High Priority Initiatives

1. Smart Container Termination

Implement intelligent container termination with graceful shutdown and state restoration support.

Key Features:

• Pre-termination State: Containers should be able to return a special status indicating they cannot be terminated immediately
• Restore Call Support: Network should support a restore operation to bring containers back from pre-termination state
• Graceful Shutdown: Allow containers to complete critical operations before termination
• Timeout Handling: Define timeout policies for containers in pre-termination state

Benefits:

• Improved data consistency and reliability
• Graceful handling of long-running operations
• Better resource management during high-load scenarios
• Reduced risk of data loss during container shutdown

Required for Huly Collaborator service to be used for.

2. Rust-based NetworkServer Coordinator

Rewrite the NetworkServer coordinator component in Rust for better performance, lower latency, and improved resource efficiency.

Motivation:

• Performance: Rust's zero-cost abstractions and efficient memory management
• Concurrency: Better handling of high-throughput concurrent requests
• Safety: Memory safety without garbage collection overhead
• Resource Efficiency: Lower CPU and memory footprint

Considerations:

• Maintain backward compatibility with existing APIs
• Ensure smooth migration path for existing deployments
• Consider using async Rust frameworks like Tokio
• Evaluate NAPI-RS for Node.js interop if needed

3. High Availability (HA) Support for Network Coordinator

Add high availability capabilities to ensure network coordinator resilience and continuous operation.

Key Features:

• Active-Passive Failover: Automatic failover to standby coordinator instances
• State Synchronization: Real-time state replication across coordinator instances
• Health Checks: Continuous monitoring and automated failure detection
• Split-brain Prevention: Consensus mechanisms to prevent conflicting states

Benefits:

• Zero-downtime deployments
• Automatic recovery from coordinator failures
• Improved system reliability and uptime
• Better handling of maintenance windows

4. Comprehensive Performance Testing Suite

Develop a robust performance testing framework to evaluate Huly Network under various load scenarios and identify bottlenecks.

Test Scenarios:

1. High Request Volume: Thousands of concurrent requests per second
2. Container Scaling: Dynamic scaling with hundreds of containers
3. Network Latency: Various network conditions and geographic distributions
4. Memory Pressure: Large payload transfers and memory-intensive operations
5. Failover & Recovery: Coordinator failures and recovery scenarios
6. Multi-tenant Load: Mixed workloads from multiple tenants
7. Long-running Connections: WebSocket and streaming connection stability
8. Cold Start Performance: Container initialization and warm-up times

Metrics to Track:

• Request latency (p50, p95, p99)
• Throughput (requests/second)
• Container startup time
• Resource utilization (CPU, memory, network)
• Connection pool efficiency
• Redis operation latency
• Error rates under load

---

5. Streaming Capabilities for Partial Data Transfer

Introduce streaming capabilities to enable efficient partial data transfer from containers to clients.

Use Cases:

• Large Response Payloads: Stream large datasets without loading everything in memory

6. Security and External Client/Agent Support

Enable secure external access to the Huly Network Server Hub, allowing trusted clients and agents outside the private installation to consume services safely.

Key Features:

• Authentication & Authorization: Implement robust token-based authentication (JWT, API keys) for external clients
• TLS/SSL Encryption: Enforce encrypted connections for all external communication
• Rate Limiting: Apply granular rate limits per client/agent to prevent abuse
• Access Control Lists (ACLs): Fine-grained permissions for external clients to access specific services
• Audit Logging: Comprehensive logging of external access attempts and activities

Security Considerations:

• Network isolation between internal and external traffic
• DDoS protection and request filtering
• Certificate management and rotation
• Secure credential storage and rotation policies
• IP whitelisting/blacklisting capabilities

Use Cases:

• Third-party integrations accessing Huly services
• Remote monitoring and management agents
• External webhooks and event consumers
• Partner applications requiring controlled access
• Mobile/desktop clients connecting from public networks

Benefits:

• Secure extension of Huly Network beyond internal networks

• Controlled exposure of services to external consumers

• Enhanced flexibility for hybrid deployment scenarios

• Support for distributed teams and remote workers

• Real-time Data Processing: Push incremental results as they become available

Other Important Tasks

Monitoring & Observability

• Add OpenTelemetry for monitoring/logging
