Hi guys! Previously, I’ve published the 3nd of 4 parts of my study notes useful to pass the Oracle Cloud Infrastructure Foundations 2020 Associate. Today I share with you the 4rd part which speaks about pricing and billing, the free tier and about SLAs and support. But before starting, let me list a review of the sections.

Part 4

4.1 Pricing and Billing

• arguments : pricing models, examples, billing, cost management, free tier

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 $
