# Service Discovery
|
|
|
|
## Overview
|
|
The Service Discovery component will provide dynamic registration, discovery, and health monitoring of services within the stock-bot platform. It will enable services to locate and communicate with each other without hardcoded endpoints, supporting a flexible and resilient microservices architecture.
|
|
|
|
## Planned Features
|
|
|
|
### Service Registration
|
|
- **Automatic Registration**: Self-registration of services on startup
|
|
- **Metadata Management**: Service capabilities and endpoint information
|
|
- **Instance Tracking**: Multiple instances of the same service
|
|
- **Version Information**: Service version and compatibility data
|
|
- **Registration Expiry**: TTL-based registration with renewal
|
|
|
|
### Service Discovery
|
|
- **Name-based Lookup**: Find services by logical names
|
|
- **Filtering**: Discovery based on metadata and attributes
|
|
- **Load Balancing**: Client or server-side load balancing
|
|
- **Caching**: Client-side caching of service information
|
|
- **DNS Integration**: Optional DNS-based discovery
|
|
|
|
### Health Monitoring
|
|
- **Health Checks**: Customizable health check protocols
|
|
- **Automatic Deregistration**: Removal of unhealthy instances
|
|
- **Status Propagation**: Health status notifications
|
|
- **Dependency Health**: Cascading health status for dependencies
|
|
- **Self-healing**: Automatic recovery procedures
|
|
|
|
### Configuration Management
|
|
- **Dynamic Configuration**: Runtime configuration updates
|
|
- **Environment-specific Settings**: Configuration by environment
|
|
- **Configuration Versioning**: History and rollback capabilities
|
|
- **Secret Management**: Secure handling of sensitive configuration
|
|
- **Configuration Change Events**: Notifications of config changes
|
|
|
|
## Planned Integration Points
|
|
|
|
### Service Integration
|
|
- All platform microservices
|
|
- External service dependencies
|
|
- Infrastructure components
|
|
- Monitoring systems
|
|
|
|
## Planned Technical Implementation
|
|
|
|
### Technology Stack
|
|
- **Service Registry**: Consul, etcd, or ZooKeeper
|
|
- **Client Libraries**: TypeScript SDK for services
|
|
- **Health Check**: HTTP, TCP, and custom health checks
|
|
- **Configuration Store**: Distributed key-value store
|
|
- **Load Balancer**: Client-side or service mesh integration
|
|
|
|
### Architecture Pattern
|
|
- Service registry pattern
|
|
- Client-side discovery pattern
|
|
- Health check pattern
|
|
- Circuit breaker integration
|
|
|
|
