Service Overview

Virtual Server is a cloud computing-optimized virtual server that lets you freely allocate the amount you need at the required time without having to purchase infrastructure resources such as CPU and memory individually. In a cloud environment, you can use resources with optimized performance according to your computing purpose, such as development, testing, and application execution.

Features

Easy and convenient computing environment setup: Through a web-based Console, users can easily perform self-service provisioning of Virtual Servers, as well as resource and cost management. If you need to change the capacity of major resources such as CPU or Memory while using a Virtual Server, you can easily scale up or down without operator intervention.
Providing various types of services: Provides virtualized vCore/Memory resources according to predefined server types (1~128 vCore).
- General Virtual Server: Provides commonly used computing specs (up to 16 vCore, 256 GB)
- High-capacity Virtual Server: Provided when resources larger than the standard Virtual Server spec are needed.
Strong Security Implementation: By using the Security Group service, you can control inbound/outbound traffic communicating with the external Internet or other VPCs (Virtual Private Cloud) to securely protect the server. Additionally, real-time monitoring enables stable operation of computing resources.

Provided features

Virtual Server provides the following features.

Auto Provisioning and Management: Provides Virtual Server provisioning, resource management, and cost management functions through a web-based Console. If you need to change the capacity of major resources such as CPU or Memory while using Virtual Server, you can modify the server type immediately using the server type modification feature.
Standard Server Types and Image Provision: Provides virtualized vCore/Memory resources according to standard server types, and offers standard OS images.
Storage Connection: Provides additional attached storage beyond the OS disk. Block Storage, File Storage, and Object Storage can be attached and used.
Network Connection: You can connect the standard subnet/IP settings of the Virtual Server and the Public NAT IP. Provides a local subnet connection for inter-server communication. This can be modified on the detail page.
Security Group Application: Use the Security Group service to control inbound and outbound traffic communicating with external internet or other VPCs, thereby securely protecting the server.
Monitoring: You can view monitoring information for computing resources such as CPU, Memory, and Disk through the Cloud Monitoring service.
Backup and Recovery: You can back up and restore the Virtual Server Image using the Backup service.
Cost Management: You can create, stop, or terminate servers as needed, and since billing is based on actual usage time, you can monitor costs according to consumption.
ServiceWatch Service Integration: You can monitor data using the ServiceWatch service.

Component

Virtual Server provides standard server types and standard OS images. Users can select and use them according to the desired service scale.

Image

You can create and manage images. The main features are as follows.

Image creation: You can create an Image from the configuration of a Virtual Server you are using, and you can also create an Image by uploading your Image file to Object Storage.
Create Shared Image: You can create an Image with Visibility set to Private as a Shared Image that can be shared.
Share with another Account: You can share the Image with another Account.
Refer to the How-to guides > Image document for how to create and use images.

Keypair

To ensure a more secure OS login, we strengthen security by providing a Key Pair instead of the ID/Password entry method. The main features are as follows.

Keypair creation: Generate a user credential to connect to the Virtual Server.
Retrieve Public Key: You can load a file or manually enter the public key to retrieve it.
Refer to the How-to guides > Keypair document for creating and using keypairs.

Server Group

Through Server Group settings, you can position the Block Storage added when creating a Virtual Server close to or distributed across racks and hosts. The main features are as follows.

Server Group Creation: You can set Virtual Servers belonging to the same Server Group as Anti-Affinity(Distributed placement), Affinity(Proximate placement), or Partition(Virtual Server and Block Storage distributed placement).
Refer to the How-to guides > Server Group document for how to create and use Server Groups.

Reference

Linux operating systems such as Alma Linux and Rocky Linux provide only even Minor versions, except for the final release of a Major version. This policy ensures the stability and consistency of the SCP system. We recommend checking the EOS (End of Support) and EOL (End of Life) dates for the operating system, and, if necessary, applying new or additional individual packages to maintain a stable environment.

Server type

The server types supported by Virtual Server are as follows. For detailed information about server types, see Virtual Server Server Types.

Constraints

Reference

When creating a Virtual Server with Rocky Linux or Oracle Linux, additional configuration is required for time synchronization (NTP: Network Time Protocol). For other images, it is set automatically and no separate configuration is needed.
For more details, refer to Linux NTP Setup.
If you created RHEL and Windows Server before August 2025, you need to modify the RHEL Repository and WKMS (Windows Key Management Service) settings.
For more details, see RHEL Repo and WKMS Configuration.

2 - Monitoring Metrics

Cloud Monitoring service termination notice

According to Samsung Cloud Platform’s policy, the Cloud Monitoring service is scheduled to be discontinued in September 2026.
Starting after the September 2026 release, resource monitoring of the Samsung Cloud Platform via Cloud Monitoring will no longer be possible.

With the new alternative service, you can continuously perform resource monitoring by leveraging ServiceWatch released in October 2025.
ServiceWatch provides more modern and powerful features, replacing Cloud Monitoring to deliver a seamless monitoring environment.

Detailed information about ServiceWatch can be found in the ServiceWatch Overview.

Virtual Server Monitoring Metrics

The table below shows the monitoring metrics of Virtual Server that can be viewed through Cloud Monitoring. For detailed usage of Cloud Monitoring, refer to the Cloud Monitoring guide.

Provides basic monitoring metrics even without installing an agent, as shown below table. Please check the Virtual Server monitoring metrics (default). Additionally, the metrics that can be viewed by installing the Agent are in the table below. Virtual Server additional monitoring metrics (Agent installation required)** Please refer to it.

For Windows OS, memory-related metrics can only be viewed after installing the Agent.

Table. Additional monitoring metrics for Virtual Server (Agent installation required)

3 - ServiceWatch Metrics

Virtual Server sends metrics to ServiceWatch. The metrics provided by default monitoring are data collected at 5‑minute intervals. If detailed monitoring is enabled, you can view data collected at 1‑minute intervals.

Reference

For how to view metrics in ServiceWatch, refer to the ServiceWatch guide.

See How-to guides > ServiceWatch Enable Detailed Monitoring for instructions on enabling detailed monitoring of Virtual Server.

Basic Metrics

The following are the basic metrics for the Virtual Server namespace.

The indicators whose names are displayed in bold below are the indicators selected as key metrics among the default metrics provided by Virtual Server. The key metrics are used to build service dashboards that are automatically generated for each service in ServiceWatch. They can also be viewed on the Monitoring tab of the Virtual Server detail page.

Each metric provides guidance in the user guide on which statistical value is meaningful to query, and among the meaningful statistics, the values shown in bold text are the primary statistics. In the service dashboard or monitoring tab, you can view primary metrics using these primary statistics.
