Churyang Summary Micro-service is not a stone crack inside, is based on similar SOA, Blackboard, C/S and other application architectures based on the integration of Agile development, devops and other concepts based on the development of The advantages of microservices compared to traditional applications (rapid deployment, de-center, good isolation, etc.), and many disadvantages (more complex, communication

Many people talk about " microservices " and are grappling with an old problem more than 20 years ago ; Particle size "; What is the " granularity" of microservices partitioning ? More than 20 years , many people are taking a " Standard answer " ; particle size Span style= "font-family: ' Helvetica Neue '"; In doing software development. Unfortunately, when you have been using the so-called " Standard a

The series of articles on microservices architecture will describe the definition, characteristics, application scenarios, evolution of enterprise integration architecture, microservices transformation ideas and technical decision-making considerations in several articles, the following uses IBM technology as an example to describe how to transform the microservice architecture. Why microservice Architect

Building Microservices-PDF documentation, microservices-pdf I translated several articles in English that are based on Spring Cloud and Netflix OSS to facilitate sharing and exchange, and sorted them into PDF documents.

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.

Attention:If you are working on microservices, there is a need for mutual invocation between services, and the interfaces between services and APIs must generate the management documentation of the system. If you want to better manage your API, you want to have a tool to solve all the API-related things one-stop, then, swagger will be a good choice, the following for you to introduce swagger is the use of methods, if there is wrong, but also to correc

balancing over a WAN. Support Dual standby hot (keepalived or Heartbeat). The dependence on the network environment is relatively high.Nginx: 7-tier, event-driven, asynchronous, non-blocking architecture, high concurrency support for multi-process load balancer/reverse proxy software. You can do some diversion for HTTP for domain names, directory structures, and regular rules. The failure of the server is detected through the port, such as the status code returned by the server processing the p

information about each product. Another interesting example of the API mix is the Netflix Video Grid.Writing API mix code with a traditional asynchronous callback method will let you quickly fall into a callback hell. Code can become confusing, incomprehensible, and error-prone. A better approach is to use a responsive approach to write API gateway code in a declarative style. Examples of responsive abstractions are the future in Scala, the completablefuture in Java 8, and promise in JavaScript

by function and business, freeing the parts from each other. A typical simple microservices architecture has at least the following parts:1. UI layer: The front-end visual layer, including web-side web pages, mobile apps, and PC clients.2. Gateway Layer: Gateway layer similar to our home use of routers, can redirect inbound requests to the target service, and the site of the micro-services to consolidate packaging output out of the station. The UI la

Load balancing is an essential name for any high-availability, high-load system. In a large-scale distributed computing system, a service in a single case, it is difficult to deal with a variety of unexpected situations. Therefore, load balancing is a solution that allows the system to distribute traffic in the event of a performance bottleneck or in some of these states. In the Springcloud system, many of Netflix's best products have been added, one of which is the Ribbon for server-side load b

Quickly set up Feign in microservices and set up Feign in microservices Build a declarative REST client feign in the microservice architecture ].Feign is a declarative Web service client. This makes writing to the Web service client more convenient. Use Feign to create an interface and annotate it. It has support for pluggable comments, including Feign comments and JAX-RS comments.
