Amazon Web Services

Other day I was hiring a dedicated server. In doubt about whether choose between windows 2003 standard or web server. I’ve chosen the standard one. It has message queuing system and I needed it so much. Then stumbled at Amazon Web Services – Then I felt myself stupid. They provide Queuing services and worse – at very cheap price.

That comes as lesson… nowadays we can just architect solutions without take into account the new approach of services in the cloud. Amazon Web Services is just a sample which provides a lots of interesting services like Storage (very cheap), scalable mysql server (not that cheap but considerable if you’re really doing business) and many others.

I know there are other service providers which in my point view still needs clarify what services they provide and what cost is going to be at end. I’ve seen some services about cloud computing which always appear to be more expensive than it should. They also miss details which makes me unable to calculate exactly what I going to need.
How I would know how much processor cycles my application is going to need in month? Still not comfortable these days, hope it get better!

Legacy applications today

Well… today it’s common to find muticore computer. Obviously much powerful than the ones from past decades.

Business at all levels has powerful muticore computers but I doubt that most transactional business application is prepared to advantage from this architecture and actually make use of all available resource.

Doing parallel system is quite different from doing multithread system. Even the latter one is very scarce. Such models need differents structure algorithms.

Now, imagine a service oriented environment, inside SaaS ecosystem. A little bit further you migth find a candidate main service. These one we’ll be requested from many different requestors. Would you imagine how busy it will be? There’s a lot to take advantage from parellelism and concurrence but most of applications developed at moment are already legacy ones.

If you want some abstract or academically thought, try this wikipedia or microsoft side of the force.
Also, Josh Phillips is doing a very nice job at his blog.
