As shown in fig. 3, the method is applied to a network management layer, and includes:

step 301, obtaining a target corresponding relation between the virtual local area network and a service container included under the tenant.

A Virtual Local Area Network (VLAN) is a technology that logically divides Local Area Network (LAN) devices into Network segments or smaller LANs, so as to implement data exchange of Virtual workgroups (units). The virtual local area network is mainly applied to switches and routers, but not all switches have the function, and only more than three layers of switches have the function. The network management layer in the scheme may include a virtual switch, which is used to construct a virtual network by adopting an Overlay technology on the basis of an underlay network, and to divide the virtual network into different virtual local area networks.

The Overlay technology is to construct a virtual network on top of the existing physical network, and the upper layer application is only related to the virtual network. The Underlay can be a distributed network without a central control node, and all devices in the network learn the reachable information of the network in a protocol transmission mode, and each device determines how to forward the reachable information, so that the flow cannot be regulated and controlled from the perspective of the whole network.

The number of the tenants in the embodiment of the present disclosure may be multiple, and the system belongs to a multi-tenant system, and the multi-tenant system is used to discuss and implement how to share the same system, program component, or resource in a multi-user environment, and still can ensure isolation of data between users. The division of the tenants can be divided according to actual business projects, for example, the tenants can include at least one of development tenants, production tenants, test tenants and the like, and the development tenants can also include pre-development tenants and formal development tenants. Furthermore, each tenant can also divide a plurality of service containers, and the service containers can be divided based on service information, that is, based on specific service information of a service project corresponding to the current tenant. Illustratively, as shown in fig. 2, the service container under each tenant may include a service registration and discovery component (Eureka), a service configuration (Config), a service load balancing (Ribbon), a service fusing (Hystrix), a service consumption (Feign), and the like, which are only examples and are not specific limitations of the service container.

The target corresponding relation refers to a binding relation between virtual local area networks and service containers, wherein one service container corresponds to a plurality of virtual machines in one virtual local area network, and the plurality of virtual machines corresponding to one virtual local area network are respectively distributed on different physical machines. Specifically, the network management layer may obtain a target correspondence between a virtual local area network established in advance and a service container included under the tenant.

Step 302, establishing network connection between each virtual local area network and the corresponding service container through the Calico network and the target corresponding relation.

Calico is a pure three-layer data center network scheme, and a Paas cloud architecture is seamlessly integrated, which can provide communication among controllable Virtual Machines (VMs), containers and bare machines, all data packets find corresponding hosts and containers in a routing form, and then all routes are synchronized to all machines or data centers through a Border Gateway Protocol (BGP) Protocol, thereby completing interconnection of the whole network.

In the embodiment of the present disclosure, establishing network connections between each virtual local area network and the corresponding service containers through the Calico network and the target corresponding relationship may include: and establishing network connection between each virtual local area network and the corresponding service container thereof based on the IPIP mode of the Calico network and the target corresponding relation. The network management layer can adopt an IPIP mode of Calico, an IP data packet is sleeved in the IP data packet, namely the IP layer is encapsulated into a channel (tunnel) of the IP layer, the effect of the tunnel is basically equivalent to a network bridge based on the IP layer, the tunnel is made through the routes at two ends, two originally blind networks are connected through point-to-point, and the network connection relation between the virtual local area network and a corresponding service container is established according to the target corresponding relation. After Calico is deployed in the ip mode, a network card device including a tunnel interface (tunl) is provided on a node, and is used for performing tunnel encapsulation, and the network card device is a network in an overlay mode.

In some embodiments, the resource management method may further include: and establishing network connection between the first virtual local area network and the second virtual local area network based on the Calico network.

The first virtual local area network and the second virtual local area network are any two virtual local area networks in the resource management system, which need to establish communication, and are not limited specifically. In the scheme, the network management layer adopts the Calico network to establish network connection between the first virtual local area network and the second virtual local area network when the service container corresponding to the first virtual local area network needs to communicate with the service container corresponding to the second virtual local area network, so as to realize communication between the two corresponding service containers. The network policy management by the Calico network not only can realize the management of the virtual local area network layer and the environment network layer, but also can flexibly establish communication when needed, thereby improving the flexibility of network management and resource management and the expansibility.

The resource management method provided by the embodiment of the disclosure solves the problem that a cloud management platform is unreasonably planned in a multi-tenant resource layer on the basis of the resource management system, and improves isolation performance and expansion performance on the basis of relatively improving availability guarantee of resources of service containers under each tenant through standard design from a resource and network layer, thereby improving the value of the platform. The method and the system meet the requirements of various networks, basic resources, tenant management and policy management on scene availability and intensive management, and can be applied to various complex service demand scenes.
