controllers. Per Kubernetes, "controllers are control loops that watch the state of your cluster, then make or request changes where needed."

In Istio, we use the term a bit more liberally. Istio controllers watch more than just the state of *a* cluster -- many are reading from multiple clusters, or even external sources (files and XDS). Generally, Kubernetes controllers are then writing state back to the cluster; Istio does have a few of these controllers, but most of them are centered around...

The version being deleted on the source cluster needs to maintain state and ensure that the operation is mirrored to the target cluster prior to completing on the source object version. Since this needs to account for the target cluster availability and the need to serialize concurrent DELETE operations on different versions of the same object during multi DELETE operations, the current...

Depending on the number of previously existing objects, the existing objects that are now eligible to be replicated will eventually be synced to the target cluster as the scanner schedules them. This may be slower depending on the load on the cluster, latency and size of the namespace.

In the rare event that target DR site is entirely lost and previously replicated...

However, while we chose to use the xDS *transport protocol*, we chose to not use the xDS resource types, such as Clusters and Listeners.
In our experience and testing, these types force us to represent data in inefficient ways because they are general purpose.
Ztunnel is not general purpose; it has an extremely tight goal.

aggregating status across all pods, maintaining application availability, and
rollback.

     * Kubernetes clusters can now span zones within a cloud provider. Pods from a
service will be automatically spread across zones, enabling applications to
tolerate zone failure.
