Infrastructure-as-Code Automation for Multi-Environment Deployment of a Distributed Digital Identity Management Application

Description

This project creates an automated Infrastructure-as-Code (IaC) framework for deploying and managing a distributed Digital Identity Management Application. Instead of manually creating and configuring cloud infrastructure, the required infrastructure is defined and managed as code. When changes are made, the system automatically provisions or updates the infrastructure and maintains consistent Development, Staging, and Production environments for the application.

Aim

To develop an automated Infrastructure-as-Code (IaC) framework for deploying and managing a distributed Digital Identity Management Application consistently across Development, Staging, and Production environments.

Objectives

01 To define the required cloud infrastructure using code.
02 To automate the creation and configuration of application infrastructure.
03 To maintain consistent infrastructure across Development, Staging, and Production environments.
04 To automate infrastructure updates when configuration changes are made.
05 To reduce manual infrastructure configuration and deployment errors.
06 To provide a repeatable and scalable infrastructure deployment process.

Application Workflow

01

Stage 1 – User Registration

Process

A new user creates an account in the Digital Identity Management Application.

Tools
Keycloak PostgreSQL
Implementation

The user provides details such as name, email, phone number, and identity information. Keycloak manages the user identity, while PostgreSQL stores the required user information.

02

Stage 2 – Identity Verification

Process

The application verifies the user's identity.

Tools
Keycloak Python
Implementation

The application validates the submitted identity information and confirms whether the user's identity is valid.

03

Stage 3 – User Login

Process

The registered user logs into the application.

Tools
Keycloak
Implementation

The user enters their credentials. Keycloak authenticates the user and creates an authenticated session.

04

Stage 4 – Single Sign-On (SSO)

Process

The authenticated user accesses multiple connected applications without logging in separately.

Tools
Keycloak OpenID Connect (OIDC)
Implementation

After successful authentication, Keycloak provides an authentication token that allows the user to access authorized connected applications.

05

Stage 5 – Role and Access Management

Process

The application determines which resources and applications the user can access.

Tools
Keycloak
Implementation

The application assigns roles and permissions to users and allows access according to those permissions.

06

Stage 6 – User Profile Management

Process

The user manages their identity and account information.

Tools
Keycloak PostgreSQL
Implementation

The user can update profile information and account settings. The updated information is stored securely.

07

Stage 7 – Access Revocation

Process

The application removes a user's access when it is no longer required.

Tools
Keycloak PostgreSQL
Implementation

When an account is disabled or a user's role changes, Keycloak updates or removes the user's permissions and access to connected applications.

Cloud Infrastructure and Tools

Infrastructure-as-Code Tool OpenTofu

Automatically creates and manages cloud infrastructure such as networks, servers, storage, and security settings using configuration files.

Machine Image Building Tool Packer

Creates pre-configured Ubuntu server images with the required software and dependencies for the Digital Identity Management Application.

Infrastructure Configuration Language HCL (HashiCorp Configuration Language)

Used to define cloud infrastructure resources, variables, and environment-specific configurations for OpenTofu.

Automation Scripting Language Bash

Used to automate server setup, software installation, configuration, and other deployment-related commands.

Compute Resource Cloud EC2

Provides virtual servers to run the Digital Identity Management Application and its supporting services.

Server Operating System Ubuntu Server 24.04 LTS

Provides the stable Linux operating system used on the EC2 servers.

Cloud Networking Resource Cloud VPC

Creates the private cloud network and separates Development, Staging, and Production environments using subnets.

Security Resource Cloud Security Groups + Network ACLs

Control network traffic and protect the application servers and other cloud resources from unauthorized access.

Block Storage Resource Cloud EBS

Provides persistent storage attached to EC2 servers for application data, system files, and logs.

IaC State Storage Resource Cloud S3 + DynamoDB

Cloud S3 stores the OpenTofu state files, while DynamoDB can provide state locking to prevent conflicting infrastructure operations.

Implementation Process

01
Step 1 – Analyze Infrastructure Requirements
  • Identify the infrastructure required for the Digital Identity Management Application.
  • Define Development, Staging, and Production environments.
  • Define required compute, networking, storage, and security resources.
  • Define environment-specific configurations.
02
Step 2 – Create Infrastructure as Code
  • Create OpenTofu configuration files using HCL.
  • Define cloud VPC, subnets, EC2 instances, security groups, and EBS storage.
  • Create reusable configurations for different environments.
  • Configure remote state storage using Cloud S3.
03
Step 3 – Build Server Images
  • Create a Packer configuration for Ubuntu Server.
  • Install the required application dependencies.
  • Configure the server environment.
  • Build a reusable server image for deployment.
04
Step 4 – Automate Infrastructure Provisioning
  • Configure the CI/CD pipeline to execute OpenTofu commands.
  • Validate the infrastructure configuration.
  • Generate an infrastructure plan.
  • Automatically create or update cloud resources.
  • Deploy the infrastructure for Development, Staging, and Production.
05
Step 5 – Deploy and Configure the Application
  • Deploy the Digital Identity Management Application to the provisioned infrastructure.
  • Configure application settings for each environment.
  • Configure networking and security access.
  • Verify that the application services are running correctly.
06
Step 6 – Test and Maintain the Infrastructure
  • Test the Development environment.
  • Validate the Staging environment before production deployment.
  • Verify the Production infrastructure.
  • Test infrastructure updates and rollback procedures.
  • Monitor infrastructure and update the IaC configuration when requirements change.

Proposed Solution

The proposed solution provides an automated Infrastructure-as-Code framework for deploying and managing the Digital Identity Management Application across multiple environments. Instead of manually creating and configuring cloud resources, the system uses OpenTofu to define and manage the infrastructure and Packer to create pre-configured server images. The platform runs on Cloud EC2 with Ubuntu Server 24.04 LTS, inside secure Cloud VPC networks. OpenTofu provisions the required infrastructure from configuration files and maintains consistent Development, Staging, and Production environments. The solution provides automated infrastructure management, consistent environments, faster deployment, reduced configuration errors, and easier infrastructure scaling.

Benefits

Infrastructure Drift Control: OpenTofu can detect differences between the defined infrastructure and the actual cloud infrastructure.
Consistent Environments: The same infrastructure configuration can be reused across Development, Staging, and Production.
Faster Server Setup: Packer creates pre-configured machine images, allowing new servers to be deployed with the required software.
Reduced Configuration Errors: Infrastructure, networking, security, and storage are managed through code instead of manual configuration.
Easy Infrastructure Scaling: New cloud resources can be created quickly by updating the IaC configuration.

Challenges

IaC State Management: OpenTofu state must be managed carefully to avoid conflicts between multiple infrastructure operations.
Configuration Complexity: Managing different settings for Development, Staging, and Production can become difficult.
Infrastructure Errors: Incorrect IaC configurations can create unwanted or unavailable cloud resources.
Security Management: Cloud credentials, access permissions, and infrastructure configurations must be protected.
Learning Curve: Managing OpenTofu, Packer, cloud, and multi-environment infrastructure requires technical knowledge.
