“The documentation is overall disappointing. The API reference, some comprehensive FAQs, and some decent writing for SDK-specific guides are noteworthy highlights. However, the rest is not great. There is no navigation sidebar; all the various sections of the docs are individual articles that are listed on a menu page. Furthermore, the sections are not organized in a logical manner; it’s unclear where to start, and often hard to understand how the topics connect.  There are only a few GitHub tutorials, with some brief steps, but certainly not enough details. Overall, you get the feeling the documentation fails to deliver relevant bits of information, and getting started with Kaazing was far from easy.”

P: “The dashboard is easy to set up. You get a good overview of the stored data, so you can easily manage the database. Features such as webhooks, jobs, logs, API console and push notifications are easily accessible. Lack of performance metrics is a downside.”

O: “The dashboard has a clean and simple UI with management sections for the webhooks, jobs, logs, configs and API console. It also includes a browsing view.”

W: “The dashboard UI is easy to understand and self-explanatory. On the downside there is no informative metrics available but on the upside there is a lot of functionality and configurations options and the API console where you can send HTTP and GraphQL queries is a nice feature.”

“Kaazing offers SDKs in several different programming languages, and for different operating systems. The naming conventions make the APIs reasonably intuitive and simple to understand, and the extensive API references help a lot. The APIs are mostly consistent at a class level, which makes sense, since the WebSocket ones are basically modeled around the standard WebSocket API. Note that the client SDKs also provide additional protocol capabilities, such as AMQP and JMS, which is quite useful.”

Realtime features

Pub/Sub messaging

Pub/Sub is a design pattern that lets any number of publishers (producers) push messages to channels (also known as topics). Multiple subscribers (consumers) can subscribe to a channel to consume published messages.

Explore Ably's pub/sub messaging implementation

Limited

There is support for pub/sub messaging using LiveQueries in the Javascript SDK, which uses WebSockets to subscribe & publish to channels. But LiveQueries is limited to the Javascript SDK.

Message queues

A message queue is a form of asynchronous service-to-service communication. Messages are stored on a queue until they are processed. Note that each message is only consumed by one subscriber (consumer).

Explore Ably's message queues implementation

Presence

Presence enables you to track the online and offline status of devices and end-users in real time and to store their state. Essential for chat apps and multiplayer games.

Explore Ably's presence implementation

Limited

One could keep track of online clients by using the LiveQuery triggers to know whether or not a client is connected. But there is no built functionality for this.

Message history

Message history provides a means to retrieve previously published messages. For this to be possible, message data must be stored (persisted) somewhere.

Explore Ably's message history implementation

Limited

You can configure Kaazing WebSocket Gateway to hold recent messages for a topic in a last value cache. However, you are required to use a JMS-compliant message broker, such as RabbitMQ.

Connection state recovery (stream resume)

In the case of unreliable network conditions, clients may suddenly disconnect.Connection state recovery ensures that when they reconnect, the data stream resumes exactly where it left off.

Explore Ably' s connection state recovery implementation

Guaranteed message ordering

Ordering ensures that messages are delivered to consumers in the same order that producers publish them.

Explore Ably' s guaranteed message ordering implementation

Exactly-once semantics

Exactly-once is a system-wide data integrity guarantee that ensures each message is delivered to consumers exactly-once.

Explore Ably' s idempotent publishing implementation

Limited 

Idempodency enforcement exists, as an experimental feature that may not be appropriate for production.

Message delta compression

Message delta compression enables you to only send the changes from the previous message to subscribers each time there’s an update, instead of the entire message. Useful for use cases where there is a significant degree of similarity between successive messages.

Explore Ably' s message delta compression implementation

Native push notifications

Native push notifications can be used to deliver messages even when clients are offline. Useful for geolocation updates or news alerts.

Explore Ably's push notifications implementation

Webhooks

Webhooks provide a mechanism to get messages and other types of events (such as clients entering or leaving channels) pushed to your servers over HTTP.

Explore Ably's webhooks implementation

Serverless functions

A serverless function is essentially an isolated, single-purpose piece of code that is only executed when it’ triggered by an event. For example, you can use serverless functions to send a welcome message to clients when they become present on chat channels.

Note that serverless functions are usually fully managed by cloud vendors.

Explore Ably's serverless functions implementation

Limited

Cloud functions are used in parse server to run single-prupose piece of code. But is up to you to host the parse server, where the cloud functions are invoked from. The pricing model is different, since you are hosting the parse server yourself, you can invoke the cloud function for as many times as you like. Services like AWS Lambda charges you for the number of requests made and the duration of those requests.
