Design for Performance and Scalability AWS Architecture

---

This projects have the following objectives:

• Design AWS Architecture for Performance and Scalability
• Plan a Serverless architecture
• Estimate infrastructure costs and setup cost monitoring
• Use Terraform to provision the AWS architecture

AWS Architecture Schematics

Plan and provision a cost-effective AWS infrastructure for a new social media application development project for 50,000 single-region users. The project requires the following AWS infrastructure and services.

provision a cost-effective AWS infrastructure for a new social media application

Project Instructions

Exercise 1

1. Download the starter code.
2. In the main.tf file write the code to provision
   • AWS as the cloud provider
   • Use an existing VPC ID
   • Use an existing public subnet
   • 4 AWS t2.micro EC2 instances named Udacity T2
   • 2 m4.large EC2 instances named Udacity M4
3. Run Terraform.
4. Take a screenshot of the 6 EC2 instances in the AWS console and save it as Terraform_1_1.
5. Use Terraform to delete the 2 m4.large instances

Destroy a specific resource:

terraform destroy -target RESOURCE_TYPE.NAME

terraform destroy -target aws_instance.Udacity_M4

6. Take an updated screenshot of the AWS console showing only the 4 t2.micro instances and save it as Terraform_1_2

Exercise 2

1. In the Exercise_2 folder, write the code to deploy an AWS Lambda Function using Terraform. Your code should include:

   • A lambda.py file
   • A main.tf file with AWS as the provider, and IAM role for Lambda, a VPC, and a public subnet
   • An outputs.tf file
   • A variables.tf file with an AWS region

2. Take a screenshot of the EC2 instances page

3. Take a screenshot of the VPC page
