In 2017 I was maintaining a Node.js ecommerce server when a new project landed on my desk — an IoT platform for vehicle tracking devices. Thousands of devices, transmitting data continuously, with clients expecting real-time visibility into what the devices were reporting.
The Node.js server started showing its limits almost immediately.
Too many devices, too much real-time data, not enough throughput. Clients were seeing delays. Data was arriving late. The storage layer was struggling so badly the team was deleting the previous month's data every 30 days just to keep things running. And underneath all of it was a monolith — one large server doing everything, with no clean way to scale the parts that were struggling without scaling everything.
We needed microservices. We needed speed. We needed something built for this.
