RAM - Resilient Adaptive Manager
Automated PostgreSQL failover and cluster management
What is RAM?
RAM (Resilient Adaptive Manager) is the management layer that orchestrates PostgreSQL clusters using RALE consensus. It provides automated failover, resource monitoring, and cluster health management for production PostgreSQL deployments.
Key Features
Resource Monitoring
Real-time monitoring of CPU, memory, disk, and network usage
Health Checks
Continuous health monitoring with automatic recovery actions
Multi-Zone Management
Manage clusters across multiple availability zones
PostgreSQL Integration
Native PostgreSQL integration with automatic configuration
RAM Architecture
RAM acts as the control plane for your PostgreSQL cluster, managing failover decisions, resource allocation, and cluster state. It integrates with RALE for consensus and provides a unified management interface.
Management Components
- •Cluster Manager: Orchestrates failover and manages cluster state
- •Resource Monitor: Tracks system resources and performance metrics
- •Health Checker: Performs continuous health assessments
- •Configuration Manager: Manages PostgreSQL and cluster configurations
Monitoring & Alerting
RAM provides comprehensive monitoring capabilities with built-in alerting and integration with popular monitoring systems like Prometheus and Grafana.

Getting Started
RAM is designed to work seamlessly with RALE and provides simple commands for cluster management. It's production-ready and battle-tested in high-availability environments.
