Distributed Processing 
Pick any two:
1. Available
2. Consistent
3. Partition Tolerant

8 Fallacies of Distributed Computing by Peter Deutsch
The Network is reliable
Latency is zero
Bandwidth is infinite
The network is secure
The topology doesn't change
There is only one Administrator
Transport cost is zero
The network is homogeneous

Distributed systems are complex
It's a paradign shift
Communication is the key

Messaging:
Smart endpoints, dumb pipes, distributed routing

Types of Coupling:
Spatial - physical links
Platform - Can a Java app talk to .Net? 
Temporal - time based


Going distributed solves problems, but it's more complex and requires different thinking.

NServiceBus does heavy lifting.  It's not free, but Colin thinks it's well worth it.  $25 or $30 bucks per machine per month.

NServiceBus can use AzureServiceBus, RabbitMQ, MSQueue, or SqlServer.
