1.5. Example Usage Model¶

This section provides examples of service combinations used for different usage applications.

When Used As a Test Environment/Development Environment

Required Features/Requests	Used Services and Notes
I want the performance of the servers and networks to be Best Effort, and I want to keep the cost down as much as possible. I want to use a free OS. I want to prepare resources in the shortest time.	Compute Resource: Use the Standard with the Compute Class (CPU/Memory) and storage class (Disk) Internet Connectivity: Use 10 Mbps Best Effort Private Catalog: Use Private Catalog to upload CentOS Can be prepared in the shortest time of 5 business days

When Building an In-house File Server

Required Features/Requests	Used Services and Notes
I want to use it directly with the Arcstar Universal One service (the NTT Communications VPN service). I want to change the Disk write frequency and request speed by server.	Internet Connectivity: Do not use VPN Connectivity: Use Compute Resource: Use the Compute Resource Pools separated by server (differentiate between the Compute Resource Pools that use the Standard and Premium Disk capacity)

When Building a New EC Site

Required Features/Requests	Used Services and Notes
I want to precisely distribute the communication load to servers. I want to control resources in real time. I want to precisely guarantee the Internet bandwidth. I want to increase the performance of resources according to usage.	vLoad Balancer: Use (distribute the server access load) Internet Connectivity: Use the guaranteed type Check the Customer Portal performance statistics report and add resources in real time

When Using the Cloud for Multiple Systems

Required Features/Requests	Used Services and Notes
I want to separate network segments so that I can separate them into multiple systems. I want it to be easy to operate because I will be managing many servers.	Server Segment: Add Server Segments and build a complex network Compute Resource: Separate and manage Compute Resource Pools by system

When Outsourcing an Application Server That Demands Performance for Data I/O

Required Features/Requests	Used Services and Notes
I want to reliably secure Disk I/O. I cannot physically accommodate another contractor on the same server, so I want to use the cloud on a dedicated physical server.	Compute Resource (Dedicated Device): The server equipment and storage devices in the cloud infrastructure are used by having a physical server in a physical enclosure dedicated to you

When Outsourcing an Infrastructure That Cannot Be Installed on the Same Hardware As Another Business, Due to the Security Policy

Required Features/Requests	Used Services and Notes
I want to reliably secure Disk I/O. I cannot physically accommodate another contractor on the same server, so I want to use the cloud on a dedicated physical server.	Compute Resource (Dedicated Device): The server equipment and storage devices in the cloud infrastructure are used by having a physical server in a physical enclosure dedicated to you

When Implementing a BCP

Required Features/Requests	Used Services and Notes
I want my system to be in a robust Data Center rather than keeping the data within my company. I want to back up my data in another country.	In Enterprise Cloud, the cloud infrastructure resides in robust Data Centers (characteristic of a carrier), regardless of which service you are using. Global File Storage (Global Data Backup): Important data is saved in a remote overseas location in real time
