  2. 2. Cloud Computing 101Subscribe to virtual computing resources hosted on the networkUser Benefits: – Pay as you go – No upfront capital outlay – No hardware maintenance – Illusion of infinite computing resources available on demand Enablers: – More powerful hardware resources for less (Moore’s Law) – Virtualization • Resource sharing • Multi-Tenancy – Excess Bandwidth (Dotcom Bubble) • Remote access • Distributed ComputingPublic Clouds: – Amazon (EC2, S3) – Rackspace – GooglePrivate Clouds: – VMWare VCloud – OpenStack © 2011 IBM Corporation

  11. 11. Inter-Cloud Mobility Empirical StudyIBM Israeli Evaluation – Haifa 100 – Tel Aviv KM – Conclusions • Time to migrate is function of rate or change and CoW size (not VM size) • Co-located VM network performance not adversely affected by migration I/O Access after migrated Migration 10 MB 100 MB 1 GB Method Shared 00.06s 15.00s 76.00s Storage Our Solution 00.03s 05.10s 15.00s © 2011 IBM Corporation

Cloud Federation Load Balancing Reservoir EU Project Federation – Thales, France – Umea University, Sweden – UNIME University, Italy Use case – Thales cloud deploys SAP but lacks resources – Migrates Sun Grid Engine VMs to UMEA Measurements – 30-60 second migration time – Inter-cloud network latency 55 milliseconds – 0.5 millisecond network latency co-located VMs 2000 KM 2600 KM 1600 KM © 2011 IBM Corporation
