呵呵,自己搞? 那投资不小。
以前在hp时,搞过云平台中的一小部分,但那时不算infra的建设,只算上层的一部分应用。
现在接触的只是些本地化的平台,没到云那个阶段。
不过在本地摸索的时候,接触了vmware的vsphere, 这功能确实相当的强,但是license也是相当的贵。特别其中的vsphere Vmotion和 storage vmotion的功能无比强大。 我觉得很多云平台应该都是用的这个机制。 建议你看看了解下
http://pubs.vmware.com/vsphere-5 ... 1-D17365731E68.html
vSphere vMotion
Enables the migration of powered-on virtual machines from one physical server to another with zero down time, continuous service availability, and complete transaction integrity.
Migration with vMotion cannot be used to move virtual machines from one datacenter to another.
vSphere Storage vMotion
Enables the migration of virtual machine files from one datastore to another without service interruption. You can place the virtual machine and all its disks in a single location, or select separate locations for the virtual machine configuration file and each virtual disk. The virtual machine remains on the same host during Storage vMotion.
