Problems solved by technology

Because the image files that make up the cloud desktop are relatively large, generally tens of GB, it takes a lot of computer resources and storage resources during the switching process of the cloud desktop, especially when switching in batches, it may cause resource preemption and shortage, thus consuming more Long mirror shutdown and startup time, reducing the user experience of quickly switching cloud desktops

Embodiment 1

[0043] Such as figure 1As shown, a cloud computing image library (301) includes a base image 1 (101), a base image 2 (102), a base image 3 (103) and an incremental image 1 (201), an incremental image 2 (202), Incremental image 3 (203) and several other images.

[0044] The basic image 1 (401) and the incremental image 1 (501) constitute the cloud desktop VM1 (601), and the basic image 1 (403) and the incremental image 2 (503) constitute the cloud desktop VM2 (603).

[0045] When switching between cloud desktops, compare the basic image in cloud desktop 1, that is, base image 1 (401), with the basic image in cloud desktop 2, that is, basic image 1 (403). Since the basic images are both basic image 1, you can keep the basic image .

[0046] Compare the incremental image in Cloud Desktop 1, that is, Incremental Image 1 (501) and the incremental image in Cloud Desktop 2, that is, Incremental Image 2 (503). Since the incremental images are different, you need to switch the increm...

Embodiment 2

[0052] image 3 What is shown is an example in an actual education scenario. Assuming that resources are fully loaded and there are no more computing resources, users (students and teachers) hope to switch between classes in batches within 5-10 minutes of break time. 100 cloud desktops, which is about switching the cloud desktop classroom template composed of different templates from Java courses to C++ courses. Include the following steps:

[0053] A1: Java classroom cloud desktop 1 is composed of basic image 1 (112) and incremental image 1 (111), and cloud desktop 2 to cloud desktop 100 are composed of the same basic image 1 (112) and incremental image 1 (111). .

[0054] A2: C++ classroom cloud desktop 1 is composed of basic image 1 (114) and incremental image 2 (113), and cloud desktop 2 to cloud desktop 100 are composed of the same basic image 1 (114) and incremental image 2 (113). .

[0055] A3: Identify and compare the basic image 1 (112) of Java classroom cloud des...

Abstract

The invention provides a method and a system for switching cloud desktops with same hardware, the method segments a cloud desktop mirror image file, and then identifies and compares sameness and difference of basic mirror images and incremental mirror images of a target cloud desktop and an original cloud desktop; by means of retaining the same mirror images and switching the different mirror images, data required to be updated when switching the cloud desktops is reduced, cloud desktop switching time is reduced; further, the basic mirror images and the incremental mirror images are stored independently, the incremental mirror images are classified into hotspot, normal and cold data types, the basic mirror images are cached in a high-speed solid state disk, the hotspot incremental mirror images are stored in an internal memory, the normal incremental mirror images are stored in a solid state or mechanical hard disk, and the clod incremental mirror images are stored in the mechanical hard disk or other high-capacity storage devices, thus, cloud desktop switching speed is accelerated, system cost is reduced, and fast switching of large concurrent cloud desktops is supported.

Description

technical field [0001] The present invention relates to the cloud desktop application field of cloud computing, and more specifically, to a method and system for switching cloud desktops in large batches and quickly. Background technique [0002] Cloud computing has become a hot term in science and technology. It is a resource-sharing computing model that provides available, fast, and low-cost cloud services. The cloud desktop is a typical cloud computing application. The cloud desktop truly realizes the mobility of work, and has good platform independence and portability. As long as the network is smooth, users can choose terminal devices to log in on any occasion. Go to the cloud desktop, open your own work desktop to work, and enjoy cloud services. [0003] In actual application scenarios, especially education scenarios, under the condition of limited resources, different courses need to be switched within a short time interval (5-10 minutes) between classes, and one clo...
