2014 docker boston fig for developing microservices
The document discusses developing microservices using Fig, an open-source tool for defining and running multi-container Docker applications. It summarizes Martin Fowler's definition of microservices as independently deployable services that communicate via lightweight mechanisms like HTTP. The document then demonstrates using Fig to run different programming languages and databases in isolated containers on a local machine for continuous and reproducible development of a microservices architecture.
