Microservices are an architectural approach in which a single application is composed of many loosely coupled and independently deployable smaller components, or services. Characteristic of microservices : - Code can be updated more easily - new features or functionality can be added without touching the entire application. - Teams can use different stacks and different programming languages for different components. - Components can be scaled independently of one another, reducing the waste and cost associated with having to scale entire applications because a single feature might be facing too much load.
