CI Claude I. Cloud Consultant | GCP Small-Business (50 or fewer emp.) 3/25/2026 "Fully Managed Pub/Sub with Reliable, Low-Latency Global Scalability" 4.5/5 What do you like best about Google Cloud Pub/Sub? 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. What do you dislike about Google Cloud Pub/Sub? 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 problems is Google Cloud Pub/Sub solving and how is that benefiting you? Pub/Sub solves reliable and scalable event ingestion without the need for infrastructure management. Pub/Sub benefits me by the elimination of server maintenance and also simplifies distributed architecture which provides durable low latency messaging. 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. Review collected by and hosted on G2.com. What do you dislike about Google Cloud Pub/Sub? 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. What problems is Google Cloud Pub/Sub solving and how is that benefiting you? It’s helping us decouple different parts of our system and build event-driven workflows. For example, instead of tightly linking services, we can publish events (like logs, file changes, or external data such as AppsFlyer streams) and trigger downstream processing independently. This has made our system more scalable and resilient, and it allows us to react to events in real time; whether that’s sending alerts to Slack or triggering data processing jobs.

"Google Pub/Sub very reliable partner for event-driven systems" 5/5 What do you like best about Google Cloud Pub/Sub? 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. What do you dislike about Google Cloud Pub/Sub? 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. What problems is Google Cloud Pub/Sub solving and how is that benefiting you? I am able to publish the message as an event to my services instead of manually making network bounded call. This avoids manual wiring and takes the responsibility f availability and parallelism. On error we do not need to track the error requests and retrying manually, until we acknowledge the message after successful execution Pub/Sub keeps retrying every 10 minutes (default) and after certain retries it removes the specific message from the queue.

Community Health Worker Small-Business (50 or fewer emp.) 12/12/2025 ""Solid Choice for Event-Driven Systems"" 5/5 What do you like best about Google Cloud Pub/Sub? 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. What do you dislike about Google Cloud Pub/Sub? 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. What problems is Google Cloud Pub/Sub solving and how is that benefiting you? Pub/Sub solves the need for reliable, scalable messaging between services. It helps me decouple systems, handle high traffic smoothly, and build event-driven workflows without managing infrastructure. Review collected by and hosted on G2.com.

Software Engineer Mid-Market (51-1000 emp.) 2/5/2025 "Google Cloud Pub-Sub - Best Messaging Queue Service" 5/5 What do you like best about Google Cloud Pub/Sub? 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. What do you dislike about Google Cloud Pub/Sub? 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. What problems is Google Cloud Pub/Sub solving and how is that benefiting you? We are using Google Cloud Pub-Sub as a message queue for asynchronous message processing. It benefits us be decoupling the producer and consumer systems completely. It provides latency close to 100ms which is really great as compared to Kafka and Redpanda message queues.

Senior Staff Cloud Architect - APAC Mid-Market (51-1000 emp.) 5/22/2023 "High performing queue with room fine-tuning" 5/5 What do you like best about Google Cloud Pub/Sub? 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. What do you dislike about Google Cloud Pub/Sub? 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. What problems is Google Cloud Pub/Sub solving and how is that benefiting you? Pub/Sub is a backbone for asynchronous, event-driven application design. Practically every application we develop is event driven in some way hence we use Pub/Sub heavily. 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. What do you dislike about Google Cloud Pub/Sub? 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. What problems is Google Cloud Pub/Sub solving and how is that benefiting you? Pub/Sub feeds Dataflow / Apache Beam to then handle our Data and Analytics use cases. We are able to not worry about things with this as a queue, and focus our engineering efforts on the actual data, not operations. Review collected by and hosted on G2.com.
