Referring to fig. 1, fig. 1 is a decentralized cloud computing platform disclosed herein. In this embodiment, the decentralized cloud computing platform is implemented based on DHT (Distributed Hash Table ), and includes: a plurality of decentralised nodes, each decentralised node comprising: DHT instance and POD instance.
In this embodiment, the process of implementing the decentralized cloud computing platform based on the DHT includes: collecting a plurality of nodes; deploying a proxy process in each node; the DHT instance and POD instance are deployed in the respective nodes using proxy processes to translate each node into an decentralized node. The proxy process may also be set in a proxy server, where each node corresponds to one proxy server.
Based on the platform provided in this embodiment, a user may develop a client program and a server program, deploy the server program on some of the decentralized nodes of the platform (i.e., deploy a service), and then access the server program on the node with the client (i.e., access the service). That is, after the user deploys the service on the platform, DHT instances on the nodes of the platform are updated accordingly, and POD instances corresponding to the service are generated.
Specifically, each decentralizing node comprises a proxy process which is used for managing and deploying platform tasks. Meanwhile, the proxy process deploys DHT instances in the decentralized node such that all DHT instances form a DHT network.
If a service is deployed on the platform, a service information list is provided in the DHT instance on each node, where the service information list includes a plurality of service information, and each service information includes: DHT communication information and/or extranet communication information, service ports and extension information, etc. Since there is one service information list in each decentralised node, information sharing can be achieved. Storing service names and service information in a service information list according to a Key-Value Key Value pair mode; key is service name, value is service information; wherein, the service information corresponding to different decentralizing nodes is different. One service corresponds to one POD instance, and the POD instance is used for responding to an access request initiated by the corresponding service. Multiple POD instances may be included in one de-centralized node.
It should be noted that, one service is deployed on a plurality of decentralizing nodes, and after the service is deployed on a certain decentralizing node, service information corresponding to the current decentralizing node can be obtained; one de-centralized node can therefore be considered to correspond to one service message. All the service information is arranged into a list, and a service information list can be obtained. Because each decentralizing node has one DHT instance, each decentralizing node can complete broadcasting of service information based on a DHT network protocol, so that each decentralizing node has one service information list in the DHT instance, and information sharing can be realized.
It can be seen that the present embodiment implements a decentralized cloud computing platform using DHT, where each node in the platform includes a DHT instance and a POD instance, so each node becomes a decentralized node. The decentralized nodes can realize information sharing and exchange by utilizing the DHT instance and the POD instance, so that the platform has P2P network capability and the service performance of the platform is improved.
Referring to fig. 2, fig. 2 is a service deployment method disclosed in the present application. In this embodiment, the method is applied to the decentralized cloud computing platform provided in the foregoing embodiment, and includes:
s201, receiving a deployment request of the service.
It should be noted that, the service is a server program obtained by SDK development of the decentralized cloud computing platform.
S202, determining a plurality of target decentralizing nodes for deploying the service.
Specifically, a plurality of target decentralised nodes deploying the service may be determined using a service orchestration policy preset in the platform. Service orchestration policies such as: a random selection policy, a load balancing policy, etc. Deployment services may be implemented by invoking the Put interface of the DHT.
S203, storing service names and service information of services in DHT instances of the target decentralizing nodes, so that the target decentralizing nodes can complete broadcasting of the service information based on a DHT network protocol, and a service information list is obtained.
In one embodiment, the service information list includes a plurality of service information, where the service information includes: DHT communication information and/or extranet communication information, service ports, and extension information.
S204, storing the service information list into DHT examples of the target decentralizing nodes.
In one embodiment, storing service names and service information for services in DHT instances of respective target decentralized nodes includes: storing service names and service information of the services in the DHT examples of the target decentralizing nodes in a Key-Value Key Value mode; key is service name, value is service information; wherein, the service information corresponding to different target decentralization nodes is different.
It should be noted that, deployed on the decentralized cloud computing platform is a server program, where when the server program is deployed on the decentralized cloud computing platform, a TCP port or a UDP port is configured to provide a service. The user may develop a client program based on the SDK (Software Development Kit ) on the decentralized cloud computing platform. The client program is used for accessing the server program deployed on the platform.
From the above, the embodiment realizes the decentralised cloud computing platform based on the DHT. In the service deployment process, the platform can realize information sharing and exchange by utilizing the DHT, so that the platform has P2P network capability and improves the service performance of the platform.
Referring to fig. 3, fig. 3 is a service access method disclosed in the present application. In this embodiment, the method is applied to the decentralized cloud computing platform provided in the foregoing embodiment, and includes:
s301, receiving a service access request.
In one embodiment, the access request is initiated by a client of the service, the client being obtained using SDK development of the decentralized cloud computing platform.
S302, inquiring a service information list of the service according to the access request.
The service information list is stored in a DHT instance of a decentralizing node, wherein the decentralizing node is a node with services deployed in the decentralizing cloud computing platform.
In one embodiment, querying a service information list of a service according to an access request includes: extracting a service name of a service from the access request; querying a service information list by using a service name, wherein the service information list comprises a plurality of service information, and each service information comprises: DHT communication information and/or extranet communication information, service ports, and extension information. The query service is implemented by invoking the Get interface of the DHT.
S303, selecting target service information in the service information list, and responding to the access request by utilizing the target service information.
When selecting target service information in the service information list, the node with a short network distance and good network quality is used as the optimal selection target. Of course, the selection may also be made according to other strategies, such as random selection. Because one decentralizing node corresponds to one service information, one service information is selected, namely the node where the service information is located is selected to respond to the request.
In one embodiment, responding to an access request with targeted service information includes: and if the target service information comprises the external network communication information, responding to the access request by using the external network communication information.
In one embodiment, responding to an access request with targeted service information includes: if the target service information only includes DHT communication information, the access request is responded by using the DHT communication information. Wherein responding to the access request with the DHT communication comprises: and forwarding the access request to the POD instance in the decentralized node corresponding to the target service information by using the DHT communication information, and responding to the access request by using the POD instance.
From the above, in this embodiment, service access is performed on the decentralized cloud computing platform implemented based on DHT, and in this process, the platform may utilize DHT to implement information sharing and exchange, so that the platform has P2P network capability, and platform service performance is improved.
The following describes a decentralized cloud computing platform, and the decentralized cloud computing platform and the service access method described above may be referred to each other.
The embodiment provides a cloud computing platform based on decentralization, which comprises: platform construction, service deployment, service access and the like.
And (3) building a platform: the platform collects and manages the decentralised nodes. A proxy server (in which a proxy process is provided) for managing and deploying platform tasks is provided in each of the decentralized nodes, and a DHT instance (i.e., the DHT in fig. 4) is deployed in each of the decentralized nodes by using the proxy server, where all DHT instances form a DHT network.
Service deployment: the user develops a server program and deploys the server program on the decentralized cloud computing platform, and simultaneously configures a TCP (Transmission Control Protoco, transmission control protocol) port or a UDP (User Datagram Protocol ) port to provide a service. Specifically, when a server-side program is deployed on the decentralized cloud computing platform, an appropriate decentralized node may be selected on the current platform. If the proxy server in the selected decentralized node receives the deployment message, the image is downloaded and the service is started. Referring specifically to fig. 4, in fig. 4, deployed services run in POD (container) instances (i.e., PODs in fig. 4), one service corresponding to each POD instance.
After the service is started, the proxy server performs service registration (i.e. service deployment), and the specific operations are as follows: the Put interface that invokes the DHT instance receives and stores the < Key-Value > Key Value pair. Wherein, the key is a character string of the service name, such as a format of the domain name: com. Value is service information of the current service in the current decentralization node, and includes: DHT communication information (communication IP/Port of DHT, etc.) and/or external network communication information (external network IP, etc.), service ports (POD ports, etc.), and extension information. And, the DHT instance in each of the decentralised nodes can broadcast key-Value pairs to other decentralised nodes based on DHT network protocols, such that there is a list of values on each decentralised node. Value can be queried later through the Get interface. When inquiring, the input parameter is Key (service name), and the input parameter is a list of Value. For the same service, in DHT instances of different decentralised nodes, the keys are the same and the values are different.
Service access: before service access, call Get interface to query the list of values, then select one Value from the list as the target Value, and schematic diagram of selecting the target Value can be seen in fig. 5. Since one Value corresponds to one decentralizing node, selecting the target Value means selecting the decentralizing node corresponding to the target Value to provide the service. At this time, a communication channel is established with the de-centralized node corresponding to the target Value, and the communication capability of a transmission layer (TCP or UDP) is provided for an upper layer. Of course, TCP may be further encapsulated to provide the communication capabilities of HTTP (Hyper Text Transport Protocol, hypertext transfer protocol).
Specifically, a client program developed by a client and a server program communicate at an application layer. In the decentralized cloud computing platform, the external network communication information is not necessarily stored in each decentralized node, so that the data transmission of the client and the server needs to be ensured by using a DHT communication protocol. That is, the DHT communication information is used to forward the access request to the POD instance in the decentralized node corresponding to the target Value, and the POD instance is used to respond to the access request.
The underlying protocol stack is shown in fig. 6. Specifically, a layer of proxy protocol for TCP or UDP is encapsulated on the basis that the DHT can communicate, and the original TCP or UDP data packet is sent to the TCP or UDP port of the service.
For example: the server program monitors the UDP port of the local 8080 to provide service to the outside, and the service name is www.abc.com; the client wants to send a UDP signaling (called traffic signaling) to the 8080 service of the service www.abc.com. Based on the service name www.abc.com, a POD instance is located first, and communication information included in the service information is acquired. If only DHT communication information exists in the communication information, the client sends a proxy signaling (comprising a service name, a port type and an original signaling), and after receiving the proxy signaling, the server sends the original signaling to a monitoring port (8080) of a local server program according to the service name, the port and the port type; the server program then receives a signaling from the client from the 8080 port, enabling end-to-end communication. If the communication information has the external network address, the part of the DHT transmission protocol can be omitted, the external network address is directly acquired (acquired by Get interface query interface), and the end-to-end communication is completed by using TCP/IP.
Therefore, the decentralised cloud computing platform provided by the embodiment solves the problems of stable supply and difficult operation and maintenance of the decentralised service nodes. Based on the high-quality DHT network, the development threshold of service discovery and network communication is reduced, meanwhile, the development efficiency is greatly improved, and information sharing and exchange are realized.
