Distribute Traffic, Stay Online
RamNode Cloud Load Balancers spread incoming requests across multiple backend instances, so a single server failure does not take down your application.
What Is a Load Balancer?
A load balancer is a networking service that sits in front of a group of backend servers and routes incoming traffic across them. It hides the individual instances behind a single virtual IP and makes sure no single server becomes a bottleneck or a single point of failure.
RamNode Cloud Load Balancers are fully managed. You define the frontend listener, the backend pool of instances, and the health-check rules. The balancer monitors your servers, removes failed ones from the pool automatically, and keeps traffic flowing to the healthy nodes.
What Are Load Balancers Used For?
Any service that needs uptime, scale, or even resource distribution can benefit from a load balancer.
High Availability
If one backend instance fails, the load balancer stops sending traffic to it and routes requests to the remaining healthy servers.
Horizontal Scaling
Add more instances to the backend pool as traffic grows, and let the balancer distribute the load evenly across them.
Health Monitoring
Automatic health checks detect unresponsive backends and take them out of rotation without manual intervention.
SSL Termination
Handle HTTPS at the load balancer so your backend instances can focus on application logic instead of TLS overhead.
Sticky Sessions
Route repeated requests from the same visitor to the same backend instance when your application requires session affinity.
Public Entry Point
Expose a single, stable public IP and port from the balancer while keeping backend instances on private networks.
Why Use RamNode Cloud Load Balancers?
Managed service. No need to install or maintain Nginx, HAProxy, or Traefik yourself. The balancer is provisioned and monitored by the cloud platform.
Works with private networks. Backends can live on private IPs and still receive traffic from the public internet through the balancer.
Flexible protocols. Support for HTTP, HTTPS, TCP, and UDP listeners with configurable ports and backend pools.
API and CLI control. Create listeners, pools, and members through the cloud control panel, OpenStack CLI, or infrastructure-as-code tools.
Predictable pricing. Load balancers are billed hourly at a flat rate, capped at the monthly price. No surprise charges based on request volume.
