Manage variable traffic loads on your application
Access reserved for users of the Managed Kubernetes® Service.
As your business grows and your application experiences more varied traffic, it is vital to maintain the same level of service. This is why cloud applications are usually built on distributed architectures that are spread out. They are more robust, and can easily handle peak loads. With our Load Balancer, you may securely and automatically balance your application’s load in real time, across several nodes.
The OVHcloud Load Balancer is designed to deliver a high level of availability and resilience, and is also based on its own distributed architecture.
Automated node management
If a node stops working properly, it is automatically removed from the list of available nodes for balancing. This means you can manage maintenance operations to encourage the prevention of downtime.
Directly integrated into Kubernetes
The Load Balancer delivers an interface that is directly compatible with Kubernetes. This means you can control your Load Balancer, with native tools.
Our Load Balancer solution is constantly being developed. Currently, the service is working with the following limits.
We will soon be able to offer more flexibility, and resources to suit greater requirements.
Create a Load Balancer
kubectl -f apply load_balancer.yaml
Delete a Load Balancer
kubectl delete service load-balancer
Create a Load Balancer in minutes, and update it almost instantly. This means you can be well-prepared for managing traffic spikes.
Create and manage your Load Balancer directly via Kubernetes.
Multiple health check protocols
Define the conditions for excluding a node to fit your criteria. You can choose from: standard TCP verification (already available), an application return code, or HTTP code (available soon).
To retain the sender’s initial address, the Load Balancer integrates Proxy Protocol. This means you can perform essential actions on the nodes such as IP address filtering, generating statistics, and analyzing logs.
IP address filtering
You can choose a filtering access policy by default, and provide a restricted list of IP addresses that can connect to your solution.
TLS encryption (coming soon)
Most applications communicate via a TLS encryption layer. Our Load Balancer integrates this layer using a certificate provided by the user, or managed by the service.
Private network connections
To keep your application nodes isolated on the private network, the Load Balancer can be used as a pathway between public addressing and your private networks, with the OVHcloud vRack.
Compatibility with instances (available soon)
The Load Balancer can manage several node types, like the containers provided by Kubernetes and standard instances operated by OpenStack.
What is load balancing in the cloud?
Load balancing is an operation that distributes the workload among several elements capable of performing the required task. In the cloud, load balancing is most often used for network connections that correspond to the load. These network connections are also known as service requests.
How does a load balancer work?
Load balancing follows rules set up by the operator. A flat or weighted distribution is most often selected when dealing with network connections alone. For example, when considering an application distribution, you can choose one according to routing rules depending on the content served, or user identification.
