    public static final class Protos.DomainInfo

implements Protos.DomainInfoOrBuilder 
     Describes a domain. A domain is a collection of hosts that have
 similar characteristics. Mesos currently only supports "fault
 domains", which identify groups of hosts with similar failure
 characteristics.
 Frameworks can generally assume that network links between hosts in
 the same fault domain have lower latency, higher bandwidth, and better
 availability than network links between hosts in different domains.
 Schedulers may prefer to place network-intensive workloads in the
 same domain, as this may improve performance. Conversely, a single
 failure that affects a host in a domain may be more likely to
 affect other hosts in the same domain; hence, schedulers may prefer
 to place workloads that require high availability in multiple
 domains. (For example, all the hosts in a single rack might lose
 power or network connectivity simultaneously.)
 There are two kinds of fault domains: regions and zones. Regions
 offer the highest degree of fault isolation, but network latency
 between regions is typically high (typically >50 ms). Zones offer a
 modest degree of fault isolation along with reasonably low network
 latency (typically <10 ms).
 The mapping from fault domains to physical infrastructure is up to
 the operator to configure. In cloud environments, regions and zones
 can be mapped to the "region" and "availability zone" concepts
 exposed by most cloud providers, respectively. In on-premise
 deployments, regions and zones can be mapped to data centers and
 racks, respectively.
 Both masters and agents can be configured with domains. Frameworks
 can compare the domains of two hosts to determine if the hosts are
 in the same zone, in different zones in the same region, or in
 different regions. Note that all masters in a given Mesos cluster
 must be in the same region.
 Complex deployments may have additional levels of hierarchy: for example,
 multiple racks might be grouped together into "halls" and multiple DCs in
 the same geographical vicinity might be grouped together. As a convention,
 the recommended way to represent additional levels of hierarchy is via dot-
 separated labels in the existing zone and region fields. For example, the
 fact that racks "abc" and "def" are in the same hall might be represented
 using the zone names "rack-abc.hall-1" and "rack-def.hall-1", for example.
 Software that is not aware of this additional structure will compare the
 zone names for equality- hence, the two zones will be treated as different
 (unrelated) zones. Software that is "hall-aware" can inspect the zone names
 and make use of the additional hierarchy.
