Serverless AWS Cost Optimization

This GitHub repository showcases the powerful trio of Terraform, AWS Lambda, and Event Bridge for achieving cost optimization in your AWS infrastructure. With a focus on automation and intelligent strategies, you can effectively reduce AWS expenditure without compromising performance or functionality.

🔑 Key Features

• Infrastructure as Code: Define your AWS infrastructure in a declarative manner using Terraform configurations, enabling easy versioning, management, and environment reproducibility.

• Lambda Functions: Explore the creation of serverless functions using AWS Lambda to perform specific tasks in response to events. Examples include processing incoming data or triggering automated actions.

• Event Bridge: Learn how to leverage AWS Event Bridge to establish event-driven architectures, enabling decoupled communication between different services. This facilitates efficient cost optimization through event filtering and routing.

• Cost Optimization Techniques: Discover various techniques for AWS cost optimization, including intelligent resource scaling, serverless architecture design patterns, efficient event routing, and usage-based cost analysis.

• Sample Workflows: Find practical examples of cost optimization workflows that combine Terraform, Lambda functions, and Event Bridge rules. These workflows automate common tasks, minimize resource usage, and reduce unnecessary costs.

⚡️ Prerequisites

• You must have an AWS account and configure your CLI profile.
• Terraform must be installed. Learn how to install Terraform

• Please first completed part one you will need the EC2 instance ID's i-xxxxxxxxxxxxx from the output provided after this deployment is done. You can also copy them from the console once is completed Part one EC2 Creation

⚠️ Cautions

• As an AWS best practice, grant this code least privilege, providing only the necessary permissions to perform a task. For more information, see Grant Least Privilege in the AWS Identity and Access Management User Guide.
• This code has been tested in the us-east-1 AWS Region only. However, it should work in any other region.
• Running this code may result in charges to your AWS account.

▶️ How to Run This Code

🚀 Quick Start

cd serverless_AWS_cost_optimization
terraform init
terraform validate
terraform plan
terraform apply --auto-approve

💥 Quick Destroy

terraform destroy --auto-approve

📌 Notes

- clone this Git repo
- cd to the the directory serverless_AWS_cost_optimization
- copy __EC2_ID's__ from previous deployment and paste them each on __start.py__ and __stop.py__ place holders
- use terraform __init__ command to initialize the Terraform working directory and to download plugins for a provider (aws)
- terraform validate command will validate the code before actual deployment
- terraform plan command will show the execution code before making the actual deployment
- terraform apply
- Alternate command : terraform apply -auto-approve
- terraform destroy
- Alternate command : terraform destroy -auto-approve
- terraform fmt -recursive # A way to format the terraform code
