, requiring the system to be highly transactional and able to handle as many transactions as possible in a unit of time. Obviously, the load characteristics of these two environments are completely different.From a NUMA architecture, it can integrate many CPUs within a physical server, making the system highly transactional, and minimizing data interaction between different CPU modules due to remote memory access Shiyan longer than local memory access

Virtualization, grid computing, utility computing, and other technologies ). However, can Private clouds solve all problems? Of course the answer is no! Because databases and other memory-or I/O-intensive (Note: they are intensive) applications, they are currently not suitable for use in cloud computing environments. This is caused by a situation known as "falling into" by the industry. Compared with CPU-intensive applications, memory-or I/O-intensive applications consume a very small amoun
