Microservice Architecture While there is no precise deﬁnition of this architectural style, there are certain common characteristics around organization around business capability, automated deployment, intelligence in the endpoints, and decentralized control of languages and data.

Serverless Architecture It refer to applications that signiﬁcantly depend on third-party services (knows as Backend as a Service or "BaaS") or on custom code that's run in ephemeral containers (Function as a Service or "FaaS"), the best known vendor host of which currently is AWS Lambda. By using these ideas, and by moving much behavior to the front end, such architectures remove the need for the traditional 'always on' server system sitting behind an application. Depending on the circumstances, such systems can signiﬁcantly reduce operational cost and complexity at a cost of vendor dependencies and (at the moment) immaturity of supporting services.
