“Azure Event Grid documentation is well organized in terms of information architecture, and the navigation is intuitive. The docs largely consist of quickstart guides, tutorials, samples, and Event Grid concepts. There’s also a useful comparison page with other similar Azure messaging services - Service Bus and Event Hubs. The tutorials are well written, with print screens and code samples throughout. However, they don’t cover the entire breadth of event sources and handlers that can communicate through Event Grid, which would have been incredibly helpful.“

Adding new events and handlers and managing them is easy enough, and the workflow is intuitive most of the time. You can also configure various logs, metrics, and alerts. All in all, the experience is good, but some tooltips would be good, so you don’t have to dig through the documentation if it’s the first time you’re using the service.“

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

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

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

The --mem-queue-size can be increased and messages can be written to disk; however, this is mainly an in-memory messaging platform.

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 

The only guarantee is that messages will be delivered at least once. However, it is possible to obtain idempotency with some client configuration.

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

Only integrates with Azure Functions. Event Grid doesn’t have in-built support for other serverless platforms, such as AWS Lambda or Google Cloud Functions.
