Overview

You will deploy a highly available, scalable, and secure microservices application across multiple AWS regions. The solution leverages advanced tools and practices to simulate a real-world production environment. Key components include infrastructure provisioning, container orchestration, continuous deployment, automated incident response, and robust security monitoring.

Objectives

In this challenge lab, you will:

• Provision Multi-Region Infrastructure: Use Terraform to deploy resources across two AWS regions, including VPCs, subnets, EC2 instances, auto-scaling groups, and global load balancers.
• Implement Container Orchestration: Deploy microservices using Docker and Kubernetes (EKS) with multi-tenancy support.
• Automate Server Configuration: Use Ansible to configure instances, deploy monitoring agents, and harden security settings.
• Set Up Advanced CI/CD Pipelines: Build and deploy Docker images via GitHub Actions with Blue/Green and canary release strategies.
• Integrate Real-Time Monitoring and Incident Response: Configure AWS CloudWatch, CloudTrail, and custom Lambda functions to automate incident detection and remediation.
• Enhance Security Posture: Utilize AWS IAM for fine-grained access control, AWS WAF for application protection, and AWS KMS for data encryption.

What You Will Learn

This lab covers high-impact, advanced practices used in today’s production environments:

• Infrastructure as Code (IaC): Advanced Terraform modules and multi-region state management.
• Containerization & Orchestration: Deep dive into Docker and Kubernetes (EKS) for managing microservices.
• Configuration Management: Using Ansible to ensure secure, repeatable server configurations.
• Continuous Integration/Deployment: Advanced GitHub Actions workflows with automated testing, Blue/Green, and canary deployments.
• Global Traffic Management: Implementing AWS Global Accelerator or Route 53 for multi-region load balancing.
• Real-Time Observability & Automation: Leveraging CloudWatch, CloudTrail, and Lambda for proactive incident response.
• Security Best Practices: Enforcing least privilege access, WAF rules, and encryption for sensitive data.

Project Architecture

Components

Following are the key components of the project:

Microservices Application

A multi-tenant web application composed of various interdependent services (e.g., user authentication, data processing, API gateway).

Infrastructure

• Multi-Region VPCs & Subnets: Isolated networking across two AWS regions.
• EC2 & EKS Clusters: Compute resources for running microservices and container orchestration.
• Global Load Balancing: AWS Global Accelerator or Route 53 configured for cross-region traffic management.
• ECR: A centralized repository for Docker images.
• Auto Scaling & Self-Healing: Auto-scaling groups and Kubernetes health checks ensure resiliency.

Deployment Pipeline

• GitHub Actions: Automated CI/CD pipelines triggering builds, tests, and deployment workflows.
• Blue/Green & Canary Deployments: Gradual rollout strategies to minimize risk during updates.

Monitoring & Security

• CloudWatch & CloudTrail: Continuous monitoring of logs, metrics, and API activity.
• AWS WAF & KMS: Application firewall and encryption services to secure data and services.
• Custom Lambda Functions: Automated remediation for critical incidents.

Steps Involved

1. Multi-Region Infrastructure Provisioning with Terraform:

   • Develop Terraform modules for VPC, EC2, EKS, auto-scaling, and global load balancing.
   • Manage remote state and ensure cross-region consistency.

2. Server and Cluster Configuration with Ansible:

   • Automate installation of Docker, security agents, and monitoring tools on EC2 instances.
   • Configure EKS worker nodes with security hardening and compliance settings.

3. CI/CD Pipeline Setup with GitHub Actions:

   • Create workflows for building Docker images, running integration tests, and deploying to ECR and EKS.
   • Integrate Blue/Green and canary deployment strategies to manage service updates.

4. Microservices Deployment and Orchestration on EKS:

   • Define Kubernetes manifests or Helm charts for deploying services.
   • Configure service discovery, load balancing, and health checks for each microservice.

5. Global Traffic Management:

   • Set up AWS Global Accelerator or Route 53 to route traffic across regions based on latency and health.
   • Ensure seamless failover and minimal downtime.

6. Monitoring, Logging, and Automated Incident Response:

   • Configure CloudWatch dashboards, alarms, and log groups for real-time observability.
   • Implement CloudTrail for audit logging.
   • Deploy Lambda functions for automated incident remediation based on predefined triggers.

7. Advanced Security Configuration:

   • Create detailed IAM policies with least privilege for all components.
   • Set up AWS WAF rules to protect against common web exploits.
   • Use AWS KMS to manage encryption keys for data at rest and in transit.

Expected Outcomes

Upon completion, you will have:

• A fully automated, multi-region AWS deployment of a microservices application.
• Hands-on experience with advanced IaC, container orchestration, and CI/CD techniques.
