You are going to build an automated process in order to speed up the integration and testing of your models, to make a robust development and testing process.
This process needs to have access to the objects in your ML workspace, and it should work in the background, requiring no user interaction.
Which authentication method is recommended to use in most cases?
Click on the arrows to vote for the correct answer
A. B. C. D.Answer: C.
Option A is incorrect because the Role Based Access Control (RBAC) is used to limit and control the scope granted to an identity over a resource.
It helps you manage who has access to Azure resources, and what they can do with those resources.
It is used together with authentication workflows like interactive, service principal and managed identity.
Option B is incorrect because managed identity is only supported when using Azure ML SDK from an Azure virtual machine.
Option C is CORRECT because using service principals is the preferred way of authentication when there is a need to connect to the ML workspace without individual user accounts, within automated processes.
Option D is incorrect because the interactive way of authentication is used for user-based authentication, and it requires direct authentication from users, i.e.
it is not suitable for automated processes.
Reference:
For an automated process to access the objects in an Azure Machine Learning workspace without any user interaction, it requires an authentication method that does not require human intervention. Here are the details of the recommended authentication methods:
A. Role-Based Access Control (RBAC): This authentication method allows you to manage access to Azure resources based on roles. RBAC grants access to Azure resources to users, groups, and applications based on their roles in an organization. This is a secure method to control access to resources. However, RBAC requires the user to authenticate with Azure Active Directory before accessing the workspace.
B. Managed Identity: This authentication method provides an Azure service with an automatically managed identity in Azure Active Directory. This identity can be used to authenticate with any service that supports Azure AD authentication. Using a managed identity, you don't need to store credentials or secrets in your code. This is a secure method of authentication that requires no user interaction.
C. Service Principal: This authentication method allows you to authenticate with Azure resources using a client ID and client secret or a certificate. A service principal is essentially an identity for an application. This method is ideal for automated processes that require access to Azure resources without human intervention.
D. Interactive: This authentication method requires user interaction, which means it's not suitable for an automated process that requires no user intervention.
Based on the above, the recommended authentication method for an automated process that requires access to objects in an ML workspace without user interaction is Managed Identity. This method provides a secure and hassle-free way of authentication that eliminates the need for storing credentials or secrets in code.
