PubNub vs SocketCluster: What are the differences?
- PubNub: PubNub is a global Data Stream Network (DSN) and Real-time Infrastructures-as-a-Service (IaaS) platform that enables developers to build real-time applications. It provides a set of APIs and SDKs that allow developers to send messages across various platforms in real-time.
SocketCluster: SocketCluster is a scalable real-time framework for building efficient and secure WebSocket applications. It provides a highly flexible and customizable platform for building real-time applications using the WebSocket protocol.
Scalability and Performance: PubNub is designed to handle large-scale real-time applications with millions of concurrent connections. It has a network of global data centers that ensure low-latency communication and high availability. SocketCluster, on the other hand, is built to scale horizontally and can handle thousands of concurrent connections efficiently.
Customization and Control: SocketCluster offers a high level of customization and control over the application's functionality. Developers can build custom middleware and plugins to extend the framework's capabilities. PubNub, while it provides a range of functionality out of the box, may have limited customization options.
Security: SocketCluster emphasizes security and provides features like access control, authentication, and encryption out of the box. It allows developers to secure their real-time applications using various mechanisms. PubNub also offers security features, but the level of control and customization may vary across different plans.
Development and Integration: PubNub provides a wide range of SDKs for various platforms and languages, making it easier for developers to integrate real-time functionality into their applications. SocketCluster also offers SDKs, but the availability may be limited compared to PubNub. It requires more manual configuration and setup.
In Summary, PubNub is a global Data Stream Network platform with extensive SDK support, while SocketCluster is a scalable real-time framework with high customization and security features.
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.
