submit a code, found and others submitted conflict, so because you are submitted after the person, you have the responsibility to merge code, finally merge successful, and so on again, when the discovery conflict, you are not very annoyed. The greater the team size, the greater the probability of conflict. So should be split into different modules, every 10 people around the maintenance of a module, that is, a project, the first code conflict probability is much smaller, and there is a conflict

difficult to perform such refactoring.Because of these problems, it is seldom reasonable for clients to communicate directly with MicroServices.Using the API GatewayIn general, a better approach is to use the so-called API gateways. 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 a

process is fully automated process, the developer submits code to the code server, the code server triggers the continuous integration build, test, if the test pass will be automatically pushed through the Ansible script to the simulation environment, in practice for the online environment is the first to go through the audit process, through before it can be pushed to the production environment. Improves productivity and controls some of the online

microservices architectures, and the spring BOOT+MONGODB solution is one of the most optimal solutions for data governance under the MicroServices architecture.Of course, if we are unfamiliar with the microservices architecture, Spring Boot, and MongoDB, we may need to go a lot of detours. The wrong technical solution

ago will not be released to the order module in a timely manner. If all two modules use a single program architecture, it is likely that the snapping up of the business will fill up all the resources, and even other normal access to the system's user resources are occupied, causing the system to crash. In Dev/ops today, developers and architects need to think more about the impact of the hardware architecture level on program applications.Method of hosting eshop on container

Over the past two years, the authors have been involved in the MicroServices team in overseas deliveries to enhance the scalability of the Finance system for customers. The author's team, 3 pairs of development (pair programming, 2 dev for pair) Support 11 services for customers, and the continuous deployment pipeline (CD pipeline) is an essential technical practice. This sharing author will share the ongoing deployment (CD) under the

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. Spring Cloud supports Spr

two services or split a service into multiple. However, this refactoring is difficult to implement if the client interacts directly with the microservices.Due to the above three problems, the way the client communicates directly with the server is seldom used in practice.Using an API GatewayGenerally, a better solution is to use the API gateway approach. API Gateway is a server or a unique node that enters the system. This is similar to the facet pattern in object-oriented design mode. API Gate

gradual perception of business and systems has changed many of the previous architectural work patterns, and it is easy to feel the importance of business experts in the process of using DDD. And if someone is hoping that the business can give the architect a clear need at once, then I suggest that students with such hope go to the architectural design discussion in person who is unfamiliar with the business area. You will easily conclude that "the b

5 years are very clear, many Java frameworks have faded out of view, such as Hibernate, Struts1, struts2, only spring is becoming more and more popular.Spring-boot: More simple than SPRINGMVC, SPRINGMVC has a large zero configuration file, such as Spring-servlet, Spring-mybatis, Spring.xml and Web. XML, these are not needed in spring-boot, only need a powerful annotation function, boot more suitable for micro-services.Spring-cloud: There are more components to support

spring.rabbitmq.host to the Docker machine IP 192.168.99.100. Implementing a message-driven microservices spring Cloud stream was built on top of the spring integration project. Spring integration extends the Spring programming model to support the well-known enterprise integration Model (EIP). The EIP defines a number of classic components that are often used in distributed systems. You may have heard of patterns such as message channels, routers, a

system. This is similar to the facade pattern in object-oriented design mode. The API Gateway encapsulates the architecture of the internal system and provides APIs to individual clients. It may also have functions such as authorization, monitoring, load balancing, caching, request fragmentation and management, and static response processing. Shows an API gateway that adapts to the current schema.　　Richardson-microservices-part2-3_api-gatewayThe API

ObjectiveIt is a long time not to write a blog, recently for a new job, relatively busy, so did not take out too much time to pay attention to my fans write some dry, someone asked me how recently did not update the blog, here to everyone sorry.So, in this article, let's explore the role of API gateways in the entire microservices distributed architecture.BackgroundWe know that in the MicroServices architec

uses 8G of memory, and after splitting into a micro-service, it only needs 5G to 6G of memory, saving at least 2G of memory.But it's not going to be that simple. One of them is responsible for providing rest APIs externally and is the most critical part of the entire system. To increase availability, they deployed 4 instances in Europe, North America, and Asia respectively. In this way, the microservices used a total of 12G of memory, so the overall

It feels good to finally have a chance to interact with some of the CRM advisors who are interested in this public number. I am glad to learn that some articles in the public number have helped the consultants solve some of the practical problems in the work. Thank you for your support, as long as the time allowed, this public number I will continue to write.And the CRM consultants chatted at lu

architecture that splits a large and aggregated business project into multiple small, discrete business modules, module-as-a-service, and RPC, using efficient protocols (PROTOBUF, JSON, and so on) between services. This split code base has the following characteristics: Each service should run as a small, standalone business module, like the Unix do one thing and does it well Each service should have no impact on other services when automating Test and (distributed) deployment Detai
