configured.<\/li>\n\n\n\n<li>Basic understanding of AWS services (EC2, RDS, etc.).<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Step 1: Creating a VPC and Subnets<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Define a VPC and create public and private subnets.<\/li>\n\n\n\n<li>Set up Internet Gateway and NAT Gateway for internet access.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Step 2: Setting Up Security Groups<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Create security groups for the web, application, and database layers.<\/li>\n\n\n\n<li>Configure rules to allow traffic between these layers and restrict external access.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Step 3: Deploying the Presentation Layer<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use Terraform to deploy an EC2 instance for the web server (Nginx\/Apache).<\/li>\n\n\n\n<li>Optionally, configure an Elastic Load Balancer (ELB) for high availability.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Step 4: Deploying the Application Layer<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Set up EC2 instances for the application servers.<\/li>\n\n\n\n<li>Deploy the application code to these instances, connecting them to the web layer.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Step 5: Deploying the Database Layer<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use Terraform to create an RDS instance in the private subnet.<\/li>\n\n\n\n<li>Configure the database connection parameters for the application

communicate with the application layer and the application layer with the database.<\/li>\n\n\n\n<li>Test connectivity and application functionality.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Best Practices<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use Terraform modules to manage each layer separately.<\/li>\n\n\n\n<li>Implement state management using Terraform Cloud or an S3 bucket with DynamoDB for state locking.<\/li>\n\n\n\n<li>Automate the deployment using CI\/CD pipelines.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Challenges and
