High-performant queue with global scope - no need to worry about provisioning, regions, etc. - just create topics/subscriptions and go ahead, it scales automatically. It's a backbone of event-driven applications in GCP. It's the backbone of GCP EventArc. You can natively connect Pub/Sub to trigger Cloud Run and Cloud Functions, as well as to stream directly from Pub/Sub to BigQuery.

For high-volume workloads it worth looking at Pub/Sub lite as way to save money in exchange for more capacity planning. Review collected by and hosted on G2.com.

Great queue in general - simple to understand and use. They started lean and added more functionalities as it went. Pub/Sub Lite can be fiddly though - while it can save you quite a bit of money, it requires careful capacity planning and lacks many built-in integrations (BQ Streaming, Push delivery for Cloud Run/Functions). Again, Pub/Sub Lite is a potential money saver but not a drop-in replacement for regular pub/sub Review collected by and hosted on G2.com.

Easy handling of message transmission

99.99% delivery of messages to subscribers

Good Backout plan if something happens to GCP Servers

Fast delivery

Easy to connect with Feedback and make sure subscribers received Review collected by and hosted on G2.com.

Nothing to explain what i did not like. Everything perfect Review collected by and hosted on G2.com.

It just works. It is incredible for this to be 'serverless' be so full of features, and not require to administer any sort of cluster. This was been critical for helping us do more with streaming data. Review collected by and hosted on G2.com.

For massive scale data it can be expensive. We also compress our messages, so the 1KB message size minimum means - to optimize costs - we need to bundle messages. For some larger scale things, we rely on Pub/Sub Lite. Review collected by and hosted on G2.com.

Could access my queues everywhere as it is cloud based service. Review collected by and hosted on G2.com.

Changed my mind, going from 0 to 6. The product itself works, but that lack of documentation is disturbing. I experienced all sorts of weird behavior in Python. I solved some of them by using throttling, which wasn't described very well. And I still feel the system configuration I found in the end is very brittle. Review collected by and hosted on G2.com.

Fully managed Real-time streaming messaging service

Supports asynchronous communication with millisecond latency

Publish/Subscribe between producers and consumers

Load balancing, Highly available & auto-scaling capabilities

per message parallel processing workflows with Cloud functions

Great Service integration with Dataproc, Dataflow, BigTable, BigQuery, ClouStorage

Supports event-driven applications

Supports both Pull and Push message delivery patterns Review collected by and hosted on G2.com.

decoupling - the publisher doesn't have the proper acknowledgment of whether the consumers received the messages during asynchronous messaging

it is not suitable for huge volumes of data like audio, and video and doesn't support synchronous processing (eg: Video conferencing) Review collected by and hosted on G2.com.

Pub/Sub has all kinds of features and compatibility options, a Data guy would want in their toolset. We primarily use Pub/Sub to publish Avro message which are later published to GCS and Big Query. Review collected by and hosted on G2.com.

Probably the only downside of using Pub/Sub we faced was no support for schema evolution. A schema once fed into a Pub/Sub topic cannot be changed, which might hamper the overall workflow in cases of new changes. Review collected by and hosted on G2.com.

That it's easy to set up between apps I run in any region. My team can use it to send small messages that trigger things to happen, or to send large chunks of data around our global system. Review collected by and hosted on G2.com.

The price is a bit high per byte sent, which forces us to make sacrifices in terms of how many different apps we can send the data to and how much we can send. For example, monitoring metrics is a use case where we had to cut back on how many messages we sent to a microservice dedicated to collect the metrics via PubSub.

Asynchronous communication provides an incredible advantage in reading messages, this greatly facilitates the display in the tray without the need to reload the platform, the relations between publisher and subscriber allows the connection of the API of the platform in a secure manner. Review collected by and hosted on G2.com.

The distribution of notifications of events is somewhat excessive due to its synchronization with the platform and its database with the API, the loading of messages in the tray has a slight delay. Review collected by and hosted on G2.com.

The generous pricing model where there's a 10GB/month free quota for message payload sizing, and there's no other fees unless a message retention policy is configured or a subscription snapshot is created.

Push-based subscriptions make it quite easy to consume messages in an event-based pattern.

Google Cloud Functions natively support Pub/Sub as an event source, making it an ideal communication option for GCP-based serverless/FaaS computing systems for low-cost, event-driven, pay-per-execution compute provisioning. Review collected by and hosted on G2.com.

The API is somewhat confusing, as subscriptions can be manipulated at topic-level as well as globally (project-level) where the latter could lead to confusions.

Payloads need to be base-64 encoded before publishing (and decoded after retrieval) even if they are known to contain ASCII-compatible textual data

Can sometimes lead to unexpected charges, as Pub/Sub will automatically keep on retrying messages continuously, even if failures are due to permanent code-level issues. Review collected by and hosted on G2.com.

Very broad platform where you think of all available services, provides greater synchronization in the messaging of messages, connections to services and data systems installed inside and outside the platform, is easy to manage and integrate thanks to the keys that each platform has, you only activate the option and you will have it available. Review collected by and hosted on G2.com.

It is unfavorable the moments in which the platform is updated since sometimes the integrations fail since the configuration or the accesses change, as well as the transfers of files and messages. Review collected by and hosted on G2.com.
