Blade Servers Rack-Mount Servers
• Greater compute density
• Less cables / rack space
• Less expandable
• Less internal storage
• Scale-out
• Lower compute density
• More cables / rack space
• Much more expandable
• Much more internal storage
• Scale-Up

28.  Physical Servers = You own ALL of it / co-locate
 Virtualization = You own it, you deploy it, you manage it
 Private Cloud = On-premises automation

not your datacenter

you rent compute time

you self-service it

31. IaaS
 Full functionality
 Windows must be
managed
 HA & DR up to you
 SLA at VM level
 Scale – just add
resources
DBaaS
 Database only
 No SQL Agent
 Patches / upgrades
automatic
 Built-in HA & DR
 SLA at DB level
 Scale by Tier
© Heraflux Technologies® 32
PaaS
 Instance only
 SQL Agent (?)
 Patches / upgrades
automatic
 Built-in HA & DR
 SLA at instance level
 Scale by Tier

33.  Careers in IT are more than just programming
 Many layers exist underneath the database / application
 Each piece of the puzzle depends on the other pieces
 Careers can be made from just one layer
 “The only constant is change”
 Explore! Enjoy!
