🏦 Bank App Cloud Documentation

Project Overview

Introducing the Infraninjas Bank App project! This initiative focuses on building a robust, secure, and scalable banking application with a solid DevOps pipeline and infrastructure foundation to support ongoing development, deployment, and maintenance.

What We Built

Our Bank App is a modern banking platform designed to deliver seamless, secure banking experiences to our users. It handles everything from account management to transactions and customer data securely and efficiently.

Key Focus Areas

Infrastructure as Code (IaC) with Terraform
- We define and manage our entire infrastructure using Terraform. This means our cloud resources like Virtual Private Clouds (VPCs), subnets, and security groups are created and maintained consistently and reliably.
- Terraform state files are securely stored in an AWS S3 bucket and locked using AWS Dynamodb, ensuring our infrastructure's history and state are safely tracked.
DevOps Pipeline & Continuous Delivery
- Our DevOps pipeline automates the build, test, and deployment processes. This enables rapid, repeatable, and reliable delivery of updates to the Bank App.
- Code is version controlled in GitHub repositories, allowing collaborative development and safe change management.
Backup & Disaster Recovery
- We implement comprehensive backup strategies covering infrastructure, application code, and databases.
- Infrastructure state are locked using Dynamodb to avoid tampering of our infrastucture state.
1. Security & Compliance
  - Security is paramount. We adopt best practices such as endpoint privilege management, access controls, and secure data handling.
  - Our environment segregates development, staging, and production to reduce risk.
  - Audit logs and monitoring tools keep track of system activity for compliance and troubleshooting.
2. Collaboration & Documentation
  - The project documentation covers detailed steps for cloning repositories, pipeline configurations, and infrastructure setups.
  - Team collaboration tools and communication channels are leveraged to maintain alignment and transparency.
Why This Matters

By combining Infrastructure as Code, automated DevOps pipelines, and solid backup strategies, we build a resilient foundation that supports innovation without compromising security or stability. Our goal is to deliver a banking app that users trust and enjoy, while enabling the development team to work efficiently and confidently.

Team Setup

Step 1: Architectural Designs

The architectural design below reflected how we built, deployed, and managed our banking application in the cloud using AWS, Terraform, Kubernetes (EKS), and CI/CD automation. The diagram we used illustrated how core components such as VPCs, subnets, NAT gateways, EKS clusters, load balancers, CI/CD pipelines, and domain services interacted within our AWS environment.

This visual served as a go to reference for team members and stakeholders, helping everyone quickly understand the application’s infrastructure, scalability, and deployment flow.
