If you want to stream high volumes of data, be it for ETL streaming or event sourcing, Google Cloud Pub/Sub is your go-to tool. It's easy to learn, easy to observe its metrics and scales with ease without additional configuration so if you have more producers of consumers, all you need to do is to deploy on k8s your solutions so that you can perform autoscaling on your pods to adjust to the data volume. The DLQ is also very transparent and easy to configure. Your code will have no logic whatsoever regarding orchestrating pubsub, you just plug and play. However, if you are not in the Google Cloud Pub/Sub environment, you might have trouble or be most likely unable to use it since I think it's a product of Google Cloud.
TIBCO Rendezvous is a fast and reliable mode of communication, although they are already outdated by TIBCO FTL, which is even more faster and reliable than it's predecessor. They are more suitable for communication between the TIBCO products as all the TIBCO suite of products support the TIBCO Rendezvous. They are more widely used by banks and stock ticker applications to broadcast the ticker information. Most of the applications support Java JMS mode easily and out of the box than the TIBCO Rendezvous. Hence the TIBCO software themselves have their own version of the JMS server called Tibco EMS ( Tibco Enterprise messaging service).
With a pub/sub architecture the consumer is decoupled in time from the publisher i.e. if the consumer goes down, it can replay any events that occurred during its downtime.
It also allows consumer to throttle and batch incoming data providing much needed flexibility while working with multiple types of data sources
A simple and easy to use UI on cloud console for setup and debugging
It enables event-driven architectures and asynchronous parallel processing, while improving performance, reliability and scalability
It serves all of our purposes in the most transparent way I can imagine, after seeing other message queueing providers, I can only attest to its quality.
It has many libraries in many languages, google provides either good guides or they're AI generated code libraries that are easy to understand. It has very good observability too.
Attending an official TIBCO classroom training, where you can have an active participation with an expert teacher, you can find the answers to all yours needs. In any case, if you are not satisfied on your requests, the teacher takes the time to find the best solution.
I had the opportunity to attend one and I could learn all features I needed for my business: now I can say TIBCO Rendezvous is very usable.
They have decent documentation, but you need to pay for support. We weren't able to answer all our questions with the documentation and didn't have time to setup support before we needed it so I can't give it a higher rating but I think it tends to be a bit slow unless you're a GCP enterprise support customer.
I never needed support for TIBCO Rendezvous. I always used it without any issue and until now I don't remember some situations where it interrupted its 24/7 uptime.
Having used Amazon Web Services SNS & SQS I can say that even if the latter may offer more features, Google Cloud Pub/Sub is easier to use. On the other hand, usage of SNS & SQS as well as documentation and troubleshooting is easier with the AWS solution. Since we are not using GCP only for Pub/Sub the choice depends on other variables.
You can just plug in consumers at will and it will respond, there's no need for further configuration or introducing new concepts. You have a queue, if it's slow, you plug in more consumers to process more messages: simple as that.
All a non-TIBCO based applications need to use the TIBCO Rendezvous APIs and reprogrammed to communicate with other application using the Tibco Rendezvous.
All applications and enterprises need to have an enterprise license to communicate with each other.
TIBCO offers their Rendezvous APIs in various programming languages. Hence any application can use these APIs to start using the Tibco Rendezvous. Although most application prefers not to as TIBCO Rendezvous is TIBCO 's closely guarded recipe.
