Comparisons against physical servers

Classification Physical server-based computing ucloud server
Flexibility - Limited capacity depending on the existing physical system
H/W delivery, installation, and replacement required for expanding capacity
- Extend by simply clicking "new cloud server"
Promptness - Setup times for delivery, or installation;
Hardware maintenance time required
- Service provided within 5 minutes by automatically assigning resources 
- No need for H/W maintenance
Stability - Easily out of service from hardware errors 
System Redundancy required for reliable security
- Spare cloud resourcesavailable; prompt recovery from errors
- No dependency to system redundancy
Cost efficiency Purchasing costs for hardware, including spare capacities for reliability
Operation costs for Network/Field/Electricity
- Flexible provision of capacity; Charged by actual usage 
- Elimination of additional server operation costs

Case study

  • 1Game server (N Game Company)

    Necessary costs reduced over by 50% during service expansion (440 mil./4 years ¡æ80 mil./4 years)

    Management and maintenance costs reduced by over 30% from projected costs

    Over 99% of service expansion set-up time reduced (From ~8 hours to 10 minutes)

  • 2Mobile Application Server (B Company)

    Instant service expansions protects new enterprises from unexpected traffic or events (3 servers in normal operation ¡æ during events)

    48% reduced costs compared to using hosting services

  • 3Web server for News Network (H Press)

    A website with irregular spikes in traffic, causing congestion (due to nature of news media); congestions easily re-routed to cloud's dynamic servers

    Yearly costs using hosting would be ~2.5 times their costs using uCloud

  • 2 Monitoring service

    Provides information on current resources and current usage within cloud environment and helps stabilize the cloud environment by setting threshold and offering alarms for different events

    Go
  • 3 Load Balancer

    Removes traffic congestion on a specific server by dispersing load to each server with dedicated devices

    Go
  • 4 Snapshot/Image

    Saves the state of disk volume in Cloud server and enables a user to return to that state whenever they wish

    Go
  • 5 CIP (Cloud Internal Path)

    Composes a separate internal network environment on Cloud server (VM) and provides an environment where shared services (ex. cloud NAS, backup, etc.) can be used and Inter-AZ can be composed

  • 6 scale up/down product

    Expand or reduce specifications of currently operating cloud server

    1. - Ex: A cloud server of 2vCore 2GB can be scaled up to 4vCore 4GB or down to 1vCore 1GB.

    ※ Changes (scale up/down) can be made only on standard products signed up since March of 2012 onwards and selectable specifications listed up depends on OS and current operating condition in use. (This function is to be provided later on High-memory and SSD server products.)

    ※ VM must be stopped before changing products
