AWS-powered web application directory, designed for high availability and resilience.
The application is architected for high availability insode a VPC across multiple Availability Zones (AZs) in the US East (N. Virginia us-east-1) and US East (Ohio us-east-2) regions for replication, secure using Firewall SecurityGroups, NAT Gateway ensuring reliable and consistent access using the services below:
- Virtual Private Cloud (VPC): Configured with 6 subnets spanning 2 different AZs for redundancy and fault tolerance.
- Subnets:
- Public Subnet: Provides access to the Internet for the EC2 instances.
- Private Subnet (EC2): Hosts the web application instances, isolated for security.
- Private Subnet (Database): Reserved for future database implementations, currently not in use due to DynamoDB's managed service.
- DynamoDB: Serves as the scalable and managed NoSQL database solution.
- Amazon S3: Utilized for storing and retrieving application images, integrated with DynamoDB.
- Security Groups: Configures firewall rules to control traffic to EC2 instances.
- Target Groups: Directs traffic to appropriate EC2 instances via the Application Load Balancer.
- Application Load Balancer (ALB): Distributes incoming application traffic across multiple targets, such as EC2 instances, in multiple Availability Zones.
- Auto Scaling Groups: Automatically adjusts the number of EC2 instances in response to traffic demands.
The project incorporates other AWS services to enhance functionality, including IAM Roles for security best practices, launch templates, NAT Gateway and more.
