Course Learning Outcomes

Computational Practice

Students will learn the following computational practices:

  1. Students can implement programming projects that display knowledge of a variety of distributed system architectural styles. Assignments include significant programming projects with wide leeway in design and implementation choices.
  2. Students will analyze problems, determine solutions within an assigned architectural style, and successfully implement those solutions.
  3. Students will design and implement projects both individually and as part of a team.
  4. Students will use cloud-based systems to run and implement assignments.
  5. Students will manage a cloud-based web server and properly configure it.

Computational Theory

Students will understand the proper use of distributed and decentralized architectures and algorithms including

  1. RESTful APIs
  2. Hierarchical vs heterarchical system architectures
  3. Parallel computing and MapReduce
  4. Event-driven and reactive systems
  5. Peer-to-peer systems
  6. Uses for algorithms including Distributed Hash Tables (DHT), Paxos, gossip protocols, and blockchain

Students will understand theoretical concepts and limitations of distributed systems including

  1. network practicalities such as latency, bandwidth, topology, cost, heterogeneity, security
  2. coupling
  3. consensus
  4. CAP theorem
  5. distributed transactions
  6. serialization
  7. identity and naming
  8. cryptography
  9. simultaneity

Critical Thinking and Communication

Students will engage in meaningful discussion, prepare written reports, and make presentations.

Ethics and Computing

Students will be presented with societal outcomes of technological choices in distributed and decentralized systems, analyze those outcomes, explore possible alternatives from different choices, and present their findings in small groups .


Software Design (CS 340) or equivalent experience.

Internet Application Programming (CS 360) or equivalent experience.

Course Organization

Each lesson (except the first) includes a reading quiz comprising some number of multiple-choice, matching, fill-in-the-blank, and true-false questions. The best way to prepare for the quizzes is to complete the required reading in each lesson.

  1. Why Distributed Systems?
  2. Distributed System Architectural Patterns
  3. Integrity, Non-Repudiation, and Confidentiality
  4. Identity, Naming, and Directories
  5. APIs
  6. Parallel Architectures
  7. Failure and Consensus
  8. Peer-to-Peer Systems
  9. Reactive Systems and the Actor Model
  10. Microservices


Lesson Quizzes

Each lesson after lesson 1 concludes with a multiple-choice quiz over the basic concepts.

Lab Assignments

Lab assignments give you an opportunity to demonstrate your knowledge of how to apply course concepts in solving problems that call for distributed or decentralized solutions.

Most labs allow you to use any operating system and programming language you are familiar with.

Other Assignments

You will complete these assignments in conjunction with specific lessons.

Final Project

The final project is a free-form exercise to build a non-hierarchical distributed solution to a problem of your choice according to a set of instructor-provided constraints. You will complete three elements for the project:

(Back to top)


There is one final exam with two parts:

The exam questions ask you to apply principles from the course to analyzing distributed systems and solving problems related to distributed system design. The final exam is design oriented, and you will be required to make architectural and implementation decisions about proposed systems. The exam is closed book and notes, with a 90-minute time limit.

The quizzes, labs, and course project are your best guide in preparing for this work. If you don't participate fully in the assignments and the project, don't expect to do well on the exam.

Note: You must pass the final exam to earn credit for the course.

University Policy - Title IX Statement

Preventing & Responding to Sexual Misconduct

In accordance with Title IX of the Education Amendments of 1972, Brigham Young University prohibits unlawful sex discrimination against any participant in its education programs or activities. The university also prohibits sexual harassment—including sexual violence—committed by or against students, university employees, and visitors to campus. As outlined in university policy, sexual harassment, dating violence, domestic violence, sexual assault, and stalking are considered forms of "Sexual Misconduct" prohibited by the university.

University policy requires all university employees in a teaching, managerial, or supervisory role to report all incidents of Sexual Misconduct that come to their attention in any way, including but not limited to face-to-face conversations, a written class assignment or paper, class discussion, email, text, or social media post. Incidents of Sexual Misconduct should be reported to the Title IX Coordinator at t9coordinator@byu.edu or (801) 422-8692. Reports may also be submitted through EthicsPoint at https://titleix.byu.edu/report or 1-888-238-1062 (24-hours a day).

BYU offers confidential resources for those affected by Sexual Misconduct, including the university’s Victim Advocate, as well as a number of non-confidential resources and services that may be helpful. Additional information about Title IX, the university’s Sexual Misconduct Policy, reporting requirements, and resources can be found at http://titleix.byu.edu or by contacting the university’s Title IX Coordinator.
