Environment Management Platform for Automated Configuration and Lifecycle Management of E-Commerce Order Management Applications

Description

This project is about automating the creation, configuration, management, and lifecycle of different application environments for a containerized E-Commerce Order Management Application. The platform provides standardized Development, Testing, Staging, and Production environments and ensures that application configurations remain consistent across them. It reduces manual environment setup, prevents configuration differences, and supports controlled promotion of applications from one environment to another.

Aim

To design and implement an Environment Management Platform using Kubernetes, Docker, Git, and GitOps to automate environment provisioning, configuration management, application promotion, and lifecycle operations for E-Commerce Order Management Applications.

Objectives

01 Automate application environment creation and configuration.
02 Provide standardized Development, Testing, Staging, and Production environments.
03 Maintain consistent configurations across environments.
04 Manage configurations using version-controlled Git repositories.
05 Automate application promotion between environments.
06 Reduce manual setup and configuration work.
07 Support configuration rollback when required.
08 Isolate different application environments.
09 Simplify environment lifecycle management.

Application Workflow

01

Stage 1. User Login & Authentication

Process

The customer or authorized user logs into the E-Commerce Order Management Application using their registered credentials.

Tools
Keycloak Kubernetes
Implementation

The application sends the login request to Keycloak. Keycloak validates the user's identity and provides access to the appropriate application functions.

02

Stage 2. Product Search & Selection

Process

The customer searches for products, views product information, and selects the required products.

Tools
PostgreSQL Kubernetes
Implementation

The application retrieves product information from PostgreSQL and displays the available products to the customer. The application services run as Docker containers inside Kubernetes.

03

Stage 3. Cart & Order Creation

Process

The customer adds products to the shopping cart and places an order.

Tools
PostgreSQL Kubernetes
Implementation

The application records the selected products, quantities, customer information, and order details in PostgreSQL and creates the order with the appropriate status.

04

Stage 4. Order Processing

Process

The application processes the customer order and updates the order status.

Tools
Python PostgreSQL Kubernetes
Implementation

Application services validate the order, calculate the required values, process the order information, and update the order status in PostgreSQL.

05

Stage 5. Payment & Order Confirmation

Process

The customer completes the payment and the application confirms the order.

Tools
PostgreSQL Kubernetes
Implementation

The application sends the payment request to the payment service, receives the payment result, and updates the order status as Paid, Pending, or Failed in PostgreSQL.

06

Stage 6. Order Fulfillment & Status Tracking

Process

The order is prepared for delivery and the customer tracks the current order status.

Tools
PostgreSQL Kubernetes
Implementation

The application updates order statuses such as Confirmed, Processing, Shipped, Delivered, or Cancelled and stores the status changes in PostgreSQL.

07

Stage 7. Order Completion & Logout

Process

The customer reviews the completed order and logs out of the application.

Tools
PostgreSQL Keycloak Kubernetes
Implementation

The application retrieves the final order information from PostgreSQL and displays the order status. After completing the activities, the user logs out and the application session is terminated through Keycloak.

Cloud Infrastructure and Tools

Container Orchestration Platform Kubernetes

Runs and manages the E-Commerce Order Management Application across separate Development, Testing, Staging, and Production namespaces.

Container Platform Docker

Packages the E-Commerce Order Management Application and its dependencies into containers so the same application image can run consistently across different environments.

Configuration & Version Control Git

Stores application and environment configurations in version-controlled repositories and maintains a history of configuration changes.

GitOps Configuration Management ArgoCD

Synchronizes approved configurations stored in Git with the appropriate Kubernetes environments and supports controlled application promotion and rollback.

Database PostgreSQL

Stores customer information, product information, cart data, order details, payment status, and order tracking information.

Identity & Access Management Keycloak

Provides authentication and role-based access for customers and authorized application users.

Target Compute Infrastructure Cloud EC2 Instances

Provides the virtual servers used to run the self-hosted Kubernetes cluster and application environments.

Server Operating System Ubuntu Server 24.04 LTS

Provides the Linux operating system for the EC2 servers hosting Kubernetes.

Cloud Networking Cloud VPC

Provides the private cloud network for the Kubernetes infrastructure and separates public and private application traffic.

Security Controls Cloud Security Groups + Network ACLs

Control network access and protect the Kubernetes servers and application environments from unauthorized traffic.

Cloud Storage Cloud EBS

Provides persistent block storage for EC2 servers and Kubernetes workloads that require persistent data.

Implementation Process

01
Step 1 – Analyze Application and Environment Requirements
  • Review the E-Commerce Order Management Application architecture, services, dependencies, and resource requirements.
  • Identify the required Development, Testing, Staging, and Production environments.
  • Define common and environment-specific configuration requirements.
  • Define networking, security, storage, CPU, and memory requirements.
  • Define application promotion and environment lifecycle requirements.
02
Step 2 – Create the Cloud Infrastructure
  • Create the Cloud VPC and required public and private subnets.
  • Create cloud EC2 instances using Ubuntu Server 24.04 LTS.
  • Configure cloud Security Groups and Network ACLs.
  • Attach cloud EBS storage where persistent storage is required.
  • Configure the self-hosted Kubernetes infrastructure on the EC2 servers.
03
Step 3 – Configure Kubernetes Environments
  • Create separate Kubernetes namespaces for Development, Testing, Staging, and Production.
  • Deploy the E-Commerce Order Management Application using Docker containers.
  • Configure environment-specific application settings and resource limits.
  • Configure Kubernetes Services, networking, health checks, and persistent storage.
  • Verify that each environment operates independently.
04
Step 4 – Automate Configuration and Deployment
  • Store environment configurations in a controlled Git repository.
  • Configure ArgoCD to synchronize approved Git configurations with Kubernetes.
  • Automate application configuration updates across the required environments.
  • Define controlled promotion from Development to Testing, Staging, and Production.
  • Test configuration updates and rollback procedures.
05
Step 5 – Testing and Production Operation
  • Test the application in the Development environment.
  • Promote the approved configuration through Testing and Staging.
  • Verify that environment-specific configurations are applied correctly.
  • Promote the validated application configuration to Production.
  • Continuously manage environment configurations, updates, rollback, and lifecycle operations.

Proposed Solution

The proposed solution provides a centralized Environment Management Platform that automates the creation, configuration, deployment, and lifecycle management of Development, Testing, Staging, and Production environments for E-Commerce Order Management Applications. Kubernetes manages the application environments, Docker provides consistent application containers, Git maintains version-controlled configurations, and ArgoCD synchronizes approved configurations from Git to Kubernetes. The platform runs on cloud EC2 with Ubuntu Server 24.04 LTS inside an cloud VPC, with cloud security groups and Network ACLs providing network security and cloud EBS providing persistent storage.
