In the first week of the 2021 NFL season, a bettor was famously one win away from a $727k payday on an 16 leg parlay. The problem? They lost. In a parlay, your position is only as strong as your weakest bet. The bettor’s downfall was relying on the overmatched Detroit Lions. When it comes to sports gambling, what the bettor doesn’t see is the technology that powers these user-facing applications that make or break their payday. Building a real money gambling application is actually much more complicated than it seems. Not only do you need a stable, reliable payment processing system, but you also need a real-time processing engine that can support millions of concurrent users who are placing bets at the same time.
