AWS Cloud Development Kit - From Beginner to Professional - Highly Available Web Servers with AutoScaling and Applicatio

This video tutorial explains how to set up web servers in an autoscaling group with an application load balancer using AWS CDK. It covers the importance of such architecture for handling increased web traffic and provides a step-by-step guide to building the architecture, configuring the load balancer, and setting up the autoscaling group. The tutorial also includes deployment and testing of the setup, ensuring the web application can handle traffic efficiently.

What is the primary benefit of using an auto-scaling group with a load balancer?

• To automatically adjust the number of servers based on traffic

• To reduce the cost of web servers

• To eliminate the need for a domain name

• To ensure a single point of failure

In the architecture discussed, what is the role of the application load balancer?

• To provide database services

• To manage DNS settings

• To distribute incoming traffic across multiple servers

• To store user data

Which construct is essential for building a load balancer in the CDK stack?

• EC2 construct

• Load balancer construct

• VPC construct

• IAM construct

What is the purpose of configuring security groups for the load balancer?

• To allow traffic on specific ports

• To configure DNS settings

• To increase server storage

• To manage user access

What is a prerequisite for setting up an auto-scaling group?

• Configuring a database

• Setting up a VPC

• Creating a DNS record

• Defining an AMI and bootstrap scripts

Why is it recommended to use the SSMS sessions manager instead of a key name?

• It provides better security

• It is easier to manage servers without a key name

• It is cheaper

• It allows for more server instances

What is the significance of setting the min and max capacity in an auto-scaling group?

• To define the network bandwidth

• To control the number of active servers

• To determine the number of databases

• To set the storage capacity

What is the final step before deploying the stack?

• Synthesizing the stack

• Adding a database

• Creating a backup

• Configuring DNS settings

How can you verify that the web servers are correctly set up behind the load balancer?

• By inspecting the VPC settings

• By checking the server logs

• By accessing the load balancer's DNS name

• By reviewing the IAM roles

What indicates that the traffic is being distributed correctly across the web servers?

• The DNS name is unreachable

• The IP address remains constant

• The server logs show no activity

• The IP address changes upon refresh
