Embodiment Construction

[0023] The following describes the detailed technical solutions, features and advantages of the present invention by taking a mainstream Nginx reverse proxy server as an application example of an API gateway.

[0024] 1. Configure static routing table information on Nginx or deploy a management service module that supports dynamic routing table updates;

[0025] 2. Deploy the routing service module including the implementation process of the load balancing method of the present invention on Nginx;

[0026] 3. The client initiates a microservice request to the API gateway, which contains the microservice identification information as GetOrders;

[0027] 4. The API gateway checks the existence of the microservice identifier GetOrder from the microservice routing table, and retrieves the business cluster type it belongs to as Order;

[0028] 5. The API gateway retrieves the list of eligible back-end microservice containers from the container routing table according to the busine...

Abstract

The invention belongs to the technical field of cloud computing, and relates to a load balancing algorithm. An API gateway load balancing algorithm oriented to a small-scale microservice architecture, comprising the following steps: (1) judging whether the microservice identifier in the request source is included in the API gateway routing table; (2) determining the business cluster to which it belongs according to the microservice identifier ; (3) Retrieve the list of eligible back-end microservice containers according to the business cluster information; (4) Obtain the last digit of the millisecond level of the API gateway instant time, take the remainder of the number of back-end microservice containers, and use the remainder as the backend The index of the list of end-side microservice containers is selected as the eligible back-end micro-service containers; (5) The API gateway carries the micro-service request parameters to initiate a service call to a specific back-end micro-service container. The API gateway load balancing algorithm oriented to the small-scale micro-service architecture of the present invention greatly improves the high availability of the API gateway system, and at the same time, the simple load balancing algorithm is easy to implement and has strong balance.

Description

technical field [0001] The invention belongs to the technical field of cloud computing, and relates to a load balancing method. Background technique [0002] As a lightweight cloud computing solution, the microservice architecture splits large and complex software applications into multiple microservices based on business dimensions. It has the characteristics of decentralization and realizes agile development and rapid deployment. Microservice architecture has been more and more widely used in the field of computer cloud computing. In the microservice architecture, an API service gateway is usually built to uniformly process requests from various clients. This architecture hides various services that actually provide business operations in the backend, which can not only protect the business operation module, but also facilitate the Flexible configuration and expansion. Due to the large number of back-end microservice containers, the solution will involve how to choose a ...
