The difference between traditional architecture and virtualization

The differences between traditional architecture and virtualization are as follows:

1. Physical infrastructure

Traditional architecture: Only one operating system is allowed on a physical machine.

Virtualization: A physical machine can realize that multiple virtual operating systems can run multiple application software at the same time. Type flow. This helps to make the container light and start quickly.

2. In architecture.

Physical architecture: it is difficult to move or copy, limited by a specific set of hardware components, and its life cycle is usually short, requiring manual operation to upgrade the hardware.

Virtual architecture: easy to move and copy (encapsulated in files, independent of physical hardware), easy to manage (isolated from other virtual machines, unaffected by hardware changes), able to support old applications and realize server integration.

3. Enjoy resources * * *

Virtual machines can share resources quickly.

Physical machine needs hardware equipment (mobile hard disk) to realize.

4. On the cpu and memory.

Physical machines restrict and fix cpu and memory, and after virtualization, they can freely allocate cpu and memory according to their own needs (which has obvious effect in service applications).

5. Physical network and virtual network

The physical network can only implement a single network card.

Virtual network can allocate multiple virtual network cards to use through virtual switches.

The advantages of virtualization are obvious. However, virtualization operation and maintenance has brought great challenges to engineers. Chen Mingzhi Hang Yun 'an Virtualization Application Performance Monitoring and Management System can make virtualization transparent, allow operation and maintenance engineers to quickly find problems through graphics and color classification, and quickly locate problems according to Yun 'an Big Data Analysis System, greatly reducing troubleshooting time.
