Openstack – a cloud management system

Recently, I am studying Openstack. It’s a cloud management system, especially it’s announced by open source.

why do you need cloud management system?

First of all, I don’t believed that your enterprise can stand on a single environment of virtualization, and also will no need to use public cloud. for cost issue, maybe you will apply for Amazon cloud service or windows cloud or else, so in some big-scale enterprise environment, I believed that you will stands on the situation of hybrid cloud.

so-called hybrid means that Public + Private cloud.

when you face so many cloud solution in front of you, the real difficultly should be how to manage it between different cloud like public cloud of amazon or windows and your private cloud at home.

so in such a situation, you will need a cloud management system.

openstack can let you manage public and private cloud resources. and then your infrastructure should be robust and flexible for your enterprise.

I will try to build up a testing environment later. and then i will update the newest status in blog.

如何變更VNCSERVER解析度(How to re-define the resolution of vncserver in Linux?)

我在家中時,經常使用WIN7工作站,使用VNC CLIENT連入遠端LINUX SERVER操控
I always used to control my remote linux server via VNC client when I am home.

但內定的解析度太低,大概只有1024*768,視窗太小
If you adopt the default setting of VNCSERVER, it’s only about the resolution of 1024*768, it’s too narrow to operation.

如果不夠大,需要在LINUX啟動VNCSERVER時,輸入以下指令
If you would like to enlarge it, you should input the command as below when you try to enable VNCSERVER service.

vncserver -geometry 1280×960 -depth 16 -dpi 100 :1
