[0061] To make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0062] Embodiment 1

[0063] In one embodiment, as Figure 1 shown, a method for creating a cloud host is provided, which is applied to a cloud management platform. The method includes:

[0064] In response to receiving a cloud host creation instruction, obtain the cloud host configuration parameters in the cloud host creation instruction, as well as the first cluster list and the basic network list of the cloud management platform. Among them, the cloud host configuration parameters include the IP address and subnet mask of at least one cloud host to be created;

[0065] Filter the basic network list according to the IP address and subnet mask to obtain an available network list, and obtain a first host list corresponding to the available network list according to the correspondence between the network and the host;

[0066] Filter the first cluster list through the first host list to obtain a second cluster list, and obtain at least one storage pool corresponding to the hosts in the second cluster list according to the correspondence between the host and the storage pool;

[0067] Determine a target storage pool from at least one storage pool, and obtain a second host list corresponding to the target storage pool according to the correspondence between the storage pool and the host, and obtain a third cluster list corresponding to the second host list according to the correspondence between the host and the cluster;

[0068] Obtain a fourth cluster list by taking the intersection of the second cluster list and the third cluster list, and determine a target cluster from the fourth cluster list;

[0069] Determine a target host according to the second host list and the target cluster, and create at least one cloud host to be created according to the available network list, the target storage pool, the target cluster and the target host.

[0070] In a specific embodiment, when creating at least one cloud host to be created according to the available network list, directly randomly select an available network from the available network list and set it on the cloud host network card.

[0071] The first cluster list includes all clusters in the staff management platform. Through the site ID, the basic network created or managed by the site on the cloud management platform can be obtained, and the basic network list can be obtained. A site can create multiple basic networks on the cloud management platform, that is, site: basic network = 1: n. The cloud management platform uses the network ID through RPC (Remote Procedure Call) to obtain the virtual switch corresponding to the network on the corresponding site. Generally speaking, the virtual switch is built on all hosts in the same cluster, that is, virtual switch: network = 1: n; virtual switch: host = n: n; cluster: host = 1: n; storage pool: host = n: n.

[0072] Specifically, according to the corresponding relationship between the network and the host, the corresponding relationship between the host and the storage pool, and the corresponding relationship between the host and the cluster, combined with the IP address and subnet mask of the cloud host to be created, as well as the first cluster list and basic network list of the cloud management platform, the available network list, the target storage pool, the target cluster, and the target host are determined; according to the available network list, the target storage pool, the target cluster, and the target host, the cloud host to be created is created. It realizes the efficient and convenient creation of cloud hosts and improves the high availability of cloud hosts.

[0073] In one embodiment, as Figure 2 shown, the cloud host configuration parameters include the target storage pool capacity of at least one cloud host to be created. Determining the target storage pool from at least one storage pool includes:

[0074] Obtain the number of cloud hosts already allocated on at least one storage pool, and sort at least one storage pool in descending order according to the number of cloud hosts already allocated to obtain the first sorting result;

[0075] Calculate the thick-provisioned capacity and thin-provisioned capacity of at least one storage pool in turn according to the first sorting result, and compare the target storage pool capacity with the thick-provisioned capacity and thin-provisioned capacity until the target storage pool is determined.

[0076] In a specific embodiment, the storage pool is divided into at least one storage group, and <storage group, storage pool list> is obtained by traversing, where storage group: storage pool = 1: n.

[0077] Specifically, the target storage pool is determined according to the size relationship between the target storage pool capacity and the thick-provisioned capacity and thin-provisioned capacity, as well as the number of cloud hosts already allocated on the storage pool, which not only ensures that the target storage pool meets the target storage pool capacity of the cloud host to be created, but also improves the resource utilization rate of the target storage pool.

[0078] In one embodiment, as Figure 2 shown, calculating the thick-provisioned capacity and thin-provisioned capacity of at least one storage pool includes:

[0079] Obtain the total available capacity, reserved capacity, and used capacity of at least one storage pool. The thick-provisioned capacity = total available capacity - reserved capacity - used capacity;

[0080] Obtain the overcommit ratio of at least one storage pool. The thin-provisioned capacity = (total available capacity - reserved capacity) * overcommit ratio - used capacity.

[0081] Specifically, by calculating the thick-provisioned capacity and the thin-provisioned capacity, the resource utilization rate of the storage pool is improved.

[0082] In one embodiment, as Figure 2 shown, compare the target storage pool capacity with the thick-provisioned capacity and the thin-provisioned capacity until the target storage pool is determined, including:

[0083] Compare the target storage pool capacity of at least one storage pool with the thick-provisioned capacity in sequence according to the first sorting result to obtain the first capacity comparison result;

[0084] In response to the first capacity comparison result indicating that the target storage pool capacity is greater than the thick-provisioned capacity, compare the target storage pool capacity of the next storage pool with the thick-provisioned capacity;

[0085] In response to the first capacity comparison result indicating that the target storage pool capacity is less than or equal to the thick-provisioned capacity, compare the target storage pool capacity of the current storage pool with the thin-provisioned capacity to obtain the second capacity comparison result;

[0086] In response to the second capacity comparison result indicating that the target storage pool capacity is less than or equal to the thin-provisioned capacity, determine the current storage pool as the thick-provisioned storage pool, and use the current storage pool as the target storage pool, and stop the calculation and comparison;

[0087] In response to the second capacity comparison result indicating that the target storage pool capacity is greater than the thin-provisioned capacity, determine the current storage pool as the thin-provisioned storage pool, and sequentially determine whether the storage pools behind the current storage pool are thick-provisioned storage pools according to the first sorting result;

[0088] In response to the existence of a thick-provisioned storage pool behind the current storage pool, determine the corresponding thick-provisioned storage pool as the target storage pool, and stop the judgment;

[0089] In response to the non-existence of a thick-provisioned storage pool behind the current storage pool, determine the current storage pool as the target storage pool.

[0090] In a specific embodiment, when there is neither a thick-provisioned storage pool nor a thin-provisioned storage pool in at least one storage pool, prompt that the storage resources required for creating the to-be-created cloud host are missing.

[0091] Specifically, first determine whether the capacity of the target storage pool is less than or equal to the thick-provisioned capacity. If so, then determine whether the capacity of the target storage pool is less than or equal to the thin-provisioned capacity. If so, determine that the current storage pool is a thick-provisioned storage pool; if not, determine that the current storage pool is a thin-provisioned storage pool. Determine the first thick-provisioned storage pool as the target storage pool according to the first sorting result. If there is no thick-provisioned storage pool, determine the first thin-provisioned storage pool as the target storage pool. This improves the high availability of cloud hosts.

[0092] In one embodiment, as Figure 3 shown, determining a target cluster from a fourth cluster list includes:

[0093] Obtain the target application attributes of at least one cloud host to be created, and obtain the number of cloud hosts with the target application attributes in the clusters in the fourth cluster list;

[0094] Sort the clusters in the fourth cluster list in ascending order according to the number of cloud hosts with the target application attributes to obtain a second sorting result;

[0095] According to the second sorting result, take the first cluster as the target cluster.

[0096] Specifically, dispersing cloud hosts belonging to the same application attribute in different clusters ensures the balanced distribution of resources, improves the robustness of the enterprise's external application deployment, and enhances the core competitiveness of the product.

[0097] In one embodiment, as Figure 4 shown, determining a target host according to a second host list and a target cluster includes:

[0098] Obtain the hosts in the second host list and the hosts in the target cluster;

[0099] By taking the intersection of the hosts in the second host list and the hosts in the target cluster, obtain at least one available host;

[0100] Determine a target host from at least one available host.

[0101] Specifically, by taking the intersection of the hosts in the second host list and the hosts in the target cluster, it is ensured that the target host meets the storage requirements and network requirements.

[0102] In one embodiment, as Figure 4 shown, determining a target host from at least one available host includes:

[0103] Obtain the processor overcommit ratio, memory overcommit ratio, and virtual switch quantity of at least one available host;

[0104] Obtain an adjustment coefficient, and calculate the resource free space of at least one available host according to the processor overcommit ratio, memory overcommit ratio, number of virtual switches, and the adjustment coefficient, where the resource free space = (2 - processor overcommit ratio - memory overcommit ratio) / 2 - adjustment coefficient * number of virtual switches;

[0105] Sort at least one available host in descending order according to the resource free space to obtain a third sorting result;

[0106] According to the third sorting result, determine the first available host as the target host.

[0107] Specifically, by calculating the resource free space of at least one available host and determining the available host with the highest resource free space as the target host, the resource utilization rate of the host and the high availability of the cloud host are improved.

[0108] In one embodiment, before creating at least one cloud host to be created, the method further includes:

[0109] Obtain the memory parameters, processor parameters of the target cluster, and the memory parameters of the target host, where the memory parameters of the target cluster include the cluster reserved memory and the cluster used memory, the processor parameters of the target cluster include the total physical frequency of the processor, the used frequency of the processor, and the reserved frequency of the processor, and the memory parameters of the target host include the total host memory, the host memory overcommit ratio, and the used host memory;

[0110] Judge whether the memory parameters, processor parameters of the target cluster, and the memory parameters of the target host meet the boot conditions, where the boot conditions include the cluster memory boot condition, the processor boot condition, and the host memory boot condition;

[0111] In response to the memory parameters, processor parameters of the target cluster, and the memory parameters of the target host meeting the boot conditions, create at least one cloud host to be created according to the available network list, target storage pool, target cluster, and target host;

[0112] In response to the memory parameters of the target cluster not meeting the cluster memory boot condition and / or the processor parameters not meeting the processor boot condition and / or the memory parameters of the target host not meeting the host memory boot condition, re-determine the available network list, target storage pool, target cluster, and target host.

[0113] Specifically, judge whether the current resource allocation meets the boot conditions. If it meets, create the cloud host to be created according to the current resource allocation method. If it does not meet, re-determine the resource allocation method on the basis of meeting the boot conditions, where the resource allocation method includes the available network list, target storage pool, target cluster, and target host. This ensures the normal boot of the cloud host to be created.

[0114] In a specific embodiment, when customers have some special requirements, manual configuration adjustment can also be used. For example, due to network reasons or small scale, if it is required that all cloud host resources be deployed in the same cluster or the same storage, the user can adjust the entire allocation policy by himself. For example, adjust the size, location or allocation policy of the disk, the location of the cluster, and the location of the host, etc.

[0115] In a specific embodiment, it is assumed that at the beginning of batch creation of cloud hosts, 100G is found remaining in the database. The first cloud host has been allocated 8G of memory, but since this is allocated resources, the allocated 8G has not been written into the database. Therefore, when allocating the second cloud host, only 92G is available, and the allocated 8G of memory is recorded in the cache system. After all cloud hosts are allocated, the resource consumption is written into the database. The cache system contains caches of all resource capacities, such as memory and disk capacity.

[0116] It should be understood that although Figure 1 , Figure 2 , Figure 3 , Figure 4 the steps in the flowchart of Figure 1 , Figure 2 , Figure 3 , Figure 4 are shown in sequence according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless there is a clear indication in this article, the execution of these steps has no strict order limit, and these steps can be executed in other orders. Moreover,
