CS *891: Scalable Microservices

Douglas C. Schmidt

d.schmidt@vanderbilt.edu

Professor of Computer Science

School of Engineering

Vanderbilt University

Times and Location

Classroom -- Monday and Wednesday from 8:40-9:55am in the Engineering Science Building room 48.
Final exam time will be discussed in class.

Philosophy

Developing high quality Java concurrent and parallel microservices is hard; developing high quality reusable concurrent and parallel microservices is even harder. The principles, methods, and skills required to develop reusable microservices cannot be learned by generalities. This course therefore teaches students how reusable concurrent and parallel microservices can be designed, implemented, optimized, validated, maintained, and enhanced by applying effective object-oriented, functional, and reactive development practices, patterns, and frameworks.

Prerequisites

Proficiency in Java, i.e., as covered in CS 1101
Proficiency in software patterns, i.e., as covered in CS 3251
Knowledge of email, the Web, and online discussion forums
Awareness of--and adherence to--the Vanderbilt University Honor Code that governs all work in this course (e.g. tests, quizzes, homework assignments, etc.), which must be done individually and in a "closed-book" manner (i.e., no outside help, no notes, no Internet, etc.)
