Layer 4 & Layer 7

TCP load balancing for raw throughput, and HTTP/S routing for host or path-based traffic rules in the same service.

Automatic Health Checks

Unhealthy backend instances are removed from rotation and brought back automatically once they recover.

SSL / TLS Termination

Offload TLS handshakes to the load balancer and keep backend traffic on the private network.

Included operations

How It Works

Create a load balancer

Choose the protocol, port, and balancing algorithm.

Register backend instances

Add the instance IPs that should receive forwarded requests and group them into a backend pool.

Configure health checks

Set the check path, interval, and healthy or unhealthy thresholds for automatic failover.

Point your DNS and go live

Create an A record pointing to the load balancer floating IP and put traffic in front of the pool.

Common Use Cases

High-Traffic Web Applications

Handle traffic spikes without leaving a single instance exposed as the bottleneck.

E-commerce peak trafficMarketing campaign launchesFlash sale events

API Gateways

Route API traffic across several instances with health checks and controlled entry points.

REST API clustersGraphQL endpoint poolsWebhook receiver farms

Rolling Deployments

Drain one backend, deploy a new version, then re-register it without exposing users to a full outage.
