Inter cloud-vm-mobility

  1. 1. Kenneth Nagin, David Hadas, Zvi Dubitzky, Alex Glikson, Irit Loy, BennyRochwerger, Liran SchourIBM Research Lab in Haifa (HRL)Inter-Cloud Mobility of VirtualMachines © 2010 IBM Corporation
  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
  3. 3. Cloud Insularity Cloud Federation Autonomy Cloud Burst Privacy Load balancing Security Global Utility Inter-Cloud VM Mobility Inter-Cloud Live VM Migration Internet Scale Virtual Application Network © 2011 IBM Corporation
  4. 4. Live VM migrationSame Cloud (state of the art) Between co-located hosts – Same subnet – Shared storageInter-Cloud (our contribution) Spans: – subnets – WAN – administrative boundaries Between – Anonymous hosts – Without shared storage Long Distance © 2011 IBM Corporation
  5. 5. Secure Inter-Cloud Migration Channel Source Cloud Internet Destination Cloud Migrate Tunnel Port Forwarder Memory State Storage Proxy Proxy Base Base CoW Migration with Non-Shared Storage Copy Modes Whole disk Copy on Write (CoW) – delta copy only Open source contributions QEMU-KVM 0.12.1 libvirt 0.8.2 © 2011 IBM Corporation
  6. 6. Virtual Application Networks (VANs) Fully isolated virtual application networks – Complex Application with multiple components, e.g. 3 tier – Supports multi-tenancy Host Based Solution with Dynamic Routing A Distributed Virtual Network Offers L2-like network services§ ¥ ¨ © ¦ ¤ £ £ ¤ ¥ ¤ ¦ ¥ ¦ £ § ¦ £ § © !

  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
  12. 12. 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
