follows a very simple principle: as long as one side connects the nodes, information can be propagated and synchronized. What do you mean? Let's take a look at what happens in the following experiment. Scenario One: Let's say we have 3 registries, we'll peer1, Peer2, and Peer3 each point serviceurl to another two nodes. In other words, Peer1, Peer2 and Peer3 are 22 registered with each other. Start the three service registries and point the Compute-service serviceurl to Peer1 and start

. This means that a single cluster will be able to centralize data from multiple datacenters into one location. An example of a multi-datacenter topology that can be used to support bulk load (batch loads) is shown below:Note that there is no communication connection between the two clusters above the figure, which may be of different sizes, with a different number of nodes, and this single cluster in the following section can mirror any number of sou

Controller manager and scheduler. To achieve this reliably, we are want to having one actor modifying state at a time, but we want replicated instances of th ESE actors, in case a machine dies. To achieve this, we is going to use a lease-lock with the API to perform master election. We'll use --leader-elect the flags for each scheduler and Controller-manager, using a lease in the API would ensure that's only 1 ins Tance of the Scheduler and Controller-manager is running at once.That is, Control
