Welcome to our complete guide on Azure Managed Identities. In this section, we will dive into the concept of managed identities and how they can enhance the security of your cloud-native applications.
Azure Managed Identities provide a solution for securely managing credentials, keys, certificates, and secrets in cloud-native applications. Storing these sensitive details directly within application code can pose security risks. Managed identities remove the need to handle this information manually by automatically managing it within Azure Active Directory (AD) when connected to resources that support AD authentication. There are two types of managed identities: system-assigned and user-assigned.
System-assigned managed identities are enabled on specific Azure services and are created as a part of the service instance. These identities are tied to the lifecycle of the service instance and are automatically removed when the service is deleted.
User-assigned managed identities are created separately as a standalone Azure resource and can be assigned to multiple Azure services or instances. These identities have an independent lifecycle and are not deleted when the associated resource is deleted.
Using managed identities offers several benefits, including enhanced security as credentials are not accessible, the ability to authenticate to any Azure resource supporting AD authentication, and no additional charges. Managed identities can be used to obtain Azure AD tokens, and Azure handles credential rolling to prevent password leaks.
To implement Azure managed identities, one needs to request Azure Resource Manager to enable or create a managed identity, configure the managed identity, assign an appropriate role to the managed identity on the required resource using IAM, and then use the managed identity to request access tokens for resources that support Azure AD authentication.
Managed identities can be managed using various tools such as the Azure portal, Azure CLI, PowerShell, and REST APIs. The complete list of Azure services that support managed identities can be found on the Azure website. It’s important to note that managed identities, whether system-assigned or user-assigned, are a special kind of service principal used only with Azure resources.
In summary, Azure Managed Identities provide a secure and efficient way to manage credentials, keys, and secrets within cloud-native applications. They eliminate the need to store sensitive information in application code, enhance security, and allow for easy authentication to Azure resources. Both system-assigned and user-assigned managed identities have their own use cases and benefits, providing flexibility and scalability for different scenarios.
