KPMG Coding Challenges

This repository contains solutions to the coding challenges presented by KPMG.

Challenge #1: 3-Tier Environment Setup

Approach:

I chose AWS to set up a 3-tier environment. The infrastructure is defined using Infrastructure-as-Code Tool, and the code can be found in the Terraform-3-tier-aws/.

Reproducibility:

To reproduce the environment, follow these steps:

1. Install terraform.
2. Clone this repository.
3. Navigate to the Terraform-3-tier-aws/
4. Execute terraform init , terraform plan , terraform apply to create the 3-tier environment.

Challenge #2: Query Instance Metadata

Language and Implementation:

I used python to write a script s3_bucket_metadata.py that queries the metadata of an instance in AWS s3. The output is formatted as JSON.

Usage:

To use the script:

1. Install python.
2. Execute "python s3_bucket_metadata.py" and provide necessary input.

Bonus Points:

The script allows for retrieving a particular data key individually.

Challenge #3: Nested Object Value Retrieval

Language and Implementation:

I implemented a function in python to retrieve a value from a nested object based on a given key. The code can be found in nested_object.py.

Usage:

To use the function:

1. Import the function into your code.
2. Call the function with the object and key as parameters.

Tests:

To run the tests, execute "python nested_object.py"
