Pricing models

  • PAYG (pay as you go) :
    • charged only for the resource consumed
    • no upfront commitment
    • no minimum service period
    • usage metered hourly
    • consumption based model for services like Oracle Functions
    • trades Capex for Opex
  • Monthly flex (Universal Credits)
    • minimum of 1000 $ of monthly charge and minimum of 12 months fixed commitment
    • savings 33–60 % vs PAYG
    • discounts based on size of deal and term of deal
    • usage is consumed from monthly prepaid commitment
  • BYOL (Bring your own license) : not truly a pricing model
    • apply your current on-premises Oracle licenses to equivalent services on IaaS & PaaS in the cloud
    • complete license mobility with on-premises

Factors that impact Pricing

  • resource size : n.CPU, storage space, etc.
  • resource type : VMs vs BMs , BYOL vs managed DBs, VMs vs Functions
  • data transfer :
    • no costs for data incoming into the cloud with OCI
    • pay attention for outcoming data (egress costs)
    • all regions have the same prices
  • OCPU per hour
  • VM and BM are the same price because it is for single CPU, but BM has 52 cpu while with VM you can configure 2,4,8, … cpus

Block volume pricing

  • storage cost (GB/month) : 0.0255 $
  • performance cost (VPU/GB) : VPU = volume performance unit
    • basic : NA
    • balanced : with 10 VPU : 0.0017 $
    • higher performance with 20 VPU : 0.034 $
  • example : 100 GB of block volume
    • basic : 200 IOPS, storage = 0.0255 x 100 $ = 2,55 $ , performance = 0 $ , total = 2.55 $
    • balanced : 6000 IOPS, storage = 2,55 $, performance = 0.17 $ , total = 2.72 $
    • higher performance : 7500 IOPS, storage = 2,55 $, performance = 3.4 $ , total = 5.95 $
