Service Overview

Virtual Server is a virtual server optimized for cloud computing that allows you to freely allocate and use as much as you need at the necessary time without purchasing infrastructure resources such as CPU, Memory, etc. provided by the server individually. You can use resources with optimized performance according to your computing usage purposes such as development, testing, and application execution in a cloud environment.

Key Features

Easy and convenient computing environment configuration: Through the web-based Console, users can easily use Self Service from Virtual Server provisioning to resource management and cost management. If you need to change the capacity of major resources such as CPU or Memory while using Virtual Server, you can easily expand or reduce without operator intervention.
Provision of various types of services: Provides virtualized vCore/Memory resources according to predefined server types (1~128 vCore).
- General Virtual Server: Provides Computing Specs generally used (maximum 16vCore, 256GB)
- High Capacity Virtual Server: Provides when large capacity resources larger than General Virtual Server Spec are needed
Strong security application: Protects servers safely by controlling Inbound/Outbound traffic communicating with external internet or other VPC (Virtual Private Cloud) through Security Group service. In addition, you can stably operate computing resources through real-time monitoring.

Service Architecture

Provided Functions

Virtual Server provides the following functions.

Automatic Provisioning and Management: Provides functions from Virtual Server provisioning to resource management and cost management through web-based Console. If you need to change the capacity of major resources such as CPU or Memory while using Virtual Server, you can change immediately using the server type modification function.
Standard server type and Image provision: Provides virtualized vCore/Memory resources according to standard server types, and provides standard OS Image.
Storage connection: Provides additional connection storage in addition to OS disk. You can use by additionally connecting Block Storage, File Storage, and Object Storage.
Network connection: You can connect Virtual Server’s general subnet/IP and Public NAT IP. Provides local subnet connection for communication between servers. This task can be modified on the detail page.
Security Group application: Protects servers safely by controlling Inbound/Outbound traffic communicating with external internet or other VPC through Security Group service.
Monitoring: You can check monitoring information such as CPU, Memory, Disk, etc. corresponding to computing resources through Cloud Monitoring service.
Backup and recovery: You can backup and recover Virtual Server Image through Backup service.
Cost management: You can create, stop, and terminate servers as needed, and since billing is based on actual usage time, you can check costs according to usage.
ServiceWatch service integration provision: You can monitor data through ServiceWatch service.

Components

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

Image

You can create and manage Image. Main functions are as follows.

Image creation: You can create the configuration of the Virtual Server in use as an Image, and you can create an Image by uploading the user’s Image file to Object Storage.
Shared Image creation: You can create a Shared Image that can be shared from an Image with Private Visibility.
Share to other Account: You can share an Image to another Account.
For Image creation and usage methods, refer to How-to guides > Image document.

Keypair

To provide more secure OS access, we strengthen security by providing Key Pair instead of ID/Password input method. Main functions are as follows.

Keypair creation: Creates user authentication for connecting to Virtual Server.
Import public key: You can import a public key by file upload or direct input of public key.
For Keypair creation and usage methods, refer to How-to guides > Keypair document.

Server Group

Through Server Group settings, you can place Virtual Server and Block Storage added when creating Virtual Server close to or distributed across racks and hosts. Main functions are as follows.

Server Group creation: You can set Virtual Servers belonging to the same Server Group as Anti-Affinity (distributed placement), Affinity (close placement), Partition (Virtual Server and Block Storage distributed placement).
For Server Group creation and usage methods, refer to How-to guides > Server Group document.

Fig. Virtual Server Additional Monitoring Metrics (Agent Installation Required)

3 - ServiceWatch Metrics

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

Reference

To view metrics in ServiceWatch, refer to the ServiceWatch guide.

For information on how to enable detailed monitoring for Virtual Server, refer to How-to guides > Enable ServiceWatch detailed monitoring.

Basic Metrics

The following are basic metrics for the namespace Virtual Server.

In the table below, metrics with metric names marked in bold are selected as key metrics among the basic metrics provided by Virtual Server. Key metrics are used to configure service dashboards that are automatically built for each service in ServiceWatch. You can also check key metrics on the monitoring tab of the Virtual Server detail page.

Each metric guides you on which statistic value is meaningful when querying that metric through the user guide, and the statistic value marked in bold among the meaningful statistics is the key statistic value. In the service dashboard or monitoring tab, you can view key metrics through key statistic values.

Performance Item (Metric Name)	Detailed Description	Unit	Meaningful Statistics
Instance State	Instance state display 1 - Active 0 - Off	None	Sum
CPU Usage	CPU usage	Percent	Average Maximum Minimum
Disk Read Bytes	Amount read from block device (bytes)	Bytes	Sum Average Maximum Minimum
Disk Read Requests	Number of read requests from block device	Count	Sum Average Maximum Minimum
Disk Write Bytes	Amount written to block device (bytes)	Bytes	Sum Average Maximum Minimum
Disk Write Requests	Number of write requests to block device	Count	Sum Average Maximum Minimum
Network In Bytes	Amount received on network interface (bytes)	Bytes	Sum Average Maximum Minimum
Network In Dropped	Number of received packets dropped on network interface	Count	Sum Average Maximum Minimum
Network In Packets	Number of received packets on network interface	Count	Sum Average Maximum Minimum
Network Out Bytes	Amount transmitted on network interface (bytes)	Bytes	Sum Average Maximum Minimum
