Dynamic Website Hosting on AWS
This project showcases the deployment and hosting of a dynamic website on AWS, integrating various services and components to ensure top-notch performance, scalability, security, and fault tolerance.
Architecture Overview
The website operates on EC2 instances within a Virtual Private Cloud (VPC) configured with both public and private subnets across two Availability Zones. The infrastructure harnesses several key AWS resources:
Virtual Private Cloud (VPC): Offers a segregated portion of the AWS cloud for launching resources.
Internet Gateway: Facilitates communication between VPC instances and the internet.
Security Groups: Function as virtual firewalls, regulating inbound and outbound traffic.
Availability Zones: Utilized to enhance reliability and fault tolerance.
Public Subnets: Host essential infrastructure components like the NAT Gateway and Application Load Balancer.
Private Subnets: House the web servers (EC2 instances) for heightened security.
NAT Gateway: Grants instances in private subnets internet access.
EC2 Instance Connect Endpoint: Enables secure connections to EC2 instances within both public and private subnets.
Application Load Balancer: Distributes incoming web traffic among multiple EC2 instances within an Auto Scaling group.
Auto Scaling Group: Dynamically manages the EC2 instances hosting the website, ensuring availability, scalability, fault tolerance, and elasticity.
AWS Certificate Manager: Safeguards application communications with SSL/TLS certificates.
Simple Notification Service (SNS): Dispatches notifications regarding activities within the Auto Scaling Group.
Route 53: Delivers DNS services for registering and managing the website's domain name.
S3 Bucket: Houses the application code and assets.
Deployment
The deployment process for this infrastructure is automated via scripts and configuration files stored in a GitHub repository. The repository encompasses the following elements:
Reference Diagram: A graphical representation of the AWS infrastructure and its constituents.
Deployment Scripts: Scripts for provisioning and configuring the requisite AWS resources.
Usage
Clone the GitHub repository to your local machine.
Follow the instructions outlined in the repository's documentation to establish the necessary AWS resources.
Deploy the website code and assets to the designated S3 bucket.
Access the website using the registered domain name.
Implementation Details
I hosted a Dynamic Website on AWS for a DevOps project and utilized the following resources:
Virtual Private Cloud (VPC):
Configured a VPC with both public and private subnets spanning two availability zones.
Internet Gateway:
Deployed an Internet Gateway to enable connectivity between the VPC instances and the wider internet.
Security Groups:
Established Security Groups to serve as a network firewall mechanism.
Availability Zones:
Leveraged two Availability Zones to increase system reliability and fault tolerance.
Public Subnets:
Utilized Public Subnets for infrastructure components like the NAT Gateway and Application Load Balancer.
EC2 Instance Connect Endpoint:
Implemented EC2 Instance Connect Endpoint for secure connections to assets within both public and private subnets.
Private Subnets:
Placed web servers (EC2 instances) within Private Subnets for enhanced security.
NAT Gateway:
Allowed instances in both the private Application and Data subnets to access the Internet via the NAT Gateway.
Website Hosting:
Hosted the website on EC2 Instances.
Application Load Balancer (ALB):
Used an Application Load Balancer and a target group for evenly distributing web traffic to an Auto Scaling Group of EC2 instances across multiple Availability Zones.
Auto Scaling Group (ASG):
Utilized an Auto Scaling Group to automatically manage EC2 instances, ensuring website availability, scalability, fault tolerance, and elasticity.
Certificate Manager (ACM):
Secured application communications using a Certificate Manager.
Simple Notification Service (SNS):
Configured Simple Notification Service (SNS) to alert about activities within the Auto Scaling Group.
Domain Registration and DNS:
Registered the domain name and set up a DNS record using Route 53.
S3 Storage:
Used S3 to store application codes.
