Pace
• “Copy and Paste”• Pre-release
• Test new versions on exact production duplicate• 2 week project done in 1 hour• We now do OTPortal releases every 2 weeks• New time-saving features sooner
• Design Feasibility• Create new servers and test concepts using production
data• New Technology Used with less risk
Saving Time

Total Cost of Ownership
• Old TCO• 26 Physical Dell Servers, variety of specifications, versions, bios, CPU, memory
configurations, need lots of different spares• 52 power supplies• 26 Backups, 26 Anti-virus, 26 machines to network and patch• 4 Cisco network switches• 2 racks in the data center• 100+ network cables• Half a dozen power strips• Hours and hours to upgrade disks• Downtime to upgrade memory
• Cloud TCO• 2 servers + SAN+2 network switches• 2 power strips• Quarter of a Rack
• Obvious• If you Manage IT Equipment you can “Feel the Savings” by seeing this list• Save 50% on Hardware, 90% on Management
It’s about saving Money

Uptime Improved
• Server Failure• N+1 Hosts mean…• Every virtual server we create is protected from a failed
hardware server• Would have required an additional 26 servers!
• Upgrades• Memory – upgrade 1 server at a time• Disks – 2 mouse clicks and a reboot
• Backup and DR• Single backup process for each host• Backups for every virtual server on all hosts• <4 hour RTO for all 26 servers (75% is for Exchange alone)

Performance
• Old Days• Get the right RAM/Disk/CPU
(few days?)• Schedule downtime (2 day to
1 week notice)• Shut down the server• Remove it from the rack• Open server install additional
resources• Boot server• Test performance – hope we
added enough• Turn the server back off so we
can re-rack it• Restart the server• 2 hour downtime
“I need more power Scotty”
• Cloud Days• Schedule downtime• Click to add more
RAM/Disk/CPU• Reboot server• Test performance• 5 minute downtime
• Entire Cloud• Upgrade hardware one
host at a time• Practically 0 Downtime
