Overview

Service Overview

Virtual Server does not require individual purchase of infrastructure resources such as CPU and Memory provided by the server; it can be freely allocated and used as needed at the required time, serving as a cloud computing-optimized virtual server. 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 perform everything from Virtual Server provisioning to resource management and cost management via Self Service. * 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.

• 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 Spec (up to 16vCore, 256GB)
  • Large-scale Virtual Server: Provided when large resources exceeding the standard Virtual Server specifications are needed.

• Strong Security Implementation: By using 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 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 besides the OS disk. * Block Storage, File Storage, and Object Storage can be added and used together.
• Network Connection: You can connect the Virtual Server’s standard subnet/IP settings and Public NAT IP. * Provides a local subnet connection for communication between servers. * This task can be edited on the detail page.
• Security Group applied: By using the Security Group service, you control inbound/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 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 usage.
• ServiceWatch Service Integration Offering: You can monitor data through the ServiceWatch service.

Component

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 also create an Image by uploading your Image file to Object Storage.
• Create Shared Image: You can create a Shared Image from an Image with Visibility set to Private, making it shareable.
• Share with another Account: You can share the Image with another Account.
• For instructions on creating and using images, refer to the How-to guides > Image document.

Keypair

To ensure more secure OS access, 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 for connecting to the Virtual Server.
• Retrieve Public Key: You can retrieve the public key by loading a file or by directly entering the public key.
• Refer to the How-to guides > Keypair document for creating and using keypairs.

Server Group

Through Server Group settings, the Block Storage added when creating a Virtual Server can be placed near or distributed across racks and hosts. The main features are as follows.

• Server Group Creation: Virtual Servers belonging to the same Server Group can be set as Anti-Affinity(distributed placement), Affinity(proximate placement), Partition(Virtual Server and Block Storage distributed placement).
• Refer to the How-to guides > Server Group document for creating and using Server Groups.
