Example Embodiment
[0023] Example one
[0024] See figure 1 , Is a cloud platform system architecture diagram of the present invention. The cloud host resource reservation device performs actual operations based on the cloud platform system 100. Among them, the cloud platform system 100 includes:
[0025] The main control system 110 is responsible for the main cloud computing platform management work, including receiving, storing, and processing user request information, maintaining and storing cloud platform hosts and cloud host resources, and coordinating the scheduling and creation of cloud hosts.
[0026] The scheduling system 120 is responsible for scheduling the cloud host to the host cluster, and calculates whether it can be reserved and / or created for each cloud host applied for; if so, which host or hosts in the host cluster can be reserved and / or created On the host.
[0027] The host machine cluster 130 is a physical machine cluster that hosts the cloud host.
[0028] Among them, each host i...

[0042] Example two
[0043] See image 3 , Is a flowchart of a cloud host resource reservation method in Embodiment 2 of the present invention. This embodiment is further optimized on the basis of the technical solution of Embodiment 1 above.
[0044] Step 310: Receive a resource reservation request from the user.
[0045] Preferably, according to the number of cloud hosts requested to be reserved in the resource reservation request and cloud host specifications, the cloud host resources requested to be reserved are scheduled in the host cluster to determine the actual reserved resource information, which specifically includes the following step:
[0046] Step 321: Obtain the resource usage of each host in the host cluster.
[0047] Among them, the scheduling system in the cloud platform system obtains the resource usage of each host in the cloud platform. The resource usage includes at least the number of CPU cores, memory capacity, disk capacity, IP address, and network bandwidth us...
Example Embodiment
[0071] Example three
[0072] See Figure 4 , Is a flowchart of a cloud host resource reservation method in the third embodiment of the present invention. Based on the technical solutions of the foregoing embodiments, the user can create a cloud host that does not exceed the reserved number on the basis of the reserved resources of the cloud host at any point in the validity period. In addition, after the expiration date, the cloud platform will release unused cloud host reserved resources. The specific steps are as follows:
[0073] Step 410: Receive a resource reservation request from a user, where the resource reservation request includes the number of cloud hosts requested to be reserved, cloud host specifications, and reservation time limit.
[0074] Step 420: According to the number of cloud hosts requested to be reserved in the resource reservation request and the cloud host specifications, schedule the cloud host resources requested to be reserved in the host cluster, and d...
