Backend

The backend is deployed on AWS using Infrastructure as Code (IaC). It leverages Amazon OpenSearch Service for storing job data, Amazon API Gateway for request routing, and AWS Lambda to handle the core application logic.

Beware the costs:
When using AWS, be mindful of service costs, as resources like Amazon OpenSearch Service can become expensive quickly. While AWS Lambda and Amazon API Gateway are generally cost-effective, costs can rise with high traffic. Always monitor usage, set budget alerts, and choose the appropriate AWS region to optimize expenses. For more details, visit AWS Pricing.

1. Create an AWS Account

Before setting up the AWS CLI, you need an AWS account. If you don’t have one, follow these steps:

1. Go to AWS Sign Up and create an account.
2. Provide your email, password, and account details.
3. Enter your billing information (a valid credit card is required).
4. Verify your phone number via OTP.
5. Choose a support plan (Free Tier is recommended for testing).
6. Complete the registration and log in to the AWS Management Console.

2. Configure the AWS CLI

Once your AWS account is set up, install and configure the AWS CLI.

Install AWS CLI

Follow the official guide to install the AWS CLI:
🔗 AWS CLI Installation

Set Up AWS CLI

Run the following command:

aws configure

You will be prompted to enter:

• AWS Access Key ID
• AWS Secret Access Key
• Default AWS Region (e.g., us-east-1)
• Output format (default: json)

To verify the setup, run:

aws sts get-caller-identity

This should return details about your AWS account, confirming successful configuration.

Steps to deploy the backend

• Run make build-layers to install python deps in the lambda layer
• Run sam build --template-file templates/functions_template.yaml to build the lambda functions and the layers
• Run sam deploy --template-file templates/functions_template.yaml to actually deploy on AWS
