"Introduction to DevOps: Transforming and Improving Operations” aims to help you develop a good working knowledge of the concept of DevOps, covering the foundation, principles, and practices of DevOps. This course will focus on the successful patterns used by high performance organizations over the past 10 years.

The core structure of this course is organized around the three basic principles of DevOps, otherwise known as the “Three Ways”. The “Three Ways” outline the values and philosophies that guide DevOps processes and practices:

• The First Way - This is a set of principles and practices that accelerate the delivery of IT services. Much of the material covered in this section will focus on Continuous Delivery and the extended principles and practices that lead to an accelerated flow.
• The Second Way - This is a set of principles and practices that amplify feedback loops.  In this section we will cover the concepts of creating a problem solving culture, as well as understanding monitoring, as it applies to DevOps. A significant portion of this section will also include monitoring business metrics, and will also explain how change management applies to DevOps.
• The Third Way - The patterns discussed in this section cover the concepts of organizational learning and safety culture. Items like blameless postmortems, resilience engineering, and systems thinking as they apply to DevOps will be covered in this course.

The goal of this course is to cover an extensive study of all of the DevOps principles and practices known to date, such that you can create transformative DevOps initiatives with incredible outcomes. This course also sets up the foundation for implementing the tools and technology that will be needed for further success and execution of a DevOps transformation. 

If you are a manager or a practitioner looking for guidelines on how to start transforming organizations, this course is for you. Upon completion, you should have a good understanding of the foundation, principles, and practices of DevOps. You should be able to continue your progress for an organizational transformation using the acquired skills set.

Now that you’ve mastered the basics, the Intermediate level is where C++ truly shines.

This course is the second in a three-part series designed to teach students some of the most important C++ concepts. This part focuses on how C++ interacts with memory, featuring concepts like pointers/memory addresses, heap memory management, and writing/reading files.

Knowing C++, you can create applications that will run on a wide variety of hardware platforms such as personal computers running Windows, Linux, UNIX, and Mac OS X, as well as small form factor hardware such as IoT devices like the Raspberry PI and Arduino –based boards.

Many health complaints, such as cardiovascular disease, diabetes or joint problems seem inescapable diseases of old-age, but originate mostly from our lifestyle. A lifestyle that is largely dictated by our environment. The mismatch between our 'old' genes - our evolutionary heritage - and the 'modern' environment is the reason that we cannot resist the constant stimuli that seduce us to make unhealthy choices. Do's and don'ts cannot help us. 

This health course will take a radically different approach to showing you how to secure a lifestyle, which will keep you healthy throughout the lifespan. We have to let the environment do the work for us. By making small changes at our home, work, school or neighbourhood, healthier choices can become easier and automated.

Practical assignments will give you the skills to re-design your daily environments to promote healthy, longer lives for you and your family, colleagues and neighbours with whom you share your re-designed environments. You will learn how to create your own healthy living zone!

We will take you on excursions to Copenhagen, Denmark and to Ghent, Belgium to show you hands-on how the environment can help you live longer, healthier and happier lives!

Living cells have unique functions that can be harnessed by engineers to tackle human problems in energy, water, food, and health.

Historically living cells were considered too difficult to predictably engineer because of their complexity, vulnerability, and continuous change in state. The elucidation of the design principles that underlie cell function along with increasing numbers of examples of hybrid cell based devices are slowly erasing that notion.

In this class you will be learn about these established and emerging cellular design principles and begin to view cells as machines. This knowledge can also then be applied to non-living devices that mimic and communicate with cells. You will also be introduced to current and emerging living/non-living biohybrid devices such as biohybrid robots and neural implants.

This course is part of the Microsoft Professional Program Certificate in Big Data, and the Microsoft Professional Program Certificate in Data Science. 

The open-source programming language R has for a long time been popular (particularly in academia) for data processing and statistical analysis. Among R's strengths are that it's a succinct programming language and has an extensive repository of third party libraries for performing all kinds of analyses. Together, these two features make it possible for a data scientist to very quickly go from raw data to summaries, charts, and even full-blown reports. However, one deficiency with R is that traditionally it uses a lot of memory, both because it needs to load a copy of the data in its entirety as a data.frame object, and also because processing the data often involves making further copies (sometimes referred to as copy-on-modify). This is one of the reasons R has been more reluctantly received by industry compared to academia.

The main component of Microsoft R Server (MRS) is the RevoScaleR package, which is an R library that offers a set of functionalities for processing large datasets without having to load them all at once in the memory. RevoScaleR offers a rich set of distributed statistical and machine learning algorithms, which get added to over time. Finally, RevoScaleR also offers a mechanism by which we can take code that we developed on our laptop and deploy it on a remote server such as SQL Server or Spark (where the infrastructure is very different under the hood), with minimal effort.

In this course, we will show you how to use MRS to run an analysis on a large dataset and provide some examples of how to deploy it on a Spark cluster or a SQL Server database. Upon completion, you will know how to use R for big-data problems.

Since RevoScaleR is an R package, we assume that the course participants are familiar with R. A solid understanding of R data structures (vectors, matrices, lists, data frames, environments) is required. For example, students should be able to confidently tell the difference between a list and a data frame, or what each object is generally a good representation for and how to subset it. Students should be familiar with basic programming concepts such as control flows, loops, functions and scope. Students should have a good understanding of how to write and debug R functions. Finally, students are expected to have a good understanding of data manipulation and data processing in R (e.g. functions such as merge, transform, subset, cbind, rbind, lapply, apply). Familiarity with 3rd party packages such as dplyr is also helpful.
