3 3 The “Grand Challenge” Phase of Research Transition from individual experimenter to institution or multi-institution team Typically necessitated because problems go beyond the scale of an individual research group Investigation of new phenomena required dramatic resources Ex: particle physics 1928-1932

The information contained herein is subject to change without notice. 4 4 Experimental Physics Before 1928 Dominated by tabletop apparatus Ex: Rutherford’s discovery of the nucleus, 1910 Done with tabletop apparatus, shown here Major complication: had to observe in darkened room

© Copyright 2012 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice. 9 The era of institutional systems research Computer Systems Research, 1980-2010 Dominated by desktop-scale systems 1980-~1995: The desktop was the experimental system Ex: Original URL of Yahoo! was akebono.cs.stanford.edu/yahoo.html Akebono was Jerry Yang’s Sun workstation! Named for a prominent American Sumo wrestler – Jerry had spent a term in Kyoto in 1992 Sometimes “servers” used to offload desktops But rarely: “Server” ca. 1990 was a VAX 11, less powerful than a SUN or DEC workstation ~1995-~2005: Used servers primarily because desktop OS unsuitable for serious work ~2005-: Need clusters (and more) for any reasonable experiment The Era of Institutional Systems Research has begun 9
10
© Copyright 2012 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice. 10 Why? Activity in 21 st Century Systems Research focused on massively parallel, loosely-coupled, distributed computing Content Distribution Networks Key-Value Stores Cloud Resource Allocation and Management Wide-Area Redundant Stores Fault Recovery and Robust Protocols End-system multicast Multicast messaging Key Problem: Emergent Behavior at Scale Can’t anticipate phenomena at scale from small-scale behavior Hence: Moderate-to-large scale testbeds: G-Lab, PlanetLab, OneLab,… 10
11

The information contained herein is subject to change without notice. 11 11 Why Computer Science is undergoing a phase change Key: need to understand planetary-scale systems Systems and services that run all over the planet Critical, pervasive, robust Emergent behavior at scale Can only understand by experimenting near scale Require millions of simultaneous users (or at least simulations of that scale) Ex: Twitter crashed at 1m users (and needed to rebuild infrastructure) Requires planetary-scale testbed and deployment platform

The information contained herein is subject to change without notice. 12 12 Key Differences Apparatus now takes many years to construct, costs billions Requires multi-national consortia Discoveries made by large teams of scientists Hundreds on the Top Quark team\ Thousands on the Higgs Team Experiments last for 30+ years Ex: ALICE at LHC, Babar at SLAC Experimental devices measured by energies of collisions produced Driven by cost and complexity of apparatus Cockcroft and Walton heralded era of institutional Grand Challenge physics
13

The information contained herein is subject to change without notice. 13 Problem: We can’t Build it 13 Industrial scale is rapidly outstripping academic/research scale Ex:Yahoo! “Clique” is 20,000 servers 20 VMs/server 400,000 VMs Far beyond any existing testbed PlanetLab + OneLab: 1000+ nodes Emulab: ~500 nodes Glab… Single Yahoo Clique 20x our best testbeds So what do we do? Federation…
14
© Copyright 2012 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice. 14 Why Federate? 14 Because we can each afford a piece… Federate a large number of small clouds and testbeds Agree on common APIs and form of authorization Ad-hoc federation
15
© Copyright 2012 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice. 15 InstaGENI and GENICloud/TransCloud Two complementary elements of Federation Architecture Inspiration: the Web Can we do for Clouds what the web did for computation? Make it easy, safe, cheap for people to build small Clouds Make it easy, safe, cheap for people to run Cloud jobs at many different sites GENICloud/TransCloud Common API across Cloud Systems Access Control without identity Equivalent of http InstaGENI “Just works” out of the box small cloud “Apple II”/reference webserver of Clouds
16

The information contained herein is subject to change without notice. 16 Key Assumption Each facility implements Slice-Based Facility Interface Standard, unified means of allocating Virtual machines at each layer of the stack (“slivers”) Networks/sets of virtual machines (“slices”) Already supported by PlanetLab, ORCA, ProtoGENI Now supported by Eucalyptus and OpenStack (our contribution) 16
17
© Copyright 2012 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice. 17 What we need, what we don’t What we need Method of creating slices on clouds and distributed infrastructures Method of communicating between clouds and distributed infrastructures Method of interslice communication between clouds What we don’t Single sign-on! Single AUP Single resource allocation policy or procedure Unified security policy Principle of Minimal Agreement What is the minimum set of standards we can agree on to make this happen? 17
18
© Copyright 2012 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice. 18 What do we need from the clouds Building Blocks Eucalyptus: Open-source clone of EC-2 OpenStack: Open-source Widespread developer mindshare (easy to use, familiar) What we want: Slice-Based Federation Architecture Means of creating/allocating slices Authorization by Attribute-Based Access Control (ABAC) Delegation primitive Explicit costs/resource allocation primitives Need to be able to control costs for the developer 18
19
© Copyright 2012 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice. 19 Why GENICloud? Minimal set of facilities to permit seamless interconnection without trust Motivation: the Web Web sites mutually untrusting Key facilities: DNS, HTTP. HTML What are the equivalents for Clouds? Our cut: Slices, ABAC, DNS conventions....transcloud.net 19

The information contained herein is subject to change without notice. 21 Seamless Computation Services Available Anytime, Anywhere “The Cloud” offers the prospect of ubiquitous information and services…BUT… Performance of Cloud services Highly Dependent On Location Of End-User, Applications, Middle Processes, Network Topology Of Cloud Data, Compute Processes, Storage, etc Why? Performance of Legacy Protocols Highly Dependent on Latency Therefore: Want to compute anywhere convenient Want to be able to compute everywhere
22
© Copyright 2012 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice. 22 What do we need to make this work? Advanced Networking and Caching Firm guarantees on bandwidth and latency on a per-application basis Application support at Layer 3 and Layer 2 Means: Private Network where possible Access to platforms wherever data lives But data lives everywhere! No organization has Points of Presence (PoP)s everywhere Need for an individual to be able to make arrangements with an cloud service provider, anywhere, efficiently, minimal overhead Common form of identity Common identity not required Common AUP not required
23
© Copyright 2012 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice. 23 What do we need to make this work? Ability to instantiate and run a program anywhere Common API at each level of the stack IaaS/NaaS (VM/VN Creation) PaaS (guaranteed OS/Progamming environment) OaaS (Standard Query/Data Management API) Easy, Standard Naming Scheme I need to know the name of my VM’s, logins, store etc without asking
