Solace Event Broker Features

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 Solace 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

Solace 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 Solace 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 Solace Appliance Event Brokers and Solace Software Event Brokers into many individual virtual event brokers to allow many separate applications to share a single Solace event broker while still remaining independent and separated.

Solace Event Broker Services have only a single message VPN. Solace 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 Solace Software Event Brokers or Solace Event Broker Services.
