An impressive list. However - how do you choose the right tool for your needs? "What is the best tool for ..." is usually rejected in SO (and other Stack Exchange sites). A "Stack Overflow for tools" recommendations, pros and cons would be great.
Under virtualization:
XenServer -- it has Xen, but most SysAdmins wont use raw Xen, but instead a complete hypervisor such as XenServer or VMware, etc.
XenServer was recently re-rereleased and now is 100% open source (all features). Now you get all the "enterprise" features in the freebie Open Source version.
Under SMTP Servers:
Zimbra - excellent top-of-class email server, and open source.
Kinda off-topic, and you might be the wrong person to ask, so, sounds like a plan! Which hypervisor would likely be the best on Ubuntu 14.04. It'd be for a single, fairly low-utilization system. Looks like 14.04 has support for Xen, KVM, and VMware. As I said, low utilization, virtualizing a couple of linux boxen and a single Windows box.
Everyone else feel free to join in on the discussion (i'm probably breaking all kinds of site rules, aren't I?:) It's a greenfiield setup so I'd like to start with what the folks around here might recommend.
If one of the choices is correct by a very margin, let me know that's the case and I'll go checkout that path. Thanks!
Very good resources link. Thank you for sharing and keeping this thread alive on top. But all of them are not integrated to sort of interoperate leveraging each other's resources.
Is there any project that integrates these different projects? Is there sufficient interest in the group to use sort of selected items as distro?
Are there any takers for such an initiative? May be just focusing on Management and monitoring part to start with?
That's the problem we're trying to solve at Leanstack.io, but without the Q&A interaction: http://leanstack.io/platform-as-a-service. Would love to hear your feedback: yonas[at]leanstack.io.
As someone new to a lot of this stuff, I'd love to also add a best practices section.
Like for example in SSH it would talk about setting up keys, and turning off features that make it less secure (can't think of which off the top of my head)
