General Information

This course consists of a sequence of four hands-on project-intensive immersive modules aimed at giving students an in-depth experience in developing different layers of a Cloud computing infrastructure including software defined networks (SDN), system software, network function virtualization (NFV), and application development.

Each module (roughly 4-5 hours of lectures) is organized as discussion of the technical details pertaining to that topic (from selected readings from research papers and other online resources).

Each lecture has an associated student assessment component via a graded online quiz.

A supervised lab component complements the concepts discussed in the lecture.

For the supervised lab, the students are given instructions for the *hands-on workshop* involving development of code and experimentation using appropriate technologies (OpenFlow, Mininet, Maxinet, Azure Cloud, etc.) of the concepts presented in the lectures.

The supervised lab enables students to get started on the workshop in class and complete it before the lab meeting in the following week.

Course Goals and Learning Outcomes

The course is purpose-built to ensure that the students graduating from this course will have the necessary skillset to work at any level of the Cloud software ecosystem.

Each of the four modules will enhance the understanding of students on what goes on behind the scenes in a Cloud platform.

Each module has a capstone project that builds on the weekly hands-on workshops.


Module 1: Software Defined Networking

Lectures: Topic covered include basics of cloud computing, origin of software defined networking, evolution of data center networks, network virtualization, testing, debugging, and measurements of data center network traffic.

Workshops and project: In the SDN module, the learners are expected to design, implement, and thoroughly test an SDN for a distributed server to cater to a variety of services, from regular HTTP web pages to real-time applications such as sensor streaming and video players.


Module 2: Cloud System Software

Lectures: Topics covered include programming frameworks and their implementation issues in the Cloud, storage systems for the cloud, resource management, and virtualization technologies.

Workshops and project: In the system software module, the learners are expected to design, implement, and thoroughly test the distributed runtime system for the MapReduce programming model in C++.


Module 3: Network Function Virtualization (NFV)

Lectures: Topics covered include origin of network functions, middleboxes, developing virtual network functions, provisioning computational resources for multiple virtual network functions via Cloud technologies and orchestrating their deployment using SDN, offloading NFV workload to a managed cloud, as well as other developments in the telecommunications industry that makes offloading NFV workloads viable.

Workshops and project: In the NFV course, the learners implement a control plane for the orchestration of network function chains on a shared physical infrastructure providing interfaces for scaling NF chains in response to workload changes.


Module 4: Cloud Applications

Lectures: Topics include principles for developing scalable applications in the cloud; management of cloud application software to deal with upgrades, resiliency, and evolution; novel cloud applications; and emerging landscape of edge computing and multi-datacenter infrastructures.

Workshop and project: In the application development course, the learners are expected to define a large-scale application project drawn from different domains (eCommerce, digital health, critical infrastructure protection, emergency response, disaster recovery, etc.), and implement them demonstrating the use of Azure platform services, and the need for elastic deployment of the Azure server instances.

2.    All post-lecture auto-graded assessments have to be completed fully and on time.

Exceptions will be handled per institute rules.

3.    All the workshops and projects must be completed fully and on time. Exceptions will be handled per institute rules.


Excused absence from supervised labs:

  Institute guidelines will be adhered to for students to be excused from attending the supervised lab sessions: https://catalog.gatech.edu/rules/4/


Grading (letter grades)

1.    Students must complete the assessments (quizzes) associated with each lecture.

The assessment quizzes serve to ensure that the students have learned the lecture materials.

2.    Due to the continuous assessment of student learning through the quizzes there are no exams in the course.

Plus, the hands-on workshops and projects based on the lecture material serve to ensure the learning goals of the course.

3.    Students will be given guidelines on software engineering principles to be adhered in code development.

4.    Letter grades in the course: there are only two letter grades for your performance in the entire course: A or F. To earn an A in the course, you have to do the following:

a.    Complete the auto-graded post-lecture assessment quizzes (with 100% score - you can have any number of attempts).

b.    Complete all the weekly hands-on workshops and capstone projects and get an *Accept* stamp from the teaching team for each unit work.

Grading (Auditing Requirements)

The requirements for successfully completing an audit of this class are as follows:

1.    Attend 70% of all synchronous class sessions. Since you will not be working in teams or on workshops, you may drop after the group session is complete, watch class videos, or anything else related to the class during the remainder of the online session.

2.    You must watch all mandatory pre-recorded classroom lessons.

3.    You must attempt and submit all weekly quizzes on-time; it will enhance your learning if you achieve 100%, as per the requirement for letter grade students.

4.    You should not join a team and are not required to submit any workshops or projects.
