Traditional monolithic architectures are difficult to scale and become too complex to update and maintain as an application's code base grows, which limits introducing new features, languages, frameworks, and technologies, thus stifling innovation and new ideas. By contrast, a microservices architecture comprises many individual application components, each running as its own single-function service, communicating with other services through a well-defined API, greatly enhancing scalability and ease of maintenance. In this workshop, we show you how to run a simple monolithic application in a Docker container, deploy the same application as microservices, and switch traffic to the microservices without downtime.

Microservices
“A software architecture style in which complex applications are composed of
small, independent processes communicating with each other using language-
agnostic APIs. These services are small, highly decoupled and focus on doing a
small task, facilitating a modular approach to system-building.” —Wikipedia

Containers and Docker
A container is a standard unit of software that packages up code and all its
dependencies so the application runs quickly and reliably from one computing
environment to another.1
