Architecture Overview

System Architecture

Secan follows a modern client-server architecture designed for efficient Elasticsearch cluster management.

Component Breakdown

Frontend (React)

• Dashboard: Visual overview of cluster health and metrics
• Cluster Management: View and manage cluster settings
• Index Management: Create, delete, and configure indices
• Shard Management: Monitor and manage shard allocation
• REST Console: Interactive API exploration tool

Backend (Rust)

• HTTP Server: High-performance Actix-web server
• Authentication: Support for multiple auth methods (Basic, OAuth, API Keys)
• Request Routing: Intelligent routing to appropriate handlers
• Caching: Intelligent caching for frequently accessed data
• API Proxying: Secure communication with Elasticsearch clusters

Elasticsearch Cluster

• Nodes: Multiple nodes for redundancy and scalability
• Shards: Distributed data storage and processing
• Replicas: Data redundancy and fault tolerance
• Indices: Organized data structures for efficient querying

Data Flow

1. User Interaction: User interacts with React frontend
2. HTTP Request: Frontend sends HTTP request to backend
3. Authentication: Backend validates user credentials/tokens
4. Request Processing: Backend routes request to appropriate handler
5. Elasticsearch Query: Backend queries Elasticsearch cluster
6. Response Processing: Backend processes and caches response
7. UI Update: Frontend receives response and updates UI

Security Architecture

• Authentication Layer: Protects backend endpoints
• Encryption: HTTPS for data in transit
• Token-based Auth: Support for JWT and API keys
• Request Validation: Input validation on all endpoints
• Audit Logging: Track all administrative actions

Scalability Features

• Stateless Backend: Easy horizontal scaling
• Connection Pooling: Efficient resource utilization
• Request Caching: Reduced load on Elasticsearch
• Multi-cluster Support: Manage multiple Elasticsearch clusters
• Async Processing: Non-blocking operations for better throughput
