This is a classic model, and datapipe and other programs are implemented in this way. The advantage is that the implementation is simple, convenient for transplantation, and sufficient performance can be provided. The disadvantage is that the machine with multi

At the same time, Cloudstack is helping many world-class telecom and technology companies, such as BT, China Telecom, KDDI, NTT, Nokia and DataPipe. One last piece of advice If you are seriously considering OpenStack or Cloudstack, and have dedicated IT teams to take the time and acquire the necessary skills, we strongly
