To create an improved network diagram using draw.io$,$ I'll provide a detailed description of how to structure it based on the given requirements. The key components you need to include are:

Explanation:

VPC

Public and Private Subnets

Internet Gateway

NAT Gateway or NAT Instance

Elastic Load Balancer

Auto Scaling Group

Application Servers

RDS Databases

Security Groups

Network ACLs

Step $2$

Here$$s how to design the architecture:

Explanation:

VPC:

Create a VPC to enclose all resources.

Subnets:

Public Subnet $($Contains the Load Balancer, NAT Gateway$/$Instance$)$

Private Subnet $($Contains the Application Servers and RDS Databases$)$

Internet Gateway:

Attach an Internet Gateway to the VPC$.$

NAT Gateway$/$Instance:

Place the NAT Gateway$/$Instance in the Public Subnet.

Elastic Load Balancer $($ELB$)$:

Place the ELB in the Public Subnet.

Auto Scaling Group:

Configure an Auto Scaling Group behind the ELB to manage Application Server instances in the Private Subnet.

Application Servers:

Deploy Application Servers in the Private Subnet, managed by the Auto Scaling Group.

RDS Databases:

Deploy a master RDS instance in one Availability Zone$$s Private Subnet.

Deploy a standby RDS instance in another Availability Zone$$s Private Subnet.

Security Groups:

Create Security Groups to control access to the ELB, Application Servers, and RDS instances.

Network ACLs:

Apply Network ACLs to the subnets for additional security.

Step$-$by$-$Step Drawing on draw.io

Create the Main VPC Container:

Use a rectangle to represent the VPC$.$ Label it $"$VPC$".$

Add Subnets:

Draw two rectangles inside the VPC for the Public Subnet and Private Subnet. Label them accordingly.

Internet Gateway:

Place an icon or shape for the Internet Gateway on the edge of the VPC$.$

NAT Gateway$/$Instance:

Place an icon for the NAT Gateway$/$Instance inside the Public Subnet.

Elastic Load Balancer:

Place an ELB icon inside the Public Subnet.

Auto Scaling Group:

Inside the Private Subnet, indicate the Auto Scaling Group with multiple server icons or a scalable group icon.

Application Servers:

Within the Auto Scaling Group, add icons for Application Servers.

RDS Databases:

Add RDS icons in the Private Subnet, with one master instance in one AZ and a standby instance in another AZ$.$

Security Groups:

Draw circles or use icons to represent Security Groups around the ELB, Application Servers, and RDS instances.

Network ACLs:

Indicate Network ACLs at the subnet boundaries.

Connections and Arrows:

Draw arrows to represent the flow of traffic:

From the Internet to the Internet Gateway.

From the Internet Gateway to the ELB.

From the ELB to the Application Servers.

From the Application Servers to the RDS instances.

From the NAT Gateway$/$Instance to the Application Servers for outbound internet access.

You can use the provided bootstrap script to configure your servers:

#$!/$bin$/$bash

yum update $-$y

yum install httpd $-$y

service httpd start

chkconfig httpd on

cd $/$var$/$www$/$html

echo "Hello World from Server $01">$ index.html
