Visualizing Clouds

At Cydar, we make extensive use of Amazon Web Services. In particular, we use their Virtual Private Cloud (VPC) features to set up many separate virtual networks, each containing a number of virtual machine running different software for different purposes. The connections both within and between these networks quickly become complicated. Moreover, as we’re dealing with highly confidential patient data, we need to be sure we have a good understanding of how the network is configured and where the data is going at all times.

The brief is to create a tool for visualizing VPCs in some kind of automated block diagram. It should show, at a minimum: - Connections between machines within a VPC - Routes in and out of each VPC (as governed by AWS Security Groups)

The visualization should update automatically as the network changes. Once the basics are in place, there’s plenty of scope for additional information such as: - Real time network traffic display - Server health monitoring - Interaction, for example to focus on more details of a particular VPC

Cydar will be able to provide technical help in integrating with AWS, as well as example networks to visualize.
