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. In this post, we will look at scalability.

While a focus on predictability may seem counterintuitive, when it comes to developing realtime functionality, performance isn’t simply about minimizing latency and bandwidth requirements. It’s also about minimizing the variance in them and providing predictability to developers. If you know Ably’s median global latencies and bandwidth will always be within specific operating boundaries it provides a level of certainty in uncertain operating conditions.

On July 14, Natan Solomon talked about NASA’s release of the James Webb Space Telescope images and Airbus’ Zephyr S breaking the record for the longest unmanned flight. He then covered how Canadian internet giant Rogers is providing credits to customers after a nationwide outage and Amazon’s Ring providing a record amount of footage and information to U.S. authorities in 2021.
