What is a gatewayThe term gateway is derived from the definition of the computer network, the gateway is also called the Inter-Network connector, protocol converter. The exact definition of a gateway is a connection between two computer programs or systems, and the gateway acts as a portal between two programs, allowin

Orange is a openresty-based API Gateway. In addition to the basic functions of nginx, it can also be used for API monitoring, access control (authentication, WAF), traffic screening, access speed limit, AB test, dynamic shunt and so on. It has the following characteristics:Provides a set of defau

Through the introduction of the previous articles, we can easily build up a few of the more important infrastructure services in the microservices system. So, in this blog post, we'll focus on how to design API Gateway concepts by agreeing to expose all microservices APIs.

An API gateway is a server that is the only portal to the system. From an object-oriented design perspective, it is similar to the appearance pattern. The API gateway encapsulates the system's internal architecture and provides a custom API for each client. It may also have
So far, we have introduced a lot of the content of Spring cloud, Ribbon, Hystrix, feign the knowledge that everyone is familiar with, we also mentioned in the previous micro-service is to split a large project into a number of small independent modules, And then through service management let these independent modules work together. So let's think about this. Two questions: 1. If there are many independent services in my micro-service that have to be serviced externally, how will the developer o
This essay goes on to learn a more important Component API Gateway service in MicroServices. When we finally have to provide external access to the micro-service architecture, we need a unified access portal, to hide our internal service URL details, which is a bit like the concept of the gateway in the LAN, this is the API

Through the previous sharing, we learned about several core facilities of the microservices architecture, through which we can build a simple microservices architecture system. For example, through spring Cloud Eureka to build a highly available service registry and realize the registration and discovery of services;Load balance through the Spring cloud ribbon or feign, and fault-tolerant protection with spring cloud Hystrix to avoid a failure spread. After the microservices are set up, we will
have much higher latencies. Of course, any WAN is much slower than a LAN. This means that the network used by the mobile local client differs greatly from the performance characteristics of the server-side Web application's LAN. A server-side web app can send a large number of requests to the back-end service without impacting the user experience, but the mobile client can only send a small number of requests.• The number of service instances and their location (host + port) are dynamically cha

As we all know, Docker has made a profound change in the IT world these years,From development to testing to operations, there is a shadow of it everywhere.It also facilitates the micro-service architecture and moves forward.
In the latest version of Docker (CE 17.03), with swarm mode the maturity,In a simpler scenario, you can no longer need a special 基础设施管理服务编排, 服务发现 , 健康检查 , and 负载均衡 so on.

rather than databases. But at first the idea was inspired by Shenli's article, "Micro-SOA: Principles of Service design and practices", which was thought of in conjunction with other ideas. The idea is only a utility model at present, the specific use of the effect also needs further verification, but only for the small and medium-sized development team, in the early implementation of the micro-service can completely replace the API
, there is an easy to ignore, but one of Netflix's most powerful basic services, it is Zuul Gateway services. The Zuul gateway is primarily used for intelligent routing, while also supporting authentication, zone and content-aware routing, aggregating multiple underlying services into a unified external API. One of the highlights of the Zuul
mainly done by pre-type filters, which match the request path with the configured routing rules to find the destination address to be forwarded, while the part of the request forwarding is done by the route type filter to forward the routing address obtained by the pre type filter.
Therefore, the filter can be said to be Zuul implementation of the API gateway function of the most core components, each inco

The API gateway Ocelot uses Polly to handle some failures.
In the process of implementing the API Gateway, another issue that needs to be considered is part of failure. This problem occurs in distributed systems when one service calls another service and times out or is unavailable.
What is Zuul?
Front door. API Gateway.zuul is a JVM based router and server side load balancer by Netflix.
Entrance to all requests.
As an edge service application, Zuul are built to enable dynamic routing, monitoring, resiliency and security. As a boundary application service, Zuul can realize dynamic routing , monitoring, elasticity and security.
