Data Science Model Deployments and Cloud Computing on GCP - Lab - Scalability and Instance Types in App Engine

The video tutorial covers the importance of scalability in applications, particularly in cloud environments like Google App Engine. It explains the need to control scalability to manage costs effectively. The tutorial details the features of Google App Engine, including automatic and manual scaling, and how to configure these using YAML files. It also discusses key parameters for automatic scaling, such as CPU utilization and latency, and provides practical tips for deploying applications with these scaling features.

Why is it important to control the scalability of an application?

• To reduce development time

• To enhance user experience

• To improve application performance

• To manage costs effectively

What are the two types of scalability features available in Google App Engine?

• Cloud and On-premise

• Dynamic and Static

• Automatic and Manual

• Horizontal and Vertical

Which instance type is used by default if no parameters are specified in the YAML file?

• B1

• F1

• B8

• F4

In manual scaling, what does the 'instances' parameter specify?

• The amount of memory per instance

• The storage size per instance

• The number of instances to spin up

• The number of CPUs per instance

What happens when the CPU utilization of an instance reaches 80% in automatic scaling?

• The application is restarted

• The instance is upgraded

• A new instance is spun up

• The instance is shut down

What does 'max idle instances' parameter control in automatic scaling?

• The maximum number of instances that can be idle

• The maximum CPU usage per instance

• The maximum storage per instance

• The maximum memory usage per instance

What is the significance of 'max concurrent requests' in automatic scaling?

• It limits the number of requests per application

• It defines the number of requests per instance before scaling

• It determines the number of requests per minute

• It sets the maximum number of users

What additional resources can be specified in automatic scaling?

• User sessions

• Network bandwidth

• Virtual cores, memory, and storage

• Database connections

Why is it important to understand the pricing of instance types?

• To enhance security

• To avoid unexpected costs

• To improve user satisfaction

• To ensure high performance

Which instance types are considered the lowest in pricing?

• F8 and B8

• F2 and B2

• F4 and B4

• F1 and B1
