Example cost: Virtual Private Cloud (updated)
Feb 10th
Back in September, 2009, I had written a post with a quick overview of what a private cloud (or infrastructure) looks like and some basic costs and information, including why it is a great product (I am biased).
Since then, Dell has retired the PE2900III model server and items change, this is an update for the basic configuration.
Reminder graphic:
2 Servers, 1 firewall
So, originally, the physical servers were configured as:
- Dell PE2900III (reasonably priced, very reliable, I have spares on the shelf)
- 4 ethernet ports (2 built in, 2 port card installed, more can be added)
- 2 73GB SAS drives mirrored together for booting VMware vSphere 4
- 32GB RAM (48GB is max for this hardware platform)
New servers look like:
- Dell PET610 (reasonable price, very reliable, spares to go onto the shelf)
- 4 ethernet ports (all built in)
- 2 80GB SATA drives mirrored together for booting VMware vSphere 4
- 48GB RAM (192GB max available – very expensive)
The reason for the RAM change is that I am seeing a 2:1 (or higher) ratio of RAM to CPU usage in terms of percentage, and 48GB is a good place for this sized system. Also, the newer Xeon 55xx series processors uses RAM sticks in 3s instead of 2 or 4 at a time. 48GB is 12 4GB sticks of RAM. The newer 55xx series of processors also has working hyper-threading (or H/T) and I am seeing very nice performance on servers deployed using this processor family in our network.
Cost difference? The original posting listed had estimated the cost at $1,600.00 per month (see previous post), and I estimate this to be very close, inching up to approximately $1,700.00 per month, and this number should be high. (for accurate pricing, please contact ipHouse sales people, they can run up a quote based on real numbers)
Apache 1.3 – you were loved
Feb 4th
So, across my RSS feed today, I saw a blurb…
Apache terminates ‘outated’ web server
What?
I clicked the link and was sent off to The Register for their report on the issue.
Apache 1.3 was released in July, 1998 – 12 years ago, and still in operation today.
At ipHouse – we use 1.3 as the tried and true Apache webserver on our cluster. We’ve not had either issues or problems; and security updates are few and far between. I guess after 12 years no one cares anymore to hack such old code or something.
Goodbye Apache 1.3, we had a long relationship, but your sister is younger and better equipped for todays Internet. Don’t cry, we’ll remember you fondly.
Hello Apache 2.2 – we are look forward to a long relationship on our network behind our F5 load balancers.
*sniffle*
Summary: Apache 1.3.42 is the final release according to the Apache Software Foundation. They recommend moving to Apache 2.2.14. Apache 2.0 will end once Apache 2.4 has been released, and finally, Apache 2.3.5 is in alpha stage.

Shell service available
Jan 29th
Been a long week and I had to deal with some red tape internally (of my own creation!), but finally have some working shell service to sell to people who want it.
I had posted last week about the issue(s) of shell services and decided that I would do the work to put this kind of service together as I have both the experience and gumption to do so. Even includes my smiley, happy-go-lucky support attitude!
So it is available and sales is ready to take the orders. I don’t expect a lot of people signing up for this, but it takes care of a sect of customers that still want to do things in a manner that isn’t web based, that isn’t all mouse driven.
I can relate to that!
- Ubuntu Hardy
- FreeBSD 8
- emacs, vi, joe
- mutt (no elm, no pine – all Maildir oh well)
- procmail filtering
- IMAP, POP3, SMTP, with SSL and STARTTLS goodness
- reasonable and ample disk storage quota on our NetApp gear
Let the nerding begin!
The new iPad hype
Jan 29th
What’s the issue really?
Oh noes, no camera? That’ll change I bet.
No flash? Win in my book!
No multitasking? Really, you wanna run more things, buy a computer.
Now, the speculation about version 2 makes me laugh, but really, aren’t we at version 3? In my office common area, I have version 1, and I’ll include a picture.
Back to the iPad – just sit back and see what really happens. We are 60-90 days out (minimum) before it hits the shelves, maybe a surprise will come. Like tether-ability! That’d be win.
And as promised…and yes, it still works, and is not for sale.
For those about to write..
UNIX Shell services, what’s the fuss?
Jan 21st
Wowzers, quite a little thread going on in a newsgroup, but really, what’s the big deal?
I think I know…
Not everyone uses the Internet for viewing web pages and downloading pr0nself-help videos and television shows. The Internet itself has become much easier for the layman to use, and with that, these historical services are no longer needed and support for them is harder and harder to come by.
In the past, most service providers (especially the ISPs that service residential users) used to offer some kind of UNIX shell for their paying clientele. Over time, the number of service providers has decreased, and of those that are left, the percentage of them that offer this type of environment has decreased by orders of magnitude. I’ll speculate on why further down this post.
UNIX shells are fascinating experiments in shared computing resources with a very long history.
