Overview

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.
