What term best describes a set of loosely coupled, fine-grained services that communicate via lightweight protocols, allowing organizations to easily build new services without additional dependencies or infrastructure?

Microservices are loosely coupled and fine-grained, and they are intended to be easy to deploy without significant overhead or dependencies. They rely on lightweight protocols like HTTP to make them easier to deploy in common infrastructures. Containers are used to allow applications to be easily deployed without moving a complete operating system but with the required libraries and components to function. The Internet of Things (IoT) describes Internet-enabled devices of all sorts, including embedded systems. Software-defined infrastructure is commonly used for cloud services.
