                   p.service2item__text There is only one instance of the service in the cluster, and Ignite guarantees<br> that the instance is always available. 
                   p.service2item__text In case the cluster node on which the service is deployed disconnects, Ignite automatically redeploys the instance to another node.

                   p.service2item__text The service is started on each node of the cluster. If the service is a cluster singleton, it is started in the first cluster node, and is redeployed to one <br>of the other nodes if the first node terminates.

                p.compute2__text Whenever cluster topology changes, Ignite will re-evaluate service deployments and may re-deploy an already deployed service on another node for better load balancing.
