Welcome to my home at the University of Chicago. I lead the customer team for Globus and teach in the Masters Program in Computer Science. I am also an advisor to early stage software companies in the areas of go-to-market strategy, product management, and marketing.
Cloud computing is being widely adopted by enterprises of all sizes due to the low initial investment required, attractive operating costs, and elastic capacity that can best serve the highly variable demands of modern applications. Software engineers must be familiar with cloud computing technologies since many new applications they develop will be deployed “in the cloud”, and existing applications will often require integration with cloud-hosted services to take advantage of new capabilities.
This course provides an introduction to cloud computing with specific consideration for application development in two contexts: highly scalable (or so-called “web-scale”) web applications, and enterprise applications in a hybrid environment comprising both on-premises and cloud infrastructure. We will focus primarily on infrastructure and platform services, and will introduce software-as-a-service from the perspective of a consuming application. The course will emphasize practical applications of cloud computing technologies, with sufficient exploration of their theoretical underpinnings to inform architectural, design, and implementation decisions. We will use commercial cloud offerings provided by Amazon Web Services to build and deploy "real” cloud-hosted applications.
Topics covered include:
During the first six weeks of the course, a series of short programming assignments will be due each week. During the last four weeks we will work towards a capstone project that brings together many of the concepts and technologies covered in the course. Some of the earlier programming assignments will provide components to be used in our capstone project so it is important to stay current on coursework, otherwise you may find completion of the capstone project very challenging.
The grade for this course will be heavily weighted towards the capstone project. There will also be two short quizzes covering material that you should be familiar with if you have attended class and completed the programming assignments.
There is no formal textbook for this course. We will refer to a variety of online resources, including selected readings on cloud concepts, programming guides for Amazon Web Services, and references for various technologies used in programming assignments.
This course assumes no prior knowledge of cloud computing. Programming assignments require familiarity with Python and use of Linux commands, as well as simple shell scripts. We will use the boto library to access Amazon Web Services, and some assignments, including the capstone project, will make use of Flask, a Python-based micro-framework for web applications. A brief overview of boto, the web framework, as well as a list of reference materials will be provided; additional concepts will be introduced as they are needed to complete assignments. Knowledge of web application development is not required, but students with little or no web development experience may find some assignments particularly challenging. Ideally, students should understand the fundamentals of web APIs in general, and the REST approach in particular. An understanding of database concepts, such as referential integrity and ACID properties, is also useful.
Note: Students in past courses have struggled to keep up with homework assignments due to limited experience with Python and knowledge of the Linux command line. See the notes on this page for more detail on expected knowledge—if you have doubts about your proficiency in these areas please talk with me before signing up for the course.
Product management is a cross-disciplinary endeavor that sits at the intrersection of software engineering, marketing, and the user experience. Product managers are expected to create products in support of business objectives, ensuring that products deliver value to customers and are feasible to build within varying sets of constraints. In this course we will introduce the role of the product manager and demonstrate the challenges faced by product managers. We will explore approaches for managing the tension that exists between software development and product delivery, using the minimum viable product and the product roadmap as critical tools. Key themes covered in this course include:
This course incorporates a mix of case studies, in-class exercises, product design sessions, written work, and presentations. A key element of product management is communication, so there is an expectation that every student will contribute regularly to class discussions. You will work in small groups during class, rapidly developing new concepts and ideas which you will then present to the rest of the class. Unlike many other courses in the MPCS, you will be called upon to challenge the ideas presented by your fellow students—in a constructive manner, of course!
The grade for this course is split roughly evenly between homework assignments, quizzes, and in-class activities. Note that overall class participation will be a substantial component of the final grade.
While there is no prescribed reading for this course, we will review the approaches developed by Geoffrey Moore, as presented in his classic book "Crossing the Chasm", so feel free to get yourself a copy if you want to dive deeper into some of the concepts.
This course assumes no prior knowledge of product management concepts or specific technologies. However, you may find some of the material easier to put into perspective if you're familiar with software design patterns, or have taken one of the other software engineering courses offered in the MPCS.
Globus (www.globus.org) is software- and platform-as-a-service for research data management, developed and operated by the University of Chicago. The service offers a suite of data and user management capabilities to the research community, encompassing file transfer and sharing, identity management, and data publication. Globus capabilities are accessible via both a web browser and REST APIs. Web access allows Globus to address the needs of research labs through a software-as-a-service (SaaS) model, while REST APIs address the needs of developers of research services, who can use Globus as a platform to simplify access via data portals, science gateways, and other web applications.
Globus is currently used by all R1 research institutions in the USA, many national laboratories, federal facilities, as well as hundreds of non-profit and commercial organizations around the world. Researchers have transferred hundreds of petabytes and shared billions of files using Globus since the service was first deployed in November 2010.
File Transfer: Using Globus, researchers can coordinate high-performance, secure, file transfer and synchronization between storage systems. The service significantly simplifies large scale data transfer by handling all the difficult aspects of moving files across diverse and sometimes unreliable networks. For example, it coordinates authentication at source and destination, automatically tunes parameters to maximize bandwidth usage, provides automatic fault recovery, and notifies users of completion and problems.
Data Sharing: While researchers typically have access to considerable storage resources, it is often difficult to grant their collaborators access to those resources, due to cost, technical infeasibility, or restrictive administrative policies. Globus data sharing is designed to specifically fill this gap, providing the ability for users to dynamically share data with others without having to copy the data to the cloud, and without the need to provision temporary accounts on local storage systems.
Data Publication: Researchers and funding agencies alike are increasingly concerned with scientific reproducibility. To this end, Globus provides a self-service data publication service that can support arbitrarily large datasets. Globus data publication can be used both as a "turnkey" service and as a set of data management functions integrated into existing institutional repositories and custom, data distribution systems. The service greatly simplifies the assembly, annotation, curation, publication, and discovery of diverse datasets, governed by a series of user- or institution-defined policies.
The capabilities described above are primarily designed to address the needs of individual researchers directly; however, they are equally valuable to those developing their own scientific services, many of whom have little desire to build and operate their own authentication, data access, and data transfer infrastructure. The Globus platform addresses the needs of this developer community by exposing all Globus capabilities via REST APIs, and providing software developer kits and code samples to simplify integration of the various features into their own applications. Check out these resources to see how Globus can help you build more widely accessible research applications faster:
