Authenticating your windows domain users in the cloud
Moving to the cloud can represent a big challenge for many organizations when it comes to reusing existing infrastructure. For applications that drive existing business processes in the organization, reusing IT assets like active directory represent good part of that challenge. For example, a new web mobile application that sales representatives can use for interacting with an existing CRM system in the organization.

Pub/Sub in the cloud–A brief comparison between Azure Service Bus and PubNub
Publish/Subscribe in the cloud has became relatively important lately as an integration pattern for business to business scenarios between organizations. The major benefit of using a service hosted in the cloud as intermediary is that publishers and subscribers don’t need to be publicly addressable, be in the same network or be able to talk each other directly. The cloud infrastructure allows this intermediary service to scale correctly as the number of publishers or subscribers increase, and also to act as a firewall for brokering the communication (Publishers or subscribers need explicit permissions to connect, send or receive messages from the intermediary service).

Troubleshooting your WCF Web Apis with AppFabric
In this last post, I showed how the new WCF Web Apis could be integrated with AppFabric for pushing custom events to the AppFabric tracking database. A great thing about the monitoring infrastructure in AppFabric is that is uses ETW as mechanism for publishing the events, so your services are not hitting the database directly with all the performance penalties that database calls imply.

Monitoring your WCF Web Apis with AppFabric

Monitoring your WCF services with AppFabric
Windows AppFabric (Previously known as Dublin) introduces a new built-in mechanism for monitoring the execution of the WCF services, all the events generated during the execution or the interaction with other services. While the message trace capabilities in WCF already provided some detail about the execution and the exchanged messages, it was a feature more suitable for troubleshooting and error diagnosis. The performance counters did not help in this area either, as they provided live service usage statistics, which sometimes resulted very useful to determine possible bottlenecks.
