Google Cloud Pub/Sub Reviews & Product Details

Google Cloud Pub/Sub is fully managed and has global scalability with exactly once delivery. Pub/Sub can be used to build event driven systems without the need to manage infrastructure. All you do is create a topic, set subscriptions and trust messages will be delivered reliably with low latency. Review collected by and hosted on G2.com.

Pub/Sub has no multi-level dead letter queues, after configuring a dead letter topic, there's no automatic retry ffrom that dead letter queue. This means that once messages land there, you have to manually republish them. Pub/Sub also has ordering limitations, message ordering is only supported within a single region and requires partioning that is key-based. Pub/Sub has complex IAM and has no built in schema evolution tools. Review collected by and hosted on G2.com.

What I like most is how flexible it is for event-driven workflows. We use Pub/Sub in a few different ways across our stack; for example, streaming error logs into a topic that triggers a Cloud Function to send Slack alerts, and also passing event data from Appsflyer to trigger Cloud Run services. It’s been very reliable and scales well without us having to think about infrastructure. Once topics and subscriptions are set up, it just works in the background.

One downside is that it can be a bit hard to debug when something breaks in the pipeline. Since everything is asynchronous, you sometimes have to trace messages across multiple services (Pub/Sub, Cloud Functions, Cloud Run) to find the issue. Also, the UI isn’t the most intuitive when managing multiple topics and subscriptions. Review collected by and hosted on G2.com.

I like the scaling of GCP Pub/Sub irrespective of load or number of subscriptions. This helps building Fan-In Fan-Out, exactly-once delivery systems. Another unique selling point is configuration flexibility such as integrating with Google Cloud Storage, Eventarc triggers, schedulers, Cloud Run functions, etc. this solves the wiring bottlenecks between micro services. It guarantees ease of configurability and usability by exposing SDK, CLI commands and APIs, The GCP documentation of implementing the client code is excellent. I use the Pub/Sub everyday at my work. GCP's support for Pub/Sub is top tier because this is one of their highlighted products and it is worth the hype. Review collected by and hosted on G2.com.

Pub/Sub is more focused on Cloud native functionalities. If we think outside of GCP, there is no point in discussing the implementation. Review collected by and hosted on G2.com.

The service is entirely managed by Google, eliminating the need for users to provision, manage, or scale infrastructure or clusters. Review collected by and hosted on G2.com.

Pub/Sub gives at-least-once delivery. So messages can come twice, and you must write code to de-duplicate. Review collected by and hosted on G2.com.

Taking my first steps on the cloud was smooth as the interface is intuitive, the documentation is up to date and the tutorials are comprehensive. The cherry on the on top was being able to make mistakes and learn without having to pay as they provided some credits for new members Review collected by and hosted on G2.com.

I did not find easily an image of an apple virtual machine, but this is a bit too specific Review collected by and hosted on G2.com.

The best thing i like Cloud Pub-Sub is that it is a fully managed service and eliminates the need for us to manage its infrastructure. It is also self scalable as per throughout being received. It ensure atleast once delivery and is really easy to integrate both from producer and consumer perspectives. Review collected by and hosted on G2.com.

It is slightly more expensive than other messages queues such as Apache Kafka. It is not efficient in processing message sizes of more than 10 MB. Review collected by and hosted on G2.com.

I like the slick user interface and how easily we can setup , also support for both push and pull feature was great , mostly the push feature where it can just use a rest api we dont need to do any extra code changes in our exisiting sibcriber api Review collected by and hosted on G2.com.

Mostly the dead lettering part need to improve, and also in high load it can send two different message with same message id , which google need to improve, Review collected by and hosted on G2.com.

it can easily receive data from Azure bus service or python or other cloud products Review collected by and hosted on G2.com.

it doesnt load all of the heavy messages, you have to refresh multiple times and it's a probability that you will find the message you are looking for Review collected by and hosted on G2.com.

I like how easy pub/sub is to use out of the box, and how well the various google cloud products integrate with both consuming and producing data for Pub/Sub. Review collected by and hosted on G2.com.

It would be nice to be able to have namespaces within a project for topics. currently the namespaces appear to be global which is less ideal for when you have many applications that live in a project Review collected by and hosted on G2.com.

Easy of implementation and integration with Backend Services Review collected by and hosted on G2.com.

Limited language support I feel I don't like about google cloud pub/sub Review collected by and hosted on G2.com.
