Frappe Cloud Architecture
Frappe Cloud is built using multiple open-source technologies that work together to provide application hosting, deployment automation, infrastructure management, and a modern user experience. Each component plays a specific role in delivering reliable and scalable Frappe applications.
Overview
Instead of relying on a single technology, Frappe Cloud combines the Frappe Framework, modern frontend tools, containerization, infrastructure automation, and management services to simplify application deployment and operations.
Core Technologies
Frappe Framework
Frappe Framework is the foundation of Frappe Cloud. It is a full-stack web application framework built with Python and JavaScript.
The framework provides essential capabilities such as:
- Database abstraction layer
- User authentication and permission management
- REST APIs
- Document-oriented architecture
- Background job processing
- Website and application development tools
Applications like ERPNext are built on top of the Frappe Framework.
Frappe UI
Frappe UI is a modern frontend library built with Vue.js.
It provides reusable UI components that help developers build responsive, single-page applications while maintaining a consistent user experience across Frappe products.
Agent
The Agent is a lightweight application built using Flask. It works together with Press to manage benches and sites.
It provides a command-line interface (CLI) that allows Press to communicate securely with servers for deployment, updates, monitoring, and management tasks.
Docker
Docker packages applications and their dependencies into lightweight containers.
Containerization provides:
- Consistent deployment environments
- Simplified application packaging
- Improved portability across servers
- Better resource isolation
Ansible
Ansible is an infrastructure automation tool used to configure and manage servers.
It automates repetitive operational tasks such as:
- Server provisioning
- Software installation
- Configuration management
- Deployment automation
- Infrastructure maintenance
Architecture Overview
A typical Frappe Cloud cluster consists of multiple services working together to host and manage applications.
The architecture generally includes:
- Application servers running Frappe sites
- Database servers
- Redis services
- Background workers
- Load balancing components
- Infrastructure management services
Each component is responsible for a specific part of the application’s lifecycle, helping improve scalability, reliability, and operational efficiency.
Scalability and Redundancy
Production deployments typically extend this architecture with additional redundancy.
Depending on infrastructure requirements, deployments may include:
- Multiple application servers
- Redundant databases
- High-availability networking
- Load balancers
- Failover mechanisms
These additions help maintain service availability and reduce downtime during infrastructure failures or maintenance.
