In an example implementation consistent with the features disclosed herein, a tenant service in an internal network is made accessible to clients in an external network through a load balancer service. A request is transmitted by a tenant computing cluster in response to discovering creation of the tenant service at the tenant computing cluster. The request is received by a gateway computing cluster. The load balancer service is deployed at the gateway computing cluster in response to receiving the request. An external IP address for the external network is assigned to the load balancer service. The load balancer service is configured to forward client requests received at the external IP address to the tenant service. The external IP address is then sent to the tenant computing cluster.

Computing cluster load balancer

In an example implementation consistent with the features disclosed herein, high availability of a stateful application is achieved by orchestrating multiple computing clusters. A stateful application is deployed at a first application operator and a second application operator of a first computing cluster and a second computing cluster, respectively. The first application operator includes a first control loop that changes the first computing cluster based on first resources of the first computing cluster. The second application operator includes a second control loop that changes the second computing cluster based on second resources of the second computing cluster. Synchronization of the first resources with the second resources is configured, such as via an object storage service. The first application operator and the second application operator are scaled to, respectively, nonzero and zero. A load balancer is configured to route requests to the first computing cluster.

High availability computing clusters

Examples described herein relate to a system and method for deploying and managing services in tenant clusters using a management cluster. The management cluster includes an integration service in communication with a service controller. The integration service communicates with a service endpoint using privileged credentials for receiving tenant cluster-specific configuration information. The integration service generates access credentials for the new tenant cluster to communicate with the service provider. The integration service provides tenant cluster-specific configuration information and access credentials to the service controller for the deployment of the service in the new tenant cluster. The service controller deploys the service at the new tenant cluster and manages the lifecycle of the service at the new tenant cluster.
