Velocity

Hi,

Microsoft project code named “Velocity” provides a highly scalable in-memory application cache for all kinds of data. By using cache, you can significantly improve application performance by avoiding unnecessary calls to the data source. Distributed cache enables your application to match increasing demand with increasing throughput by using a cache cluster that automatically manages the complexities of load balancing. When you use “Velocity,” you can retrieve data by using keys or other identifiers, named “tags.” “Velocity” supports optimistic and pessimistic concurrency models, high availability, and a variety of cache configurations. “Velocity” includes an ASP.NET session provider object that enables you to store ASP.NET session objects in the distributed cache without having to write to databases, which increases the performance and scalability of ASP.NET applications.

“Velocity” can help scale your .NET applications easily and cheaply by allowing you to bring the memory capacity of multiple computers into a single unified cache. In addition, it also helps in dynamically scaling your application as your application needs grow by allowing the dynamic addition of computers to the cluster. “Velocity” can store all your application data—reference, activity or resource data—while giving you the performance, scale, and availability that you need.

For community technology preview 3 (CTP3), Microsoft project code named “Velocity” offers several enhancements and a new API. The enhancements include a cache notifications feature, performance improvements, security enhancements, and new cluster management options. There are also updates to the installation program. Perhaps the most material change for the “Velocity” administrator is that your options for editing the cluster configuration settings have been decoupled from your options for storing the cluster configuration settings. For more information, see the What’s New topic in the product documentation.
