                  Agenda
• My background
• Challenges and Opportunities in hosting
• Virtualisation in the Hosting Industry
             My Background
• Working in IT since 1996.
• Worked in all sorts of large infrastructures.
• Started doing things “my way” in 2003.
• Working in hosting industry for 12 months.
  Now employed by C Infinity.
• Working with Windows Server 2008 since last
  year.
                     Oh!
• I am slightly biased towards Microsoft-based
  solutions 
• I’m more familiar with HP hardware and
  terminology ... IBM tends to have similar
  solutions.
            Hosting – What is it?
• 3 Categories:
        – Website/Email hosting
        – Co-Location
        – Server hosting/outsourcing


• Motivations of customer:
        –   Security
        –   Reduce cost of ownership
        –   Avail of high quality bandwidth
        –   Budgeting
        –   Remote disaster recovery
            Hosting – What is it?
• Types of installation?
        –   100% server outsourcing
        –   Web applications
        –   Intranet applications
        –   Disaster recovery
        –   Virtual Desktops
        –   Terminal Server applications
          Hosting – What is it?
• Types of administration outsourcing?
        – 100% outsourced.
        – 0% outsourced: co-location.
        – Operating system and hardware. *
        Hosting – The Challenges
•   Space
•   Power
•   More machines, more management, less staff
•   Service Level Agreements
•   Flexibility
•   Disaster Recovery
•   Business sense: Realistic technology and
    budget
    Hosting – The Solution?

Everyone’s talking about blade servers and
                virtualisation.

           “Cloud Computing”
            Cloud Computing
My Definition:
• A fabric or matrix of technologies.
• Utilise the correct technologies for each
  service.
• Fault tolerant, agile and scalable.
• Well managed with automation – often
  forgotten.
    Virtualisation/Redundancy At Every Level

• Firewalls: Clustered.
• Core Switches: Redundant.
• Machines: Virtualisation available.
• Server Hardware: Redundant.
• Storage/Network Connections: Abstracted and
  redundant.
• Storage: Virtualised and redundant.
    Machine Virtualisation & Hosting
• Less hardware
• Less power consumption
• Rapid deployment
• Mobility of machines
• Lower operating costs = more competitive =
  more profit
• And it’s “Green Computing”
Pre-Virtualisation
   Post-Virtualisation




Dude, where’s my hardware gone?
Virtualise Every Machine?




Nooooooooo!
           Virtualise Every Machine?

•   Domain Controllers?
•   I/O Intensive machines?
•   CPU Intensive machines?
•   Does your application have support?
  Which Machine Virtualisation Solution?

• Two big players: Microsoft and VMware.

VMware ESX/VI:
• Mature, relatively well known, trusted. Limited
  hardware, difficult to manage.
Microsoft Hyper-V:
• Based on Windows, wide hardware coverage, easy to
  manage, heavily tested. New and will take time for
  market to trust it.
             MS or VMware For Me?

Important – think long term! :
• Costs
• Skills availability
• Manageability
• Will the vendor still be in this market in 5-7 years
  time?

I’d choose Microsoft Hyper-V.

Clustered Firewalls




                                                                 Remote Network
                                                                  Administration




                      Core Switches




                                                                      Virtual Connects




                      Ethernet Backplane




                                                                          ILO
                                                                                         Remote Hardware
                                                                                          Administration



                        Blade Servers

                  Fibre Channel Network / SAN


                            Redundant
                      Fibre Channel Switches




                         San Controllers
                                                Remote SAN
                                                Administration
          Why Blade and SAN?
• Flexible storage
• Denser CPU deployment
• Less power consumption

• There might be larger capital/installation
  costs.
• Operating costs are lower.
          Virtual Connections
• Abstracted MAC address
• Abstracted World Wide Name

• Diskless Servers
• Servers => Replaceable Appliances
   Server Hardware Virtualisation
• HP Chassis: 16 Servers
• Deploy 15 + 1 Hot Spare

Production server dies => Hot Spare started
                       Virtualised Storage
Traditional Disk                 Virtual Disk
RAID Array -> LUN -> Partition   Disk Group -> Virtual Disk (RAID) -> Partition


  Why Virtualise Storage?
  • Quick to deploy
  • Quick to modify
       You’ve Got To Manage This!
• Microsoft System Center
          –   Operations Manager 2007 SP1
          –   Configuration Manager 2007 SP1 (in testing)
          –   Virtual Machine Manager 2008 (in testing)
          –   Service Desk 2009, 2010 or 2011? 

•   Cradle-to-Grave management
•   Integration
•   Customer visibility
•   Reduced administration – really!
