Features
PubSub+ event brokers include many valuable features that can power and protect an event mesh deployed across every environment and component of the distributed enterprise, to enable you to stream events across them all. Follow these links to learn more about some of the most valuable PubSub+ features, or scroll down to the Feature Index to see feature summaries and additional links.

|
Dynamic Message Routing |
Dynamic Message Routing (DMR) automatically determines the best way to route messages through your event mesh. DMR provides a means to interconnect instances of PubSub+ event brokers so that messages published by clients hosted by one broker can be consumed by clients hosted on another. DMR is the current best practice for setting up an event mesh. |

|
Event Broker Redundancy for High Availability |
PubSub+ event brokers can operate in high-availability (HA) redundant groups for fault tolerance. If one of the event brokers fails, or is taken out of service, the other one automatically takes over. |
|
|
Replication for Disaster Recovery |
You can put in place a disaster recovery solution for PubSub+ event brokers using data center replication. When replication is enabled, guaranteed messages that are published to a Message VPN with an active replication state at one data center are automatically propagated to matching Message VPNs with a standby replication state at another data center. Replication provides business continuity and allows mission‑critical applications to continue to function during a major service outage to a data center. |

Distributed Tracing |
Distributed tracing provides the ability to track an event all the way from the sending application, between event brokers, and to the receiving application. This allows an administrator to trace the lifecycle of an event as it travels through the event mesh. |
|
|
Message VPNs |
Message VPNs enable the virtualization of appliance and software event brokers into many individual virtual event brokers to allow many separate applications to share a single PubSub+ event broker while still remaining independent and separated. PubSub+ Cloud event broker services have only a single message VPN. PubSub+ Cloud allows you to quickly create multiple event broker services to segregate topics and client applications, |
|
|
Message VPN Bridging |
Message VPN bridges allow messages published to one Message VPN to be delivered to the linked Message VPN. |
|
|
Config-Sync |
For event brokers in HA redundant groups or in replicated data centers, Config-Sync automatically propagates changes in both system-level and VPN-level configurations so that the two brokers remain in sync. Guaranteed messaging must be configured and enabled on each broker. |
|
|
Message Replay |
Message replay allows an event broker to resend messages to new or existing clients that request them, hours or even days after those messages were first received by the event broker. |
|
|
Kafka Bridging |
Kafka bridging allows for the configuration objects to bridge between Kafka clusters and |
|
|
Multi-Node Routing |
Multi-Node Routing (MNR) allows multiple PubSub+ event brokers to be networked together so that Direct messages published from clients connected to one event broker can be delivered to clients connected to other event brokers. You can't use both DMR and MNR at the same time. MNR is not supported in PubSub+ Cloud. |
