Spring Boot + spring Cloud microservice implementation tutorial 2, springcloud The previous article has explained the simple steps for creating a maven project in spring boot. I believe that many people familiar with Maven + Eclipse are familiar with the development of common tools. This article mainly explains how to create a maven project, build the framework of spring boot + spring cloud to implement microservices, but before that, we need to first

Microservice monitoring based on five principlesGuideOur requirements for microservices can be summarized into one word: speed. This demand for faster provision of fully functional and reliable software completely changes the software development model. There is no doubt that this change has an impact on software management, including the way systems are monitored. In this article, we will focus on the major changes that need to be made to effectively

Based on the. net core microservice framework and the. netcore framework1Preface Surging uses high-performance RPC remote service calling. If json.net is used for serialization, the performance will not reach the optimal level. Therefore, protobuf and messagepack serialization components are extended to support RPC binary transmission. Thanks to the White Paper and wordless Zonciu, messagepack serialization is added, which makes the surging performanc

First, let's figure out a few things:1. What is the Monitored object?2. What are the monitoring metrics?3. What are the dimensions for monitoring?Monitored object1. User-side monitoring: monitoring of service functions provided to users2. interface monitoring: RPC interface monitoring on which business functions depend3. Resource Monitoring: monitoring of resources on which interfaces depend4. Basic monitoring: monitoring of the health status of the server itselfMonitoring metrics:1. Request vol

In the Nginx reverse proxy mode, the page loading is incomplete or the 502 bad gateway appears directly. There are many cases of 502 bad Gateway, most of which are related to the setting of the Nginx timeout problem. The following is a discussion of a situation that is relatively rare but has to be noted. Presence Environment Nginx work in reverse proxy mode, listening to non-80 ports (this is important

Run the MongoDB microservice on Docker and KubernetesGuideDocker is an open-source application container engine that allows developers to package their applications and dependencies to a portable container and then publish them to any popular Linux machine, you can also achieve virtualization. Containers fully use the sandbox mechanism and do not have any interfaces between them. This article describes how to use Docker and Kubernetes to build a set

The gateway is used to control the flow of the process. The Gateway can consume or generate a token. The gateway is displayed as a diamond graph with a small internal icon. The icon indicates the type of the gateway. Basic Branch First, use process variables to write a basic process with branches Flowchart: Deploym

SpringCloud microservice architecture-based Hystrix circuit breaker, springcloudhystrix I. What is Hystrix? In a distributed environment, some of the Service dependencies inevitably fail. Hystrix is a database that helps you control the interaction between distributed services by adding latency tolerance and fault tolerance logic. Hystrix isolates access points between services, stops cascade failures, and provides rollback options to improve the over

And even with Razor to write a View, it's not difficult to make a Web site that does not iis+asp.net MVC. But according to my strategy, the complex web site will still choose to use ASP. NET MVC,

Dora-RPC-Dragon Boat Festival upgrade PHP microservice development kit Dora-RPC-Dragon Boat Festival upgrade. Currently, the master has added a large number of features in beta. Several companies have been using the project online for more than a year. of course, they have made some changes based on this prototype. Recently, the upgrade has improved a lot. for example, if unique function is removed, the performance will double. it is found that some

1. Timeout: for example, the order service calls the product-service interface of the commodity service for order-service: This interface requires a certain amount of response time. This exception occurs when you call it. Solution: In the order-service configuration file application. yml, set the timeout time: Timeout Configuration:The default optons readtimeout value is 60, but because hystrix times out in 1 second by default, response timeout in 1 second is Server: Port: 8781 # specify the Re

First, IntroBefore the gateway, many netizens concerned about how to implement the interface. To understand the change of the next machine variable, it is how to trigger the human-machine interface animation in one step.This step-by-step trigger is essentially a bulk data change (DataChange) event for the variable group (s), which raises the variable (TAG) value Update (ValueChange) event, which eventually triggers an animated script (Action) of the e

You can try to clear the browser cache and access your FTP to see if you can log on Cause A server (not necessarily a Web server) serves as a gateway or proxy to meet customer requirements (such as a Web browser or our CheckUpDown robot) to access the requested URL. This server receives an invalid response from the upstream server to fulfill its requirements.Fixed 502 errorsGenerally, this problem is caused by poor communication between IP addresses o
