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 Queues are supported only via the Lightstreamer JMS Extender, which connects to any third-party JMS server and makes JMS (Java Message Service) available on the Web. Any HTML page running inside a web browser and any Node.js application instantly become JMS clients, able to publish and subscribe on JMS topics and 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	Limited By default, Azure Service Bus cannot guarantee that messages are delivered in the order you want them to be processed by a subscriber at all times. You can theoretically force message ordering, but it comes at the expense of other features.
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 Can only trigger Azure Functions. Azure Service Bus doesn’t have in-built support for other serverless platforms, such as AWS Lambda or Google Cloud Functions.

Pricing model How are the Azure Service Bus and Lightstreamer pricing models calculated? Explore Ably's pricing model for our pub/sub messaging platform	Azure Service Bus comes in Basic, Standard, and Premium tiers. Basic tier pricing is calculated based on the number of messaging operations (any API call to Azure Service Bus) and costs $0.05 per million operations. Standard tier pricing is calculated based on: - number of messaging operations (first 13 million ops/month free, a base charge of $0.0135/hour and variable price depending on the number of ops - between $0.20 and $0.80 per million ops). - number of brokered connections (AMQP connections or HTTP calls to Service Bus) - depending on the number of connections, the price can be between $0.03 and $0.025 per connection/month. - number of hybrid connections & WCF relays. For hybrid connections, the monthly price is $9.782 per listener + a data transfer overcharge of $1/GB. As for relays, pricing is based on usage ($0.10 for every 100 relay hours) and messages ($0.01 for every 10.000 messages) Premium pricing is calculated based on hourly usage at $0.928 per hour. Please note that we have used the US as a reference point, but prices may vary by region and there are further differences based on the type of support package.	Lightstreamer has a complex and confusing pricing model. First, you must choose between the community edition (free) and the enterprise edition (paid). When you select enterprise, you must then opt between the Enterprise or the Enterprise Ultimate package (the latter includes all client APIs, superior message rates, and all features). On top of this, you must choose a licensing scheme, of which there are six options in total. Some examples: Perpetual Upfront per Server License, Monthly Pay-as-you-go Per Core-Hour License, Annual Upfront per Client Licence. Once you choose a licensing scheme, you must also choose a license type, such as Demo, Evaluation, Production, or Hot-Standby. There’s no transparency regarding cost estimation or concrete numbers (at least not on their website).

“The Lightstreamer community is small. There is some activity going on on the Lightstreamer forums - usually people raising issues and asking for clarifications that arguably should have been clear from the documentation. Beyond forums, the Lightstreamer community is basically non-existent. There are only about 30 threads in total on Stack Overflow, and, although there are over 140 Lightstreamer repos on GitHub, they barely have a few stars or open issues and almost no pull requests.“
