Freemycloud

Introduction

Freemycloud is an open‑source cloud storage platform that enables individuals and organizations to host, manage, and share files and applications across distributed networks. It was conceived as a flexible alternative to proprietary commercial services, emphasizing user control, privacy, and extensibility. Freemycloud is available under the GNU Affero General Public License, which permits free use, modification, and redistribution while requiring that derivative works remain open source. The project has attracted contributors from a range of disciplines, including software engineering, cybersecurity, and community management, resulting in a robust and continually evolving code base.

History and Background

Origins

The concept of freemycloud emerged in 2014, during a series of workshops on decentralized storage. A group of developers led by lead architect Maria Santos identified a gap between the security concerns of traditional cloud providers and the performance limitations of peer‑to‑peer file sharing. Santos and her colleagues set out to create a platform that would combine the resilience of distributed systems with the manageability of centralized services.

Early Development

The first public release, version 0.1, was published in early 2015. It included basic file storage and retrieval functions, a simple web interface, and a RESTful API. The community responded positively, providing early feedback and additional feature requests. Over the next two years, freemycloud transitioned from a proof of concept to a production‑ready platform, adding authentication, encryption, and multi‑tenant support.

Key Features

Storage Management

Freemycloud allows users to upload, organize, and download files through a hierarchical folder structure. The system supports file metadata tagging, version history, and bulk operations such as copy, move, and delete. Storage quotas can be enforced at the user or group level, ensuring fair resource allocation.

Access Control

Granular permissions are enforced via a role‑based access control (RBAC) model. Permissions can be assigned at the folder or file level, and inherited through the hierarchy. Custom roles can be created to match specific organizational needs. In addition to user roles, group policies and dynamic access rules based on IP address or device fingerprinting are available.

Encryption

Data is encrypted both in transit and at rest. TLS 1.3 is used for all network traffic, while AES‑256 in GCM mode secures stored data. Users can opt for client‑side encryption, providing an additional layer of privacy. The platform also supports key rotation and automatic key management via integration with external secrets managers.

API and SDKs

Freemycloud exposes a comprehensive RESTful API that supports CRUD operations, metadata management, and lifecycle hooks. SDKs in Python, Java, JavaScript, and Go are maintained, facilitating integration with third‑party applications. Webhooks and callback endpoints enable real‑time notifications for events such as file uploads or permission changes.

Extensibility

The architecture is plugin‑based, allowing developers to extend functionality without modifying core code. Plugins can add new authentication backends, custom file processors, or integrate with external services like email, messaging, or CI/CD pipelines. A marketplace of community‑contributed plugins is available on the official website.

Multi‑Tenant and Container Support

Freemycloud can run as a single deployment that isolates tenants via logical namespaces. Docker images and Helm charts simplify deployment in containerised environments. Kubernetes operators are available for automated scaling, health checks, and self‑healing capabilities.

Audit Logging and Compliance

All actions are recorded in immutable logs, with optional integration into blockchain networks for tamper‑proof audit trails. The platform offers built‑in compliance checks for standards such as GDPR, HIPAA, and ISO 27001, including automatic data residency controls and export controls.

Technical Architecture

Overall Design

Freemycloud follows a layered architecture consisting of the following components: user interface, API gateway, application logic, storage engine, and persistence layers. The application logic is written in Go, chosen for its concurrency model and performance. The storage engine utilizes a distributed file system built on top of Ceph RADOS, enabling data replication, erasure coding, and self‑healing storage pools.

Authentication and Authorization

Authentication is handled by an external OAuth2 provider or an in‑house identity service. Once authenticated, a JSON Web Token (JWT) is issued and used for subsequent API calls. The RBAC engine validates the JWT claims against permission tables stored in PostgreSQL, a relational database that also holds user and group data.

Data Flow

User uploads file via web UI or API.
File is streamed directly to the Ceph cluster, bypassing local storage to reduce I/O bottlenecks.
Metadata is written to PostgreSQL.
Encryption keys are fetched from the secrets manager.
Post‑upload hooks trigger any active plugins.

Scalability and Performance

The platform supports horizontal scaling of application nodes through Kubernetes deployments. The storage backend is inherently scalable, allowing the addition of storage nodes without downtime. Load balancing is handled by an ingress controller, which distributes traffic across API gateways.

High Availability

All critical services run in active‑active configurations. Ceph’s replication and erasure coding guarantee data durability in the event of node failures. The application layer employs health checks and readiness probes; failed pods are automatically replaced by the orchestrator.

Backup and Disaster Recovery

Freemycloud provides built‑in snapshotting of Ceph pools and logical backups of PostgreSQL databases. Snapshots can be scheduled, retained, or archived to external object stores such as Amazon S3 or MinIO. Recovery scripts automatically restore data and configuration to a new cluster instance.

Security and Privacy

Threat Model

The platform assumes the presence of adversaries capable of network eavesdropping, compromised credentials, or malicious insiders. Security controls are layered to mitigate each threat vector, with the goal of achieving confidentiality, integrity, and availability.

Encryption Practices

Transport encryption uses TLS 1.3 with forward secrecy. At‑rest encryption is enabled by default for all object data. The key hierarchy follows a multi‑tier design: a master key stored in a dedicated secrets manager, with per‑tenant keys derived via HKDF. Keys are rotated quarterly, and logs capture rotation events.

Access Controls

Least‑privilege principle guides the default roles: admin, editor, viewer, and auditor. Custom roles can be defined with fine‑grained permissions. Temporal access tokens support short‑lived permissions for temporary collaborators. Two‑factor authentication (2FA) is mandatory for administrative accounts.

Audit Logging

All requests are logged with timestamps, source IPs, and user identifiers. Logs are written to an append‑only file and replicated to a separate immutable store. The optional blockchain integration hashes each event and writes the hash to a smart contract, providing tamper‑evidence.

Compliance

Freemycloud includes tools to assist with data residency, consent management, and right‑to‑be‑forgotten requests. Export controls are enforced via data classification tags, and policy enforcement points prevent data transfer to restricted destinations.

Community and Ecosystem
