In practical operation, the units, modules and sub-modules may be combined or may be arranged singly, and the invention is not limited thereto.
For a better understanding of the present invention, embodiments of the present invention are described in detail below in connection with the exemplary system illustrated in FIG. 3.
As shown in fig. 3, the example system includes: the system comprises a client and a server cluster, wherein the client obtains a service from an access point which initiates a service request to the service, and the access point (namely, one server or one of a group of servers) finds a specific service on the server cluster through a service addressing mechanism and returns the specific service to the client. The service deployment also meets the conditions of service combination, service nesting and the like under the architecture layering concept and the micro-service concept.
The example system realizes the functions of cloud environment service deployment and service addressing based on the directed circular ring model, and the specific realization process comprises the following steps: (1) there is a division principle of address space on the directed torus; (2) Deploying servers of the server cluster on the directed circular ring and determining rules of the jurisdiction range; (3) Establishing a comparison routing table relation between the static server identification and the directed circular ring address space; (4) service deployment and service addressing rules; and (5) a deployment mode of the server cluster network. These five processes are described separately below.
(1) Division principle of address space on directed torus
First, a directed torus model as shown in fig. 4 is built, and the address space is equally divided on the directed torus. The size of the directed torus address space is initially defined as 2 to a certain power of 2 c (e.g. 2) 8 = 64). The default convention ring positive direction is clockwise (clock direction), i.e., 0,1,2, 3. The positioning formula of the key value in the directed circular ring is as follows:
address＝hash(key)％2 c (1)
wherein,% represents a remainder operator;
(2) Rules for server deployment of server cluster on directed torus and determining jurisdiction
Assuming there are k servers in the server cluster, each server has a unique static identification (e.g., server IP address) that can be used to provide services. Taking a docker container as an example, as a server, the static IP address of the container may be set as its unique identity. And (3) taking the static IP identification of the server as a key value in the directed ring, and calculating to obtain the position of the server in the address space by using the formula (1).
Assuming that the address value corresponding to each server in the server cluster is calculated by using the static IP of the server as the key value, the results are sequentially arranged from small to large: a. The 1 ,A 2 ,A 3 ,...,A k . The correspondence falls on the directed circle model as shown in fig. 5. Hereinafter, the following will be: a. The 1 ,A 2 ,A 3 ,...,A k Refers to the servers in the cluster and their order.
As shown in FIG. 5, there are k servers A in the directed circle i (i =1,2, 3.., k.) cut into k directed arcs, contract Server A i The administered address range is [ A ] i ,A i+1 ) (left-closed and right-open interval), i.e. directed arcs as shown in FIG. 6
(Note that the direction of the directed arc is irreversible, and the reversal is expressed by negative values, i.e. on a circle
). Thus, can obtain A i The arc range of jurisdiction of (c) is written as follows:
A i ≤address＜A i+1 (2)
(3) Establishment of contrast routing table relation between server static identification and directed ring address space
The static identifier of the server is used as a key value, and the address space position of the server corresponding to the directed circular ring is calculated by using a formula (1). And meanwhile, a cutting principle of the directed circular ring address space is provided, and in order to quickly locate the address position of the server on the directed circular ring, a comparison relation between the static identifier and the address of the server can be established as a routing table in the service deployment stage.
For example, assume that there are 16 servers in the server cluster, and the static IP of the server is selected as the static identifier, and the address space is set to 2 4 The power directed circular model substitutes the IP of each server as a key value into formula (1), and the calculated data is correspondingly filled into a routing information table, as shown in table 1 below:
TABLE 1
Based on table 1 above, fig. 7 shows a directed circle link point and server static identification routing relationship diagram.
(4) Service deployment and service addressing rules
Before deploying the service to the server, that is, setting the naming rule of the service in advance, for example:
GroupName
_ServiceName
the service name may be included in the service request, and the GroupName is a group name prefix, and may be set by a service deployed on one (or one group of) servers as needed. For example, services that use a common database data are ascribed to the same packet name. When the calculation service corresponds to the address space position in the directed torus, the GroupName may be substituted into formula (1) as a key value to calculate the address value of the position of the service in the address space. Then, the position of the directed arc in the directed circular ring where the service is located is found according to the formula (2). And finally, determining the address information of the server deployed by the service according to the static server identifier and the routing relation table of the directed ring.
Therefore, a simple service deployment and service addressing ring model on the intranet can be established: the servers on the server cluster are correspondingly deployed on the directed ring according to the steps, the client initiates a service calling request, the access point server on the server cluster acquires the group name GroupName in the service request and calculates to obtain the server address information corresponding to the service, the server on the corresponding server is called to perform request processing, and then the processing result is returned to the client.
In actual operation, if the service includes a self-service or a micro-service, the service addressing can be realized as long as the naming rule and the deployment rule of the service are guaranteed to comply with the above requirements. In addition, each server on the directed ring can be a group of servers, so that high reliability and high availability of multi-activity, load balancing and the like are realized.
(5) Deployment mode of server cluster network
When the client sends a request to a simpler intranet cloud environment service cluster for service calling, deployment can be performed according to the above manner. However, when considering that the client sends the request through a domain name system, an IP, and the like on the public network, the following two-point adaptability adjustment needs to be performed on the deployment of the server cluster on the directed torus.
1. Configuring DNS Domain name Server
The mapping relation between the external domain name and the access point address of the internal actual server is configured on the DNS server, so that the aim that the client on the public network can be communicated with the actual target server through the domain name is fulfilled.
2. Deploying special servers with distribution function
And selecting a plurality of servers on the directed ring with the server cluster as DNS domain name mapping access points. The access point server needs to have two parts of capability: the first one is that the capability of receiving external requests and distributing the requests to the servers belonging to the corresponding services on the ring according to the routing relation table for request processing is required to be provided; and the second is that the system has conventional deployment service and provides the capability of processing service requests.
For example, fig. 8 shows another example system, as shown in fig. 8, it is assumed that K servers in a server cluster form a directed torus according to the above deployment manner to form a server cluster network, and a correspondence between a server IP and a space address on the torus is represented by a routing table (it should be noted that addresses in the routing table are from small to large, which does not mean that the IP is from small to large). One or more servers on the directional ring are selected as access points (the access point itself is also one server on the ring, and multiple servers can be set as access points to realize multi-point access).
The request processing flow based on the example system of fig. 8 includes: the client sends a service request by calling a domain name, and the DNS server processes domain name mapping to send the request to an access point server A on the ring j Access point server A j For group Name _ ServiceNa in service requestme finds the address value in the address space according to the formula (1), and then finds the server A deployed by the service according to the formula (2) and the routing relation table e Access point server A j Call Server A by RPC e And finally returning the processing result to the client side in the original way.
As can be seen from the above description, the embodiment of the present invention constructs a service deployment and service addressing model in a cloud environment based on a directed torus, and provides a novel service deployment manner with high extensibility, a simple and efficient service addressing manner. The embodiment of the invention can be implemented in the Internet industry which assists the concept of 'micro-service' in the future, can ensure that the service can be deployed on a huge server cluster under the condition of rapid increase of the service quantity, can also ensure that the service addressing time is not prolonged along with rapid increase of the service quantity, and can ensure the high-efficiency response capability of an application system.
Based on similar inventive concepts, the embodiment of the present invention further provides a service processing method based on a cloud environment, and the method is preferably applicable to the service processing apparatus described above.

And 904, executing the service corresponding to the service request based on the determined server to which the service belongs, and returning a service processing result to the client.
In actual operation, the server may be a group of servers.
Preferably, one server from the group of servers may be selected to execute a service corresponding to the service request according to a load balancing policy.
The method comprises the steps of determining the position information of a server in a server cluster according to a request name in a received service request, then determining the server based on preset routing information and the position information, then executing the service corresponding to the service request based on the determined server, and returning a service processing result to a client.
In actual operation, the routing information may be set as follows: firstly, establishing a corresponding relation between position information of each server in a server cluster and a static identifier of each server based on a directed circular model; and then generating routing information according to the corresponding relation.
Specifically, a plurality of positions may be set on the directed torus model according to the number of servers in the server cluster; and then determining the corresponding relation between the position information of each server and the static identifier of each server according to the position number and the static identifier of each server.
