This is one of a series of posts that explain Ably’s four pillars of dependability. The four pillars project at Ably is about making concrete, objectively verifiable, statements about the technical characteristics of the service. We aim to ensure that our claims about service performance are expressed clearly in terms of explicit metrics, and we explain in technical terms how those performance levels are met.

When was the last time you used a chat service and noticed messages arriving out of order? It’s likely that you can’t think of one. Getting messages to arrive in the right order is more or less job number one of a chat service. Sounds simple. But scale this to millions of users across a global network and it becomes a complex distributed computing problem. Even at smaller scales, message ordering isn’t guaranteed once you go beyond a simple, direct connection between two users.

Consumption-based pricing has become a popular model for SaaS and PaaS businesses, allowing customers to pay only for what they use. Pioneers like Slack and AWS have successfully adopted this approach, offering flexibility and reducing waste. However, not all consumption-based models are created equal. The Monthly Active Users (MAU) model, while appealing in its simplicity, often leads to inefficiencies and unexpected costs.

Kafka is a highly popular realtime data streaming platform, renowned for handling massive volumes of data with minimal latency. Typical use cases include handling user activity tracking, log aggregation and IoT telemetry. Kafka’s architecture, based on distributed partitions, allows it to scale horizontally across multiple brokers. But although Kafka excels at high data throughput, scaling it to manage thousands of client connections can be costly and complex.

Today’s fans are global - often based across the world from their favorite team, sports star, or artist; and they are also virtual - for example, 99% of NBA fans across the world will probably never set foot in an arena. These trends are driving a shift in not only fan behaviors, but also expectations. Fans engaging in live events virtually rely on applications to deliver rich realtime experiences with such low latency and reliability that it can almost replace the in-person experience.

Tom Camp, DevRel Engineer at Ably takes you through a tutorial of adding an avatar stack to your application using Ably's latest product, Spaces. An avatar stack is a visual representation of a user’s presence - showing them as online and connected. They are the most common way of showing the online status of members in an application by displaying an avatar for each member. Events are emitted whenever a member enters or leaves a space, or updates their profile data.

In this WebSocket tutorial, Alex Booker from Ably (@CodeCast) teaches you how to implement realtime updates in your React applications. Here, we use React on the frontend and Node on the back to build a live cursors feature from scratch, but the fundamental WebSocket lessons can be applied to any manner of realtime application. WebSockets are a bidirectional full-duplex communication protocol used to enable realtime updates such as chat, multiplayer collaboration, notifications, and other live updates in your React applications.

What do Microsoft Word and Adobe have in common? Both had their established market spaces completely disrupted by new entrants that brought realtime collaboration to the user experience. Whilst the barrier to entry for adding features akin to Figma, Google Docs, and Miro had been high, it is now possible to build new collaborative applications, or even simply add collaborative features to existing applications - without building the realtime infrastructure.

When Figma arrived with multiplayer editing back in 2016, it wasn't at all obvious it would be successful - in fact, designers kind of hated the idea of "hovering art directors". Fast forward to 2023, and designers can't imagine another way.

I watch sports for a living. I couldn't tell you the last time I watched a baseball game from beginning to end. Data is one of the most valuable resources around. But data is no longer something that languishes in a database to be looked at later. Like sports events, data is now live. The sports industry can reap and build on innovations in the realtime data space. But this is no long a nice-to-have. Driven by changing fan behaviour this is now a commercial imperative.
