High-Availability AWS VPC Architecture: Managed Services and Multi-AZ

This project delivers a fully managed, highly available AWS VPC architecture designed to ensure scalability, fault tolerance, and secure application delivery. It supports production-grade web applications with multi-AZ deployment, automated provisioning, and secure domain management.

Architecture Overview

Infrastructure as Code & Automation:
The entire setup is provisioned using Terraform, automated via Ansible, with CI/CD pipelines configured in Jenkins and Azure DevOps for repeatable deployments and updates.

Elastic Load Balancer (ELB) & EC2 Deployment:
Traffic is distributed across two EC2 instances deployed in Availability Zones A and B for fault tolerance and high availability.

Reliable Database Layer:
Amazon RDS is configured with cross-AZ replication to ensure database reliability and consistent performance.

Caching & Performance Optimization:
Amazon ElastiCache is integrated to reduce latency and improve application performance.

Private VPC & DNS Management:
Private subnets enhance security, while Route 53 Hosted Zones manage domain routing and DNS resolution.

Key Features & Workflow:

1

Secure and Scalable Web Application Hosting:

– EC2 instances behind ELB ensure load distribution and fault tolerance.
– Auto-scaling policies manage traffic spikes seamlessly.

2

Highly Available Database:

– Amazon RDS with cross-AZ replication ensures zero downtime during maintenance or failures.
– Automated backups and snapshots provide disaster recovery options.

3

Fast Data Access:

– ElastiCache reduces database load and accelerates response times for end-users.

4

Secure Network Architecture:

– Private VPC design isolates resources from public access.
– Security groups and NACLs control inbound/outbound traffic.

5

Automated Infrastructure Management:

– Terraform scripts handle resource provisioning.
– Ansible automates configuration management.
– CI/CD pipelines in Jenkins and Azure DevOps deploy updates reliably.

Summary

Developed a highly available, secure, and automated AWS VPC architecture using ELB, EC2, RDS, ElastiCache, Terraform, and Ansible. Multi-AZ deployment and CI/CD integration ensure production-grade scalability, fault tolerance, and rapid deployment of web applications.
