WebSockets have become a key technology for powering chat, live data, and other realtime experiences. But how reliable are they at scale? While WebSockets provide a foundation for low-latency communication, ensuring reliability, integrity, and fault tolerance requires additional work. In our latest article, we break down: ✅ What reliability means in a realtime context ✅ The components you need for a reliable WebSocket infrastructure ✅ How to decide between building yourself or using a PaaS like Ably Get the full story here 👇 https://hubs.la/Q02TX26N0

In distributed systems, the question isn't just "Will my data arrive?"—it's "How many times will it arrive?" Achieving exactly-once delivery is the gold standard, but it comes with significant engineering challenges. Why does it matter? 📈 As your system scales, the complexity grows exponentially, increasing the risk of message duplication and loss. Understanding the intricacies of pub/sub delivery guarantees is crucial for building reliable applications, and experiences such as chat. What can you do? 🔧 Explore practical engineering solutions like idempotent publishing and coordinated acknowledgments to maintain message integrity. Ready to tackle these challenges? 🚀 Discover how platforms like Ably ensure exactly-once delivery, allowing you to focus on innovation rather than infrastructure.

Stadion specialises in creating immersive fan experiences through its industry leading digital publishing platform. Find out why they chose Ably to meet their exacting realtime requirements when it came to platform performance, scalability and reliability, enabling them to realise their growth ambitions and to deliver seamless 'first-to-know' realtime experience to fans.

🎾 When Tennis Australia began the search for a new realtime provider ahead of the 2018 Australian Open, they knew the stakes were high. The organization’s advertising revenue depends on continuous, reliable delivery of scores, commentary, and videos to sponsorship partners. But to achieve that, key requirements needed to be met: ✅ Delivering realtime live experiences at scale requires robust infrastructure with clear uptime guarantees. 📈 Traffic for sports games is virtually impossible to predict, meaning the solution would have to scale quickly – and without warning. 📱Tennis Australia needed to guarantee a consistent experience across devices – even those without WebSocket support. Losing customers through poor data delivery was simply not an option for Tennis Australia. Instead, they turned to Ably. Read the full story to find out more 👇

When building realtime capabilities in applications including live data broadcast, push notifications, stream processing, and chat, it’s crucial that messages arrive where they’re needed, in the right order, and the expected number of times. In our latest blog, we delve into how this significant engineering challenge can be met with pub/sub systems to deliver these guarantees and answer questions like: ❓Why do we need guarantees in pub/sub? ❓What are the types of guarantee? ❓Which pub/sub delivery guarantees matter? ❓Are strict guarantees possible with pub/sub? ❓When are strict delivery guarantees necessary? 👇

Today’s fans are global and also, very often, 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. So, for fan-centric businesses to be successful, they need to build or buy the right realtime experience technology. In our recent blog, Ably CEO Matthew O'Riordan explores what a modern realtime experience platform looks like, and outlines the requirements you should look for when making this critical technology choice 👇
