It is interesting that the issue of how green IT can be viewed as is coming to the fore. I was recently sent a notification of the existence of the following site:

Among its articles is this one about the green IT:

The article concentrates surveys about the state of green IT, and the lack of trust that IT purchasers have in the “Green” claims of suppliers. The rush to green wash products is leaving many, me included, sceptical that the benefits extend to the environment and purchasers bank balance – rather than the suppliers.

I find it interesting that both Google and Yahoo are getting involved in super computers – and hiring or loaning out the results to others. The following article makes the point:

Yahoo! outsources! India’s! giant! supercomputer!

This is a HP/Yahoo initiative that seems to be a match for a recent IBM/Google move. Continue reading ‘From the news: Computing power for hire’ »

It would seem that “Service Oriented Architecture” (SOA) is taking off as a technology in fashion. As usual, most of the news is generated by people wanting to sell it as the next big thing ready for the prime time. If followed as it is being sold at present, the concept is liable to lead to significant performance problems. SOA is sold on having a large number of “users” who are then often other systems. This is followed all the way back to the real users through an unknown number of tiers. The complexity of managing this sort of architecture increases significantly as the number of tiers increases. If this is then managed without due consideration for managing the system capacity and performance the result will be problems in the future. That is not to say that I don’t see a benefit in the overall technology – there is great potential. Just consider carefully how the performance of operational systems might be proven to be sufficient for the long term.
