Real artists ship

There is life after one project is announced. Banco de España -Spain's central bank- selected Microsoft for Target2 a couple of years ago.

The solution, built on top of Biztalk, is not very demanding from a functional or performance point of view, but is pretty critical -it handles cross-borders payments over 50K euros-.

I worked for that project for more than one year between 2006 and 2007, leave it on the testing phase, and now is up and running. That's one of the better feelings working on software.

The title, "Real artists ship", is a phrase from Steve Jobs. I like the phrase a lot and the story is sad but true :).

More than one thousand orchestrations per second

Finally it's public, last summer I worked on a benchmark in order to prove the viability of BizTalk processing 62 million messages (with orchestrations involved) each day. That means more than 1,000 messages per second.

It was pretty fun, we started with a very small number -as usual on performance testing-, and grew up until 1,156 messages per second.

Building from scratch

Architecting systems you can build from scratch or evolve an existing one. A lot of pros and cons on both, but one of the pros of the new ones is how clean can be.

I have been for some time with SlaterLabs, building a core banking solution in .NET. As soon as we started to have the first bits we went to a HP lab in Stuttgart to see if we can compete on the big leagues.

The figures were amazing, more than 7,000 business transactions per second with a average response time under .1 second.
