Get Small To Get Big

If we trace a path that starts with Gutenberg’s use of moveable type to Malcom McLean’s invention of the shipping container, we start to recognize a very interesting pattern: Each new layer of abstraction and standardization creates value out of the resulting increases in scale and efficiency.
Today’s digital innovators can trace a similar historical path that starts with mainframe computers and monolithic applications and then, step-by-step, reveals software’s interchangeable parts until we arrive at today’s cloud-based era of microservices and continuous integration.
Microservices is an approach to building software that shifts away from large monolithic applications toward small, loosely coupled and composable autonomous pieces. The benefit of this abstraction is specialization, which drives down costs to develop and drives up agility and quality — while operating much more resilient systems.
