. MicroServices first emphasize the small scale of services and ease of scaling and expansion of services, but this can also lead to fragmentation of services and challenges to personnel management.2. MicroServices are a distributed system, each of which has its own database, although to a certain extent increases the overall reliability of the application, but also inevitably brings a lot of redundant data

MicroServices Architecture Practices-do you know that Docker and spring boot are enough?author of cloud Hair has been concerned about 2017.02.27 02:50* words 2613 Read 2583 comments 6 likes 2 MicroServices do not exist alone, in order to better implement the micro-service architecture, the need to integrate many components mix-and-match use, can op

triggers the package compilation through Jenkins, automatically generates the version number, which triggers the automated test deployment and automated testing, a one-click Deployment Upgrade after the test, support for upgrade failure auto-rollback, and so on. We have now implemented automated packaging and test deployment, and the follow-up process is advancing.Q:openresty The session management has been processed, will developers feel inconvenient?A: Before the introduction of the

What is micro-service?The traditional single service architecture is a separate service package, sharing code and data, development cost is high, maintainability, scalability is poor, technology transformation, cross-language cooperation is relatively difficult. While the MicroServices architecture emphasizes that a service is responsible for a business, the service can be deployed separately, the technology is selected and developed independently, th

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

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

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

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.

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

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. This series of tutorials"MicroServices" easy to fix springcloud Micro Service catalog

All the way, what a wonderful journey! It took several months to complete the articles. The first article, published at the end of 2017, is now half past 2018, and I'm just writing the last article in the series. It took me a lot of time and energy to write this series of articles. This is a daunting task for me, first of all because I have a general understanding of the various parts of the knowledge, in fact, part of the original purpose of writing these articles is to improve my understanding

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 will be the late micro-service landed very b

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

With the individuation of user demand and the shortening of product life cycle, the micro-service architecture is the inevitable direction of future development of software software architecture towards flexibility, expansibility, scalability and high availability. At the same time, the popularity of container virtualization technology represented by Docker will greatly reduce the cost of implementation of microservices, and provide a solid foundation

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

MicroServices architecture: "De-centric" governance technology and data management. As an architectural approach, the various practices of DDD, including the recently popular event storming (incident storm), are actually progressive perceptions that facilitate business and system architecture grooming. In a DDD workshop, a colleague gave the words "you don't even know the business story, do you need to co

a single service. If the design is good, other services can achieve application-level fault tolerance through the mechanism of retry and smooth degradation.(2) Some shortcomings of the microservices architecture1. Complexity of distributed systemsAs a distributed system, microservices introduce complexity and several other problems, such as network delay, fault tolerance, message serialization, unreliable
