Overview of PubSub+ for VMware Tanzu
Solace PubSub+ for VMware Tanzu provides high-performance, robust, enterprise-grade messaging technology over a wide variety of open protocols (including JMS, MQTT, REST, WebSocket), qualities of service (best-effort, guaranteed, transactions), and messaging patterns (publish/subscribe, request/reply, streaming, fan-in/fan-out).
PubSub+ event brokers support MQTT, which enable devices and applications running outside of VMware Tanzu to use the TCP Routes feature to connect with PubSub+ Messaging services running in VMware Tanzu. This feature provides endpoints that allow external connections. For more information, refer to the MQTT Tutorial. The Solace PubSub+ for VMware Tanzu documentation describes the TCP Routes feature.
PubSub+ Messaging supports High Availability (HA) configurations, where each event broker is assigned a backup that takes over in case of failures. The details about how to use this feature are in the Java Application tutorials. Be sure to read the API Best Practices and Configuring Connection Time-Outs and Retries documents.
In deployments where you are upgrading to version 9.8.0 or later, the event broker copies the contents of the existing certificate authority (CA) list to both the domain CA list and the client authentication CA list. The Certificate Authority must be managed from the event broker from versions 9.8.0 and later, and you must perform the following actions:
- Migrate from the certificate authority list to the new domain domain CA and client authentication CA lists.
- Delete the existing certificate authority list from your Tanzu Ops Manager.
For information about managing the new domain CA and client authentication lists, see Configuring the Domain Validation Certificate Authorities List.
