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

This is Ohara from the Technical Sales Department

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

For more information on the features of Oracle Cloud , please refer to the following blog.

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), it is equivalent to "twice" the number of vCPUs (virtual CPUs) in Amazon Web Services (AWS)  

■ 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

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

=========================================
■ Oracle Cloud Infrastructure Pricing
https://cloud.oracle.com/ja_JP/iaas/pricing

■ 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)

Using the VM instance "VM.Standard2.1" listed on the official Oracle Cloud page as an example, 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

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

==========================================
■ 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, we hope this article will be helpful when you compare and consider both AWS and Oracle Cloud
