個人的にSQL Server のプレゼンテーションで気になった箇所を抜粋します。
Microsoft touted the benefits of the "conscious design choice" to build the Hekaton technology into SQL Server 2014, with no need for a separate data engine. "Other vendors are either introducing separate in-memory optimized caches or building a unification layer over a set of technologies and introducing it as a completely new product," said Dave Campbell, Microsoft technical fellow, when Hekaton was announced as a coming component of SQL Server 2014 last November. "This adds complexity forcing customers to deploy and manage a completely new product or, worse yet, manage both a 'memory-optimized' product for the hot data and a storage-optimized' product for the application data that is not cost-effective to reside primarily in memory," Campbell said.
The Microsoft exec also noted SQL Server 2014 will include improvements to the AlwaysOn feature, supporting "new scenarios, scale of deployment and ease of adoption."
