Document Management System

Original Document Management System (Django, JavaScript) rewritten in React / Next.js and deployed on AWS

A large organization is made up of numerous departments. Each department is responsible for storing its own documents, resulting in a large number of documents in the organization. As a result, document management and standardization become more complex, because each department has its own document management process, as well as its own document standard. Document Management System will function as a centralized system, streamlining the document management process.

Objectives

• Streamlining the document management process (create, edit, cancel)
• Maintaining single document standards throughout the organization
• Easing employee document retrieval and management
• Centralizing system for use by all departments in the organization

Technology used

• Development
  • React
    • Next.js
    • NextAuth
    • React Bootstrap
    • next-connect
  • Prisma
  • TypeScript
• Deployment
  • Amazon Web Services
  • Docker
  • Terraform

Cloud Architecture

Overview

• Compute
  • Elastic Container Service (ECS) for hosting the Document Management System
  • Elastic Container Registry (ECR) for storing application's images.
• Database
  • Relational Database Service (RDS) with MySQL 8.0 for storing application's transactional data such as document's metadata, approval process delegation status, etc.
• Storage
  • Simple Storage Services (S3) for storing documents managed by the system.
• Security, Identity and Compliance
  • Cognito as identity and access management for the application.
• Networking
  • Deployed in single region within 2 availability zones
• Load Balance
  • Application Load Balancer (ALB) to distribute loads to each ECS task running in each Availability Zone.
• Developer Tools
  • EC2 as a bastion host to access the resources inside the private subnet using SSH tunneling.
  • S3 for storing Terraform's state used to provision the resources.

Networking Overview

• Virtual Private Cloud (VPC) with 2 subnets in each availability zone (total of 4 subnets
  • Public subnet: Application Load Balancer and NAT Gateway
  • Private subnet: ECS task and RDS database

Application Load Balancer
