|[PLUG] [plug-announce] Wed July 3 - PLUG Central - "Linux on Mainframes: Past, present, and future" by Elizabeth J. Joseph (7pm at USP)|
------------------ PLEASE NOTE ------------------ If the doors to Griffith Hall are locked, USP security will let you into the building if you call them. Please see below in this message for full instructions. ------------------------------------------------- PLUG Central will be meeting on Wednesday, July 3 at USP in Philadelphia, beginning at 7pm. Directions to the meeting location at the University of the Sciences in Philadelphia can be found at the end of this email. This month, PLUG welcomes back Elizabeth J. Joseph. Lyz will be giving a talk entitled "Linux on Mainframes: Past, present, and future". The discourse around where to host your Linux-based infrastructure tends to center around whether you should use the cloud or your own on-premises x86 hardware, but mainframes are rarely discussed. In this talk we'll have a look at how VM technology that got its start in the 1970s allowed Linux to be run on the mainframe by a group of hobbyists in the late 1990s. Then on to how it was swiftly noticed by IBM and development continued for the polished product line of mainframes that exclusively run Linux (officially RHEL, SLE, and Ubuntu) today. For the security-conscious, encryption technology built into the processor and on additional PCIe cryptography cards is accessible in Linux on the mainframe with your standard OpenSSL libraries, allowing for end-to-end encryption of data at rest and in flight that doesn't burn all of your regular processor resources. Enterprise-grade hardware that also has built-in redundancy reduces the need for management of a fleet of x86 servers, and the entry level Linux-only mainframes today even fit into a 19" rack space in the datacenter. Looking at the future, it's likely that even more pervasive encryption and reductions power consumption will be high on the list of requirements, and running Linux on a mainframe can help with those too! The meeting will be held at our usual location: University of the Sciences in Philadelphia (USP) Griffith Hall (Room "C" or "A", look for the signs) 600 South 43rd Street Philadelphia, PA 19104-4495 USP is located in University City. Driving directions are available at http://www.phillylinux.org/locations/usp.html, or http://www.usip.edu/directions, both of which have an aerial view of the campus buildings. USP is also easily accessible by public transportation. For those attending PLUG Central, if you arrive and the doors are locked you can call UCS's public safety number at 215.895.1117 and they will radio personnel in the guard booth or someone else to unlock the door. If you are asked who is sponsoring the meeting you can say "Zhiwei Liu" in the Chemistry department. There will be an open Question & Answer session at 7PM, prior to the main presentation at 8PM. This is an open meeting; all are welcome and encouraged to attend. Usually, a number of members get together after the meeting at a nearby restaurant for food and perhaps a beer or two. Come join the camaraderie!
