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)
This was mostly spawned from this: http://sabok.org which several LOPSA members have contributed to. Everyone has their own flavor of "What's the best" & "How to do Sysadmin", there's no real definitive list for anything. There's also http://ops-school.readthedocs.org which seems to be more focused on DevOps instead of real Sysadmin.
Founder of http://sabok.org here. Thanks for the mention! I used to work with the founder of Ops School -- we're still in touch and we're both gung-ho about effective ways to make more sysadmins / ops engineers.
I'll be submitting things for sure. The more resources we have like this the better. Also, if you are interested in this type of stuff, I recently wrote an essay on "Bits Sysadmins Should Know", talking about sysadmin career advice and the main systems you will likely use @ http://sysadmincasts.com/episodes/25-bits-sysadmins-should-k...
Very good list. I do wish some of the entries had a more to their description than "written in Blub." Knowing the language is interesting but not really helpful if I just want to know functionality.
Of all the things I think this list is missing, I think the #1 is the backup software lsyncd: watches a local directory tree for changes, then uses rsync to copy the changes. Great for when your data become so large that you can't complete your periodic backup job in a reasonable period of time.
I have a problem with "cloud storage." Most of those are simple file sync services and they have nothing to do with "the cloud".
OwnCloud for example, is just a php app used for syncing files with different clients. It is not distributed, the data is not replicated, there is no High Aveilabilty(HA) setup. Seafile could has HA if you pay.
The only true cloud storage system there is Swift. And CEPH is missing, which is a big player in cloud storage.
I may be wrong here, but cloud should be HA, scailable and distributed.

http://leanstack.io/categories is a pretty big repository of such services.
Edit: or maybe you mean services which offer the equivalent OS software as a Saas?
Hopefully the lack of comments here means everyone is submitting pull requests to the repo instead of posting their favourite missing resource on here. ;-)
