Azure Functions

Question 1

What is Azure Functions often referred to as?

Answer 1

Azure Functions is often referred to as serverless event-driven code execution.

Question 2

How does Azure Functions compare to other platform as a service (PaaS) services?

Answer 2

Azure Functions is an extreme version of PaaS with practically zero management overhead, running only when triggered.

Question 3

What is the key difference between Azure Functions and services like App Service?

Answer 3

Azure Functions applications run only when triggered and then shut down, unlike continuous running applications in App Service.

Question 4

What is the role of Azure Functions in handling events like image uploads?

Answer 4

Azure Functions can automatically trigger actions, such as resizing images upon upload events, based on defined triggers.

Question 5

What is the advantage of using Azure Functions in terms of resource utilization?

Answer 5

Azure Functions only consume resources when triggered, leading to cost savings as resources are not continuously running.

Question 6

How does Azure Functions handle scalability without manual configuration?

Answer 6

Azure Functions automatically scale based on demand without the need for manual scaling configurations.

Question 7

What is the main benefit of using Azure Functions for event-driven scenarios?

Answer 7

Azure Functions simplify infrastructure management, as developers only need to focus on deploying code that responds to specific triggers.

Question 8

What term is often used to describe Azure Functions and similar serverless services?

Answer 8

Azure Functions and similar services are often described as functions as a service (FaaS) due to their focus on executing specific functions triggered by events.

Question 9

How does Azure Functions handle failures without affecting other functions?

Answer 9

Azure Functions isolate failures to individual functions, ensuring that failures in one function do not impact the performance of other functions.

Question 10

What are the key takeaways about Azure Functions?

Answer 10

zure Functions are event-driven, serverless compute services that scale automatically, have minimal management overhead, and are cost-effective due to resource utilization only when triggered.
