📂 Build Own Cloud

---

1. Client Access Layer

• Users can access the FileCloud instance via a web browser or mobile/desktop apps. Access is managed through role-based authentication and secure connections (HTTPS/TLS).

---

2. AWS Compute Layer: FileCloud Application Server

• EC2 Instance: Use an Amazon EC2 T2 Medium instance to host FileCloud. This instance type provides sufficient CPU and memory for optimal performance in a small to medium-scale environment.

  • FileCloud Installation: FileCloud application is installed here, including configurations for handling user authentication, data indexing, and UI.
  • FileCloud License: Upload a valid license file to activate FileCloud's full features.

• IAM Role: Attach an IAM role to the EC2 instance to securely manage access to Amazon S3 for file storage.

  • Security Group: Configure the EC2 instance's security group to allow inbound traffic on required ports (e.g., 80 for HTTP, 443 for HTTPS) and restrict other ports.

3. AWS Storage Layer: Amazon S3

• Primary File Storage: Configure Amazon S3 as the primary storage for FileCloud.

  • Storage Tiers: Utilize different S3 storage tiers based on data access frequency. For example:
    • Standard Tier: For frequently accessed data.
    • Infrequent Access: For less frequently accessed files.
    • Glacier: For archival storage to further reduce costs.

• Configuration Steps:

  • IAM User with S3 Access: Create an IAM user with the necessary permissions for S3 (GetObject, PutObject, etc.). Generate access keys to be used by FileCloud.
  • Cloud Config Modification: Update the cloudconfig.php file in FileCloud to set Amazon S3 as the storage endpoint, using the IAM user’s access credentials.

---

4. Data Governance and Security Layer

• Encryption: Enable S3 server-side encryption for stored data and use HTTPS/TLS for secure data transmission.
• Access Control Policies: Set up strict IAM policies to control access to FileCloud resources.
• Monitoring & Logging: Use AWS CloudTrail and Amazon CloudWatch to monitor access and changes to files, ensuring compliance and audit readiness.

---

5. Backup and Disaster Recovery Layer

• Automatic Backups: Schedule regular snapshots of the EC2 instance and periodic backups of critical FileCloud configuration files.
• Cross-Region Replication (Optional): Configure S3 Cross-Region Replication if required for additional redundancy, especially if serving a geographically diverse user base.

Architecture Diagram Outline

1. User ↔ HTTPS/TLS ↔ EC2 Instance with FileCloud Application (T2 Medium) ↔ IAM Role for S3 Access ↔ Amazon S3 (Multi-Tier Storage)

2. Monitoring & Logs: Integrate with AWS CloudTrail and CloudWatch for monitoring file access and system health.

3. Backup and Replication: Set up S3 Cross-Region Replication and EC2 Snapshots for disaster recovery.

Benefits of This Architecture

• Data Control and Security: Full data control with S3 storage and access control via IAM policies.
• Cost Optimization: Lower costs by utilizing various S3 storage tiers based on data access needs.
• Scalability: Leverage AWS's infrastructure for scaling storage independently of compute resources.
• Remote Access: Users can securely access files from anywhere, similar to traditional cloud storage services.

This architecture provides a secure, flexible, and cost-effective setup for a self-hosted cloud solution with enterprise-level data governance features, ideal for organizations seeking control over their data storage.
