App Service and Serverless Computing Flashcards
Microsoft Azure Developer Associate AZ-204 Flashcards
| Front | Back |
| How does Autoscale work in Azure App Service | Based on rules or metrics like CPU usage to handle traffic surges. |
| What are bindings in Azure Functions | Simplify input and output by automatically handling data sources and services. |
| What are Durable Functions | An extension of Azure Functions for stateful workflows and orchestration. |
| What are the deployment options for Azure App Service | Options include Azure DevOps, GitHub Actions, and FTP. |
| What are the pricing tiers in App Service Plans | Free, Shared, Basic, Standard, Premium, and Isolated. |
| What does durable mean in Durable Functions | Ensures the workflow execution maintains its state across restarts or failures. |
| What does the term "serverless" mean | Computing without managing infrastructure, automatically scaling based on demand. |
| What is a Timer Trigger in Azure Functions | Executes a function based on a specified time schedule. |
| What is an Activity Function in Durable Functions | A reusable function that performs specific tasks within a larger workflow. |
| What is an Endpoint in Azure App Service | A URL for users or APIs to connect to a hosted app or service. |
| What is an HTTP Trigger in Azure Functions | Executes a function in response to an HTTP request. |
| What is Azure App Service | A cloud-based platform for building, deploying, and scaling web applications and APIs. |
| What is scaling in Azure Functions | Automatically adjusting resources to handle workloads based on demand. |
| What is the advantage of using Azure Functions for processing events | High scalability and cost efficiency tied directly to usage. |
| What is the benefit of using Azure App Service for hosting web applications | Built-in load balancing, scaling, and security. |
| What is the benefit of using Azure Functions over traditional web services | Reduced cost and simplified deployment due to serverless architecture. |
| What is the best use case for Durable Functions | Complex workflows that require state management and coordination. |
| What is the difference between Consumption Plan and Premium Plan for Azure Functions | Consumption Plan scales automatically and is billed per execution, while Premium Plan offers dedicated instances and advanced scaling. |
| What is the difference between Stateless and Stateful Functions | Stateless functions don't retain state between executions, while stateful functions manage and persist state. |
| What is the Function App | The container for hosting one or more Azure Functions. |
| What is the main benefit of Azure Functions | Allow you to write event-driven, serverless code without managing infrastructure. |
| What is the purpose of an App Service Plan | Defines the compute resources and pricing tier for an App Service. |
| What is the purpose of an orchestration function in Durable Functions | To coordinate the execution of activity functions and handle their output. |
| What programming languages does Azure App Service support | .NET, Node.js, PHP, Python, Ruby, and Java. |
| What triggers can be used with Azure Functions | HTTP requests, timers, events, queues, and blobs. |
This deck covers the fundamentals of Azure App Service for web applications and serverless solutions using Azure Functions and Durable Functions.
