What’s the difference?

Locked

I don’t understand what the different between a “private cloud” and “SOA” would be.

One is really a subset of the other

Service Oriented Architecture means you don’t reinvent the wheel and deploy duplicate and redundant services, while Cloud computing really means it’s all transparent and centralized.

The subtle difference is that there may be some things (e.g. legacy apps) that you may be able to shoehorn into a cloud-computing model, but in order to make them work, you’re going to throw the whole SOA model out the window. (e.g. multiple authentication services, multiple proprietary databases, etc).

Having four databases or three authentication services can all live happily in the cloud, but is that really good SOA archiecture? No.

In my view SOA means good architecture (applications behaving well), and Private Cloud means a nice pretty playing field for the apps to play on.

In the theoretical world, where all apps are perfect, SOA and CC are really the same thing.

But in the real world, I would expect that business requirements take these concepts in radically different directions.

That’s my opinion, I could be wrong….
