Description

System and method for integrating multi-cloud application services

The present invention relates to a multi-cloud application service integration technology, and more specifically, a system and method for integrating multi-cloud application services.

Generally speaking, there are multiple private clouds or public clouds in a multi-cloud cloud architecture, and each cloud has a service module to provide various services, but if you want to use various services of the multi-cloud at the same time, you must first establish communication between the multi-clouds connection.

However, it is difficult to directly establish a communication connection between multiple clouds (such as private clouds and public clouds) due to the penetration of network NAT (Network Address Translation). Furthermore, although the existing technology uses dedicated lines to establish a network architecture between multiple clouds (such as private clouds and public clouds), this technology is more complicated and difficult to manage. Therefore, how to provide a technology that can establish communication connections between multiple clouds or integrate multi-cloud application services that is easy to manage has become a major research topic for those skilled in the art.

The present invention provides a system and method for integrating multi-cloud application services that can establish communication connections between multiple clouds or are easy to manage.

The integrated multi-cloud application service system of the present invention is applied to all have service modules In the architecture of the first cloud and at least one second cloud, the system includes an active management network agent module, a central control module, and a message center module. The active management network proxy module is set in the first cloud and the second cloud corresponding to the service module, and is used for sending registration messages and intercepting network request messages sent by the corresponding service modules. The central control module is set in the first cloud to receive registration messages from the active management network agent module and record the routing information of the service module, and the central control module detects whether it can be actively managed The network agent module establishes a two-way channel. If a two-way channel can be established, the central control module and the active management network agent module establish a two-way channel, and through the central control module will include the routing information of all service modules. A message is sent to all active management network agent modules. The message center module communicates with the central control module, and the active management network agent module establishes a one-way channel with the message center module to subscribe to the message center module. When the central control module cannot communicate with the active When a two-way channel is established by the management network proxy module, the active management network proxy module forwards network request messages to the message center module.

In an embodiment of this system, the active management network agent module further detects whether the routing information of the service module has changed, and if the routing information of the service module changes, the active management network agent module resends Register the message to the central control module.

In an embodiment of this system, the central control module further detects whether it has received the registration message re-sent by the active management network agent module. If the registration message is received, the central control module will include all changes The second message of the routing information is sent to all active management network agent modules.

In an embodiment of this system, the service module includes the service module of the sender and the service module of the destination, and the network request message sent by the service module of the sender includes the network of the service module of the destination. The global domain name of the domain, and the active management network proxy module intercepts the network request message sent by the service module of the sender to forward the network request message according to the global domain name The service module to the destination.

In an embodiment of this system, the second cloud is connected to the first cloud through a NAT (Network Address Translation) network environment.

The present invention also provides a method for integrating multi-cloud application services, which is applied to a first cloud and at least one second cloud architecture that both have service modules. The method includes: setting an active management network proxy module to the corresponding first cloud Service modules in both the first cloud and the second cloud; intercept the network request messages sent by the corresponding service module through the active management network proxy module; through the active management network proxy module and message center module The group establishes a one-way channel to subscribe to the message center module; sends registration messages to the central control module through the active management network proxy module; receives registration messages through the central control module and records the routing information of the service module; The central control module detects whether it can establish a two-way channel with the active management network agent module. If a two-way channel cannot be established, the active management network agent module forwards the network request message to the message center module. To establish a two-way channel, a two-way channel is established through the central control module and the active management network agent module; and the first message including the routing information of all service modules is sent to all active management networks through the central control module Proxy module.

In an embodiment of this method, the method for integrating multi-cloud application services further includes detecting whether the routing information of the service module has changed through the active management of the network agent module, and repeating this if the routing information of the service module has not changed step.

In an embodiment of this method, in the step of detecting whether the routing information of the service module has changed through the active management network proxy module, if the routing information of the service module has changed, it returns to the active management The network agent module sends the registration message to the central control module.

In an embodiment of this method, the service module includes the service module of the sender and the service module of the destination, and the network request message sent by the service module of the sender includes the destination The full domain name of the service module on the end, and the active management network proxy module intercepts the network request message sent by the service module on the sending end, and forwards the network request message to the destination based on the domain name Service module.

In an embodiment of this method, the second cloud is connected to the first cloud through a NAT (Network Address Translation) network environment.

In the system and method for integrating multi-cloud application services of the present invention, the registration message is sent through the active management network proxy module, the message center module is subscribed to the message, and the network request message sent by the corresponding service module is intercepted. The central control module receives the registration message and records the routing information of the service module, and detects whether the central control module can establish a two-way channel with the active management network agent module. If a two-way channel can be established, the central control module sends the first message including the routing information of all service modules to all active management network agent modules. If a two-way channel cannot be established, the active management network agent module forwards the network request message to the message center module. In other words, even if there is a NAT (Network Address Translation) network environment between multiple clouds (the first cloud and the second cloud) and the two-way channel cannot be established, the active management network proxy module can also forward the network Request messages to the message center module to facilitate the establishment of a communication connection between multiple clouds in various situations.

In addition, if the routing information of the service module is changed, the registration message can also be re-sent to the central control module through the active management network proxy module to update the routing information. The service module under this architecture If you need to communicate with other service modules, you only need to use the fixed global domain name of the service module as the communication address. If the network address of the service module is changed, there is no need to change the service module itself. Routing settings allow the service module to focus on the functions of the service itself without worrying about handling routing issues.

FIG. 3 is another flowchart of the method for integrating multi-cloud application services of the present invention.

The following specific examples illustrate the implementation of the present invention. Those familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied by other different specific embodiments, and various details in this specification can also be based on different viewpoints and applications, and various modifications and changes can be made without departing from the spirit of the present invention.

Figure 1 is a schematic diagram of the architecture of the system for integrating multi-cloud application services of the present invention. As shown in the figure, the system for integrating multi-cloud application services of the present invention is applied to a first cloud 1 with a service module 10, a second cloud 2 with service modules 20a and 20b, and a second cloud with a service module 30 In the architecture of Cloud 3. The embodiment in Figure 1 takes two second clouds 2 and 3 as an example, but in other embodiments there may be one second cloud or more (for example, more than three) second clouds. Similarly, the first cloud 1 or each of the second clouds 2 and 3 may also have one service module or more service modules, and the present invention is not limited herein. In a preferred embodiment, the first cloud 1 can be selected from all clouds that can be connected, the first cloud 1, the second cloud 2, and 3 can include a private cloud or a public cloud, and the first cloud 1, the second cloud Clouds 2 and 3 can be homogeneous clouds (that is, all private clouds or public clouds) or heterogeneous clouds (that is, partly private clouds and partly public clouds).

The system for integrating multi-cloud application services includes active management network agent modules 11, 21a, 21b, 31, central control module 12, message center module 13 and other modules. The aforementioned modules can be implemented by software or hardware, for example by the cloud (first cloud 1 or second cloud 2, 3) The physical host or virtual host provides an application programming interface (API) to achieve this, but it is not limited to this.

The active management network proxy modules 11, 21a, 21b, and 31 are corresponding to the service modules 10, 20a, 20b, and 30 and are set in the first cloud 1 and the second cloud 2, 3 to intercept the corresponding service modules Groups 10, 20a, 20b, 30 send network request messages, and actively manage network proxy modules 11, 21a, 21b, 31 are also used to send related information including service modules 10, 20a, 20b, 30 And routing information registration message.

The central control module 12 is set in the first cloud 1 to receive registration messages from the active management network agent modules 11, 21a, 21b, 31, and to record the related information of the service modules 10, 20a, 20b, 30 Information and routing information. The central control module 12 is also used to detect whether it can establish a two-way channel C2 with the active management network agent modules 11, 21a, 21b, 31, if it can establish a two-way channel C2, such as the service module in Figure 1 10, 20a, 20b, the central control module 12 and the active management network agent modules 11, 21a, 21b, 31 establish a two-way channel C2, and will include the routing information of all service modules 10, 20a, 20b The first message of is sent to all active management network agent modules 11, 21a, 21b through the two-way channel C2.

The message center module 13 is in communication connection with the central control module 12. In the embodiment shown in FIG. 1, the message center module 13 is arranged in the same first cloud 1 as the central control module 12. However, in other embodiments, the message center module 13 can also be arranged in a cloud that can be connected to all clouds, and the present invention is not limited herein. The active management network agent modules 11, 21a, 21b, 31 can establish a one-way channel C1 with the message center module 13 to subscribe to the message center module 13.

When the central control module 12 cannot establish a bidirectional channel C2 with the active management network agent module 31, such as the situation of the service module 30 in Figure 1, the active management network agent module 31 forwards the network request message To the message center module 13.

For example, take the service module 20a as the sending end service module and use The service module 10 is used as the service module of the destination. The network request message sent by the service module 20a of the sending end includes the global domain name of the service module 10 of the destination. The network proxy module 21a is actively managed. It intercepts the network request message sent by the service module 20a of the sending end, and queries the routing method in the latest routing information through the global domain name of the service module 10 of the destination end, and actively manages the network proxy module 21a This routing method will be used to forward the intercepted network request message to the active management network proxy 11. After the active management network proxy module 11 receives it, it will forward the network request message to the destination based on the domain name The end of the service module 10, thereby completing the communication connection.

When the communication between the multi-cloud (first cloud 1 and second cloud 2, 3) has problems such as a NAT (Network Address Translation) network environment, for example, the service module 20a is used as the service module of the sender and The service module 30 serves as the service module of the destination. The network request message sent by the service module 20a of the sender includes the domain name of the service module 30 of the destination, and the network proxy module 21a is actively managed. It intercepts the network request message sent by the service module 20a of the sending end, and queries the routing method in the latest routing information through the global domain name of the service module 10 of the destination end, and knows the service module 10 of the destination end The routing method needs to be through the message center module 13, and the active management network agent module 21a forwards the network request message to the message center module 13 to provide active management of the channels subscribed by the network agent module 31. The management network agent module 31 can obtain the network request message from the message center module 13, and then forward the network request message to the service module 30 of the destination terminal according to the global domain name after receiving it, thereby completing the communication connection.

In one embodiment, the active management network proxy modules 11, 21a, 21b, 31 are also used to detect whether the routing information of the service modules 10, 20a, 20b, 30 has changed. If the service modules 10, 20a, If the routing information of 20b, 30 is changed, the active management network proxy module 11, 21a, 21b, 31 resends the registration message to the central control module 12.

In one embodiment, the central control module 12 is also used to detect whether the master Active management of the registration messages re-sent by the network agent modules 11, 21a, 21b, 31. If a registration message is received, the central control module 12 will send the second message including all the changed routing information to all active Manage network agent modules 11, 21a, 21b, 31.

In other words, through the integrated multi-cloud application service system of the present invention, if the service modules 10, 20a, 20b, 30 need to communicate with the remote service modules, they only need to use the fixed global domain name as the communication address. can. If the network address of the remote service module is changed, there is no need to change the routing setting of the service module 10, 20a, 20b, 30 itself, so that the service module 10, 20a, 20b, 30 can focus on the function of the service itself Without worrying about handling routing issues.

In one embodiment, the second cloud 3 is connected to the first cloud 1 or other second clouds 2 through a NAT (Network Address Translation) network environment 34. For example, the second cloud 3 may be a private cloud, and the second cloud 2 may be a public cloud, or vice versa. In this case, the active management network proxy module 31 forwards the network request message to the message center module 13.

Figure 2 is a schematic flow chart of the method for integrating multi-cloud application services of the present invention, especially for the operation mode of the active management network agent module. As shown in the figure, this method of integrating multi-cloud application services can be applied to a first cloud and at least one second cloud architecture both having service modules, and includes the following steps S10 to S19.

In step S10, the active management network proxy module is set to correspond to the service modules in both the first cloud and the second cloud.

In step S11, the network request message sent by the corresponding service module is intercepted through the active management network proxy module.

In step S12, a one-way channel is established through the active management network agent module and the message center module to subscribe to the message center module.

In step S13, a registration message is sent to the central control module through the active management network agent module.

In step S14, the registration message is received through the central control module and the related information and routing information of the service module are recorded.

In step S15, it is detected through the central control module whether it can establish a two-way channel with the active management network agent module? If the bidirectional channel cannot be established, proceed to step S16; otherwise, if the bidirectional channel can be established, proceed to step S17.

In step S16, the active management network agent module forwards the network request message to the message center module.

In step S17, a two-way channel is established through the central control module and the active management network agent module.

In step S18, a first message including routing information of all service modules is sent to all active management network agent modules through the central control module.

In the above step S15, the method of establishing a communication connection is determined according to the communication status between the first cloud and the second cloud, etc. If a two-way channel can be established, the multi-cloud (first cloud and the second cloud) can be established through steps S16 to 17 The communication connection between the two clouds); and if there is a problem with the NAT (Network Address Translation) network environment, then through step S16, use the active management network proxy module and the message center module to establish a cloudy (second The communication connection between the first cloud and the second cloud.

In step S19, detect whether the routing information of the service module has changed through the active management network proxy module, and if the routing information of the service module has not changed, repeat this step.

FIG. 3 is another flow diagram of the method of integrating multi-cloud application services of the present invention, especially the operation mode of the central control module is described. As shown in the figure, the method for integrating multi-cloud application services may further include the following steps S20 to S26.

In step S20, the central control module receives the registration information of the active management network agent module and records the routing information of the service module.

In step S21, the central control module actively sends a request to check whether it can Establish a two-way channel with the active management network proxy module? If a bidirectional channel can be established, proceed to step S22; otherwise, if a bidirectional channel cannot be established, proceed to step S26.

In step S22, the central control module responds that the active management network agent module can establish a two-way channel so that the central control module and the active management network agent module can later transmit messages. At the same time, after the active management network agent module receives this message, it starts to establish a two-way channel with the central control module.

In step S23, after the establishment of the two-way channel is completed, the active management network agent module can receive or actively query the routing information of all service modules sent by the central control module through this channel. At the same time, the central control module can also update routing information to all other registered service modules, so other service modules will also know the routing method of newly registered (registered) service modules.

In step S24, the active management network agent module periodically checks whether the routing information of the service module it is responsible for has changed? If the routing information of the service module has changed, step S25 is performed; otherwise, if the routing information of the service module has not changed, step S24 is repeated to periodically detect the routing information of the service module.

In step S25, if the routing information of the service module is changed, update or re-register the changed routing information to the central control module.

In step S26, the central control module periodically publishes the routing information of each service module to the message center module. That is, the central control module can periodically detect the routing information of all registered service modules and update the latest routing information to all service modules.

In summary, in the system and method for integrating multi-cloud application services of the present invention, the registration message is sent through the active management network proxy module, the message center module subscribes to the message, and the network sent by the corresponding service module is intercepted. Road request message. The central control module receives registration messages and records the routing information of the service module, and detects whether the central control module can be actively managed The network proxy module establishes a two-way channel. If a two-way channel can be established, the central control module sends the first message including the routing information of all service modules to all active management network agent modules. If a two-way channel cannot be established, the active management network agent module forwards the network request message to the message center module. In other words, even if there is a NAT (Network Address Translation) network environment between multiple clouds (the first cloud and the second cloud) and the two-way channel cannot be established, the active management network proxy module can also forward the network Request messages to the message center module to facilitate the establishment of a communication connection between multiple clouds in various situations.

In addition, if the routing information of the service module is changed, the registration message can also be re-sent to the central control module through the active management network proxy module to update the routing information. The service module under this architecture If you need to communicate with other service modules, you only need to use the fixed global domain name of the service module as the communication address. If the network address of the service module is changed, there is no need to change the service module itself. Routing settings allow the service module to focus on the functions of the service itself without worrying about handling routing issues.
