Enterprise Server Structure and Security Practices Layout?

[jxl1145]

Hello,

My question is:

From a production / Enterprise server layout can someone help give input on layout?

I am just learning.

For my KVM's:

I have a physical server, 4 KVM's: 2 server VM's, 2 client VM's

I am wondering about real-life set-ups?

I assume at least one physical server ? The Domain Server?
Then either several other physical servers for possibly other functions or using KVM's like a DNS, FTP, Proxy servers?
I've been told you would do this because it minimizes production impact since the VM's are only doing one main service?

I also assume roll-over VM's and / or back-up images setup to minimize downtime?

Thank You,

Lowry

I apologize, this may need moved to networking, but it also may be under security regarding Proxy, Firewall, and reduced downtime. Note sure.

I'm not sure what you're asking, but yes having each VM doing a single thing is a good idea. Then you can cluster VMs for redudency if you need to.
