|"Hello world" code example|
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|
tenefit.cloud allows clients to subscribe to Kafka topics to consume messages via a pub/sub paradigm. However, client apps cannot publish messages to Kafka.
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 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 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 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 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|
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.
Ably is integrated with most serverless functions providers. We support AWS Lambda, Azure Functions, Google Cloud Functions, IFTTT, Cloudflare Workers, and Zapier.Explore Ably's serverless functions implementation

Quality of Service
What QoS guarantees do Ably and tenefit.cloud provide natively?
API key authentication
The simplest way to authenticate. Involves using private API keys that you can usually create and edit via a dashboard. Recommended to be used server-side, as private API keys shouldn’t be shared with untrusted parties.
|Explore Ably's implementation of API key authentication|
Which popular token-based authentication mechanisms do Ably and tenefit.cloud support?
Note that token-based authentication is usually the recommended strategy on the client-side as it provides more fine-grained access control and limits the risk of credentials being compromised.
