Adding Shared Hosts

Deploy Hosts in one Tenant that can be accessed by Kubernetes (K8s) Pods in a separate Tenant.

Shared Hosts allow workloads to run on the same set of virtual machines (VMs), making better use of resources across multiple Tenants. DuploCloud now supports Services, Jobs, and CronJobs on shared Hosts, providing more flexibility for running long-running services, batch jobs, and scheduled tasks.

DuploCloud supports shared Hosts for:

• Services

• Jobs

• CronJobs
