But even those earliest models relied on binding platforms

It’s not that the software developer does not care  appliance repair center about the quality of service — that’s not what Pandey is implying here. He’s explaining that the glue that binds functions together in a singular application, has been replaced over the years in evolutionary surges: starting with the collective binding of the source code, with multiple sets of dynamically linked functions, then with Web services contacted using REST API calls, and now with something else entirely: the network overlay. In this extremely distributed model, where every component is a virtual appliance with a network address, the gaps between networked functions may be immeasurably small, or they may be the size of the planet.

None of the activity that brings these functions together as a cohesive unit, is the concern of any of the software developers responsible for these unlinked functions. In most cases, they invoke functions with little more concern than they had when they wrote GOSUB 900.

But even those earliest models relied on binding platforms, such as a common operating system, or some shared stretch of infrastructure. In today’s networked environments, distributed functions no longer share anything but a protocol to contact one another — a common interface. So the methodologies for threading distributed functions and microservices together, to borrow a phrase that may have special meaning to regular readers of ZDNet Scale, have been all over the map.
