The idea of security perimeters has been seen as passé and insufficient for several years now, but the concept of a perimeter (or an Edge) is still useful in the design of large-scale delivery networks. The normal definition of an “Edge” is the point of ingress for users.
If we want to do initial processing on incoming traffic, it is most naturally done in the Edge, much as firewalls do in the traditional security perimeter. Apache Traffic Server is a caching web proxy that fulfills such a position in the Edge architectures of several companies that have large content delivery networks. In this talk, we will provide an overview of Apache Traffic Server. We will also describe how it can be used to support performance, reliability, and security in a corporate Edge environment, using the Yahoo! Edge as an example.
Alan M. Carroll became a professional programmer in 1977 and has since worked on a variety of large-scale software projects, such as Epoch, the first multi-X-windowing version of Emacs. He started working on Apache Traffic Server in 2010 and worked his way up to be a committer and then a member of the Apache Software Foundation. Alan is best known there for his work on proxy transparency, IPv6, and caching, and for an inappropriate fondness for C++ templates.
Alan earned a BS and a PhD in Computer Science at UIUC. After graduating, he joined a startup working on network security, which got acquired by Cisco Systems. He spent a number of years at Cisco working on policy-based network security management. He has recently joined the Yahoo! Edge team.
Susan Hinrichs recently joined the Yahoo! Edge team. She is a committer on the Apache Traffic Server Project. Before joining Yahoo!, Susan did consulting work with Network Geographics in the area of networks and security, working with firewall analysis, netfilter controls, and security analysis and design. She also spent eight years lecturing on computer security at the University of Illinois.
Susan earned a BS in Computer Science from the University of Illinois and a PhD from Carnegie Mellon University. After graduation, she joined a network security startup that was acquired by Cisco Systems. While at Cisco, Susan led efforts in policy-based security management and firewall analysis.
