Chris Richardson microservices Translation: Building process communication for microservices architecture

with interprocess messaging mechanisms, and when designing a service's communication pattern, there are several issues to consider: how the service interacts, how to define the API, how to upgrade the API, and how to handle local failures. The microservices architecture has two IPC mechanisms available: The asynchronous message mechanism and the synchronous request/response mechanism. In the next article,

Deploy Postfix messaging System (i) protocols for messaging system roles and messaging systems

The mail system is not a single system, but consists of different components and functions, and in order to realize the communication of mail, it requires some protocol support (i.e. mail protocol). The following is a brief description of the messaging system role and mail system protocols. Role of the messaging system MTA (Message transfer agent): Commonly referred to as mail Server Software, responsibl

Micro Service guide North (i): what is microservices

effectively split applications for agile development and deployment. Micro-Service application is a distributed system, which inevitably brings inherent complexity, and the developer needs to choose the protocol message passing rule and complete interprocess communication. This technology is more complex than the single-use, micro-service. With regard to the database schema of microservices, this transactional operation is easy to solve for m

Microservice architecture (I): What is microservices?

integration points, the microservice architecture has a higher risk of publishing. Code duplication: some underlying functions need to be used by multiple services. To avoid "synchronous coupling into the system", you sometimes need to add some code to different services, this will lead to code duplication. Complexity of Distributed Systems: as a distributed system, microservices introduce complexity and other issues, for example, network latency,

The first step in building microservices: Where does microservices come from?

How to build MicroServices with API gateways

applications, you may want to send more requests. For example, as Amazon says, they call hundreds of services when they display their product pages. However, the client sends many requests over the LAN, which can be inefficient on the public web and not feasible on the mobile network at all. This approach also makes client-side code very complex.Another problem with clients calling MicroServices directly is that the protocol used by some services is

Using spring Cloud Zuul as a gateway to integrate multiple microservices into one swagger service under the MicroServices architecture

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

"MicroServices" four: Easy fix springcloud microservices-load Balancing Ribbon

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
