Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of a hybrid cloud-based request response method according to an embodiment of the present invention, where the embodiment is applicable to a case of resource management of a hybrid cloud, and the method may be executed by a hybrid cloud-based request response apparatus according to an embodiment of the present invention, where the apparatus may be implemented by software and/or hardware, and may be integrated in an electronic device for processing distributed transactions.
As shown in fig. 1, the hybrid cloud-based request response method includes:
s110, receiving a resource request of a client; and if the resource request target is a static resource, determining that the static resource accesses the domain name.
The resources accessed by the client may be static resources or dynamic resources. The static resource can be a large non-sensitive resource such as a picture and a video, and the dynamic resource can be a resource of data related to financial insurance business.
In this scheme, optionally, the static resource access domain name and the dynamic resource access domain name are set by differentiation.
According to the scheme, the domain name is accessed by separating dynamic and static services and distinguishing dynamic resources and static resources, and different paths of the Internet are accessed through the DNS server.
And S120, determining a target edge node of the public cloud with the nearest position to the resource request sending position of the client.
The edge node may be a node composed of one or more servers for providing a request response. The edge node can be used for accelerating the website and distributing the content of the source station to the node closest to the user, so that the user can obtain the required content nearby, and the response speed and success rate of the user access are improved. The method solves the problem of access delay caused by distribution, bandwidth and server performance, and is suitable for scenes such as site acceleration, on-demand broadcasting, live broadcasting and the like.
In this scheme, specifically, when a user accesses a static resource applied to a hybrid cloud deployment architecture, a DNS (Domain Name System) server may return a Content Delivery Network (CDN) edge node deployed in a global mass of a public cloud to the user nearby, and the CDN directly returns hotspot data in a cache to the user, so as to improve the user access speed.
A CDN (Content Delivery Network) is a Content Delivery Network constructed above a Network. The basic principle of CDNs is the widespread adoption of various cache servers distributed to regions or networks where user access is relatively centralized. When a user accesses a website, the access of the user is directed to the nearest cache server which works normally by using the global load technology, and the cache server directly responds to the user request, so that the access response speed and the hit rate of the user are improved. The key technologies of the CDN mainly include a content storage technology, a content delivery technology, a load balancing technology, and the like.
And S130, feeding hot spot data cached by the target edge node back to the client.
Fig. 2 is a flow chart of access to static resources deployed in a hybrid cloud according to an embodiment of the present invention, as shown in fig. 2, it can be understood that after a target edge node is determined, content currently cached by the target edge node, such as cached hotspot data, may be fed back to the client. Therefore, the problems of low loading speed, large consumption bandwidth and poor user experience are solved.
In this technical solution, optionally, after determining a target edge node of a public cloud closest to a resource request sending location of the client, the method further includes:
and if the target edge node does not have the cache data, returning the source to the public cloud flexible bandwidth network address through the private network to obtain the static resource updating data, and returning the static resource updating data to the client.
And the CDN caches the data which are not stored in the cache, returns the source public cloud flexible bandwidth IP to obtain the static resource updating data through a private network, and returns the static resource updating data to the user client side in the original path. As can be appreciated, the public cloud can determine the public cloud elastic bandwidth IP by deploying the elastic bandwidth layer.
On the basis of the foregoing technical solutions, optionally, after receiving a resource request of a client, the method further includes:
if the resource request target is a dynamic resource, determining a dynamic resource access domain name;
accessing the resource request to an application layer of the data center private cloud through a cloud private line between the public cloud and the data center private cloud through a reverse proxy layer deployed on the public cloud;
and the application layer of the data center private cloud interacts with the database layer of the data center private cloud to obtain dynamic resources, and the dynamic resources are returned to the client.
Dynamic resource access, namely migrating an entrance of an internet service from a traditional data center DMZ area to a public cloud, constructing a reverse proxy layer by utilizing the scalable mass bandwidth and elastic computing resources of the public cloud, communicating the private cloud from the public cloud to a data center through a high-bandwidth low-delay high-availability cloud special line, and reserving an application layer and a database layer related to sensitive data interaction in the data center to ensure the security of key data. Fig. 3 is a flow chart of dynamic resource access for hybrid cloud deployment according to an embodiment of the present invention, and as shown in fig. 3, a full path introduction of dynamic resource access traffic is described as follows:
when the dynamic domain name of the financial insurance industry hybrid cloud architecture application system which is separately deployed at the front end and the back end is accessed, the DNS server can analyze the public cloud elastic bandwidth IP to the user;
dynamic interaction is carried out to reduce the pressure of the private cloud application layer through reverse proxy long link optimization, and a resource request is proxied to the private cloud application layer;
for dynamic resources needing to be processed by an application layer and a database layer, the dynamic resources can reach a data center through a low-delay high-bandwidth high-availability cloud special line laid in advance;
the data center application layer can frequently interact with the local database layer, calculates the dynamic resource request and returns the final result to the user according to the original path.
According to the scheme, the feedback speed of the dynamic resources can be improved, and the safety of the dynamic resources can be ensured.
On the basis of the above technical solutions, optionally, the cloud private line between the public cloud and the data center private cloud includes at least two telecommunication lines and at least two communication lines;
the at least two telecommunication lines are respectively connected to at least two network service providing points; the at least two network service providing points are respectively connected to at least two machine rooms of the public cloud.
Fig. 4 is a schematic diagram of a hybrid cloud deployment cloud private line architecture provided in an embodiment of the present invention, and as shown in fig. 4, the present solution provides a high availability solution for the cloud private line, and the cloud private line is a bridge for getting through public cloud and private cloud, which is particularly important. Due to the fact that public cloud machine rooms are wide in deployment and distribution, multiple machine rooms are high in availability, and a cloud special line needs to be communicated with each machine room network, and high availability of the special line is guaranteed. The scheme designs a high-availability architecture which is communicated with a public cloud multi-machine room to deploy, one telecommunication and communication line is connected to one POP point, the other telecommunication and communication line is connected to the other POP point, and all the POP points are communicated with the public cloud multi-machine room. The so-called POP point is a network service providing point (or called local side), and generally, the closer the POP point is, the smaller the line signal loss is, and the higher the bandwidth guarantee can be provided for the connected user. The high network availability under the faults of operator lines, POP points or public cloud computer rooms is guaranteed.

According to the technical scheme, quick response of the user can be achieved, the elasticity, the flexibility and the economy of public cloud resources are fully utilized, and the aim of guaranteeing the safety and the continuity of the service is fulfilled.
On the basis of the above technical solutions, optionally, the method further includes:
if the preset period is reached, detecting the service state of the public cloud through global load balancing;
and if the service state meets the preset condition, switching the service access path from the access public cloud to the access data center private cloud.
Fig. 5 is a schematic diagram of a hybrid cloud deployment public cloud fault according to an embodiment of the present invention, as shown in fig. 5, where global load balancing may be a service or composed of one or more servers. Under the condition of public cloud maintenance or extreme faults, in order to guarantee service continuity, the service state of the public cloud is regularly detected through global load balancing, and the private cloud environment of the data center is automatically analyzed when the faults occur, so that the service continuity is guaranteed.
On the basis of the above technical solutions, optionally, the public cloud and the data center private cloud adopt security equivalent management.
In the scheme, the public cloud reverse proxy layer only provides static non-sensitive data storage, the reverse proxy dynamically interacts data, and the dynamic data is still stored in the data center private cloud. Meanwhile, the data center private cloud and the public cloud have the same safety requirements, so that safety integrated management is realized, and the safety of the whole service is ensured.
The invention provides a financial insurance industry mixed cloud architecture design based on front-end and back-end separation deployment by combining with a special business environment of an enterprise: the CDN edge node of the public cloud is used for quickly responding to the user, the reverse proxy layer is deployed on the public cloud, the advantages of public cloud computing resources, bandwidth scalability and economy are fully utilized, meanwhile, the application layer and the database layer related to sensitive data are deployed on the private cloud of the enterprise data center, and the risk of data leakage and loss is avoided. The hybrid cloud is connected through a low-delay high-bandwidth cloud special line with high availability, and the global load balance is automatically detected to ensure the service continuity. The service sensitive data does not fall to the ground at the public cloud end, and is managed in a safe and equivalent mode, so that the service safety is guaranteed.
