Your manual to the modern cloud computing network

Making networks work quickly and securely in the modern cloud age is not easy. Here's what you must know to fashion a fast-moving, cloud-connected enterprise network today.


How does cloud computing affect the network? A short question, but the answers are many and varied. This collection examines the subject of cloud computing networks from many angles, from the basics of terminology to the latest advances, like software-defined networking. If your enterprise is considering the cloud, or already there, this guide is essential for you.


The basics of cloud and the network

To fashion a secure network in the cloud era, it is important to get the basics under your belt. This section offers an overview of cloud history, covers the basics of a cloud-computing architecture, and looks at key issues like visibility, cloud types and more.
