Deploy a Modular and Scalable Virtual Network Architecture with Amazon VPC.
Pre-Requisites include having an AWS account with necessary permissions and preparing the web application repository.
Create a Golden AMI by launching an EC2 instance with Ubuntu 24.0 and installing necessary dependencies like Apache Web server, Git, CloudWatch Agent, and AWS SSM Agent.
To configure CloudWatch Agent, save the memory_metrics.json file at /opt/aws/amazon-cloudwatch-agent/bin/ directory.
Create an AMI from the EC2 instance, test it by launching a new EC2 instance, and verify connectivity using SSH.
Create IAM roles for SSM and CloudWatch functionalities, set permissions for S3 bucket, and create a VPC network with multiple subnets.
Configure Internet Gateways, NAT Gateways, Route Tables, and Transit Gateway for effective traffic routing between VPCs.
Set up VPC Flow Logs, Security Groups, Target Groups, Network Load Balancer, and Auto Scaling Group for optimal performance.
Update Route53 hosted zone for DNS routing, and validate by logging into private instances via the Bastion Host.
By following these steps, one can deploy a scalable VPC architecture on the AWS cloud efficiently.
