Overview

Service Overview

Virtual Server is a virtual server optimized for cloud computing that lets you freely allocate and use infrastructure resources provided by the server—such as CPU and memory—without having to purchase them individually, and you can allocate as much as you need, when you need it. In a cloud environment, you can use resources with optimized performance according to the user’s computing purposes such as development, testing, and application execution.

Features

• Easy and convenient computing environment setup: Through a web-based Console, users can easily use Self Service from Virtual Server provisioning to resource management and cost management. * When using a Virtual Server, if you need to change the capacity of major resources such as CPU or Memory, you can easily scale up or down without operator intervention.

• Various Service Types Offered: Provides virtualized vCore/Memory resources based on predefined server types (1~128 vCore).

  • General Virtual Server: Provides commonly used computing specs (up to 16vCore, 256GB)
  • Large-capacity Virtual Server: Provided when resources larger than the standard Virtual Server spec are required.

• Strong Security Implementation: Through the Security Group service, control inbound/outbound traffic communicating with the external Internet or other VPC(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 a Virtual Server, you can modify it immediately using the server type edit function.
• Standard Server Type and Image Provision: Provides virtualized vCore/Memory resources according to the standard server type, and supplies a standard OS Image.
• Storage Connection: Provides additional attached storage besides the OS disk. * Block Storage, File Storage, Object Storage can be additionally connected and used.
• Network Connection: You can connect the Virtual Server’s standard subnet/IP settings and Public NAT IP. * Provides a local subnet connection for inter-server communication. * This task can be edited on the detail page.
• Security Group Application: Through the Security Group service, control inbound/outbound traffic communicating with external internet or other VPCs to securely protect 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 recover Virtual Server Image using the Backup service.
• Cost Management: You can create, stop, or terminate servers as needed, and because billing is based on actual usage time, you can verify costs according to usage.
• ServiceWatch Service Integration: You can monitor data using the ServiceWatch service.

Components

Virtual Server provides standard server types and standard OS images. Users can select and use it 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 the Virtual Server you are using, and you can 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.
• For instructions on creating and using images, see the How-to guides > Image document.

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: Creates a user credential for connecting to the Virtual Server.
• Retrieve Public Key: You can retrieve the public key by loading a file or by manually entering the public key. Keypair 생성 및 활용 방법은 How-to guides > Keypair문서를 참고하세요.

Server Group {#server-group}

Server Group 설정을 통해 Virtual Server 및 Virtual Server 생성 시 추가한 Block Storage를 랙(Rack) 및 호스트에 근접 또는 분산 배치 가능합니다. 주요 기능은 다음과 같습니다.

Server Group 생성: 동일 Server Group에 소속된 Virtual Server를 Anti-Affinity(분산배치), Affinity(근접배치), Partition(Virtual Server와 Block Storage 분산배치)로 설정할 수 있습니다.
