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

attention to testing. More importantly, they discover exceptions in the production environment through monitoring, and then quickly roll back or take other necessary actions. However, you need to pay special attention to the scenarios that are especially concerned about risk avoidance and supervision or production environment errors will have a significant impact. Selection of microservice Architecture In the right project, the right team, using the microservice architecture will benefit

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.

number of legacy applications, so when it comes to the urgent task of needing to meet business needs faster and better, most of the time the enterprise will not build a completely new application, usually the enterprise refactoring the existing application or want to try to reuse the existing code. Evolution to a microservices architecture typically involves the following phases: 1. Traditional SOA service transformation; 2. The introduction of some

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.

large number of microservices can be more complex. Basically splitting requires following several principles: The single principle of responsibility: "To bring together things that change for the same reason, to separate things that change for different reasons". This principle is adopted to determine the micro-service boundary. Team Autonomy principle: The larger the team, the higher the cost

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

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.

challenge for every business, so that the industry has begun to summarize this model as a responsive enterprise (responsive Enterprises), Most of the principles summarized in the model are designed to better adapt to the high complexity of environmental uncertainties. Separation of complexity from a business perspective The complexity of each person's ability to perceive is limited, and in the face of high complexity we do the separation of concerns
