Google Cloud Pub/Sub vs. Microsoft Azure IoT Central

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.

Microsoft Azure IoT Central has native integrations with Visual Studio (like pretty much all Microsoft products) making it pretty simple to publish apps to Azure App Service, where you can host all sorts of different applications. It does a really good job of storing large amounts of data (for instance, collected from IoT devices with various sensors) and it gets stored to multiple DBs. Azure IoT Central could improve by adding more customizations, as this would make troubleshooting the products easier and make future costs smaller and easier to predict.

• 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

• Documentation
• Support
• Good and approachable GUI
• Many types of subscription configurations

• Would be nice if the queue could be extended beyond 7 days.
• We found it a bit tricky replay unacknowledged messages when needed.

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.

I have never faced a single problem in 4 years.

It's very fast, can be even better if you use protobuf.

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.

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.

Before deciding to go with Microsoft Azure IoT Central, we considered Google, Datadog, and AWS alternatives. The reason we went with Azure was that the client was heavily invested in Microsoft technologies and Azure plays really well with other Microsoft products. The competitive products might be a little bit easier to set up, with more flexible pricing, but, the integrations with other Microsoft services were the deciding factor for our use case.

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.

• Increased Efficiency with reliable and Google managed services up all the time wit Disaster Recovery in place as well
• Definitely Lower costs being a cloud based solution and easier to setup
• Faster Project delivery and go to market plan for the business use cases basis this technology at the back end

• positive: connected huge number of machines as IoT devices and passed them through entire IoT pipeline until storage in a fairly short time
• negative: we spent some time figuring out some "less-used" services because they aren't documented well
