2. Realize improved service and metrics with minimized financial impact

3. Introductions Why Development Environments? Why Virtualization? Technology Nuggets Questions Welcome!

4. Introductions  Brian Huntley  Manager of Network Operations  Tim Antonowicz  Systems Engineer

5. Critical to improved customer service Routine in large-scale applications Built-in change-management D/R potential Why Development Environments?

6. Improved Customer Service  Encourage systems staff to test changes  Sandbox for new ideas, requests  Production system changes  More predictable  More reliable  Take less time  Long-term outages

7. Routine In Large-Scale Applications  Why?  Most business-critical environment  Financial impact  Operational impact

8. Built-In Change Management  Policy/Procedure  Practicality

9. Disaster/Recovery Potential Hot Spare Highly portable Easy to backup Easy to test restores

10. Disaster/Recovery Potential  Safe place to test backups!

11. Inexpensive Highly-portable Easy roll-back of changes Why Virtualization?

12. Inexpensive  Fractional hardware cost  Software inexpensive or free  Minimal setup time  Converters from physical to virtual

13. Highly Portable  Easy to back-up  Easy to move from host to host  Easy to deploy after disaster

14. Easy to Roll Back Changes  Perfect for development  System wide “oops” undo is trivial  Non-persistent disks  Logging disks

15. VMware Options Microsoft Options Open Source Options Hardware requirements Technology

16. VMware Options  Infrastructure 3  Commercially Licensed  VLAN configurations  Virtual Network Switches  Performance Tuning  High-Availaiblity  VMware Server  Zero cost  Simple installation on host OS

17. Microsoft Options  Virtual Server R2  Free depending on use  Limited guest OS support

18. Open Source Options  Xen  OpenVZ  VirtualBox  Varying levels of  Stability  Performance  Features  Requires Open Source operating system experience

19. Hardware Requirements  Dependant on software configuration  Memory and disk space crucial  CPU bottleneck for large numbers of guests  Fast disk important

20. Virtual Environments Benefit Because: Have value-add potential Improve stability of production Sandbox for ideas D/R plan Integration Implementation Options Various vendors available Each has advantages and disadvantages Host system hardware can become large Costs Low Software inexpensive or free Relative hardware cost is low when spread across all systems Admin time to set up is minimal Nuggets
