🚨 Prerequisites 🚨

Before you get started, make sure you have the following prerequisites in place:

🟢Terraform installed.

🟢AWS IAM credentials configured.

🟢Git for cloning the repository.

☁️ Web Tier ☁️

The Web Tier is the entry point for incoming user requests. It typically includes:

⚫Load Balancer: Distributes traffic across multiple web servers.

⚫Auto Scaling: Automatically adjusts the number of web servers based on traffic.

⚫Security Groups: Controls incoming and outgoing traffic to the web servers.

🚀 Application Tier 🚀

The Application Tier hosts the application servers responsible for running business logic and interacting with the database tier. Key components include:

⚫Application Servers: These run your application code and can be horizontally scaled.

⚫Load Balancer: Distributes traffic to the application servers.

⚫Auto Scaling: Automatically adjusts the number of web servers based on traffic.

⚫Security Groups: Controls incoming and outgoing traffic to the application servers.

💾 Database Tier 💾

The Database Tier stores and manages our application data. We use Amazon RDS for a managed database service. Key components include:

⚫Amazon RDS: A managed database service for MySQL/PostgreSQL/SQL Server databases.

⚫Security Groups: Control incoming and outgoing traffic to the database.

🔧 Terraform Configuration 🔧

The Terraform configuration for this project is organized into different resources to create the necessary AWS infrastructure components. Key resources include:

⚫Virtual Private Cloud (VPC)

⚫Subnets and Route Tables

⚫Security Groups and Network ACLs

⚫Load Balancers

⚫Auto Scaling Groups

⚫RDS Database Instances

🚀 Deployment 🚀

Follow these steps to deploy the architecture:

⚫Clone the repository

⚫Make changes as per your needs.

⚫Initialize Terraform and apply the configuration:

⚫terraform init

⚫Review the changes and confirm.

💼 Usage 💼

Scaling

⚫To scale the Web or Application Tier, use Auto Scaling configurations provided in the respective Terraform files. Adjust the desired capacity to match your scaling requirements.

Database Management

⚫Access the Amazon RDS instance in the Database Tier to manage your data.

Load Balancing

⚫Configure the load balancer in the Web and Application Tiers to distribute traffic evenly.

Security Considerations

⚫Review and customize the security groups and network ACLs to meet your specific security requirements.
