What is iPlant?"
•  iPlantʼs mission is to build the CI to support plant
biologyʼs Grand Challenge solutions"
•  Grand Challenges were not defined in advance, but
identified through engagement with the community"
•  A virtual organization with Grand Challenge teams
relying on national cyberinfrastructure "
•  Long term focus on sustainable food supply,
climate change, biofuels, ecological stability, etc"
•  Hundreds of participants globally… Working group
members at >50 US institutions, USDA, DOE, etc."
Brief History"
•  Formally approved by National Science Board – 12/2007"
•  Funding by NSF – February 1st, 2008 "
•  iPlant Kickoff Conference at CSHL – April 2008"
o  ~200 participants"
  Grand Challenge Workshops – Sept-Dec 2008"

  Project Recommendations – March 2009"
  Project Kickoffs – May 2009 & August 2009"
  First Release of Discovery Environments – April 2010"
The paradigm shi-   Classic paradigm: You produce data, analyze, interpret (end to end)   Conven=onal paradigm: Consor=um/centers produce data and you consume it   New Paradigm: Consor=um/centers have produced data and crea=ng “cyber infrastructure” to tackle the “grand challenge” GC Projects Recommended by the
iPlant Board of Directors March 2009

What is Cyberinfrastructure?
(Originally about TeraGrid)"
WWW.TERAGRID.ORG
It was six men of Indostan,
To learning much inclined,
Who went to see the elephant,
(Though all of them were blind),
That each by observation
Might satisfy his mind.
It’s a
Grid!
It’s a
Network!
They are
HPC
Centers!
It’s a
Common
Software
Environ!
And More!:
- Viz
- Facilities
- Data
collections
It’s Apps
and
Support!
It’s
Storage!

can grow through community contribution!
Open Source Philosophy, Commercial Quality Process"
•  iPlant is open in every sense of the word:"
–  Open access to source"
–  Open API to build a community of contributors"
–  Open standards adopted wherever possible"
–  Open access to data (where users so choose). "
•  iPlant code design, implementation, and
quality control will be based in best industrial
practice"
Portfolio of Activities"
•  Maintaining a balance of “past, present, future”
strategies"
–  “Past”: make services, systems, and support
available to existing bioinformatics projects, either to
enhance them or simply make critical tools more
widely available. "
–  “Present” build the best bioinformatics software tools
that todayʼs technologies can provide. "
–  “Future” track emerging technologies, and where
appropriate stimulate research into the creation and
use of those technologies. "
Portfolio of Activities"
•  In a nutshell:"
–  12 Working groups in the two grand challenges, each of
which is defining requirements for DE development. "
Each group not only has discussions that leads to final projects, but they also
spawn prototyping efforts, tech eval projects, tool support projects, etc. "
–  Services group: provide cycles, storage, hosting, etc. to
users. "
–  A comprehensive technology evaluation program to find,
borrow, or build relevant technologies, headlined by the
semantic web effort."
–  A number of ancillary projects related to grand challenges,
i.e. APWEB, high throughput image analysis "
–  The Core development/integration effort. "
Systems and Services"
•  Provide access for problems like these on
large scale systems"
•  Provide the storage infrastructure for
biological data (again, in support of
existing projects)"
•  Provide cloud style VM infrastructure for
service hosting. "

offering “cloud”
style hosting
services."
•  Dynamically launch
virtual servers
hosted by iPlant."
•  Still in prototype "
Arrival of “As a Service” models
Cyberinfrastructure Is “Research as a Service” SaaS: So;ware as a Service (e.g. Clustering/Assembly is a service) PaaS: PlaIorm as a Service IaaS plus core so;ware capabiliEes on which you build SaaS (e.g. Hadoop/MapReduce is a PlaIorm) IaaS: Infrastructure as a Service (get computer Eme with a credit card and with a Web interface like EC2) 22
