AWS Cloud architecture for web hosting

An example of a web hosting architecture on AWS

1. DNS services with Amazon Route 53 – Route 53 is AWS's scalable Domain Name System (DNS) web service. It helps manage domain registration and routing traffic to your web applications. Route 53 can also perform health checks and failover routing for high availability.

2. Edge caching with Amazon CloudFront – CloudFront is a globally distributed CDN service that caches content at edge locations closer to end-users. It helps reduce latency and improves content delivery speed. CloudFront can be configured to distribute both static and dynamic content.

3. Edge security for Amazon CloudFront with AWS WAF –Filters malicious traffic, including cross-site scripting (XSS) and SQL injection via customer-defined rules.

4. Load balancing with Elastic Load Balancing (ELB) – AWS Elastic Load Balancers (ELB) distribute incoming web traffic across multiple EC2 instances to enhance fault tolerance and ensure your application is available and responsive. There are two types of ELBs: Application Load Balancers (ALB) and Network Load Balancers (NLB).

5. DDoS protection with AWS Shield – AWS Shield offers protection against Distributed Denial of Service (DDoS) attacks to ensure the security and availability of your web applications.

6. Firewalls with security groups – Moves security to the instance to provide a stateful, host-level firewall for both web and application servers.

7. Caching with Amazon ElastiCache – provides caching services with Redis or Memcached to remove load from the app and database, and lower latency for frequent requests.

8. Managed database with Amazon Relational Database Service (Amazon RDS) – RDS provides managed database services for popular database engines like MySQL, PostgreSQL, and others. It offers high availability and automated backups for your application's database.

9. Static storage and backups with Amazon Simple Storage Service (Amazon S3) – Amazon S3 can be used to store static website content, including HTML, CSS, JavaScript files, images, and multimedia. It provides high availability, scalability, and low-latency content delivery through integration with Amazon CloudFront, a Content Delivery Network (CDN).

This architecture provides a scalable, reliable, and secure environment for hosting web applications on AWS. The specific services and configurations you choose will depend on the unique requirements of your web application.
