+
+## From Supabase to AWS
+
+[Supabase](https://supabase.com/) has become the go-to choice for developers who want to build fast.
+It gives you everything in one place — PostgreSQL, Auth, Storage, and Edge Functions — without needing to manage infrastructure.
+
+But as your product matures, new requirements appear that go beyond what Supabase’s all-in-one model can offer:
+
+- **Advanced database management** – high availability, read replicas, automated backups, and fine-tuned performance.
+- **Analytics and data warehousing** – integrating with data lakes and large-scale ETL pipelines.
+- **Enterprise-grade compliance and security** – meeting SOC, ISO, HIPAA, or FedRAMP standards.
+- **Granular IAM and networking** – unifying database access, APIs, and infrastructure under a single identity and policy system.
+
+That’s where [AWS](https://aws.amazon.com/) comes in. It offers a **best-of-breed ecosystem** — each component is purpose-built, scales independently, and integrates deeply with the rest of your stack.
+This guide walks you through how to migrate each Supabase component to its AWS counterpart — practically and step by step.
+
+---
+
+## The Migration Process
+
+Supabase’s integrated platform maps cleanly to AWS’s modular architecture:
+
+| Supabase Component   | AWS Equivalent                                 | Notes                                                     |
+| -------------------- | ---------------------------------------------- | --------------------------------------------------------- |
+| **Database**         | Amazon RDS / Aurora                            | Managed PostgreSQL with Multi-AZ, PITR, and replicas      |
+| **Auth**             | Amazon Cognito / BetterAuth / Auth0            | Centralized user management, SSO, and MFA                 |
+| **Storage**          | Amazon S3                                      | Object storage with IAM-based access and CloudFront CDN   |
+| **Functions**        | AWS Lambda + API Gateway                       | Event-driven compute for backend logic                    |
+| **Realtime**         | AppSync / EventBridge / API Gateway WebSockets | Live updates, subscriptions, or event streams             |
+| **Networking & IAM** | VPC + IAM roles/policies                       | Fine-grained control, security, and compliance boundaries |
+
+**Recommended migration order:**
+
+1. **Database** – foundation of everything.
+1. **Auth** – migrate user identities and sessions.
+1. **Storage** – move file assets and update access logic.
+1. **Functions** – redeploy backend logic.
+1. **Realtime and Networking** – finalize integration and optimize architecture.
+
+Always start in **staging**, validate each part, then proceed to production.
+
+### 1. Database → Amazon RDS / Aurora
+
+**Supabase:**
+Managed PostgreSQL with limited scaling and shared tenancy.
+
+**AWS replacement:**
+
+- **Amazon RDS (PostgreSQL)** – Multi-AZ, automated backups, PITR, read replicas.

+- **DynamoDB** – optional for NoSQL or key-value workloads.
+
+**Migration focus:**
+
+1. Export schema and data using `pg_dump`.
+1. Restore into RDS or Aurora (same Postgres version).
+1. Recreate extensions (e.g., `pgcrypto`, `uuid-ossp`).
+1. Validate schema and queries in staging.
+1. Reconnect applications with new connection strings.
+
+**Key advantages:**
+
+- Performance tuning and [CloudWatch metrics](https://aws.amazon.com/cloudwatch/).

+- Private networking and parameter groups.
+- Access to AWS analytics tools ([Redshift](https://aws.amazon.com/redshift/), [Athena](https://aws.amazon.com/athena/), [Glue](https://aws.amazon.com/glue/)).
+
+### 2. Auth → Amazon Cognito (or Alternatives)
+
+**Supabase:**
+[GoTrue](https://supabase.com/docs/guides/auth/auth-go-true)-based Auth with email/password and [OAuth integration](https://supabase.com/docs/guides/auth/social-login), connected to Postgres RLS.
+
+**AWS replacement:**
+
+- [Amazon Cognito](https://aws.amazon.com/cognito/) for user pools, federated identity, and SSO integration.
+- Alternatives like [BetterAuth](https://betterauth.com/), [Auth0](https://auth0.com/), or [Clerk](https://clerk.com/) if developer-experience is a priority.
+
+**Migration focus:**
+
+1. Export user data (emails, metadata, OAuth IDs) from `auth.users`.
+1. Import into Cognito User Pool.
+1. Configure OAuth providers (Google, GitHub, etc.).
+1. Update frontend SDKs and backend JWT verification.
+1. Require one-time user re-authentication after migration.
+
+**Key advantages:**
+
+- Deep IAM integration with AWS services.
+- SAML/OIDC support and MFA.
+- Fine-grained access control and security compliance.
+
+### 3. Storage → Amazon S3
+
+**Supabase:**
+S3-compatible object storage managed inside Supabase, with integrated access policies and signed URLs.

+**Migration focus:**
+
+1. Create an S3 bucket with IAM-based access.
+1. Copy data using `aws s3 sync` or `rclone`.
+1. Recreate folder structure and permissions.
+1. Update signed URL logic to use S3 pre-signed URLs.
+1. Add CloudFront for caching if needed.
+
+**Key advantages:**
+
+- Lifecycle policies, versioning, and encryption (SSE-KMS).
+- Regional redundancy and cost-based storage tiers.
+- Tight integration with Lambda, Athena, and Redshift.
+
+### 4. Functions → AWS Lambda
+
+**Supabase:**
+[Edge Functions](https://supabase.com/docs/guides/functions/edge-functions) built with [Deno](https://deno.com/) for lightweight APIs.
+
+**AWS replacement:**
+
+- [AWS Lambda](https://aws.amazon.com/lambda/) for event-driven functions.
+- [API Gateway](https://aws.amazon.com/api-gateway/) for HTTP endpoints.
+
+**Migration focus:**
+
+- Rewrite Deno functions in Node.js, Python, or Go.
+- Deploy via Lambda console, CLI, or IaC (Terraform/CDK).
+- Store environment variables in **Secrets Manager** or **Parameter Store**.
+- Connect Lambda to S3, DynamoDB, or EventBridge as needed.
+
+**Key advantages:**
+
+- Multiple runtimes and deployment methods.
+- Native observability via CloudWatch.
+- Scales automatically with demand.
+
+### 5. Realtime and Events → AppSync / EventBridge
