Hi, Vladimir
The answer is in API docs: "Gets *locally deployed service* with specified
name." [1]
That means {IgniteServices#service(String name)} returns only locally
deployed instance or null.
{IgniteServices#serviceProxy(…)} returns proxy to call instances across the
cluster. Might be used for load-balancing.
