[CPU] How to calculate the specifications of an Oracle Cloud instance [Core License]

This is Ohara from the Technical Sales Department

This articleOracle Cloudfor
explains how to calculate instance specifications and usage fees
compares them with Amazon Web Services (AWS).
*This explanation will use IaaS as an example.

Summary: Overview and Features of Oracle Cloud [Key Points]

First, compare the CPU units of "Amazon Web Service" and "Oracle Cloud"

Oracle Cloud uses the unit"OCPU"to represent CPU resources, and
even in the cloud, the service is provided as "physical CPUs."
For example, one physical CPU is calculated as "1 OCPU," and two physical CPUs as "2 OCPUs."

If Oracle Cloud has "1" OCPU (physical CPU), 
(virtual CPUs) in Amazon Web Services (AWS)
it is equivalent to "twice" the number of vCPUs

■ Calculation example:
・Oracle Cloud: 1core (1 OCPU) = AWS: vCPU 2core
・Oracle Cloud: 2core (2 OCPU) = AWS: vCPU 4core
・Oracle Cloud: 4core (4 OCPU) = AWS: vCPU 8core

Even in the cloud, calculations are based on the "core license" method

for information on Oracle Cloud's IaaS pricing structure
please refer to the following official URL

■ Oracle Software Licensing in Cloud Computing Environments
https://www.oracle.com/assets/cloud-lic-170290-ja.pdf
==============================================

For example, if we assume that a cloud environment requires "4 cores per instance,"
AWS would calculate this based on the specifications and performance of "vCPU, ECU, and cores."

To meet the requirement of "4 cores per instance,"
Oracle Cloud requires the allocation and calculation of "2 core" core licenses.

■ Calculation example:
• AWS: Required number of cores for a VM instance "EC2": vCPU: 4 cores
• Oracle Cloud: Required number of cores for a VM instance "Virtual Machine": 2 cores (2 OCPUs)

Oracle Cloud page listed on
Using the VM instance "VM.Standard2.1"
and calculating with "2" core licenses, the calculation formula is as follows:

■ Example calculation (approximate) for Oracle Cloud (VM instance):
VM.Standard2.1 (¥7,656 / 1H) × 744H × 2 cores = ¥11,392.128 / 1 instance price (monthly)

Compare specifications and prices

, based on the following cloud environment deployment requirements
for both AWS and Oracle Cloud
let's actually calculate the approximate specifications and usage

==========================================
■ We are considering migrating our infrastructure from an on-premises environment (physical servers) to a cloud environment.
■ We require an infrastructure environment that can withstand mission-critical workloads.
■ Minimum instance specifications required per server

• CPU: 4 cores
• MEM: 8GB
• HDD (Storage): 1TB
• Data transfer volume (Outbound): 1TB or more
• OS: Windows Server

* In the Oracle Cloud environment,
the calculation of "Windows Server OS" is also based on "core licenses".
==============================================

Based on these requirements, the specifications and usage fees are calculated
as shown in the table below.

* Machine uptime/month: 744H
* AWS: Tokyo Region
* AWS: Converted to Japanese yen at 110 yen/dollar

 summary

This time, we looked at the specs and price comparison between AWS and Oracle Cloud

For companies considering adopting the cloud,
when you compare and consider both AWS and Oracle Cloud
we hope this article will be helpful
