Describe in detail In the context of Azure services, public and private endpoints refer to the network connectivity options available for accessing those services.
A public endpoint refers to a service that is accessible over the public Internet. These endpoints typically have a public IP address and a domain name associated with them, which can be accessed from anywhere on the Internet. Examples of services that typically use public endpoints include web servers, APIs, and DNS servers.
On the other hand, a private endpoint refers to a service that is only accessible within a virtual network, and not over the public Internet. These endpoints typically have a private IP address within the virtual network, and are accessed using a private DNS zone. Private endpoints are useful for accessing services that need to be kept secure and isolated from the public Internet, such as databases and storage accounts.
In Azure, both public and private endpoints can be used to access various services. For example, Azure App Service, which is a platform for hosting web applications, can be accessed through a public endpoint by default. However, customers can also configure private endpoints for App Service by using Azure Private Link, which enables private connectivity to the service from within a virtual network.
Similarly, Azure Storage accounts can be accessed through a public endpoint by default, but customers can also configure private endpoints for storage accounts using Azure Private Link. Private endpoints for storage accounts enable customers to access their data securely from within a virtual network, without exposing it to the public Internet.
Public and private endpoints provide different connectivity options for accessing Azure services, depending on the specific requirements of the service and the customer’s security and networking needs. Public endpoints are accessible over the public Internet and typically have a public IP address, while private endpoints are accessible only within a virtual network and use a private IP address.
Public and private endpoints are two different network connectivity options available for accessing services in Azure.
Public endpoints refer to services that are accessible over the public Internet. These endpoints typically have a public IP address and a domain name associated with them, which can be accessed from anywhere on the Internet. Public endpoints are useful for services that need to be accessible to a wide range of users, such as web servers, APIs, and DNS servers.
Private endpoints, on the other hand, refer to services that are only accessible within a virtual network, and not over the public Internet. These endpoints typically have a private IP address within the virtual network, and are accessed using a private DNS zone. Private endpoints are useful for accessing services that need to be kept secure and isolated from the public Internet, such as databases and storage accounts.
The key differences between public and private endpoints can be summarized as follows:
- Accessibility: Public endpoints are accessible over the public Internet, while private endpoints are only accessible within a virtual network.
- Security: Public endpoints are more exposed to security risks, as they are accessible to anyone on the Internet. Private endpoints, on the other hand, provide a more secure way to access services by restricting access to only those who are within the virtual network.
- IP Address: Public endpoints typically have a public IP address, while private endpoints have a private IP address within the virtual network.
- DNS: Public endpoints typically use a public DNS zone to resolve their domain name, while private endpoints use a private DNS zone within the virtual network.

Compare security of public and private endpoints.
Public and private endpoints have different security implications, primarily because public endpoints are exposed to the public Internet, while private endpoints are only accessible within a virtual network.
Public endpoints are more vulnerable to security threats because they are accessible to anyone on the Internet. Hackers and malicious actors can easily scan the Internet for vulnerable services and exploit them to gain unauthorized access to sensitive data or systems. Therefore, it’s crucial to secure public endpoints by implementing strong authentication and access controls, as well as by regularly applying security updates and patches.
On the other hand, private endpoints provide a more secure way to access services by restricting access to only those who are within the virtual network. This significantly reduces the attack surface and makes it harder for hackers to gain unauthorized access to the service. However, it’s still important to implement strong authentication and access controls for private endpoints, as well as to regularly monitor and audit access to the service.
It’s worth noting that private endpoints are not immune to security threats. If an attacker gains access to a virtual network, they may be able to access the private endpoints within that network. Therefore, it’s important to secure the virtual network itself by implementing network security groups, firewalls, and other security measures.
Public and private endpoints have different security implications, with public endpoints being more vulnerable to external attacks, while private endpoints provide a more secure way to access services within a virtual network. However, regardless of the endpoint type, it’s important to implement strong security measures to protect the service and its data from potential threats.
