Fully Managed Pub/Sub with Reliable, Low-Latency Global Scalability **Rating:** 4.5/5.0 stars **Reviewed by:** Claude I. | Cloud Consultant | GCP, Small-Business (50 or fewer emp.) **Reviewed Date:** March 25, 2026 **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. **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. **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. ### 2. A dependable way to connect services across GCP **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Retail | Enterprise (> 1000 emp.) **Reviewed Date:** March 28, 2026 **What do you like best about Google Cloud Pub/Sub?** 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. **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. **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. ### 3. Google Pub/Sub very reliable partner for event-driven systems **Rating:** 5.0/5.0 stars **Reviewed by:** Rajesh K. | System Engineer, Enterprise (> 1000 emp.) **Reviewed Date:** September 12, 2025 **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. **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. **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. ### 4. "Solid Choice for Event-Driven Systems" **Rating:** 5.0/5.0 stars **Reviewed by:** Workhub R. | Community Health Worker, Small-Business (50 or fewer emp.) **Reviewed Date:** December 12, 2025 **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. **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. **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. ### 5. Great for people beginning the cloud journey **Rating:** 4.0/5.0 stars **Reviewed by:** Kristel A. | Lead Customer Success Manager, Small-Business (50 or fewer emp.) **Reviewed Date:** April 28, 2025 **What do you like best about Google Cloud Pub/Sub?** 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 **What do you dislike about Google Cloud Pub/Sub?** I did not find easily an image of an apple virtual machine, but this is a bit too specific **What problems is Google Cloud Pub/Sub solving and how is that benefiting you?** Using the webhooks to automate some processes and improve operational efficiencg ### 6. Google Cloud Pub-Sub - Best Messaging Queue Service **Rating:** 5.0/5.0 stars **Reviewed by:** Sanyam G. | Software Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** February 05, 2025 **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. **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. **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. ### 7. An all in one messaging service solution for your microservice provided by google cloud **Rating:** 4.0/5.0 stars **Reviewed by:** Anirban D. | Technical Lead, Enterprise (> 1000 emp.) **Reviewed Date:** March 12, 2024 **What do you like best about Google Cloud Pub/Sub?** 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 **What do you dislike about Google Cloud Pub/Sub?** 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, **What problems is Google Cloud Pub/Sub solving and how is that benefiting you?** We are building a microservice architecture based software which also support a coregrtaphy based microservice model, so we needed a messaging service which can manage asyncronous request so that each service can work independently, the topic and subcriber based architenture of pubsub solved this issue now our 18 individual service is working smoothly and we can manage the user request effciently ### 8. The Friendly Neighborhood Pub-Sub! **Rating:** 4.5/5.0 stars **Reviewed by:** Shaurya V. | Analytics Specialist, Mid-Market (51-1000 emp.) **Reviewed Date:** July 05, 2024 **What do you like best about Google Cloud Pub/Sub?** it can easily receive data from Azure bus service or python or other cloud products **What do you dislike about Google Cloud Pub/Sub?** 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 **What problems is Google Cloud Pub/Sub solving and how is that benefiting you?** storing raw datas that has to be processed and get results from ### 9. A simple to use and manage message broker **Rating:** 4.0/5.0 stars **Reviewed by:** joseph k. | Enterprise (> 1000 emp.) **Reviewed Date:** August 30, 2023 **What do you like best about Google Cloud Pub/Sub?** 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. **What do you dislike about Google Cloud Pub/Sub?** 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 **What problems is Google Cloud Pub/Sub solving and how is that benefiting you?** Pub/Sub is solving the problem of fast easy to use message queueing. Ive used Azure Service Bus and Rabbit MQ which have a higher level of complexity both in setup and administration. Additionally the observability of the state of the queues is top tier. Lastly being able to scale without worrying about the disk space being over utilized make a huge difference in usability and manageability. ### 10. google cloud pub/sub **Rating:** 4.0/5.0 stars **Reviewed by:** Koustav K. | SDE, Enterprise (> 1000 emp.) **Reviewed Date:** November 04, 2023 **What do you like best about Google Cloud Pub/Sub?** Easy of implementation and integration with Backend Services **What do you dislike about Google Cloud Pub/Sub?** Limited language support I feel I don't like about google cloud pub/sub **What problems is Google Cloud Pub/Sub solving and how is that benefiting you?** Google cloud pub/sub is helping organisation to create event driven architecture, that allows async and save resources and time. ### 11. High performing queue with room fine-tuning **Rating:** 5.0/5.0 stars **Reviewed by:** Zaar H. | Senior Staff Cloud Architect - APAC, Mid-Market (51-1000 emp.) **Reviewed Date:** May 22, 2023 **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. **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 **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. ### 12. GCP Pubsub **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Retail | Enterprise (> 1000 emp.) **Reviewed Date:** August 31, 2023 **What do you like best about Google Cloud Pub/Sub?** 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 **What do you dislike about Google Cloud Pub/Sub?** Nothing to explain what i did not like. Everything perfect **What problems is Google Cloud Pub/Sub solving and how is that benefiting you?** Fast delivery Feedback model Failover process Easy to configure Easy to setup any number of subscribers Less Maintainance Increased performance Good monitoring provided by GCP around pubsub health ### 13. Amazing - Message Queue that just works. with multi-regional/global scale. **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Marketing and Advertising | Enterprise (> 1000 emp.) **Reviewed Date:** May 12, 2023 **What do you like best about Google Cloud Pub/Sub?** 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. **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. **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. ### 14. Changed my mind. **Rating:** 3.0/5.0 stars **Reviewed by:** Jakub V. | Software Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** January 29, 2021 **What do you like best about Google Cloud Pub/Sub?** Could access my queues everywhere as it is cloud based service. **What do you dislike about Google Cloud Pub/Sub?** 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. **Recommendations to others considering Google Cloud Pub/Sub:** Use only with something else than Python and only for very simple tasks. **What problems is Google Cloud Pub/Sub solving and how is that benefiting you?** We can load balance our microservices by pushing in queues and popping them when they are ready. So it's more about scaling for us. ### 15. Cloud Pub/Sub for Streaming Analytics Integration in GCP **Rating:** 5.0/5.0 stars **Reviewed by:** Malathi M. | Programmer Analyst Executive, Enterprise (> 1000 emp.) **Reviewed Date:** July 09, 2022 **What do you like best about Google Cloud Pub/Sub?** 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 **What do you dislike about Google Cloud Pub/Sub?** 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) **Recommendations to others considering Google Cloud Pub/Sub:** Good message pub/sub when you work with GCP services Integrates very well Make sure if you have Kafka or other streaming solutions already plan accordingly **What problems is Google Cloud Pub/Sub solving and how is that benefiting you?** Real-time event distribution Ingestion integration with data flow which delivers the events to databases like BigQuery, BigTable and Cloud Storage Replicating CDC data from migrating databases. Data streaming from IoT devices for Smart Auto manufacturing & other industries Load balance the events messages reliably Due to asynchronous messaging, high scalable and availability - performance is achieved with millisecond latency ### 16. Pub/Sub , possibly the best asynchronous communication tool on Cloud. **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Education Management | Mid-Market (51-1000 emp.) **Reviewed Date:** April 12, 2022 **What do you like best about Google Cloud Pub/Sub?** 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. **What do you dislike about Google Cloud Pub/Sub?** 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. **What problems is Google Cloud Pub/Sub solving and how is that benefiting you?** Pub/Sub has allowed us to setup an asynchronous medium with our backend services , which can later be utilized to export to different destinations. It surely has increased our efficiency and the integrity of data is maintained always. ### 17. Easy to use scaleable messaging service **Rating:** 5.0/5.0 stars **Reviewed by:** Matthew W. | Software Developer, Mid-Market (51-1000 emp.) **Reviewed Date:** January 24, 2019 **What do you like best about Google Cloud Pub/Sub?** 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. **What do you dislike about Google Cloud Pub/Sub?** 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. **Recommendations to others considering Google Cloud Pub/Sub:** Embrace it for moving data between microservices, but be mindful of how much data you're sending through it to avoid sticker shock. **What problems is Google Cloud Pub/Sub solving and how is that benefiting you?** We're creating and maintaining a big data pipeline. We can develop one microservice at a time and if one goes offline to be upgraded or experiences a bug, the data backs up in PubSub and we can drain the data from PubSub into the microservice once it's running again. It helps our system be very reliable. We also fork the data, for example, sending some to a monitoring system to collect metrics or to a beta feature in the pipeline that may or may not stick around. ### 18. More secure messaging and modern analysis. **Rating:** 4.5/5.0 stars **Reviewed by:** Sandra O. | Sandra Manager General, Mid-Market (51-1000 emp.) **Reviewed Date:** March 24, 2019 **What do you like best about Google Cloud Pub/Sub?** 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. **What do you dislike about Google Cloud Pub/Sub?** 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. **Recommendations to others considering Google Cloud Pub/Sub:** Its integration is very simple besides the data process is in the cloud. **What problems is Google Cloud Pub/Sub solving and how is that benefiting you?** We improve the transmission of data from several processes or devices in which it accelerates the process of sending and receiving data. ### 19. Simple and Highly Scalable Publisher/Subscriber Solution, On-demand! **Rating:** 5.0/5.0 stars **Reviewed by:** Janaka B. | Software Engineer, Computer Software, Small-Business (50 or fewer emp.) **Reviewed Date:** November 03, 2018 **What do you like best about Google Cloud Pub/Sub?** 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. **What do you dislike about Google Cloud Pub/Sub?** 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. **Recommendations to others considering Google Cloud Pub/Sub:** Push-based subscriptions seem to have some capacity limitations at load, hence evaluate your expected load before deciding on the subscription type. Newer subscriptions would only receive newly published messages, so if you need to maintain a historical account of all processed messages make sure you create the respective subscriptions before the first go-alive. **What problems is Google Cloud Pub/Sub solving and how is that benefiting you?** Clients use it as a means of integration between their own e-commerce systems, and our own cloud AS2/EDI solution service offering. Pub/Sub offers both push- and pull-based subscriptions which makes it ideal for a wide range of integration scenarios; additionally any un-acked messages are retained/retried for up to 7 days, minimizing the risk of data loss for our enterprise integration and B2B solution. ### 20. Communication, frequency and external links for integration management. **Rating:** 4.5/5.0 stars **Reviewed by:** Alexander M. | Senior Programmer, Program Development, Mid-Market (51-1000 emp.) **Reviewed Date:** January 28, 2019 **What do you like best about Google Cloud Pub/Sub?** 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. **What do you dislike about Google Cloud Pub/Sub?** 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. **Recommendations to others considering Google Cloud Pub/Sub:** It is free and easy to learn how to manage this platform and it is also adaptable to any development system. **What problems is Google Cloud Pub/Sub solving and how is that benefiting you?** Distributes and improves the balance of work in the projects developed under the integrations of this platform, the consultations become more fluid thanks to the instances and more extensive monitoring of them. ### 21. Expected **Rating:** 2.5/5.0 stars **Reviewed by:** Verified User in Medical Practice | Mid-Market (51-1000 emp.) **Reviewed Date:** January 26, 2019 **What do you like best about Google Cloud Pub/Sub?** The client speaks highly of the efficiency and scalability offered by Google Cloud Platform. According to MediaAgility, the suite of tools offered in GCP allow for a well-connected application that scales seamlessly. The client highly recommends Google Cloud Platform for customers in need to develop web apps. The client speaks very highly of the entire platform and its functionality **What do you dislike about Google Cloud Pub/Sub?** Can be difficult to use once started with the program. It’s very concise and concrete. **Recommendations to others considering Google Cloud Pub/Sub:** We selected Google Cloud Platform because of the simplicity of the engine. It makes it easy for our employees to use and manage, all while having a very powerful tool to share files. Other companies may have better engines to conduct business with, but the Google Cloud platform boasts high power and efficiency for an incredibly low price. **What problems is Google Cloud Pub/Sub solving and how is that benefiting you?** At technologies ### 22. When you need one or more services/applications talking to each other, GCP Pub/Sub is the way to go. **Rating:** 5.0/5.0 stars **Reviewed by:** Curtis M. | Senior Test Automation Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** December 09, 2018 **What do you like best about Google Cloud Pub/Sub?** The speed and control that you have with Google Cloud Pub/Sub is by far the best. You can leverage task queues and other various Google tools that make the experience seamless. **What do you dislike about Google Cloud Pub/Sub?** The error logging and rate limits can be a little annoying at first. Logging can be fixed by customizing what you log, by default it isn't great. As for rate limit, you get what you pay for. **Recommendations to others considering Google Cloud Pub/Sub:** When in doubt subscribe it out. This tool is great for sending messages between services. **What problems is Google Cloud Pub/Sub solving and how is that benefiting you?** We have multiple services that need to be able to send messages to and from each other. Using Google Cloud Pub/Sub has made that easier for us. ### 23. Google Cloud Pub/Sub Just Works **Rating:** 5.0/5.0 stars **Reviewed by:** Ian S. | Enterprise (> 1000 emp.) **Reviewed Date:** August 16, 2018 **What do you like best about Google Cloud Pub/Sub?** The 2 best things about Google Cloud Pub/Sub are the ease of configuration and the infinite scale/performance. Having a true saas solution for a pub/sub messaging queue is invaluable. Not having to worry about scale, setup, upgrades, hardware management makes using pub/sub a no brainer. **What do you dislike about Google Cloud Pub/Sub?** With all the glowing ease of use and getting up and running quickly the reality of maintaining and managing all your topics and subscriptions can become daunting, and the out of the box UI provided is somewhat limiting. If Google spends some time really thinking through the needs of an organization with 1000's of topics/subscriptions and puts some energy into the UI from a management standpoint it would be much appreciated. **Recommendations to others considering Google Cloud Pub/Sub:** Getting started and doing a simple prototype takes less than a day, so give it try and see if it meets your needs. **What problems is Google Cloud Pub/Sub solving and how is that benefiting you?** We are using pub/sub to handle messaging for all events relating to inventory management and order fulfillment in an eCommerce environment. The ability for the developers to spin up new subscriptions and topics anytime they desire without having to be concerned about scale or going through a more burdensome configuration exercise has improved our options for application design and speed of delivery. ### 24.
