“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.“

“Azure Portal allows you to configure and monitor event pipelines built with Event Grid. 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.“

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.”

“Event Grid APIs are split into data plane APIs and management APIs. The management APIs enable you to create, update, and delete Event Grid topics and subscriptions, while the data plane APIs enable you to post events to topics and consume events. The APIs are largely intuitive and consistent across SDKs. They’re also quite easy to use, but you need to familiarize yourself with them first, as there are tens of operations you can perform.“

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

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

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.

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.
