Managed identity integration in Azure - Step-by-Step Execution

Process Flow - Managed identity integration

Enable Managed Identity on Azure Resource

↓

Azure assigns Identity to Resource

↓

Resource requests Token from Azure AD

↓

Azure AD validates and issues Token

↓

Resource uses Token to access Azure Service

↓

Azure Service validates Token and grants access

This flow shows how an Azure resource with managed identity requests and uses a token to access another Azure service securely.

Execution Sample

Azure

1. Enable managed identity on VM
2. VM requests token from Azure AD
3. Azure AD issues token
4. VM uses token to access Key Vault
5. Key Vault validates token and allows access

This sequence shows a VM using its managed identity to get a token and access a Key Vault securely without credentials.

Process Table

Step	Action	Request/Response	Result
1	Enable managed identity on VM	N/A	VM assigned a system-assigned managed identity
2	VM requests token from Azure AD	Request token for Key Vault access	Azure AD validates VM identity
3	Azure AD issues token	Token issued with access permissions	VM receives access token
4	VM uses token to access Key Vault	Token presented to Key Vault	Key Vault validates token
5	Key Vault grants access	Access granted based on token	VM can securely read secrets
6	End	No further requests	Process complete

💡 Process stops after VM successfully accesses Key Vault using managed identity token

Status Tracker

Variable	Start	After Step 1	After Step 2	After Step 3	After Step 4	Final
VM Identity	None	Assigned	Used to request token	Token received	Token used to access Key Vault	Access granted
Token	None	None	Requested	Issued	Presented	Validated

Key Moments - 3 Insights

Why doesn't the VM need to store any credentials to access Key Vault?

Because the VM uses its managed identity to request a token from Azure AD dynamically (see execution_table steps 2 and 3), so no credentials are stored on the VM.

What ensures that the token the VM receives is valid and secure?

Azure AD validates the VM's managed identity before issuing the token (execution_table step 2), ensuring only authorized resources get tokens.

How does Key Vault know to trust the token presented by the VM?

Key Vault validates the token against Azure AD's issued tokens (execution_table step 4), confirming the token's authenticity and permissions.

Visual Quiz - 3 Questions

Look at the execution table, at which step does the VM receive the access token?

A Step 2

B Step 3

C Step 4

D Step 5

💡 Hint

Check the 'Result' column for when the VM receives the token.

At which step does Key Vault validate the token presented by the VM?

A Step 3

B Step 5

C Step 4

D Step 6

💡 Hint

Look for the step where Key Vault checks the token in the 'Action' column.

If the managed identity was not enabled on the VM, what would happen at Step 2?

A Azure AD would reject the token request

B VM would still get a token

C Key Vault would grant access anyway

D VM would access Key Vault without token

💡 Hint

Refer to the 'Request/Response' and 'Result' columns at Step 2 about token validation.

Concept Snapshot

Managed Identity Integration in Azure:
- Enable managed identity on resource (e.g., VM)
- Resource requests token from Azure AD
- Azure AD validates and issues token
- Resource uses token to access Azure services
- Services validate token and grant access
- No credentials stored on resource, secure access

Full Transcript

Managed identity integration allows Azure resources like virtual machines to securely access other Azure services without storing credentials. First, you enable a managed identity on the resource. Then, the resource requests an access token from Azure Active Directory (Azure AD). Azure AD validates the resource's identity and issues a token. The resource uses this token to access services like Azure Key Vault. The service validates the token before granting access. This process ensures secure, credential-free access between Azure services.
