Web application infrastructure using various AWS Services - Infra Implementation
Project Overview: In our current organization, we've successfully implemented a web application infrastructure using various AWS components. This architecture is designed for scalability, security, and high availability.
1. Virtual Private Cloud (VPC): We established a Virtual Private Cloud (VPC), creating a private network environment that mirrors a traditional data center.
2. Availability Zones (AZ): To ensure fault tolerance and disaster recovery, we set up two Availability Zones (AZ).
3. Public Subnets with NAT Gateways: In each Availability Zone, we configured a Public Subnet with a NAT Gateway. This setup allows internal applications to access the internet securely.
4. Elastic Load Balancer (ELB): We integrated Elastic Load Balancers (ELBs) to distribute incoming traffic among EC2 web servers running Linux, which are hosted in the Web Subnet. This load balancing ensures high availability and efficient resource utilization.
5. Application Servers (App Subnet): Inside the App Subnet, we deployed EC2 instances for our application servers. These servers are responsible for handling application logic. They are also connected to the ELB to evenly distribute traffic.
6. Amazon EFS Shared Storage: For consistent data access, our application servers connect to Amazon Elastic File System (EFS), a shared storage solution that's highly scalable.
7. Database Subnets with Amazon RDS: In separate Database Subnets, we set up Amazon RDS (Relational Database Service) instances, including both primary and secondary databases. This setup ensures data redundancy and availability.
8. Amazon ElasticCache Service: Both primary and secondary databases are connected to Amazon ElasticCache Service, which offers caching to optimize database performance.
9. Web Server Data Storage: Our web servers, which reside in the Web Subnet, are connected to Amazon S3 for storing static files and serving as a backup solution.
10. External Components:
AWS WAF (Web Application Firewall): To enhance security, we implemented AWS WAF, which protects our application from various web-based attacks.
Amazon Route 53 (DNS Service): We use Amazon Route 53 for efficient DNS management and routing traffic to the appropriate services.
AWS Shield (DDoS Protection): For protection against Distributed Denial of Service (DDoS) attacks, we've implemented AWS Shield, providing an additional layer of security.
Conclusion: Our project in the organization demonstrates a robust and scalable AWS infrastructure for our web application. It leverages VPC, multiple AZs, subnets, ELBs, Amazon RDS, ElasticCache, S3, AWS WAF, Route 53, and AWS Shield to provide high availability, security, and efficient data storage and retrieval. This architecture ensures a seamless user experience and data protection, making it a critical asset for our organization.
