The pitfalls of using location streams as an interface for building live location features

Developers build live location features in their product because it is core to their business. In the process, they end up having to build infrastructure. Developers who have built and operated this underlying infrastructure on their own have a deeper experience of the pains involved. Often, this is the first time they start questioning if that part of the stack is core to their business and if there is an API for that. In the chance that they find HyperTrack as that API they were dreaming of, a new problem arises.

In many in-house location stacks, the de facto interface at which the infrastructure stops and the feature begins is the location stream. You generate the location stream on the device, log/store it on the server, and then consume it in the product. For enterprises using vehicle tracking systems (VTS) and GPS chips, there is a legacy reason to go down this path. When other teams and software modules in the stack are consuming this stream, it is hard to imagine ripping it out and replacing it with HyperTrack SDKs and APIs.

And then begins: “But it does solve a bunch of things we are dealing with”, “Hey they seem obsessed with it and we are not, they must know something we don’t”, “Let’s deploy it on that new feature or new set of users in that new project”, “Let’s run this in parallel with our stack and compare the results before phasing it in”, etc.

It is then that one of the two questions comes up:

  1. “Can we provide our location stream as input to your API and get your location stream as output?”
  2. “Can we use your location stream as input to our API and everything upstream will start working better?”

Tl;dr – Bad idea. Using location streams as the interface is architecture debt. Pay it off.
