Q & A

What is serverless computing?

Serverless computing is a cloud hosting model where the infrastructure is abstracted away. Users deploy their applications or use pre-built products, and the cloud provider like Microsoft scales the infrastructure to match demand without the user managing the servers.

What are the three main serverless services discussed in the script?

The three main serverless services discussed are Azure Functions, Azure Logic Apps, and Azure Event Grid.

How does Azure Functions enable serverless computing?

Azure Functions allows customers to build and host small pieces of code as web services. It abstracts the server management, automatically scaling the code across multiple servers as needed and supporting popular languages and frameworks.

What is Azure Logic Apps and how does it facilitate workflow building?

Azure Logic Apps is a service that enables users to build workflows visually, representing business scenarios and cross-application integrations. It supports simple step-by-step workflows, complex scenarios with conditions, loops, and parallel runs, and integrates with over 200 connectors for various services.

How can Azure Logic Apps be triggered?

Azure Logic Apps can be triggered by various events such as web requests, emails, Office 365 events, or activities within Azure subscriptions.

What is a demo shown in the script for Azure Logic Apps?

The demo in the script shows how to create a workflow in Azure Logic Apps that triggers when new files are added to Azure Blob Storage and sends an email notification about the new blob using the Outlook connector.

What is Azure Event Grid and its primary function?

Azure Event Grid is a serverless event routing service that routes messages or events from various Azure services and custom applications to different subscribers, ensuring the successful delivery of these messages without the need to manage the underlying infrastructure.

How does Azure Event Grid support event-based applications?

Azure Event Grid supports event-based applications by allowing publishers to send events and subscribers to receive them, using a publish-subscribe model. It's designed for near real-time applications and can react to changes in Azure services and subscriptions.

What kind of events does Azure Event Grid support from Azure subscriptions?

Azure Event Grid supports a wide range of built-in events from Azure subscriptions, such as virtual machine status changes, rescaling of virtual machines, and provisioning of other resources.

What additional resources are available for learning more about the discussed serverless services?

Additional resources, including tutorials for Azure Logic Apps, Function Apps, and Event Grid, can be found under episode 17 on the presenter's website.

How can viewers support the channel presenting the serverless computing episode?

Viewers can support the channel by subscribing, liking, commenting, and checking out additional materials on the presenter's website.
