How it works / How to use it

Create a Private Endpoint for a supported service, configure DNS, and manage access via NSGs. Integrate with services like Storage, SQL, and Key Vault.

az network private-endpoint create --name myEndpoint --resource-group myGroup --vnet-name myVNet --subnet mySubnet --private-connection-resource-id /subscriptions/{sub}/resourceGroups/{rg}/providers/Microsoft.Storage/storageAccounts/{account} --group-ids blob

Practice Steps

1. Create a Private Endpoint for a Storage Account.
2. Configure DNS for name resolution.
3. Test private connectivity from a VM.
4. Restrict public access on the service.

Mini-Project or Use Case

Secure database traffic for a web app using Private Link and custom DNS.

Common Mistake

Not updating DNS settings, causing connectivity failures.

What is Azure Automation?

Azure Automation is a cloud-based service for automating repetitive tasks, orchestrating processes, and managing configuration across Azure and hybrid environments. It supports runbooks, update management, DSC, and hybrid workers.

Why it matters

Automation boosts efficiency, reduces human error, and enforces consistency. Azure Specialists use it for patching, resource cleanup, compliance, and complex workflows.

How it works / How to use it

Create Automation Accounts, author runbooks (PowerShell, Python), and schedule jobs. Integrate with webhooks and hybrid workers for on-premises automation.

Start-AzAutomationRunbook -AutomationAccountName "myAccount" -Name "CleanupResources" -ResourceGroupName "myGroup"

Practice Steps

1. Create an Automation Account.
2. Write a PowerShell runbook to clean up unused resources.
3. Schedule and monitor jobs.
4. Integrate with alerts for automated remediation.

Mini-Project or Use Case

Automate VM patching and resource lifecycle management for a production environment.

Common Mistake

Not handling runbook errors, resulting in incomplete or failed automation jobs.

What is Event Grid?

Azure Event Grid is an eventing service for managing event-based architectures. It enables reliable, scalable event distribution between services and applications in real time.

Why it matters

Event Grid decouples producers and consumers, making Azure solutions more scalable and responsive. Specialists use it for automation, microservices, and integration scenarios.

How it works / How to use it

Configure event sources (Storage, IoT Hub, custom apps), define event subscriptions, and route events to endpoints (Functions, Logic Apps, WebHooks).

az eventgrid topic create --name myTopic --resource-group myGroup
az eventgrid event-subscription create --topic-name myTopic --resource-group myGroup --endpoint https://myfunction.azurewebsites.net/runtime/webhooks/EventGrid?code=... 

Practice Steps

1. Create an Event Grid Topic.
2. Subscribe an Azure Function as an endpoint.
3. Trigger events and monitor delivery.
4. Implement dead-lettering for failed events.

Mini-Project or Use Case

Build an image processing pipeline triggered by blob uploads using Event Grid and Functions.

Common Mistake

Not handling event delivery failures, leading to lost or unprocessed events.

What are Advanced Logic Apps?

Advanced Logic Apps involve complex, multi-stage workflows, custom connectors, error handling, and integration with on-premises systems. They support enterprise-scale automation and hybrid integration.

Why it matters

Azure Specialists leverage advanced features to automate business-critical processes, integrate legacy systems, and ensure resilience and compliance.

How it works / How to use it

Use advanced control flows (conditions, loops), custom connectors, and on-premises data gateways. Implement robust error handling and monitoring.

# Example: Adding a custom connector in Logic Apps
{
  "connector": { ... }
}

Practice Steps

1. Implement a multi-stage approval workflow.
2. Create a custom connector for a legacy system.
3. Configure error handling and retries.
4. Monitor and troubleshoot runs.

Mini-Project or Use Case

Integrate SAP with Azure services using Logic Apps, custom connectors, and on-premises gateways.

Common Mistake

Not implementing robust error handling, leading to silent workflow failures.

What is API Management?

Azure API Management (APIM) is a platform for publishing, securing, transforming, and monitoring APIs. It provides a gateway, developer portal, analytics, and policy enforcement.

Why it matters

APIM enables secure, scalable API exposure and governance. Azure Specialists use it to manage APIs for internal, partner, or public consumption.

How it works / How to use it

Import APIs, configure policies (rate limiting, transformation), secure with OAuth or keys, and monitor usage via analytics.

az apim create --name myAPIM --resource-group myGroup --publisher-email [email protected] --location eastus

Practice Steps

1. Create an APIM instance.
2. Import an OpenAPI definition.
3. Apply rate limiting and transformation policies.
4. Publish APIs to the developer portal.

Mini-Project or Use Case

Expose a backend API to partners securely with OAuth and custom policies.

Common Mistake

Not securing APIs, leading to unauthorized access or abuse.
