|---|---|---|---|
|
Are your cluster’s VNet and Subnets properly sized to support the number of event broker services you’d like to create? |
Yes |
The number of event broker services that can be created in a cluster is limited by the available IPs in the VNET and its Subnet(s). Additionally, those chosen networking option (Kubenet or Azure CNI) changes how IPs from the VNET are utilized which affects how many event broker services can be created. Consider the size of your cluster’s network carefully, as it is not possible to change its size after creation. |
|
|
Have you configured the cluster’s node pools to use autoscaling? |
Yes No |
SAP recommends using the cluster autoscaler to ensure that there is sufficient capacity in the cluster to create event broker services with a minimum waste of resources. |
