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

  • Load Balancer: Client-side or service mesh integration

Architecture Pattern

  • Service registry pattern
  • Client-side discovery pattern
  • Health check pattern
  • Circuit breaker integration
