  "account": "Part 3 of the Azure Integration Services interview preparation focuses on Managed Identity, Key Vault, VNet, Private Endpoints, NSGs, RBAC, and Token Validation. Managed Identity provides an Azure resource with its own automatically managed identity in Azure AD, which enables it to authenticate to other Azure services without the need for storing, rotating, or managing passwords, connection strings, or certificates. There are two types of Managed Identity: system-assigned, tied to a specific resource's lifecycle, and user-assigned, a standalone Azure resource that can be assigned to multiple resources.\n\nTo enable system-assigned identity, you can use the Azure Portal, modify the Function App's identity in the portal, and save the changes. In C#, the DefaultAzureCredential automatically discovers and uses the Managed Identity when running in Azure, without the need for a connection string or client secret.\n\nManaged Identity grants access through Azure RBAC, eliminating the need for stored keys. For example, granting the Key Vault Secrets User role to the Function App's Managed Identity allows it to access secrets in Key Vault.\n\nKey Vault is a managed service for securely storing secrets, encryption keys, and certificates. It complements Managed Identity by providing a secure location for secrets that cannot be eliminated by Managed Identity. For instance, partner API keys, third-party webhook signing secrets, and credentials for systems outside Azure should be stored in Key Vault.\n\nVNet Integration enables Azure PaaS services to send their outbound traffic through a Virtual Network, reducing their exposure to the public internet. This feature, combined with Managed Identity, allows Function Apps, Logic Apps Standard, and App Service to communicate with resources locked down to a specific private network.",
  "summary": "Part 1 covered the messaging services - Service Bus, Storage Queues, Event Hub, Event Grid. Part 2 covered the orchestration layer that processes what those services move - Logic Apps, Function Apps, Durable Functions. Neither part addressed a question every panel interview eventually asks: how does any of this actually get secured. This part covers exactly that, and deliberately ties every…",
