3. Only the individual rows will be locked while the In-memory table read/write operations and storage procedures could also use In-Memory technology to improve the performance.
4. As per the released SQL server 2014 news’s, front-end applications are not required to be rewritten to use In-Memory technology. But the existing databases need to be modified to use In-memory technology. You can also find a demo code from Microsoft.

SQL Server 2014’s AlwaysOn technology was built to enroll Windows Azure virtual machines running SQL Server into a customers’ disaster recovery solution.
