Managing SD-WAN instances
An SD-WAN instance is the Kaspersky SD-WAN solution deployed on multiple physical and/or virtual devices for a single tenant. The instance underlies all key functionality of the solution, such as smart traffic control and protection of transmitted data. It is configured to meet your organization's requirements for flexibility, security, and performance when transferring data over the WAN.
Centralized configuration of SD-WAN instances is achieved using SD-WAN instance templates. You can specify all settings in an SD-WAN instance template and then use it when deploying instances for individual tenants, thus avoiding the need to configure them individually. To use an SD-WAN instance template when deploying an instance for a tenant, the tenant must be added to the template.
When you deploy Kaspersky SD-WAN for the first time, a default SD-WAN instance template is automatically created in the orchestrator web interface. It cannot be deleted, but you can select a different default template.
If you deploy the solution for a tenant that is not added to any SD-WAN instance template, the default template is applied to that tenant.
If the settings specified in the SD-WAN instance template do not match the actual settings of the tenant's instance, the solution is not deployed. For example, you may encounter an error when deploying the solution for a tenant if the SD-WAN instance template that is being used specifies the number of SD-WAN Controller nodes that differs from the actual number of nodes that the tenant has.
You can pool SD-WAN instances for scalability and fault tolerance, especially if a great number of devices is used.
Each SD-WAN instance pool is a load balancer with CPE devices as the load. When creating a CPE device, you can assign it to a pool of SD-WAN instances or to individual instances from that pool. If you assign a device to a pool of SD-WAN instances, the orchestrator automatically selects from this pool the SD-WAN instance with the least number of devices and assigns the device to that instance. If the quantities of devices are the same, the SD-WAN instance is selected randomly.
