How to use Compute Server

1. Operation Target

Users and administrators can perform operations such as reserving compute servers for servers that can be used by the user group to which they belong.

2. Using Compute Server

Cloud Bouquet allows compute servers to be used within a pre-defined region.
This section describes the steps involved in reserving, using, and terminating compute servers.

2.1. Confirming Compute Server Availability

Before reserving a compute server, confirm in advance if the specifications of the desired compute server are available for the desired period.

1. To check availability, open the 【Availability Calendar】 screen from the left menu.
   

2. From the left menu of the 【Availability Calendar】, select 「User Group」 and click the ［Filter by Server Type］ button to display a list of compute server specifications.
   

3. In 【Filter by Server Type】 （Compute Server Specifications List）, select your desired Plan and click the ［Select］ button.
   

4. The availability of the selected Plan is displayed as blocks on the 【Availability Calendar】 screen.
   The period during which blocks are displayed indicates that the Plan can be reserved.
   If you want to check the availability of another Plan, click the ［Filter by Server Type］ button again and select the Plan you wish to check.
   

TIPS!
Availability can be checked until the end of the month two months from the current date and time.
Ex.）
For 2024/12/20 10:00, the display period is 2024/12/20 10:00 to 2025/2/28 23:59.

TIPS!

• The following operations are possible on the 【Availability Calendar】 screen:
  • You can switch the displayed month using the ［＜］ and ［＞］ buttons at the top of the screen.
  • You can also directly select a specific month using the calendar in the upper left.
  • Under 「Server Availability」 in the lower left, you can narrow down availability by usage period.
    
    

    Item	Description
    day	Enter the period of use in days.
    over	Display servers that are available for more than the number of days entered.
    less than	Display servers that are available only for less than the number of days entered.

5. Clicking an availability block displayed on the calendar will show detailed information for the corresponding period and selected Plan.
   

6. Clicking a date on the calendar switches the display from month view to week view.
   In week view, periods that are already reserved are displayed as gray blocks.
   You can return to month view by clicking the ［MONTH］ button at the top of the week view calendar.
   

The above completes the procedure for checking availability before reserving a compute server.

2.2. Reserving a Compute Server

3. Check Usage Status

In Cloud Bouquet, you can check the usage history and fees for compute servers, including past usage.
This section explains the fee structure related to compute servers and how to check usage history.

3.1. Fee Structure for This Service

First, the fee structure of this service is explained.
The basic fee structure for compute servers is as follows.

• Point Consumption for Compute Server Usage
  • The number of points required to use a compute server is calculated based on the defined unit price and usage time.
  • The unit price is set per hour and can be checked on the compute server reservation screen, usage history screen, etc.
  • Usage time is calculated based on the time from the 「scheduled start time specified at reservation」 to the 「scheduled end time specified at reservation」.
  • The number of points consumed can be confirmed during the reservation process.
  • Usage time is counted as 1 hour for every 3600 seconds, with fractions rounded up. （Example: 1 to 3600 seconds is counted as 1 hour, and 3601 to 7200 seconds is counted as 2 hours.）
  • When the scheduled start time is reached, the launch process for the compute server begins, and it becomes usable approximately 5-15 minutes later.
  • It may take approximately another 2 minutes for the status to switch to 「Running」 on Cloud Bouquet after it becomes usable.

For operating conditions, please refer to About Points and Wallets.

• About Storage Servers
  • Storage servers can be installed individually upon customer request. For specifications and usage methods, please contact us.（Cloud Bouquet Contact）
