Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
First, several terms related to the present invention are analyzed:
SaaS system (Software-as-a-Service): meaning software as a service, i.e. providing a software service over a network. The SaaS platform supplier uniformly deploys the application software on the server of the SaaS platform supplier, a user can order the required application software service from a manufacturer through the Internet according to the actual working requirement, the cost is paid to the manufacturer according to the amount and time of the ordered service, and the service provided by the SaaS platform supplier is obtained through the Internet.
Nginx: a high-performance reverse proxy server is installed at a destination host and is mainly used for forwarding client requests, a plurality of http servers are arranged in a background to provide services, and Nginx has the function of forwarding the requests to subsequent servers and deciding which target host to process the current requests.
Lua: the script language is a compact, light-weight and extensible script language and is also the script language with the highest number performance.
Currently, server information needs to be set in a Nginx configuration file in a Nginx general load balancing manner, a polling server list is written in an upstream object in http, and the increase and decrease of cluster servers need to manually update the configuration file of the Nginx, which is troublesome and easy to make mistakes. While there is no solution for scheduling a set of traffic requests of the same characteristics to a given server. And isolation is not performed between users, so that user data is acquired and tampered inadvertently or maliciously by others.
Based on this, embodiments of the present invention provide a traffic distribution method, a system, a computer device, and a storage medium, where traffic is distributed to different servers according to request characteristics, so as to implement application logic isolation for different users, and improve data security of the users.
The technical scheme provided by the embodiment of the invention is different from the existing most of flow scheduling systems, and most of the systems are scheduled based on load balancing strategies such as flow black and white lists, percentages and the like. According to the scheme, the flow of the same organization is dispatched to the same group of servers through partition strategy load balancing, so that application logic isolation of different organizations is realized, and the technical problem that a flow load balancing method in the prior art is single in balancing strategy is solved. The scheme is realized based on Nginx and lua scripts, the principle is simple, no business code is invaded, the scheme is irrelevant to business developers, and users do not feel. The load balancing scheduling strategy is processed by the lua, the online and offline processes of the cluster server are fully automated, Nginx configuration is not required to be modified, and manual operation error accidents are reduced.
The embodiments of the present invention will be further explained with reference to the drawings.
As shown in fig. 1, fig. 1 is a schematic diagram of a system architecture for performing a traffic distribution method according to an embodiment of the present invention. In the example of fig. 1, the system architecture includes at least one organization 110, a nginnx gateway 120, and at least one designated partition 130. It should be noted that at least one organization is assigned under each designated partition, and the organization includes at least one user.
Those skilled in the art will appreciate that the architecture of the apparatus shown in fig. 1 is not intended to be limiting of the system architecture, and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
Various embodiments of the present invention are proposed based on the hardware structure of the above system architecture.
As shown in fig. 2, fig. 2 is a flowchart of a traffic distribution method according to an embodiment of the present invention. The traffic distribution method of the embodiment of the present invention includes, but is not limited to, step S110 and step S120.
Step S110, receiving a request sent by a user, and determining an organization to which the user corresponding to the user request belongs;
step S120, the user request is sent to the designated partition of the organization.
Specifically, users are mapped to an organization, data and resources of the same user belong to the organization, and the Nginx gateway sends a user request to a designated partition to which the organization belongs for processing. By forwarding the requests of the same organization in all accesses to the exclusive partition system, the data and resources among different organizations are completely isolated and do not influence each other, and the safety of user data is effectively improved.
Referring to fig. 3, step S120 may be specifically implemented by the following steps:
step S210, determining a user organization code according to the organization;
step S220, determining a designated partition address corresponding to the user organization code according to the user organization code;
step S230, the user request is sent to the designated partition for processing based on the designated partition address.
Specifically, each organization generates a designated organization code for it at the beginning of registration and assigns a designated partition. The Nginx gateway can determine a corresponding designated partition address according to the user organization code, and send a user request to the designated partition for processing based on the designated partition address.
The organization means an enterprise, a group, or the like.
It will be appreciated that after a user is registered, the user organization code may be determined from the user registration name. The user organization code may also be determined based on the user network address.
Referring to fig. 4, step S220 may be specifically implemented by the following steps:
step S310, determining a partition code corresponding to the user organization code according to the user organization code;
step S320, determining a designated partition address corresponding to the partition code according to the partition code.
Specifically, the nginnx gateway accesses the corresponding relationship between the user organization code and the partition code, can find the partition code through the user organization code, and further finds the designated partition according to the partition code.
It should be noted that the correspondence may be stored locally in the Nginx, or may be stored in any accessible place, such as a database.
Specifically, the nginnx gateway obtains a corresponding designated partition address from the second preset address mapping table according to the partition code.
It can be understood that the nginnx gateway obtains the corresponding designated partition address from the first preset address mapping table according to the user organization code.
The first preset address mapping table and the second preset address mapping table may be stored in any accessible place, such as a database.
The traffic distribution method of the present invention is illustrated below by two practical examples.
Example one, referring to fig. 5, the method includes:
nginx receives all user requests:
(1) monitoring a domain name:
server_name h3yun.com；
(2) associating the backend application:
set$backend www.h3yun.com；
rewrite_by_lua_file loadbalance.lua；
proxy_pass http://$backend；
2. request identification:
analyzing the organization code of the current requesting user from the user request by the lua script;
3. searching for the IP of the specified partition:
and searching the IP of the designated partition of the organization according to the organization code EngineCode.
4. Request forwarding:
nginx forwards the request to the designated partition to which the user organization belongs.
Example two, referring to fig. 6, the method includes:
nginx receives a user request;
analyzing the user request by the lua script to obtain the current user organization code:
engineCode＝ngx.var.cookie_EngineCode or ngx.var.get_uri_args()[“EngineCode”]；
obtaining partition codes of organizations according to egineCodes:
shardKey＝ngx.shared._ups_zone:get(engineCode)；
finally, the lua script accesses the address mapping table to obtain the IP of the designated partition through http request:
webip＝http:request_uri(“/GetWebIpByShardKey”,{method＝“GET”})；
then lua sets Nginx variable ngx.var.back ═ webip;
nginx forwards the user request to the designated partition to which the organization belongs.
