Features

• Microservice Frameworks - Provides a comprehensive framework for building resilient, production-ready distributed microservices in Go.
• gRPC Data Streaming - Provides high-performance bidirectional and server-side data streaming using the gRPC protocol.
• Layered Architectures - Employs a domain-driven layered architecture to isolate core business logic from technical infrastructure.
• External Configuration Loading - Loads application settings from external remote sources to update system behavior without restarts.
• Remote Configuration Synchronization - Synchronizes application settings between remote stores and local files with automatic failover.
• Dynamic Configuration Management - Synchronizes application settings between remote stores and local files with automatic failover and reloading.
• Registry-Based Balancing - Distributes requests across healthy service instances based on real-time registration data and heartbeats.
• Middleware-Based Request Pipelines - Implements modular request pipelines to intercept and process network traffic for cross-cutting concerns.
• Inter-Service RPCs - Uses gRPC unary and streaming calls to exchange structured data between distributed backend services.
• Load Balancers - Distributes incoming network traffic across healthy service instances using various load distribution algorithms.
• gRPC Service Implementations - Implements gRPC service definitions and code generation for high-performance inter-service communication.
• Service Address Resolution - Maps standardized logical naming conventions to network addresses to locate services across a cluster namespace.
• Service Communication Libraries - Provides libraries for routing and serializing requests between internal microservice components.
• Identity Token Services - Uses cryptographically signed tokens to authenticate users and verify the origin of requests to service endpoints.
• Token-Based Authentication - Secures service endpoints using cryptographic tokens to verify identity and request origins.
• Go Microservices Architectures - Implements architectural patterns specifically tailored for building scalable distributed systems using the Go language.
• Resilience Patterns - Implements essential stability patterns including circuit breaking and rate limiting.
• Service Discovery Registries - Maintains a dynamic registry of active service instances and health status for cluster-wide discovery.
• Etcd Integrations - Enables service instance registration and availability tracking using Etcd for distributed cluster traffic balancing.
• Domain-Driven Designs - Provides architectural support for aligning software design with business domains through layered organization.
• Service Middleware Pipelines - Implements composable middleware pipelines to handle cross-cutting concerns like logging, authentication, and tracing.
• Distributed Locks - Provides global locks to coordinate access to shared resources across multiple service instances.
• Service Scaling - Automatically adjusts the number of running service instances to match workload demand.
• Request Rate Limiting - Prevents system overload by capping the number of incoming requests using rate-limiting patterns.
• Push Notification Managers - Coordinates a gateway and logic server to manage real-time connections and delivery of push notifications.
• Gateway-Based Request Routings - Implements routing rules at the API gateway to direct external requests to specific versions of internal services.
• Real-Time Message Push - Manages persistent connections to push real-time updates and notifications to clients via Go-based gateways.
• Tracing Context Propagation - Injects and extracts distributed tracing headers across network boundaries to maintain request correlation.
• Circuit Breakers - Protects the system from cascading failures by stopping requests to dependencies that become unresponsive.
• Task Execution Engines - Ships a task execution engine that decouples job submission from processing via persistent worker pools.
• Worker Pool Models - Implements a worker-pool execution model to process tasks asynchronously and increase system throughput.
• Centralized Logging Systems - Aggregates and indexes logs from distributed service components to enable efficient troubleshooting.
• Application Logging - Provides application-level logging with automatic file rotation and request context tracking.
• Distributed Observability Systems - Provides a unified observability environment for tracking requests and identifying bottlenecks via distributed tracing.
• Distributed Tracing - Tracks requests across multiple services using unique identifiers to analyze latency and execution flow.
• Service Health Monitoring - Tracks the operational status and performance of internal application services via health check interfaces.
