本申请涉及存储领域，更具体地，涉及一种管理物理主机的方法及装置。The present application relates to the field of storage, and more specifically, to a method and device for managing a physical host.
背景技术Background technique
随着云计算的不断成熟，越来越多的企业应用开始上云，由于各个企业应用对安全、稳定等能力存在特殊述求，导致公有云中存在不同形态的资源专属、安全隔离技术。With the continuous maturity of cloud computing, more and more enterprise applications have begun to migrate to the cloud. Because each enterprise application has special requirements for security and stability, there are different forms of resource-specific and security isolation technologies in the public cloud.
租户资源隔离技术是云资源逻辑隔离，但是这些租户的云资源仍然混合部署在相同的物理资源上，部署在同一台物理主机上的不同租户间虚拟机，会发生对物理主机上资源的争抢，导致这台物理主机上虚拟机性能下降。因此无法满足一些用户关于物理资源独享的述求。Tenant resource isolation technology is the logical isolation of cloud resources, but the cloud resources of these tenants are still mixed and deployed on the same physical resources, and virtual machines between different tenants deployed on the same physical host will compete for resources on the physical host , causing the performance of the virtual machine on this physical host to degrade. Therefore, it is impossible to meet the requirements of some users about the exclusive use of physical resources.
专属主机资源隔离是可以做到不同租户的虚拟机部署在不同的物理主机上，不同租户间虚拟机不会抢占物理资源。但是不同租户的相同类型专属主机是部署在相同的主机集群内，资源的超配比率是统一配置的，不能按租户独立配置。且专属主机上的虚拟机不支持高可用(High Availbility，HA)、反亲和策略部署。Dedicated host resource isolation means that virtual machines of different tenants can be deployed on different physical hosts, and virtual machines of different tenants will not seize physical resources. However, the same type of dedicated hosts of different tenants are deployed in the same host cluster, and the over-allocation ratio of resources is uniformly configured and cannot be configured independently for each tenant. And the virtual machine on the dedicated host does not support high availability (High Availability, HA), anti-affinity policy deployment.
因此，需要一种资源隔离技术，以使能够为租户独立配置资源的超配比。Therefore, there is a need for a resource isolation technique to enable the over-provisioning of resources to be independently configured for tenants.

具体实施方式Detailed ways
下面将结合附图，对本申请中的技术方案进行描述。The technical solution in this application will be described below with reference to the accompanying drawings.
图1是本申请实施例的系统架构的示意性框图。Fig. 1 is a schematic block diagram of a system architecture of an embodiment of the present application.
如图1所示，该系统中的设备包括专属云(即，第一物理主机集合的一例)、虚拟机，还可以包括多租户共享主机、专属主机。在本申请实施例中，用三角形、方形和圆形分别表示不同的租户。As shown in FIG. 1 , devices in the system include a dedicated cloud (that is, an example of the first set of physical hosts), virtual machines, and may also include multi-tenant shared hosts and dedicated hosts. In this embodiment of the application, triangles, squares and circles are used to represent different tenants respectively.
本申请实施例可以适用于租户向公共资源池申请物理主机用于进行业务处理的场景。公共资源池中包括多个物理主机，用于为不同的租户提供服务。The embodiment of the present application may be applicable to a scenario where a tenant applies for a physical host from a public resource pool for business processing. The public resource pool includes multiple physical hosts to provide services for different tenants.
物理主机可以为租户进行业务处理，例如，创建虚拟机、创建云硬盘存储数据等。在本申请实施例中，以为租户创建虚拟机为例进行说明。Physical hosts can perform business processing for tenants, for example, create virtual machines, create cloud disks to store data, and so on. In this embodiment of the application, it is described as an example to create a virtual machine for a tenant.
下面对上述设备分别进行说明。The above-mentioned devices will be described respectively below.
1、多租户共享主机1. Multi-tenant shared hosting
多租户共享主机，即，多租户共享一台物理主机。如图所示，不同形状代表不同租户，不同租户创建的虚拟机不同，不同租户间不可见彼此的虚机，但是不同租户的虚拟机是可以部署在相同的物理主机上，即一台物理主机运行着多种形状的虚拟机。其中，租户是指在云计算环境中，通过云计算服务接口使用云计算提供的各类资源的用户。Multi-tenant shared host, that is, multiple tenants share a physical host. As shown in the figure, different shapes represent different tenants. Different tenants create different virtual machines. Different tenants cannot see each other's virtual machines. However, virtual machines of different tenants can be deployed on the same physical host, that is, a physical host. Virtual machines of various shapes are running. Wherein, a tenant refers to a user who uses various resources provided by cloud computing through a cloud computing service interface in a cloud computing environment.
图2示出了租户间资源隔离的示意图。如图2所示，公有云资源自身是通过项目(租户)进行资源隔离的，并且隔离的资源是云服务器、云硬盘等，租户间是逻辑间隔离，彼此间看不到云服务器、云硬盘等，但在物理资源层是不能进行隔离的。这意味着租户间的云服务器或云硬盘还是会发放到相同的物理资源上，因此存在如下问题：Fig. 2 shows a schematic diagram of resource isolation among tenants. As shown in Figure 2, public cloud resources themselves are isolated through projects (tenants), and the isolated resources are cloud servers, cloud hard disks, etc. Tenants are logically isolated, and cloud servers and cloud hard disks cannot be seen from each other. etc., but isolation cannot be performed at the physical resource layer. This means that the cloud servers or cloud hard disks between tenants will still be allocated to the same physical resources, so there are the following problems:
(1)运行在相同物理主机上的不同租户的虚拟机，对物理主机的资源存在抢占，例如其中一个租户的虚拟机运行业务导致CPU、总线IO压力大，导致物理机压力高，从而导致其他租户的虚拟机运行性能下降；(1) The virtual machines of different tenants running on the same physical host preempt the resources of the physical host. For example, one of the tenants’ virtual machines running business causes high pressure on CPU and bus IO, which leads to high pressure on the physical machine, which leads to other The running performance of the tenant's virtual machine is degraded;
(2)公共资源池资源存在超配，但租户不能对该超配系数进行调整，进而无法控制物理主机上发放云服务器的能力；(2) There is an over-allocation of resources in the public resource pool, but the tenant cannot adjust the over-allocation coefficient, and thus cannot control the ability to issue cloud servers on the physical host;
(3)在同一台物理主机上运行不同租户的虚拟机，当其中一个租户的虚拟机被攻击，其他租户的虚拟机也存在被攻击的威胁。(3) Running virtual machines of different tenants on the same physical host, when a virtual machine of one tenant is attacked, the virtual machines of other tenants may also be attacked.
因此，对于某类型的租户，例如，对业务安全性要求极高的租户，可能会在公有云资源中申请专属主机。Therefore, for certain types of tenants, for example, tenants with extremely high business security requirements, they may apply for dedicated hosts in public cloud resources.
2、专属主机2. Dedicated host
专属主机(Dedicated Host，DeH)是将一台计算主机或者物理主机专属于某个租户，只有专属主机的租户可以向该主机上发放云服务器，其他租户是不可以发放云服务器到该专属主机上的。专属主机能带来更多的可见性，能够控制实例在物理服务器上的放置方式，能够可靠地使用同一台物理服务器。专属主机资源只能专属于一个租户使用，这样可以做到与不同租户的物理资源隔离，进而避免租户间资源抢占或被攻击的风险。专属主机与公共物理主机是混合部署在一起的，所有租户的相同类型的专属主机都部署在同一个主机集群内，或者说，是在同一个公共资源池内，因此专属主机与公共物理主机是逻辑隔离的。Dedicated Host (Dedicated Host, DeH) is to dedicate a computing host or physical host to a certain tenant. Only the tenant of the dedicated host can issue cloud servers to the host, and other tenants cannot issue cloud servers to the dedicated host. of. Dedicated hosting brings more visibility, the ability to control how instances are placed on physical servers, and the ability to reliably use the same physical server. Dedicated host resources can only be used exclusively by one tenant, so that they can be isolated from the physical resources of different tenants, thereby avoiding the risk of resource preemption or attacks between tenants. Dedicated hosts and public physical hosts are mixed and deployed together. Dedicated hosts of the same type of all tenants are deployed in the same host cluster, or in the same public resource pool, so dedicated hosts and public physical hosts are logical Isolated.
图3示出了专属主机资源隔离的示意图。如图3所示，专属主机上运行的虚拟机都是相同的颜色，即专属主机上虚拟机都是同一个租户的。不同租户专属不同的计算主机，则专属主机资源在租户间是隔离的。所有相同类型的专属主机部署在同一个主机集群中，而公共主机按类型部署到公共的主机集群中。FIG. 3 shows a schematic diagram of dedicated host resource isolation. As shown in Figure 3, the virtual machines running on the dedicated host are all of the same color, that is, the virtual machines on the dedicated host belong to the same tenant. Different tenants own different computing hosts, and the dedicated host resources are isolated between tenants. All dedicated hosts of the same type are deployed in the same host cluster, while public hosts are deployed by type in a common host cluster.
由于在专属主机上创建的虚拟机是绑定物理主机的，另外物理部署上不存在特殊处理，因此存在如下问题：Since the virtual machine created on the dedicated host is bound to the physical host, and there is no special processing on the physical deployment, there are the following problems:
(1)所有的专属主机物理部署上与普通物理主机是混合在相同的机柜中，没有物理空间上的隔离，因此机柜不易管理；(1) All dedicated hosts are physically deployed in the same cabinet as common physical hosts, and there is no isolation in physical space, so the cabinets are not easy to manage;
(2)所有租户的专属主机都是部署在一个主机集群中，资源的超配比率是统一配置的，不能按租户独立配置；(2) The dedicated hosts of all tenants are deployed in a host cluster, and the resource overprovision ratio is uniformly configured and cannot be configured independently by tenants;
(3)专属主机上运行的虚拟机不能进行高可用(high availability，HA)和反亲和策略，无法保证用户业务的高可用性和稳定性。(3) Virtual machines running on dedicated hosts cannot perform high availability (HA) and anti-affinity strategies, and cannot guarantee high availability and stability of user services.
因此，本申请提出了一种专属云资源隔离的方法，在专属云资源隔离中，称专属主机为专属物理主机或专属计算主机，即，专属物理主机或专属计算主机是专属资源池中的专属主机。接下来具体描述。Therefore, this application proposes a method for isolating dedicated cloud resources. In dedicated cloud resource isolation, a dedicated host is called a dedicated physical host or a dedicated computing host, that is, a dedicated physical host or a dedicated computing host is a dedicated resource pool. host. Next, it will be described in detail.
3、专属云3. Dedicated cloud
专属云(Dedicated Cloud，DeC)，基于物理资源池的专属管理，以满足企业用户对资源专属、隔离的需求，又为企业用户提供公用云上的各种服务能力，除了云资源租赁成本，无需其他不必要的成本投入。本申请提出的专属云资源隔离，可以提供的资源专属能力有：Dedicated Cloud (Dedicated Cloud, DeC), based on the dedicated management of physical resource pools, meets the needs of enterprise users for exclusive and isolated resources, and provides enterprise users with various service capabilities on the public cloud. In addition to the cost of cloud resource leasing, there is no need Other unnecessary cost input. The dedicated cloud resource isolation proposed in this application can provide resource-specific capabilities as follows:
计算专属资源池：租户可以专属弹性云服务(elastic cloud service，ECS)和裸金属服务(bare metal service，BMS)计算资源，发放虚拟机(virtual machine，VM)到专属ECS计算主机上，而裸金属服务器则发放到专属BMS计算主机上，不同租户间计算资源不会争抢。Dedicated resource pool for computing: Tenants can dedicate elastic cloud service (elastic cloud service, ECS) and bare metal service (bare metal service, BMS) computing resources, distribute virtual machines (virtual machine, VM) to dedicated ECS computing hosts, and Metal servers are assigned to dedicated BMS computing hosts, so there will be no competition for computing resources between different tenants.
存储专属资源池：租户可以专属存储服务器资源或存储阵列设备，不同租户的应用数据保存到不同的存储服务器或存储设备上，彼此间数据不可见。Dedicated resource pool for storage: Tenants can exclusively store server resources or storage array devices, and the application data of different tenants are stored on different storage servers or storage devices, and the data is not visible to each other.
虚拟私有云(virtual private cloud，VPC)网络专属：由于基于公有云架构，物理网络与公有云网络基本一致，则由VPC网络专属进行租户流量隔离。对于要求物理网络隔离的租户，可以进行管理网络与公有云一致，数据网络单独部署的形式进行专属。Virtual private cloud (virtual private cloud, VPC) network exclusive: Since it is based on the public cloud architecture, the physical network is basically the same as the public cloud network, and the VPC network is dedicated to isolate tenant traffic. For tenants who require physical network isolation, the management network can be consistent with the public cloud, and the data network can be deployed separately.
本申请提出的专属云资源隔离是每个租户专属一个资源池，即每个租户有专属资源池(即，第一物理主机集合的一例)。该专属资源池可以理解为是从公共资源池中划分的部分资源池。该专属资源池内包含多台物理主机，每个租户的专属物理主机与公共物理主机以及专属主机是在不同的资源池，不同租户间的资源池也是各自独立的。专属云同一个资源池内的虚拟机支持HA，也可以进行反亲和策略。专属云下不仅计算资源专属，也可以集成存储和网络资源专属能力，使得的整个基础设施即服务(Infrastructure as aService，IaaS)层资源全部可以专属。The dedicated cloud resource isolation proposed in this application is that each tenant has a dedicated resource pool, that is, each tenant has a dedicated resource pool (that is, an example of the first physical host set). The dedicated resource pool can be understood as a partial resource pool divided from the public resource pool. The dedicated resource pool contains multiple physical hosts. The dedicated physical hosts of each tenant are in different resource pools from the public physical hosts and the dedicated hosts. The resource pools between different tenants are also independent. The virtual machines in the same resource pool of the dedicated cloud support HA, and anti-affinity policies can also be implemented. Under the dedicated cloud, not only computing resources are exclusive, but also storage and network resource exclusive capabilities can be integrated, so that the entire infrastructure as a service (Infrastructure as a Service, IaaS) layer resources can be exclusive.
4、专属资源池4. Exclusive resource pool
专属资源池(即，第一物理主机集合的一例)包括公共资源池中的至少一个物理主机。如前所述，本申请实施例中，专属资源池中的专属物理主机与租户进行专属映射，使得整个资源池交付给映射的专属租户在一定的时间段内专属使用。专属资源池专属于一个租户，一个租户可以对应多个专属资源池。专属资源池中的物理主机或者专属主机也可以称为专属物理主机。The dedicated resource pool (ie, an example of the first set of physical hosts) includes at least one physical host in the public resource pool. As mentioned above, in the embodiment of this application, the dedicated physical host in the dedicated resource pool is mapped exclusively to the tenant, so that the entire resource pool is delivered to the mapped dedicated tenant for exclusive use within a certain period of time. A dedicated resource pool is dedicated to one tenant, and one tenant can correspond to multiple dedicated resource pools. A physical host in a dedicated resource pool or a dedicated host may also be called a dedicated physical host.
5、专属物理主机5. Dedicated physical host
物理主机，又称为计算主机，是相对于虚拟机而言的对实体计算机的称呼。物理主机是实际存在的硬件专用独立主机，可以用来创建运行虚拟机。A physical host, also known as a computing host, is a name for a physical computer as opposed to a virtual machine. A physical host is an actual hardware-dedicated independent host that can be used to create and run virtual machines.
在本申请实施例中，称专属资源池中的物理主机为专属物理主机。专属物理主机是从公共资源池中选择的部分物理主机。专属物理主机在一定的时间内为一个租户进行业务处理。In this embodiment of the present application, the physical hosts in the dedicated resource pool are referred to as dedicated physical hosts. Dedicated physical hosts are some physical hosts selected from the public resource pool. A dedicated physical host performs business processing for a tenant within a certain period of time.
6、虚拟机6. Virtual machine
虚拟机是指通过软件模拟的具有完整硬件系统功能的、运行在一个完全隔离环境中的完整计算机系统。其中，一个物理主机通过虚拟化技术被虚拟成了多个逻辑计算机，每一个逻辑计算机即是一个虚拟机。每个虚拟机可以运行不同的操作系统，因此，各个虚拟机的应用程序可以运行在相互独立的操作系统的空间内。A virtual machine refers to a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. Wherein, a physical host is virtualized into multiple logical computers through virtualization technology, and each logical computer is a virtual machine. Each virtual machine can run a different operating system, therefore, the application programs of each virtual machine can run in spaces of independent operating systems.
需要说明的是，在本申请实施例中，一个物理主机上可以运行一个虚拟机。或者，一个物理主机上也可以运行多个虚拟机。本申请实施例对此并未作任何限定。It should be noted that, in the embodiment of the present application, one virtual machine may run on one physical host. Alternatively, multiple virtual machines can run on one physical host. The embodiment of the present application does not make any limitation on this.

具体地，如前所述，公共资源池中包括多个物理主机，该多个物理主机供多个租户进行业务处理。可选地，公共资源池中包括多个专属资源池，该专属资源池在一定的时间段内仅供一个租户使用。该一定的时间段可以是租户的业务从开始到结束的时间段；也可以是预设的时间段，例如，一年；或者，也可以是根据租户的权限配置一个时间段，本申请实施例对此不作限定。通过租户发送的主机类型信息，可以为租户分配合适的物理主机，从而不仅保障租户的业务，而且可以提高物理主机的使用率。Specifically, as mentioned above, the public resource pool includes multiple physical hosts, and the multiple physical hosts are used by multiple tenants for business processing. Optionally, the public resource pool includes multiple dedicated resource pools, and the dedicated resource pools are only used by one tenant within a certain period of time. The certain time period can be the time period from the beginning to the end of the tenant's business; it can also be a preset time period, for example, one year; or, it can also be a time period configured according to the tenant's authority. There is no limit to this. Through the host type information sent by the tenant, a suitable physical host can be allocated to the tenant, so as to not only guarantee the business of the tenant, but also improve the utilization rate of the physical host.
具体地，以租户#A请求创建虚拟机，该虚拟机用于为租户#A处理业务为例。不同业务需要的虚拟机配置类型不同，例如，对于ECS服务，不同配置类型的虚拟机，例如，分为通用计算型、高性能计算型等，不同配置类型的虚拟机对物理主机有不同的硬件配置要求。不同业务需要的裸金属服务器硬件配置也是不一样的，例如对于BMS服务，因此物理主机根据硬件配置是划分成不同类型的，主机类型就是支持创建的云服务器类型(Flavor)。租户#A基于业务需求申请至少一个物理主机，并选择物理主机的主机类型，从公共资源池中为租户#A选择至少一个物理主机，记为专属物理主机(即，第一物理主机集合中的物理主机的一例)。可选地，判断与主机类型匹配的专属资源池是否存在，若存在，则将专属物理主机加入到专属资源池中；若不存在，则先创建专属资源池，并将专属物理主机加入到专属资源池中。Specifically, take tenant #A requesting to create a virtual machine, and the virtual machine is used to process services for tenant #A as an example.

Tenant #A can apply for multiple physical hosts of the same type, or multiple physical hosts of different types. When tenant #A applies for multiple physical hosts of different types, the same type of physical hosts can be placed in a dedicated resource pool. A physical host for business processing.
应理解，由于资源池下的专属物理主机都专属于一个租户，因此该资源池也是专属于该租户的。不同的租户有各自的专属资源池，即使资源池类型相同，不同租户的专属资源池也是单独划分的。专属资源池中的专属物理主机在一定的时段内仅供租户#A进行业务处理。该一定的时段可以是业务从开始到结束的时间段，也可以是预先设定的最长期限，例如，一年期限，此处不作限定。It should be understood that since the dedicated physical hosts under the resource pool are all dedicated to a tenant, the resource pool is also dedicated to the tenant. Different tenants have their own dedicated resource pools. Even if the resource pools are of the same type, the dedicated resource pools of different tenants are divided separately. The dedicated physical hosts in the dedicated resource pool are only available to tenant #A for business processing within a certain period of time. The certain period of time may be the time period from the beginning to the end of the business, or a preset longest period, for example, a one-year period, which is not limited here.
为租户#A分配好专属物理主机后，会对专属物理主机配置标识信息，以指专属资源池中的专属物理主机在一定时段内仅用于处理租户#A的业务。After assigning a dedicated physical host to tenant #A, the dedicated physical host will be configured with identification information to indicate that the dedicated physical host in the dedicated resource pool is only used to process the business of tenant #A within a certain period of time.

可选地，获取第一指示信息，所述第一指示信息用于指示所述第一物理主机集合所对应的主机类型。Optionally, first indication information is acquired, where the first indication information is used to indicate a host type corresponding to the first set of physical hosts.
具体地，当第一物理主机集合中包括多个类型的物理主机时，可以根据该指示信息，为租户从多个类型的物理主机中确定合适类型的物理主机。Specifically, when the first set of physical hosts includes multiple types of physical hosts, an appropriate type of physical host may be determined for the tenant from the multiple types of physical hosts according to the indication information.
接下来具体说明如何根据该标识信息确定专属物理主机或专属资源池，首先介绍第一映射关系信息。Next, how to determine the dedicated physical host or the dedicated resource pool according to the identification information will be described in detail. Firstly, the first mapping relationship information will be introduced.
可选地，该标识信息包括租户#A与专属物理主机之间的第一映射关系信息。Optionally, the identification information includes first mapping relationship information between the tenant #A and the dedicated physical host.
具体地，为租户分配好专属物理主机后，后台会在数据库中保存租户与专属物理主机之间的映射关系，主要字段为租户、物理主机、主机类型。并且如前所述，将专属物理主机加入到专属资源池中，并将资源池标记为主机类型名称。如图5所示，图5示出了专属物理主机的架构图。Specifically, after assigning a dedicated physical host to a tenant, the background will save the mapping relationship between the tenant and the dedicated physical host in the database. The main fields are tenant, physical host, and host type. And as mentioned above, add the dedicated physical host to the dedicated resource pool, and mark the resource pool with the host type name. As shown in FIG. 5, FIG. 5 shows an architecture diagram of a dedicated physical host.
如图5所示，租户#A申请的物理主机有物理主机01、物理主机02、物理主机03和物理主机04，其中物理主机01和物理主机02的主机类型是类型(Flavor)1，物理主机03和物理主机04的主机类型是Flavor2；租户#B申请的物理主机有物理主机05和物理主机06，其中物理主机05和物理主机06的主机类型也是Flavor1。如前所述，不同的租户有各自的专属资源池，即使资源池类型相同，不同租户的专属资源池也是单独划分的。因此，租户#A对应两个专属资源池，分别是租户#A Flavor1资源池、租户#A Flavor2资源池；租户#B对应一个专属资源池，租户#B Flavor1资源池。换句话说，在一定的时间段内，租户#A Flavor1资源池、租户#A Flavor2资源池仅用于处理租户#A的业务；租户#B Flavor1资源池仅用于处理租户#B的业务。As shown in Figure 5, the physical hosts applied by tenant #A include physical host 01, physical host 02, physical host 03, and physical host 04, where the host types of physical host 01 and physical host 02 are type (Flavor) 1, physical host The host types of 03 and physical host 04 are Flavor2; the physical hosts applied by tenant #B include physical host 05 and physical host 06, and the host types of physical host 05 and physical host 06 are also Flavor1. As mentioned above, different tenants have their own dedicated resource pools. Even if the resource pools are of the same type, the dedicated resource pools of different tenants are divided separately. Therefore, tenant #A corresponds to two dedicated resource pools, namely tenant #A Flavor1 resource pool and tenant #A Flavor2 resource pool; tenant #B corresponds to a dedicated resource pool, tenant #B Flavor1 resource pool. In other words, within a certain period of time, the resource pool of tenant #A Flavor1 and resource pool of tenant #A Flavor2 are only used to process the business of tenant #A; the resource pool of flavor1 of tenant #B is only used to process the business of tenant #B.
通过为租户分配专属资源池，能够根据租户的业务需求，为租户独立配置资源的超配比，提高租户的用户体验。By allocating dedicated resource pools to tenants, the overprovision of resources can be independently configured for tenants according to their business needs, improving the user experience of tenants.
可选地，接收所述第一租户发送的第一业务请求信息，所述第一业务请求信息包括第一业务所需的主机类型信息；根据所述主机类型信息确定T个物理主机，根据所述主机类型信息确定T个物理主机，所述T个物理主机中包括所述第一物理主机集合中的至少一个物理主机，其中，所述T为正整数；根据所述第一映射关系信息，确定所述第一物理主机集合中为所述第一租户处理所述第一业务的物理主机。Optionally, receiving the first service request information sent by the first tenant, the first service request information including host type information required by the first service; determining T physical hosts according to the host type information, and determining T physical hosts according to the The host type information determines T physical hosts, and the T physical hosts include at least one physical host in the first physical host set, where the T is a positive integer; according to the first mapping relationship information, Determine a physical host in the first set of physical hosts that processes the first service for the first tenant.
具体地，根据主机类型信息确定T个物理主机，该T个物理主机可能包括租户#A所对应的专属资源池中的专属物理主机、公共资源池中的物理主机、其他租户所对应的物理主机等。因此，根据租户#A与专属物理主机的映射关系，从该T个物理主机中选择属于租户#A所对应的专属资源池中的专属物理主机。其中，该专属物理主机不仅是租户#A的专属物理主机，也是业务处理所需的物理主机。Specifically, T physical hosts are determined according to the host type information, and the T physical hosts may include dedicated physical hosts in the dedicated resource pool corresponding to tenant #A, physical hosts in the public resource pool, and physical hosts corresponding to other tenants Wait. Therefore, according to the mapping relationship between the tenant #A and the dedicated physical host, the dedicated physical host belonging to the dedicated resource pool corresponding to the tenant #A is selected from the T physical hosts. Wherein, the dedicated physical host is not only a dedicated physical host of tenant #A, but also a physical host required for business processing.
或者，根据主机类型信息、第一映射关系信息或第二映射关系信息可以直接确定专属物理主机。Alternatively, the dedicated physical host may be directly determined according to the host type information, the first mapping relationship information, or the second mapping relationship information.
在本申请实施例中，可以通过专属物理主机与租户之间的映射关系，控制用于处理租户业务的物理主机。图6以租户#A请求创建虚拟机为例，示出了专属物理主机的发放过程。In the embodiment of the present application, the physical host used to process tenant services can be controlled through the mapping relationship between the dedicated physical host and the tenant. FIG. 6 shows the provisioning process of a dedicated physical host by taking tenant #A's request to create a virtual machine as an example.
610，租户#A向ECS/BMS应用程序编程接口(ECS/BMS Application ProgrammingInterface，ECS/BMS API)发送创建虚拟机请求信息，且租户#A发送该请求信息时，会选择要发放的虚拟机的类型。610. Tenant #A sends request information for creating a virtual machine to the ECS/BMS Application Programming Interface (ECS/BMS Application Programming Interface, ECS/BMS API), and when tenant #A sends the request information, it will select the virtual machine to be issued type.
620，ECS/BMS API负责响应租户的各种操作请求。620. The ECS/BMS API is responsible for responding to various operation requests of the tenant.
630，ECS/BMS调度程序(ECS/BMS Scheduler)负责选择合适的物理主机来发放云服务器或创建虚拟机。ECS/BMS API接收请求后，向ECS/BMS Scheduler发消息，进行过滤物理主机。其中，Instance Flavor过滤器(Filter)过滤出与云服务器与虚拟机类型匹配的资源池，过滤出与虚拟机flavor一致的物理主机(即，T个物理主机的一例)，该物理主机中可能包括租户#A、租户#B以及公共资源池中的物理主机。再通过新增加的专属物理主机(Dedicate Compute Node)Filter根据租户#A与专属物理主机的映射关系过滤出租户#A专属的物理主机，这样从之前过滤出的相同flavor主机中过滤出当前租户#A的专属物理主机来；可选地，再通过计算资源(Compute Resource)Filter过滤出资源充足的专属物理主机。最后向选出来的专属物理主机发创建云服务器或虚拟机的消息。630. An ECS/BMS scheduler (ECS/BMS Scheduler) is responsible for selecting a suitable physical host to provision a cloud server or create a virtual machine. After receiving the request, the ECS/BMS API sends a message to the ECS/BMS Scheduler to filter the physical hosts. Among them, the Instance Flavor filter (Filter) filters out the resource pool that matches the type of the cloud server and the virtual machine, and filters out the physical host that is consistent with the flavor of the virtual machine (that is, an example of T physical hosts), which may include Tenant #A, tenant #B, and physical hosts in the common resource pool. Then use the newly added dedicated physical host (Dedicate Compute Node) Filter to filter the physical host dedicated to tenant #A according to the mapping relationship between tenant #A and dedicated physical host, so that the current tenant can be filtered from the same flavor hosts filtered out before# A’s dedicated physical host; optionally, use the Compute Resource (Compute Resource) Filter to filter out dedicated physical hosts with sufficient resources. Finally, send a message to the selected dedicated physical host to create a cloud server or virtual machine.
640，专属物理主机负责运行云服务器。专属物理主机接收到创建云服务器或虚拟机消息后，创建并启动云服务器或虚拟机。可选地，专属物理主机在创建云服务器前，需要先创建云服务器要使用的云硬盘，专属物理主机向专属存储服务(Dedicated StorageService，DSS)DSS发送创建云硬盘请求。640, the dedicated physical host is responsible for running the cloud server. After receiving the message of creating a cloud server or virtual machine, the dedicated physical host creates and starts the cloud server or virtual machine. Optionally, before creating the cloud server, the dedicated physical host needs to create a cloud hard disk to be used by the cloud server, and the dedicated physical host sends a request to create a cloud hard disk to a Dedicated Storage Service (DSS) DSS.
650，DSS服务接收到创建专属云硬盘，DSS Scheduler通过专属存储过滤器过滤选择专属存储，最后在专属存储上创建云硬盘过程。专属云中通过DSS服务管理专属存储。关于专属存储的管理模式，与专属物理主机的架构原来基本一致，也是通过租户与存储资源的映射关系进行管理的，此处不再对专属存储专属架构原理进行赘述。创建专属云硬盘的过程与虚拟机的发放过程基本相同，此处不再赘述。650, the DSS service receives the process of creating a dedicated cloud hard disk, and the DSS Scheduler filters and selects the dedicated storage through the dedicated storage filter, and finally creates a cloud hard disk on the dedicated storage. Dedicated storage is managed through the DSS service in the dedicated cloud. Regarding the management mode of dedicated storage, it is basically the same as the original architecture of dedicated physical hosts, and it is also managed through the mapping relationship between tenants and storage resources. The principle of dedicated storage dedicated architecture will not be described here. The process of creating a dedicated cloud hard disk is basically the same as the provisioning process of a virtual machine, and will not be repeated here.
660，专属物理主机等待专属云硬盘创建成功后，将专属云硬盘挂载到云服务器上，并启动云服务器。660. After the dedicated physical host waits for the dedicated cloud hard disk to be successfully created, mount the dedicated cloud hard disk to the cloud server, and start the cloud server.
基于ECS的HA触发机制，专属资源池内的云服务器故障后，也会在相同的条件下触发HA，然后重新按照以上调度流程，选择合适的专属物理主机启动故障云服务器。Based on the HA trigger mechanism of ECS, after a cloud server in the dedicated resource pool fails, HA will also be triggered under the same conditions, and then follow the above scheduling process again to select a suitable dedicated physical host to start the failed cloud server.
接下来描述第二映射关系信息。Next, the second mapping relation information is described.
可选地，该标识信息包括租户#A与专属资源池之间的第二映射关系信息。Optionally, the identification information includes second mapping relationship information between the tenant #A and the dedicated resource pool.
具体地，如前所述，租户#A申请专属物理主机时选择专属主机类型，申请成功后，后台判断与主机类型匹配的专属资源池是否存在，如果不存在，先创建专属资源池，将该资源池标记为主机类型名称，并保存租户与该专属资源池之间的映射关系，以及资源池与专属主机的映射关系保存到数据库中，再将专属物理主机加入到该资源池中，如果已存在匹配的专属资源池，则直接将专属物理主机加入到已存在的专属资源池中。Specifically, as mentioned above, tenant #A selects the dedicated host type when applying for a dedicated physical host. After the application is successful, the background judges whether a dedicated resource pool matching the host type exists. The resource pool is marked as the name of the host type, and the mapping relationship between the tenant and the dedicated resource pool, and the mapping relationship between the resource pool and the dedicated host are saved in the database, and then the dedicated physical host is added to the resource pool. If it already exists If there is a matching dedicated resource pool, the dedicated physical host will be directly added to the existing dedicated resource pool.
通过资源池与租户进行专属映射，使得整个资源池中的物理主机交付给映射的专属租户使用。如图7所示，图7示出了专属资源池的架构图。Through exclusive mapping between resource pools and tenants, the physical hosts in the entire resource pool are delivered to the mapped exclusive tenants. As shown in FIG. 7, FIG. 7 shows an architecture diagram of a dedicated resource pool.
从图7中可以看出，租户#A对应两个类型的资源池，分别是租户#A Flavor1资源池和租户#A Flavor2资源池；租户#B对应资源池类型为Flavor1的租户#B Flavor1资源池。租户#A Flavor1资源池中包括物理主机01和物理主机02，租户#A Flavor2资源池中包括物理主机03和物理主机04，这四个物理主机都是专属于租户#A的；租户#B Flavor1资源池中包括物理主机05和物理主机06，这两个物理主机都是专属于租户#B的。As can be seen from Figure 7, tenant #A corresponds to two types of resource pools, which are tenant #A Flavor1 resource pool and tenant #A Flavor2 resource pool; tenant #B corresponds to tenant #B Flavor1 resources whose resource pool type is Flavor1 pool. Tenant #A Flavor1 resource pool includes physical host 01 and physical host 02, tenant #A Flavor2 resource pool includes physical host 03 and physical host 04, these four physical hosts are exclusive to tenant #A; tenant #B Flavor1 The resource pool includes physical host 05 and physical host 06, both of which are dedicated to tenant #B.
从图7可以看出，数据库中会记录专属云租户与专属资源池的映射关系，主要字段为租户、资源池、资源池类型，另外还会保存资源池与专属计算主机的映射关系，主要字段为资源池、计算主机。As can be seen from Figure 7, the database will record the mapping relationship between dedicated cloud tenants and dedicated resource pools. The main fields are tenants, resource pools, and resource pool types. In addition, the mapping relationship between resource pools and dedicated computing hosts will be saved. The main fields These are resource pools and computing hosts.
需要说明的是，租户申请的不同类型的专属物理主机也可以放在同一个专属资源池内。It should be noted that different types of dedicated physical hosts applied by tenants can also be placed in the same dedicated resource pool.
可选地，接收所述第一租户发送的第二业务请求信息，所述第二业务请求信息包括第二业务所需的主机类型信息；根据所述主机类型信息确定M个物理主机集合，所述M个物理主机集合中包括所述第一物理主机集合，其中，所述M为正整数；根据所述第二映射关系信息，确定为所述第一租户处理所述第二业务的所述第一物理主机集合；确定所述第一物理主机集合中为所述第一租户处理所述第二业务的物理主机。Optionally, receiving the second service request information sent by the first tenant, the second service request information including host type information required by the second service; determining M physical host sets according to the host type information, the The M physical host sets include the first physical host set, wherein the M is a positive integer; according to the second mapping relationship information, it is determined that the first tenant processes the second business. A first set of physical hosts: determining a physical host in the first set of physical hosts that processes the second service for the first tenant.
具体地，根据主机类型信息确定的M个专属资源池，可能包括其他租户的专属资源池、公共资源池。故，根据映射关系从该M个专属资源池中确定租户#A对应的专属资源池，然后再从该专属资源池中确定出专属物理主机。Specifically, the M dedicated resource pools determined according to the host type information may include other tenants' dedicated resource pools and public resource pools. Therefore, the dedicated resource pool corresponding to tenant #A is determined from the M dedicated resource pools according to the mapping relationship, and then the dedicated physical host is determined from the dedicated resource pool.
可选地，所述确定所述第一物理主机集合中为所述第一租户处理第二业务的物理主机，包括：根据第三映射关系信息，确定所述第一物理主机集合中为所述第一租户处理第二业务的物理主机，其中，所述第三映射关系信息是预先记录的所述第一物理主机集合与所述第一物理主机集合中各物理主机之间的映射关系信息。Optionally, the determining the physical hosts in the first set of physical hosts that process the second service for the first tenant includes: according to the third mapping relationship information, determining the physical hosts in the first set of physical hosts that are the A physical host of the first tenant processing the second service, wherein the third mapping relationship information is pre-recorded mapping relationship information between the first set of physical hosts and each physical host in the first set of physical hosts.
具体地，专属资源池中包括多个专属物理主机，该多个专属物理主机包括第一专属物理主机，该第一专属物理主机是用于处理第二业务的物理主机。如前所述，租户#A在申请专属物理主机时，会记录专属资源池与专属物理主机之间的映射关系信息，根据该映射关系信息就可以进一步确定出第一专属物理主机。例如，当专属资源池中是同种类型的专属物理主机时，根据映射关系信息确定出专属资源池中的专属物理主机，那么这些专属物理主机都是所述的第一专属物理主机。又例如，当专属资源池中不是同种类型的专属物理主机时，可以预先记录专属资源池与多种类型的专属物理主机的映射关系，该映射关系的主要字段可以为资源池、物理主机、主机类型，进一步，根据该映射关系确定第一专属物理主机。Specifically, the dedicated resource pool includes multiple dedicated physical hosts, and the multiple dedicated physical hosts include a first dedicated physical host, where the first dedicated physical host is a physical host for processing the second service.
