Thanks to Nicholas Carr everyone loves to talk about Cloud Computing as
electricity and how we are transitioning from own power-stations to central
grid. After a lot of discussions about "the cloud", it occurred to me
recently that there is a far better model to make cloud idea easy to
understand - and it is supermarket.
Electricity is kind of a wrong model. Not because so many folks are now
trying to get the pendulum swing back and get to solar panels and other
micro-generators, but also because software and IT services are much less
uniform than electrical current. There's no single "IT utility current" you
can get from your network outlet to solve all IT needs.
Supermarkets seem a far closer paradigm. There was a period of natural
household economy when basically people were raising their own crops and more
or less producing most of the stuff they needed day to ... (more)

Overall, very exciting times, and a great event put together by the folks at
SYS-CON! There was a lot of excitement and optimism throughout the event. As
someone put it: cloud computing is about 700 days old. That means that there
are a lot of arguments about definitions, and where things are going, and so
on. And that also gives a lot of vibe and a lot of fresh community spirit.
Below are my notes from all the sessions I attended at the last week’s
Cloud Computing Expo 2008 on:
Day 1 Day 2 Day 3
A few general comments on the conference.
First and foremost,... (more)
Azure Session at Cloud Expo
Pundits talking about how Windows 7 is all about Microsoft competing against
Apple, recovering with Vista consumer adoption disaster, or getting people
off of XP, are missing one other – extremely important – part of the
Windows 7 story. Windows 7 and its server counterpart – Windows Server 2008
R2 – are actually the first real step in Microsoft’s Windows Cloud Story.
Before Windows 7 Microsoft could offer some services (such as Exchange
Online) from the cloud – but could not provide full enterprise directory,
security and so on – now they can.
What do enterprise IT architects need to know about the Cloud? What is the
difference between SAML and OAuth? Can you really host an AD domain
controller in the cloud? How do you enable single sing-on (SSO) between
Active Directory and Salesforce.com? Microsoft’s Office 365 or Google Apps?
What is the state of art for security and compliance in the cloud?
These are just some of the questions which are probably going to be discussed
at The Experts Conference 2011 in Las Vegas, April 17-20 2011.
If these questions are relevant to you – register today and get the early

Don’t put all eggs in one basket! June 14, 2012 outage at Amazon Web
Services affected many customers and other clouds that rely on AWS (e.g.
Heroku). Instead of going back to the “is cloud reliable” debate, we need
to acknowledge that no single service will ever be 100% reliable, and only
real solution is using more that one service provider.
Remember when Apple launched their iCloud service last year? Remember what
made them architecturally so different from 99.9% of other “cloud”
services out there? They used both Amazon Web Services and Microsoft Windows
Azure as the underly... (more)
