Pub sub using .Net Services

In one of my last posts I spoke about pub-sub using WS discovery. Now I want to speak about the implementation of pub-sub using .Net Services.

.Net services is a future infrastructure running on the cloud that will provide ISB (Internet service bus) capabilities. The .Net services includes an access control infra, an orchestration infra, an addressing infra and finally a messaging infrastructure. I will go deeper on each of those on future posts.

The messaging infra comes in the form of WCF bindings so for anyone who uses WCF it is very easy to learn and use. Using this infrastructure solves critical communication problems for services deployed on different networks on the web. For example communicating through a firewall or bypassing NAT.

The main idea is the use of the mediator pattern (Microsoft Data Centers). If all parties can communicate to the mediator, communication can be established between them.

The messaging infrastructure introduces several messaging patterns. One of them is Pub-Sub. This is done using a binding called "netEventRelayBinding" There is a great example on the .Net Services SDK.

So if you want to enjoy pub-sub between networks on the web do not spend time and money on development of the infrastructure. Someone had done it for you. Consider using the .Net Services. We are now in the CTP phase but it is important to know where we are heading…
