In today’s fast-paced digital world, ensuring that your application is always available and can handle failures gracefully is crucial. AWS provides robust infrastructure options, and with Terraform, you can manage this infrastructure as code, ensuring consistency, repeatability, and scalability.
In this blog, I’ll walk you through deploying a highly available, fault-tolerant e-commerce web application on AWS using Terraform.
1. Prerequisites
Before we start, ensure you have the following:
AWS Account: You'll need an active AWS account with sufficient permissions.
Terraform Installed: Install Terraform on your local machine. You can download it from the official Terraform website.
AWS CLI: Install and configure the AWS CLI with your credentials.
Basic Knowledge: Familiarity with AWS services (like EC2, RDS, and S3) and Terraform basics.
2. Overview of the Architecture
Key Components:
VPC (Virtual Private Cloud): Isolated network for the application.
Subnets: Public and private subnets across multiple Availability Zones (AZs).
Internet Gateway: To allow access to the public subnet.
NAT Gateway: For outbound traffic from the private subnets.
EC2 Instances: To host the web application.
Auto Scaling Group (ASG): For scaling EC2 instances based on demand.
Elastic Load Balancer (ELB): For distributing traffic across multiple instances.
RDS (Relational Database Service): For a highly available database.
** will update with code soon.**
