need to configure your firewall and routing rules to allow access to Azure Active Directory and Azure Resource Manager over the internet until these services offer private endpoints.

Optionally, you can require every Azure Arc-enabled machine or server associated with this Azure Arc Private Link Scope to send data to the service through the private endpoint. To do so, check the box for Allow public network access so machines or servers associated with this Azure Arc Private Link Scope can communicate with the service over both private or public networks. You can change this setting after creating the scope if you change your mind.

If you choose No and prefer to manage DNS records manually, first complete setting up your Private Link - including this Private Endpoint and the Private Scope configuration. Then, configure your DNS according to the instructions in Azure Private Endpoint DNS configuration. Make sure not to create empty records as preparation for your Private Link setup. The DNS records you create can override existing settings and impact your connectivity with Azure Arc-enabled servers.

Your on-premises machines or servers need to be able to resolve the private link DNS records to the private endpoint IP addresses. How you configure this depends on whether you're using Azure private DNS zones to maintain DNS records, or if you're using your own DNS server on-premises and how many servers you're configuring.

If you set up private DNS zones for Azure Arc-enabled servers and Guest Configuration when creating the private endpoint, your on-premises machines or servers need to be able to forward DNS queries to the built-in Azure DNS servers to resolve the private endpoint addresses correctly. You need a DNS forwarder in Azure (either a purpose-built VM or an Azure Firewall instance with DNS proxy enabled), after which you can configure your on-premises DNS server to forward queries to Azure to resolve private endpoint IP addresses.

From the left-hand pane, select DNS configuration to see a list of the DNS records and corresponding IP addresses you'll need to set up on your DNS server. The FQDNs and IP addresses will change based on the region you selected for your private endpoint and the available IP addresses in your subnet.

Follow the guidance from your DNS server vendor to add the necessary DNS zones and A records to match the table in the portal. Ensure that you select a DNS server that is appropriately scoped for your network. Every machine or server that uses this DNS server now resolves the private endpoint IP addresses and must be associated with the Azure Arc Private Link Scope, or the connection will be refused.

If you're only planning to use Private Links to support a few machines or servers, you may not want to update your entire network's DNS configuration. In this case, you can add the private endpoint hostnames and IP addresses to your operating systems Hosts file. Depending on the OS configuration, the Hosts file can be the primary or alternative method for resolving hostname to IP address.

Add the private endpoint IPs and hostnames as shown in the table from step 3 under Manual DNS server configuration. The hosts file requires the IP address first followed by a space and then the hostname.

Add the private endpoint IPs and hostnames as shown in the table from step 3 under Manual DNS server configuration. The hosts file asks for the IP address first followed by a space and then the hostname.

The minimum supported version of the Azure Arc-connected machine agent with private endpoint is version 1.4. The Azure Arc-enabled servers deployment script generated in the portal downloads the latest version.

On the Add servers with Azure Arc page, select either the Add a single server or Add multiple servers depending on your deployment scenario, and then select Generate script.

If you selected Add multiple servers, on the Authentication page, select the service principal created for Azure Arc-enabled servers from the drop-down list. If you have not created a service principal for Azure Arc-enabled servers, first review how to create a service principal to familiarize yourself with permissions required and the steps to create one. Select Next: Tags to continue.

After downloading the script, you have to run it on your machine or server using a privileged (administrator or root) account. Depending on your network configuration, you may need to download the agent from a computer with internet access and transfer it to your machine or server, and then modify the script with the path to the agent.

Network traffic from the Azure Connected Machine agent to Azure Active Directory and Azure Resource Manager will continue to use public endpoints. If your server needs to communicate through a proxy server to reach these endpoints, configure the agent with the proxy server URL before connecting it to Azure. You may also need to configure a proxy bypass for the Azure Arc services if your private endpoint is not accessible from your proxy server.

Check your on-premises DNS server(s) to verify it is either forwarding to Azure DNS or is configured with appropriate A records in your private link zone. These lookup commands should return private IP addresses in your Azure virtual network. If they resolve public IP addresses, double check your machine or server and network's DNS configuration.

If you are having trouble onboarding a machine or server, confirm that you've added the Azure Active Directory and Azure Resource Manager service tags to your local network firewall. The agent needs to communicate with these services over the internet until private endpoints are available for these services.

A hyperlink is a unidirectional (moving or operating in a single direction) link in an electronic document. Hyperlinks can connect two different documents as well as various sections in the same document. A text enriched with hyperlinks is called a hypertext.

The most widespread hypertext system in the world is the world wide web (also known as 'web' or 'www'). On the web, hyperlinks are implemented using the markup language HTML to link web pages and other resources together. In this article, we concentrate on hyperlinks in web documents and present their structure, properties, and give some examples of their use.

Hyperlinks are links in e-documents and are the foundation of the networked structure that is the world wide web. Clicking on a hyperlink enables you to jump between different text elements in a document or between different websites and, therefore, a non-linear organization of content.

In HTML documents, hyperlinks are implemented using and elements. While the element defines the position of a hyperlink in the content area (body) of an HTML document, the element in the header area (head) is used to define relationships with other documents and resources.

In the following paragraph, we concentrate on the element, in other words on hyperlinks in the HTML body. They are visible to website visitors, can be clicked on, and belong to the central navigation tools of the world wide web, just as the address bar in the browser or the input fields of search engines. 041b061a72
