Why serverless patterns matter in GCP - Quick Recap

Recall & Review

beginner

What does 'serverless' mean in cloud computing?

Serverless means you don't manage servers directly. The cloud provider runs and scales your code automatically.

beginner

Why do serverless patterns help developers?

They let developers focus on writing code without worrying about infrastructure, making apps faster and cheaper to build.

How does serverless improve scalability?

Serverless automatically adjusts resources up or down based on demand, so apps handle traffic smoothly without manual setup.

intermediate

What is a common serverless pattern for event-driven apps?

Using cloud functions triggered by events like file uploads or messages to run code only when needed.

beginner

How do serverless patterns reduce costs?

You pay only for the compute time your code uses, not for idle servers, which saves money especially for variable workloads.

What is a key benefit of serverless computing?

A You must configure all servers manually

B You pay for servers even when idle

C Servers run only on your local machine

D No need to manage servers

Serverless means the cloud provider manages servers, so you don't have to.

How does serverless handle scaling?

A Does not support scaling

B Requires manual server setup for scaling

C Automatically adjusts resources based on demand

D Scales only during business hours

Serverless platforms automatically scale your app up or down depending on traffic.

Which pattern is common in serverless apps?

A Event-driven functions triggered by cloud events

B Running a fixed number of servers 24/7

C Manual database backups

D Using physical hardware only

Serverless apps often use event-driven functions that run only when triggered.

Why can serverless reduce costs?

A You pay for all servers all the time

B You pay only when your code runs

C You must buy hardware upfront

D Costs are fixed regardless of usage

Serverless billing charges only for actual compute time, saving money on idle resources.

What is NOT a benefit of serverless patterns?

A Manual server patching required

B Automatic scaling

C Cost efficiency for variable workloads

D Focus on code, not infrastructure

Serverless removes the need for manual server maintenance like patching.

Explain why serverless patterns matter for building cloud applications.

Think about how serverless changes what developers need to do and how apps respond to demand.

Describe a real-life example where serverless patterns improve an app's performance and cost.

Imagine a photo-sharing app that processes images only when users upload them.
