Week 1

We will start by looking at the applications running in data centers and the traffic patterns resulting from them. This will help us differentiate the networking needs within data centers from computer networking in general and set the stage for other material in the course. We’ll then dive into the first of these topics, physical network structure, where we will look at how the increasing demand for bandwidth within data centers is influencing the network’s design.

Week 2

This week, we will dive further into the data center network stack, looking at routing and switching for physical and virtual machines and congestion control. We’ll examine what concerns routing needs to address in these environments and how it’s done in practice. We’ll also see how the network is moving deeper into the physical hosts in order to address the networking needs of virtual machines. With regards to congestion control, we’ll learn what problems TCP’s congestion control faces in data centers and how these are being addressed.

Week 3

This week focuses on management and sharing of network infrastructure in cloud data centers. Traditional networking technologies require complex, error-prone network configuration, and make sharing of the network across multiple tenants in a secure manner difficult. We’ll learn how software-defined networking and network virtualization are addressing these problems.

Week 4

Zooming out from within data centers, this week will examine other pieces of the cloud networking ecosystem: inter-data center WAN connectivity, content distribution networks, end-user Internet connectivity, and application interactions with the network. We’ll learn what novel techniques in each of these areas are pushing the cloud’s capabilities farther.

Top reviews from Cloud Networking

By BMNov 29th 2016

A phenomenal course on the challenges and solutions of today's Cloud infrastructures. The material is high quality and sourced from the best in the world. I'm extremely satisfied.

By SRApr 27th 2017

Best course ever! Very well-thought-about content. Requires you to go beyond just the videos and assignments. Far far better that course 3 & 4 of Cloud Specialization.
