您最近虚拟化了哪些类型的服务器? [英] What kind of servers did you virtualize lately?

问题描述

我想知道您在过去的 6 个月内虚拟化了哪些类型的内部使用服务器.以下是我们目前获得的虚拟内容:

I wonder what type of servers for internal usage you virtualize in the last -say- 6 months. Here's what we got virtual so far:

• mediawiki
• 错误追踪器(螳螂)
• 颠覆

我们没有对运行特定软件产品的专门化台式电脑进行虚拟化，这些软件产品只是偶尔使用一次.您打算尽快摆脱那些旧机器吗?

We didn't virtualize spezialized desktop PCs which are running a certain software product, that is only used once in a while. Do you plan to get rid of those old machines any time soon?

您使用哪些服务器产品?Vmware ESX、Vmware Server、Xen 安装...?

And which server products do you use? Vmware ESX, Vmware Server, Xen installations...?

推荐答案

我对此类问题的标准回答是虚拟化很棒；请注意它的局限性".

My standard answer to questions like this is, "virtualization is great; be aware of its limitations".

我绝不会依赖任何基础架构级服务的纯虚拟实现(例如，您站点的权威 DNS 服务器；管理和监控工具).

I would never rely on a purely-virtual implementation of anything that's an infrastructure-level service (eg the authoritative DNS server for your site; management and monitoring tools).

我在一家提供服务器和网络管理工具的公司工作.我们一直在努力克服虚拟化供应商的营销策略，因为基础架构工具不应该存在于基础架构工具中.

I work for a company that provides server and network management tools. We are constantly trying to overcome the marketing chutzpah of virtualization vendors in that infrastructure tools shouldn't live in infrastructure tools.

虚拟化想要控制您的所有服务.但是，有些东西应该始终存在于物理硬件上.

Virtualization wants to control all of your services. However, there are some things that should always exist on physical hardware.

当您的虚拟设置出现问题时，故障排除和恢复可能需要很长时间.如果您仍在物理硬件上运行公司所需的某些服务，那么您就不会陷入困境.

When something goes wrong with your virtual setup, troubleshooting and recovery can take a long time. If you're still running some of those services you require for your company on physical hardware, you're not dead-in-the-water.

虚拟化还引入了时钟延迟、磁盘和网络 IO 延迟以及您在物理硬件上看不到的其他问题.

Virtualization also introduces clock lag, disk and network IO lag, and other issues you wouldn't see on physical hardware.

最后，您选择的虚拟化工具将负责其托管虚拟机的所有资源.这转化为管理程序 - 而不是您 - 决定在任何给定时刻哪个 VM 应该具有优先级.如果您担心任何工具、服务或功能可以保证拥有某些资源，则需要在物理硬件上.

Lastly, the virtualization tool you pick then becomes in charge of all of the resources under its command for its hosted VMs. That translates to the hypervisor - not you - deciding what VM should have priority at any given moment. If you're concerned about any tool, service, or function being guaranteed to have certain resources, it will need to be on physical hardware.

对于任何无关紧要"的事情，例如网络、邮件、dhcp、ldap 等，虚拟化都很棒.

For anything that "doesn't matter", like web, mail, dhcp, ldap, etc - virtualization is great.
