  2. 2. Adventures in Virtualisation: The Hosting Industry Aidan Finn Windows Server 2008 User Group: http://ws-ugi.spaces.live.com My Blog: http://joeelway.spaces.live.com
  3. 3. Agenda <ul><li>My background </li></ul><ul><li>Challenges and Opportunities in hosting </li></ul><ul><li>Virtualisation in the Hosting Industry </li></ul>
  4. 4. My Background <ul><li>Working in IT since 1996. </li></ul><ul><li>Worked in all sorts of large infrastructures. </li></ul><ul><li>Started doing things “my way” in 2003. </li></ul><ul><li>Working in hosting industry for 12 months. Now employed by C Infinity. </li></ul><ul><li>Working with Windows Server 2008 since last year. </li></ul>
  5. 5. Oh! <ul><li>I am slightly biased towards Microsoft-based solutions  </li></ul><ul><li>I’m more familiar with HP hardware and terminology ... IBM tends to have similar solutions. </li></ul>
  6. 6. Hosting – What is it? <ul><li>3 Categories: </li></ul><ul><ul><ul><ul><li>Website/Email hosting </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Co-Location </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Server hosting/outsourcing </li></ul></ul></ul></ul><ul><li>Motivations of customer: </li></ul><ul><ul><ul><ul><li>Security </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Reduce cost of ownership </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Avail of high quality bandwidth </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Budgeting </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Remote disaster recovery </li></ul></ul></ul></ul>
  7. 7. Hosting – What is it? <ul><li>Types of installation? </li></ul><ul><ul><ul><ul><li>100% server outsourcing </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Web applications </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Intranet applications </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Disaster recovery </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Virtual Desktops </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Terminal Server applications </li></ul></ul></ul></ul>
  8. 8. Hosting – What is it? <ul><li>Types of administration outsourcing? </li></ul><ul><ul><ul><ul><li>100% outsourced. </li></ul></ul></ul></ul><ul><ul><ul><ul><li>0% outsourced: co-location. </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Operating system and hardware. * </li></ul></ul></ul></ul>
  9. 9. Hosting – The Challenges <ul><li>Space </li></ul><ul><li>Power </li></ul><ul><li>More machines, more management, less staff </li></ul><ul><li>Service Level Agreements </li></ul><ul><li>Flexibility </li></ul><ul><li>Disaster Recovery </li></ul><ul><li>Business sense: Realistic technology and budget </li></ul>
  10. 10. Hosting – The Solution? <ul><li>Everyone’s talking about blade servers and virtualisation. </li></ul><ul><li>“ Cloud Computing” </li></ul>
  11. 11. Cloud Computing <ul><li>My Definition: </li></ul><ul><li>A fabric or matrix of technologies. </li></ul><ul><li>Utilise the correct technologies for each service. </li></ul><ul><li>Fault tolerant, agile and scalable. </li></ul><ul><li>Well managed with automation – often forgotten. </li></ul>
  12. 12. Virtualisation/Redundancy At Every Level <ul><li>Firewalls: Clustered. </li></ul><ul><li>Core Switches: Redundant. </li></ul><ul><li>Machines: Virtualisation available. </li></ul><ul><li>Server Hardware: Redundant. </li></ul><ul><li>Storage/Network Connections: Abstracted and redundant. </li></ul><ul><li>Storage: Virtualised and redundant. </li></ul>
  13. 13. Machine Virtualisation & Hosting <ul><li>Less hardware </li></ul><ul><li>Less power consumption </li></ul><ul><li>Rapid deployment </li></ul><ul><li>Mobility of machines </li></ul><ul><li>Lower operating costs = more competitive = more profit </li></ul><ul><li>And it’s “Green Computing” </li></ul>
  14. 14. Pre-Virtualisation
  15. 15. Post-Virtualisation Dude, where’s my hardware gone?
  16. 16. Virtualise Every Machine? <ul><li>Nooooooooo! </li></ul>
  17. 17. Virtualise Every Machine? <ul><li>Domain Controllers? </li></ul><ul><li>I/O Intensive machines? </li></ul><ul><li>CPU Intensive machines? </li></ul><ul><li>Does your application have support? </li></ul>
  18. 18. Which Machine Virtualisation Solution? <ul><li>Two big players: Microsoft and VMware. </li></ul><ul><li>VMware ESX/VI: </li></ul><ul><li>Mature, relatively well known, trusted. Limited hardware, difficult to manage. </li></ul><ul><li>Microsoft Hyper-V: </li></ul><ul><li>Based on Windows, wide hardware coverage, easy to manage, heavily tested. New and will take time for market to trust it. </li></ul>
  19. 19. MS or VMware For Me? <ul><li>Important – think long term! : </li></ul><ul><li>Costs </li></ul><ul><li>Skills availability </li></ul><ul><li>Manageability </li></ul><ul><li>Will the vendor still be in this market in 5-7 years time? </li></ul><ul><li>I’d choose Microsoft Hyper-V. </li></ul>
  20. 20. A Cloud
  21. 21. Why Blade and SAN? <ul><li>Flexible storage </li></ul><ul><li>Denser CPU deployment </li></ul><ul><li>Less power consumption </li></ul><ul><li>There might be larger capital/installation costs. </li></ul><ul><li>Operating costs are lower. </li></ul>
  22. 22. Virtual Connections <ul><li>Abstracted MAC address </li></ul><ul><li>Abstracted World Wide Name </li></ul><ul><li>Diskless Servers </li></ul><ul><li>Servers => Replaceable Appliances </li></ul>

  24. 24. Virtualised Storage <ul><li>Why Virtualise Storage? </li></ul><ul><li>Quick to deploy </li></ul><ul><li>Quick to modify </li></ul>Traditional Disk Virtual Disk RAID Array -> LUN -> Partition Disk Group -> Virtual Disk (RAID) -> Partition
  25. 25. You’ve Got To Manage This! <ul><li>Microsoft System Center </li></ul><ul><ul><ul><ul><li>Operations Manager 2007 SP1 </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Configuration Manager 2007 SP1 (in testing) </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Virtual Machine Manager 2008 (in testing) </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Service Desk 2009, 2010 or 2011?  </li></ul></ul></ul></ul><ul><li>Cradle-to-Grave management </li></ul><ul><li>Integration </li></ul><ul><li>Customer visibility </li></ul><ul><li>Reduced administration – really! </li></ul>
