The getting started guide is good, but it lacks some screenshots, which would have broken down the monotony of walls of text. The tutorials are essentially detailed step-by-step guidances that are easy to follow. Sadly they do not cover programmable steps and don’t provide any code snippets - they focus entirely on performing actions from the AWS console”. | 4.50 / 5 Getting started guides / 5 Information architecture and developer journey / 5 API reference documentation / 5 Readability, design and navigation / 5 Quality of code / 5 Breadth and quality of tutorials / 5 “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.“ |
Dashboard or dev console Reviewed by 3+ independent developers Sign up for free and explore Ably's pub/sub messaging platform | 4 / 5 Ease of use / 5 Stats and reports / 5 Functionality / 5 “The EventBridge console provides all the functionality you need for managing event-driven pipelines, rules, event buses, and targets. Additionally, it supports native integrations to ingest events from a few external, non-AWS event sources. This includes some popular SaaS platforms such as ZenDesk, Datadog, Segment, and more. The console is tricky to use for new starters, and you constantly have to switch to other AWS services, such as Cloudwatch (for stats and reports).” | 4.33 / 5 Ease of use / 5 Stats and reports / 5 Functionality / 5 “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.“ |

API structure Reviewed by 3+ independent developers | 4.25 / 5 API consistency across SDKs / 5 Well structured / 5 Intuitive / 5 Simple / 5 “EventBridge APIs are available as part of the AWS SDKs. They are largely consistent across programming languages, straightforward, and relatively easy to use. The API reference is detailed and includes plenty of examples. In any case, you’re probably better off interacting with EventBridge from the AWS console, since the product seems to be designed to be used this way primarily.” | 4.25 / 5 API consistency across SDKs / 5 Well structured / 5 Intuitive / 5 Simple / 5 “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 | ||
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 | Limited Amazon EventBridge integrates with Amazon SQS (Simple Queue Service) in order to provide message queues. | |
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 | ||
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 | ||
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 EventBridge only integrates with AWS Lambda Functions, but does not support other serverless platforms, such as Azure Functions or Google Cloud Functions. | 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. |
