5. III. Virtualization Architecture
5
Virtualization architecture includes:
1. Hosted architecture.
2. Bare-mental architecture.
3. Hybrid architecture

6. 1. Hosted architecture
6
Pros and cons:
a)Advantages
- Ease of installation and configuration.
- Unmodified host OS and Guest OS.
- Run on a wide variety of PC.
b) Disadvantages
- Performance degradation.
- Lack of support for real-time operating system

7. 2. Bare-mental architecture
7
Pros and cons:
a)Advantages
- Improved I/O Performance.
- Support Real Time OS.
b) Disadvantages
- Difficult to install & Configure.
- Depends upon hardware platform.

1. Advantages

19. - Their using for the storage of mutable data is relatively costly
compared to a trusted, centralized service;
- The promising basis that they provide for client and host anonymity
has not yet resulted in strong guarantees of anonymity.
