Infrastructure is a term that encompasses all of the basic systems that businesses, communities, or entire states and countries rely on for their regular functioning. Traditionally, infrastructure refers to physical systems such as transportation networks, water pipes and sewage treatment facilities, and the electricity grid. This type of infrastructure is fundamentally important for living our lives in the modern world, and the design and maintenance of these systems is a central concern of city planning.

In recent years, infrastructure has also come to mean the computing systems and network architecture that organizations of all kinds rely on for their information technology (IT) needs. IT infrastructure used to consist mostly of on-premise system components and hardware like computers, servers, and local area networks (LANs). However, today’s IT systems increasingly rely on cloud computing infrastructure to provide scalable and secure services such as data storage and compute resources.

If you want to help guide the development of the physical infrastructure systems that are essential to our daily lives, there are several career paths you can consider. Civil engineering careers are an opportunity to oversee the design and construction of infrastructure such as bridges, dams, and power plants. If you want to work on the business side of developing these projects and making sure they are economically sustainable, you may study project finance. And, if your interest is in determining which kinds of infrastructure systems are needed and where to build them, you should look into a career in city planning.

On the other hand, if your interest is in information technology (IT) infrastructure systems, you can pursue a career in system administration. These important personnel are responsible for the design, installation, cybersecurity, and day-to-day operation of the IT systems that organizations rely on, from on-premise intranets to cloud-based resources. According to the Bureau of Labor Statistics, network and system administrators earn a median annual salary of $83,510, and typically have at least a bachelor’s degree in computer science.

Yes! Regardless of whether your interest is in the physical infrastructure systems that are essential to modern life or the IT infrastructure that is nearly as essential to the modern workplace, Coursera offers courses and Specializations spanning multiple courses to fit your needs. You can learn about physical infrastructure design, finance, and even emerging “smart city” systems from world-class universities like Università Bocconi and École Polytechnique Fédérale de Lausanne or from leading engineering software company Autodesk.

Similarly, if your interest is in IT infrastructure, you can learn from top-ranked schools like University of Minnesota, New York University, and University of Illinois at Urbana-Champaign, or from leading IT service and cloud computing providers like Google Cloud. No matter how you choose to learn, Coursera lets you view course materials and complete assignments on a flexible schedule so that you can build these valuable infrastructure skills while continuing your existing work, family, or school life.
