Options to Decrease SPLA costs
• Create Server with one high speed processor – reduce cost by 50%
• Zero CAL Costs. No option to decrease here.
Options to Decrease costs for End User Agreements (Open Agreement)
• Do not buy Software Assurance
• Consolidate purchases to move to higher discount level
• Move to Select Plus or Enterprise agreement
• Analyze CAL requirements to decrease CAL costs.
Notable points
• Cost of server, server SA is equal to approximate 30 CAL licenses + SA.
• CAL costs are enterprise wide costs. Costs components cannot be attributed per server unless there is a total
organization wide Microsoft Licence cost comparison.
• If you have 30 CALS per server as average in your environment then costs for Open Agreement doubles
whereas it remains constant for SPLA.
• Open Agreement is cost to reseller they will charge margin on top of it. SPLA prices have reseller
margin inbuilt.
Replace Open Agreement costs with your Microsoft License Agreement costs to assess where your stand against cloud
service providers. 2
