Welcome to the OnFinality Enterprise Nodes Series, where we take a deep dive into the infrastructure powering mission-critical blockchain applications.

In this first post, we explore the OnFinality Enterprise Load Balancer - a robust, institutional-grade service designed to intelligently distribute traffic across multiple blockchain nodes. It ensures high availability, optimal performance, and fault tolerance for applications interacting with blockchain networks.

Whether you're building a dApp, running indexers, or managing high-throughput transactional platforms, OnFinality’s Enterprise Load Balancer provides a scalable and secure way to interact with blockchain infrastructure - without managing the complexity of node orchestration yourself.

How It Works

Our load balancer sits in front of one or more clusters of blockchain nodes, managed and monitored by OnFinality. Incoming RPC or WebSocket requests are intelligently routed to the optimal backend node based on a combination of factors:

• Node health
• Geographic proximity
• Historical response time
• Current load
• Request Type (Trace, Full, or Archive)

In the event of node failure or performance degradation, the load balancer automatically reroutes traffic to healthy nodes - without impacting your application.

Key Features

Built-in high availability
Traffic is automatically rerouted away from unhealthy or unresponsive nodes, keeping your application online without manual failover.

Smart routing
Requests are directed to the closest and fastest node available, reducing latency and improving responsiveness for users around the world.

Save cost by routing traffic to archive or trace nodes only when they can’t be served by full nodes.

Supports modern protocols
Designed for both HTTP(S) and WebSocket traffic, making it compatible with a wide range of blockchain tools and services.

Intelligent caching
Selectively caching persistent chain data to speed up query performance

Live health & block monitoring
Each backend node is continuously checked for availability and performance, ensuring traffic is only routed to healthy instances. Requests are routed to nodes with higher block height, making sure you get the latest block fast.

Analytics & Insights
Complete access to our API Insights dashboard and performance monitoring solutions

Fine-grained access control
Restrict access to your endpoint with IP whitelisting, rate limits, and API key management, giving you control over how your service is used.
