Problems solved by technology

[0002] Although there have been a lot of research on server integration and many methods have been put into practical application environments, there are still some deficiencies and shortcomings in the current research. For example, some data centers use manual methods to integrate servers Integration will lead to very high labor costs, and it will easily lead to untimely response, which will affect the quality of service and the final experience of users; some integration algorithms use static integration strategies to integrate servers, and this method cannot be timely based on the real-time needs of users. Changes will cause energy waste; some integration algorithms only focus on a few dimensions of the server for integration without considering the overall perspective, so they cannot well meet the requirements of dynamic server integration and may easily lead to frequent migration of virtual machines , and then cause migration jitter and service quality decline, so people urgently need a new server integration method to solve the above problems
