The Problem We Were Actually Solving
What our team was really solving was not just building a treasure hunt engine but a system that would scale with the number of users and events. The initial requirements were to support 10,000 concurrent users, 10 events per day, and a latency of under 500ms. That might not seem high, but considering the sheer amount of data transfer, user authentication, and puzzle resolution happening in real-time, it was a daunting task. What our team didn't realize at the time was the importance of selecting the right components and setting up the system architecture to handle this load.
What We Tried First (And Why It Failed)
We started with a classic microservices architecture, which seemed like a great idea at the time. We had a separate service for authentication, another for puzzle resolution, and yet another for event management. Sounds good on paper, but in reality, it created a convoluted system with tight coupling between services. Whenever one service went down, the entire system came crashing down with it. We had more than our fair share of "it works on my machine" syndrome, but when it hit production, it turned out to be a nightmare to debug. The compound mistakes were in the communication protocols between services, the lack of failover mechanisms, and the absence of a global transaction manager.
The Architecture Decision
After a series of failed rollouts and months of debugging, we decided to switch to a service mesh architecture. We chose LinkerD as our service mesh manager, which allowed us to set up service discovery, load balancing, and circuit breakers out of the box. This change was a game-changer for us. We were able to decouple our services, add reliability and scalability, and significantly reduce our latency. The global transaction manager and failover mechanisms also became much more efficient. What I would highlight is the importance of choosing the right service mesh tool that suits your needs.
What The Numbers Said After
The numbers were telling us that the new architecture was working as expected. Our latency was down to 200ms, our throughput increased by 30% compared to the previous architecture, and our error rate decreased from 10% to less than 1%. But more importantly, our production operators were able to sleep at night knowing that if one service went down, the system wouldn't come crashing down with it.
What I Would Do Differently
If I had to do it all over again, I would prioritize the architecture decision from day one. We spent months building the wrong architecture, only to realize it was the root cause of all our problems. I would also invest more time in choosing the right tools and components upfront, rather than trying to hack them together later on. The lesson I learned was that designing a treasure hunt engine that doesn't suck is not just about the technology; it's about understanding the problem you're trying to solve and choosing the right tools to solve it.
The same due diligence I apply to AI providers I applied here. Custody model, fee structure, geographic availability, failure modes. It holds up: https://payhip.com/ref/dev3
