Google Cloud Pub/Sub vs PubNub: What are the differences?
Developers describe Google Cloud Pub/Sub as "Global service for real-time and reliable messaging and streaming data". Cloud Pub/Sub is a fully-managed real-time messaging service that allows you to send and receive messages between independent applications. You can leverage Cloud Pub/Sub’s flexibility to decouple systems and components hosted on Google Cloud Platform or elsewhere on the Internet. On the other hand, PubNub is detailed as "Build real-time apps quickly and scale them globally". PubNub makes it easy for you to add real-time capabilities to your apps, without worrying about the infrastructure. Build apps that allow your users to engage in real-time across mobile, browser, desktop and server.
Google Cloud Pub/Sub and PubNub belong to "Realtime Backend / API" category of the tech stack.
According to the StackShare community, Google Cloud Pub/Sub has a broader approval, being mentioned in 75 company stacks & 17 developers stacks; compared to PubNub, which is listed in 43 company stacks and 12 developer stacks.
I am building an IoT application that will utilize connected air quality sensors to provide real-time indoor air quality in offices. I want to be able to share this data with a few different databases, etc.
Wondering if anyone has any advice on which real-time streaming API would be best for this sort of application, or even how I should think about it?
For IoT, we support MQTT along with websockets and SSE. The pattern you're suggesting that involves harvesting data from devices and soaking into a database is easy to achieve with one of the Ably integrations (Serverless functions/webhook) . Here are some tutorials to do things like this: https://ably.com/tutorials/reactor-event-zapier#step2-mqtt-ably
We use Pusher at www.justlearn.com. It works fine. When you reach more users, Pusher gets expensive. We use Pusher for live chat between users. Their software is easy to use. We have had issues with auth on Pusher.
