Problem Statement and Solution

Problem Statement: Modern applications demand a robust and flexible architecture that can handle varying workloads while maintaining security and high availability. Deploying such an infrastructure manually can be complex, error-prone, and time-consuming. The need for automated infrastructure provisioning is evident as organizations strive to ensure efficient resource utilization and minimize downtime during traffic surges.

Solution: Our solution addresses these challenges head-on by harnessing the power of Terraform, an infrastructure-as-code tool. With this repository, you'll embark on a journey to craft a 3-Tier Architecture—comprising Web, App, and DB layers—on AWS. Each step is meticulously documented, enabling you to effortlessly recreate the entire infrastructure with a single command. Here's a glimpse of the magic you'll experience:

1. VPC Creation and 3-Tier Architecture: Craft a Virtual Private Cloud (VPC) with the essential tiers—Web, App, and DB—laying the foundation for your application's scalability and security.

2. Security Group Sorcery: Watch as AWS Security Groups weave a protective barrier around your architecture, safeguarding your Private EC2 Instances, Bastion Host, and Application Load Balancer.

3. Private EC2 Instances: Journey into the private realms of your VPC to summon two Private EC2 Instances, handling the core processing tasks of your application.

4. Bastion Host and NAT Gateway: Create a fortified entry point into your architecture with a Bastion Host, complete with a dedicated Elastic IP and a NAT Gateway for secure communication.

5. Application Load Balancing Act: Witness the orchestration of an Application Load Balancer, seamlessly distributing incoming traffic among your Private EC2 Instances for impeccable performance.

6. Auto Scaling Symphony: Craft a Launch Template and orchestrate an Auto Scaling Group that adapts to traffic fluctuations, ensuring optimal resource utilization and high availability.

7. Scaling Intelligence: Employ Target Tracking Scaling Policies to dynamically adjust your infrastructure's capacity, intelligently responding to performance metrics.

8. Time-Bound Scaling: With Scheduled Actions, learn how to predictively scale your infrastructure to meet anticipated traffic patterns efficiently.

9. Notifying the Oracle: Create an SNS Topic for notifications, allowing your architecture to communicate its state and events to the outside world.

Get Started: Ready to wield the power of Terraform and transform your AWS infrastructure deployment? Simply clone this repository and follow the detailed guide provided. Each module, resource, and configuration file has been meticulously organized to streamline your learning experience. With hands-on practice, you'll become a master of infrastructure deployment, enabling your applications to thrive in the cloud.
