This directory contains CloudFormation templates for deploying various AWS resources.

-   ec2.yaml - Deploys EC2 instances with a load balancer in a VPC setup with proper security groups and networking.

• vpc.yaml - Creates a VPC with public, application, and database subnets in two availability zones, along with associated components like Internet Gateway, Bastion Hosts(used in-place of Internet Gateways), route tables, and security groups.
• rds.yaml - Template for provisioning an RDS database instance.
• asg.yaml - Setup for Auto Scaling Group to manage EC2 instances.
• iam.yaml - IAM roles and policies definitions.
• s3-bucket.yaml - Template for creating an S3 bucket.
• s3-static.yaml - Creates an S3 bucket configured for static website hosting.

To deploy any of these templates, use the AWS CLI:

aws cloudformation create-stack --stack-name <your-stack-name> --template-body file://<template-file-path.yaml>

For templates that require parameters, you can specify them using the --parameters option or create a parameters file.

Example:

aws cloudformation create-stack --stack-name my-vpc-stack --template-body file://vpc.yaml

The templates in this directory follow a multi-tier architecture approach:

• VPC with public and private subnets across multiple availability zones
• Bastion hosts in public subnets for secure SSH access
• Application instances in private subnets
• Database instances in isolated subnets
• Web servers with load balancing for high availability
• S3 buckets for static content and storage
