Prompt Title: AWS Deployment for Apolloe

To deploy your SaaS product "Apolloe" on AWS and meet your requirements, I recommend the following architecture:

1. Domain Setup:

   • Purchase the domain name apolloe.com if you haven't already.
   • Configure DNS settings to point the domain and its subdomains to AWS Route 53.

2. SSL Certificate:

   • Request an SSL/TLS certificate for the domain and subdomains using AWS Certificate Manager (ACM).
   • Verify the domain ownership and generate the SSL certificate for apolloe.com, api.apolloe.com, and app.apolloe.com.

3. Elastic Beanstalk Setup:

   • Create an Elastic Beanstalk (EB) environment for each app (landing page, API, and SaaS app).
   • Configure each EB environment to use the corresponding subdomain (apollo.com, api.apolloe.com, app.apolloe.com).
   • Configure the environment to use HTTPS with the SSL certificate obtained from ACM.

4. Auto Scaling and Load Balancing:

   • Enable Auto Scaling for each Elastic Beanstalk environment to handle traffic fluctuations.
   • Configure the scaling policies based on metrics such as CPU utilization or request count.
   • Use Elastic Load Balancer (ELB) in front of each environment for distributing traffic and ensuring high availability.

5. Security:

   • Enable AWS Web Application Firewall (WAF) to protect your applications against common web exploits.
   • Implement AWS Shield to safeguard against DDoS attacks.
   • Configure security groups and network ACLs to restrict access to necessary ports and services.
   • Implement IAM roles and policies to control access to AWS resources.

6. CI/CD Pipeline:

   • Set up a CI/CD pipeline using AWS CodePipeline and AWS CodeBuild.
   • Connect your main branch of the GitHub repository to trigger the pipeline on code merges.
   • Configure the pipeline to build and deploy your applications to the respective Elastic Beanstalk environments.
   • Include testing, code quality checks, and deployment validation steps in the pipeline.

7. Project Structure with Nx:

   • Utilize the capabilities of Nx to structure your project effectively.
   • Create separate apps within the Nx workspace for the landing page, API, and SaaS app.
   • Define shared libraries for reusable code, utilities, and components used across apps.
   • Leverage Nx's build optimization features to speed up development and deployment.

By following this architecture, you will have a scalable, secure, and automated deployment of your SaaS product on AWS. Each app will be accessible via the designated subdomains and served over HTTPS.
