Windows Server AppFabric was designed to support a variety of customer scenarios, ranging from small shops with a handful of developers to larger, more sophisticated environments that require support for scalable and highly available hosting and management of mission critical composite applications and services.
While designing for high availability could fill several chapters of this book, a good starting point is to demonstrate an approach for scaling Windows Server AppFabric with Microsoft Network Load Balancing (NLB). NLB is a capability that is battle proven since its release with Windows NT 4.0 and provides a relatively simple way to scale Windows Server AppFabric.
Note
NLB is a clustering technology which is available in Windows Server and is designed to provide high availability, reliability, and scalability of TCP/IP based hosts, such as IIS.
NLB is particularly well suited for scaling traffic across multiple hosts in a cluster (known as cluster hosts) and supporting automatic...
