Basic Two-Tier AWS Architecture

This provides a template for running a simple two-tier architecture on Amazon Web services. The premise is that you have stateless app servers running behind an ELB serving traffic.

To simplify the example, this intentionally ignores deploying and getting your application onto the servers. However, you could do so either via provisioners and a configuration management tool, or by pre-baking configured AMIs with Packer.

After you run terraform apply on this configuration, it will automatically output the DNS address of the ELB. After your instance registers, this should respond with the default nginx web page.

To run, set the environment variables as below with correct values

export AWS_ACCESS_KEY_ID="..." export AWS_SECRET_ACCESS_KEY="..." export AWS_DEFAULT_REGION="..."

Alternatively, you can configure the provider configuration where you invoke the module.

For example, you can use section similar to below.

Specify the provider and access details

provider "aws" { region = "${var.aws_region}" access_key = "${var.access_key}" secret_key = "${var.secret_key}" }

Running the example

run terraform apply -var 'key_name={your_aws_Key_name}' -var 'key_path={location_of_your_key_in_your_local_machine}'

example

terraform apply -var 'key_name=terraform' -var 'key_path=/Users/jsmith/.ssh/terraform.pem
