  ---

  ---

  ✅ Using AWS for Hosting the ClearMind App

  1. Frontend Hosting (Next.js App)

  Options:

  • AWS Amplify Hosting

    • Good for serverless JAMstack apps (static or SSR)

    • Auto-deploy from Git

    • Easy integration with Cognito, Lambda, etc.

  • Amazon CloudFront + S3 (for static export builds)

    • Host static files (images, pre-rendered pages) on S3

    • Use CloudFront as a CDN for global delivery

  • Elastic Beanstalk / EC2 + NGINX

    • Full control to run a custom SSR server

    • Overhead in config, but works for complex deployments

  • AWS App Runner

    • Simplified container hosting for web apps

    • Works great with Dockerized Next.js apps (SSR or API routes)

  ---

  2. Backend/API Layer (Edge Functions, tRPC)

  Options:

  • AWS Lambda + API Gateway

    • For serverless backend logic (Edge Function alternative)

    • Scales automatically, pay-per-use

  • AWS AppSync (GraphQL)

    • Use if you go with GraphQL instead of tRPC

    • Integrates with DynamoDB, Cognito, etc.

  • Amazon ECS or EKS

    • For containerized microservices (complex, enterprise use)

  ---

  3. Database Layer

  If you're not using Supabase, here are AWS options:

  • Amazon RDS (PostgreSQL)

    • Fully managed PostgreSQL, equivalent to Supabase DB

    • Use with pgAdmin, Prisma, Hasura, etc.

  • Amazon DynamoDB

    • NoSQL alternative (not ideal for relational content structures)

  • Amazon Aurora Serverless

    • PostgreSQL/MySQL compatible, scales with demand

  ---

  4. Authentication

  • Amazon Cognito

    • Handles email/password, OAuth, social logins

    • Works with Amplify or independently

    • Can replace Supabase Auth

  ---

  5. Payments

  • Still use Stripe (it’s not tied to AWS)

    • Webhooks can be hosted on Lambda or API Gateway

    • Store subscription status in RDS/Aurora or DynamoDB

🆚 AWS vs Supabase vs Vercel (Hosting Comparison)

✅ When AWS is a Good Choice

• You need full control over infrastructure

• You expect heavy or unpredictable traffic

• You’re comfortable managing services like Lambda, RDS, S3, CloudFront

• You want to keep all services under one ecosystem (Auth, DB, Backend)

---

❌ When AWS Might Be Overkill

• You’re early-stage and want to launch fast

• You don’t have a DevOps/cloud engineer on your team

• You’re not ready to manage IAM roles, VPCs, load balancers, etc.

---

👑 Recommendation

You can host your frontend on AWS Amplify and use RDS + Lambda for backend logic, but this will require more configuration and DevOps work compared to Vercel + Supabase.

For MVPs or small teams, consider:

• Start with Vercel + Supabase

• Migrate to AWS when scaling or if you need tighter control
