Concept of virtualization
Virtualization is a technology that allows creation of an abstraction (a virtual version) of physical components (e.g. hardware device). With this abstraction, a single machine can act like several machines working independently or multiple machines as a single machine. It is a core technology for cloud computing by providing shared resources for users.
Definition of virtualization
Virtualization is defined as a technique for hiding the physical characteristics of computing resources from the way in which other systems, applications or end users interact with those resources. The commonly used term refers to the followings:
- 1Operating multiple systems on a single physical machine.
- 2Making CPU, memory, HDD and NIC logical using software.
- 3Converting physical server unit to application unit.
Types of virtualization technology
table
| Types of virtualization technology |
Description |
Application
Virtualization |
- Applications installed separately on the user’s PC Virtualization can be provided through virtualization.
- This enables delivery of applications on-demand without having to install the applications on the PC.
|
Desktop
Virtualization |
- Server-side desktop virtualization enables a user to virtually own dissimilar desktops with different operating programs such as Windows Vista and Windows 7.
- Client-side desktop virtualization makes it possible to operate dissimilar virtual desktops within a PC.
- A separation between personal operating space and company operating space is possible with such method.
|
Server
Virtualization |
- By integrating and consolidating dozens of physical server workloads in a data center into a couple of virtual servers, you can reduce physical overhead costs, administrative costs, and IT energy consumption, and improve the utilization of server resources.
|
Storage
Virtualization |
- A service can be implemented by allocating the minimum space required through virtualization using the technology called “Thin-Provisioning” instead of using physical storage required.
- It also provides an environment for integration of different storage systems.
|
Network
Virtualization |
- It allows you to use L2, L3, L7 switches, network firewalls, and security devices that are available in the form of hardware appliances as virtual machines. Networking resources operate separately even in a single shared physical environment through virtualization.
|
Expected benefits of virtualization
Virtualization technology can improve the utilization of ICT resources in terms of flexibility, security, and scalability while reducing maintenance costs by sharing, pooling, emulating and encapsulating the resources. It also ensures interoperability and protects your investments on the existing systems. To summarize, virtualization lowers a company's TCO(Total Cost of Ownership), increases the flexibility and efficiency of utilizing ICT resources by sharing them.

What is cloud service?
A new paradigm that enables the use of more efficient and economical IT environment without having to own various IT resources and functions
- Use IT resources and functions at anytime, anywhere
- Only pay for the amount you have used
- No complex installation process
- Fast scalability
- Measured service
Cloud service allows users to use services without having to purchase IT resources and pay for the service like using electricity as a service.
Cloud computing enables a payment system based on the amount of service used.
Why do we have to use cloud service?
You can use the service at a reasonable price at anytime, anywhere as long as you have internet connection. It also provides safe and flexible working environment for improved productivity.
- 1You can use the service anywhere.
-
As long as you have internet connection,
you can use the service anywhere with the same
environment as your office.
You can work outside your office with a PC,
tablet PC or smart phone.
- 2It is economical.
-
You only have to pay for the service you have used.
It saves you the cost of purchasing, operating
and maintaining IT resources.
- 3It keeps your data safe.
-
Your data is stored in a data center with the advanced disaster prevention technology and uninterrupted systems.
Triple data storage/backup keeps your data safe.
24 hours a day, 7 days a week monitoring system prevents any unauthorized access and hacking.
- 4It improves your productivity.
-
Flexible working environment (e.g. working from home) can improve your productivity.
Outsourcing IT operation and maintenance helps you focus on your core business.
Cloud service models
Cloud computing service models come in three types:
SaaS (Software as a Service),
PaaS(Platform as a Service),
IaaS (Infrastructure as a Service).
Saas
- Software as a Service
-
Provide software as a service for users through internet
Paas
- Platform as a Service
-
Provide platform as a service for system implementation
Iaas
- Infrastructure as a Service
-
Provide IT infrastructure as a service for system and service construction

Considerations for introducing cloud
The advancement of cloud computing allows companies of any size to optimize their IT investments, achieve economies of scale, reduce costs and drive business innovation
- 1Network traffic
-
Need to build infrastructure that has reliable access to centralized IT resources through network
Need to secure sufficient network bandwidth based on work environment, information system and user environment
- 2Misuse and abuse of centralized information
-
Recommended to establish information management and operation polices in response to misuse and abuse of information
Need to establish and apply access control policy based on the importance of data
- 3Unstable service
-
Service must be planned according to the application service types, characteristics and operation pattern as in the cloud environment, various types of software and solutions share common computing resources
Recommended to set mid- to long-term plans to secure operation strategy and system for cloud-based IT resources
- 4Risk of information leakage
-
Need to build security systems for each service and system (e.g. application, server, network, data) against cyber-attacks and hacking as corporate and personal data is centralized and managed
Classification by service user
- Cloud computing service implemented internally for companies and organizations
- Can be modified for easy use by each company/ organization
- Managed by company/ organization's managers
- Cloud computing service for specific groups
- Access granted only to its members
- Data and application programs are shared among the members
- Public cloud is an essential cloud service model
- Provide resources such as programs and storage devices to several users
- (Examples)
DUZON, Ndrive, DropBox
- Service combining public and private cloud services
- Private cloud service for business data
- Public cloud service for non-business data
