AZ-104: Microsoft Azure Administrator Full Course - App Service Plan Scaling

The video tutorial explains two main options for scaling web applications: scaling up and scaling out. Scaling up involves increasing the computing power of existing virtual machines by upgrading the app service plan, while scaling out involves increasing the number of virtual machine instances. The tutorial also covers autoscaling, which can be configured manually or automatically based on predefined rules and schedules. The video concludes with a summary of the differences between scaling up and scaling out.

What does scaling up primarily involve in the context of web applications?

• Reducing the number of virtual machines

• Decreasing the pricing tier

• Adding more CPU, memory, and disk space

• Increasing the number of virtual machines

How can you increase the number of virtual machine instances for your application?

• By changing the app service plan

• By scaling up

• By scaling out

• By reducing CPU usage

What is the maximum number of instances you can scale out to in an isolated tier?

• 100 instances

• 30 instances

• 50 instances

• 200 instances

Which of the following is a feature of autoscaling?

• Requires no predefined rules

• Based on predefined rules and schedules

• Manual configuration only

• Only available in non-isolated tiers

What is the main difference between scaling up and scaling out?

• Both scaling up and scaling out increase the number of virtual machines

• Both scaling up and scaling out increase computing power

• Scaling up increases computing power, while scaling out increases the number of virtual machines

• Scaling up increases the number of virtual machines, while scaling out increases computing power
