See Inside a Google Data Center and a Google Server
Google has recently provided some unprecedented views into their data center operations and have even revealed current details of their server board. In the past they have only released information on old designs (like the 80 PC rack given to the computer history museum). It seems like every time photos would pop up of server parts it would end up being of a previous generation of equipment. For the most part, folks like me have only dreamed of being able to see inside a real Google data center and seeing real operational, current generation Google equipment.

Android: Disruptive? Not enough info to say
Google and T-Mobile just announced the arrival of the G1 device today. This is the first cell phone to use Google's new open "Android" operating system. Android will almost certainly change the mobile computing fabric. It is the first open and free mobile platform and since it is backed by Google it is not going to be a flash-in-the-pan. But, now the question is, how disruptive will it be? There are over 3.3 Billion active cell phone subscribers in the globe. How many of those will eventually be on Android?
I'd appreciate any of your thoughts on that. For now, check out some of Android's features below. Looks pretty cool.
We still don't know when these will be in the local phone stores. But then again, we don't know when the Blackberry Bold will be here either. Anyway, I plan on evaluating an Android phone as soon as possible to see if it is for me.
More later.

How fast is 3G and what is 3.5G and when will 4G be here?
Most enterprise CTOs are very interested in the "cloud" and ways to tap
into cloud-based resources. An interesting aspect of this discussion
has been how to access the cloud while on the move. Today's cellular
networks support that access today, and future enhancements are making
that support even better and much much faster.
How much faster? I'll try to put that in context in this post.
Early 3G network to had a download speed of 384kbits per second and an
upload speed of 192Kbits per second. The wireless router you might
have in your home, by contrast, might have a speed of 54Mbits per
second. So, about 140 times faster.
But the 3G networks in place today use new transmission algorithms that
enable much faster throughput. Here is a little more context from
vendor pages:.
Verizon asserts their broadband access, based on CDMA2000 1x EVDO (Code
Division Multiple Access Evolution-Data Only) provides download speeds
of up to 1.4Mbits/s and uploads of up to 800kbits/s.
AT&T is leveraging its GPRS technology called EDGE to deliver
higher speeds that Verizon's. AT&T's EDGE delivers speeds of
around 1.7Mbits/s and upload of around 1.2Mbits/s.
Sprint asserts that its broadband cards delivery 350-500kbps but then say you might get a peak of 3.1Mbps. I wonder if or how often that happens.
What's coming next:
A key emerging protocol is HSDPA (High-Speed Downlink Packet Access). HSDPA is
sometimes called 3.5G. This protocol is in the HSPA (High Speed Packet
Access) family and allows download of up to 14.4Mbits/s download and
5.8Mbits/s upload. Now this is getting interesting.
HSPA+ allows speeds of up to 42Mbits/s. This is almost what you would
expect to see in your home wireless LAN. The next step is a project
called Long Term Evolution. This LTE will start with providing
150Mbits/s to handheld devices and soon thereafter expect protocols and
algorithms to increase that upto 1gig of bits per second to your mobile
device.
When will these new protocols and speeds be available to consumers?
The answer is, the best roadmaps I have seen are all tightly held insider
views, but if you look at what is being rolled out right now we should
expect a continuing stream of announcements that brings the timing of
these new protocols more into focus. Public information show many
vendors moving to the first version of LTE by 2011. Indications I'm
getting are that it
will be accelerated into 2009.
So, brace yourself for the innovation that will drive in the devices that connect to the cloud through cellular.
