InfoQ posted a very interesting video from the ‘Democratizing the Cloud’ presentation by Erik Meijer in QCon.
Democratizing the cloud means “Make easier to program distributed applications”. He wants us to build a single tier app and publish it in multiple tiers.
Of course that we’d love to have that.
The only element that I don’t find consistent with his vision is the ‘refactoring’ he needs to split the applications in tiers. Up to then, all the magic was performed by the compilers and runtimes, but for this one we need different code, so once the decision is made, it cannot be changed. He talks about ‘making irreversible decisions at the last responsible moment’. The problem is to agree when that moment is ;). Things like ‘code webservices as if they are stateful’ probably are a heresy for some people.
This kind of functionality has only been provided by code generation tools, where you generate multiple tiers or single tier applications from the same specification, but never at the language level.
He also has some interesting opinions on SQL and DSLs.
