A common problem that our customers have is event streaming spikey traffic to their clients. For example, imagine a server which needs to stream details on cryptocurrency trades. The quantity of trades happening each second is likely to fluctuate, sometimes nothing could happen, other times perhaps thousands. In order to ensure reliable communication, it’s important that rate limits are in place on how many messages are to be sent to subscribed clients.

Allow me to set a scene - You’re a speaker at a conference in a large venue. During your talk you’d like to poll your audience to find out whether they use a Mac, Windows or Linux. You’ve got an interactive chart in your slides which will update as the audience votes on your web app. But there’s a hitch, you — as the speaker, have access to a private WiFi, but your attendees don’t have that.

Jamstack has brought forward a great way to rethink the infrastructure of modern-day websites. It shows us just how much we can abstract away in the process of serving websites and, as a result, gain tremendous benefits to User and Developer Experience. However, much confusion exists around what kind of websites can actually fall under this classification.

Here at Ably, we deal with hard engineering problems all the time and pushing at the edges often results in us running up against all sorts of interesting gotchas. We recently made some AWS NLBs fall over, and had a hazardous encounter with Cassandra counter columns. In our day-to-day, we use gRPC for fast and efficient data exchange with mutual client/server state synchronization.

Everything that occurs is a change in state, or an event for short: the sun comes out, the bus arrives, plants emerge from the ground, a neighbor says hello, the calendar page turns to a certain date or time, or your team lead yells that you should get to da choppa. Among all events, the ones that must be observed, recorded, or otherwise acted upon can be categorized based on how timely the reaction needs to be.

It makes it easy to deploy, manage, and distribute data streams to third party developers as realtime APIs - so they can consume and integrate those data streams into their own apps. As realtime API adoption increases so does complexity, cost, and friction of integration for developers wanting to consume realtime data. But with API Streamer, out-of-the-box realtime API management tools and a proven cloud distribution network mean creating self-service realtime API programs has fixed initial (near-zero) and ongoing engineering cost.

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.
