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 microservi

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.

The change in state needs to be an atomic operation, that is, when it is called concurrently, it can be executed only once. You can use distributed locks, or optimistic locking CAS operation implementations. Specification of service splitting five: interface data definition strictly forbidden embedded, tr

Analytic microservices Architecture Series The article will describe the definition, characteristics, application scenarios, evolution of enterprise integration architecture and micro-service transformation thinking and technical decision-making considerations in several sections, and take IBM technology as an example to introduce how to realize the transformation of micro-service architecture.

that branch. After the bug is fully repaired, you need to merge the code on the hotfix branch into the develop branch and the master branch at the same time.For the version number we also have requirements, in the format: x.y.z, where x is used for significant refactoring will not be upgraded, Y is used for new features to be released when the upgrade, Z used to modify a bug before the upgrade. For each micro-service, we need to strictly follow the above development model to execute.Micro-Servi

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. Spring Cloud supports Spr

application development. Soon after 10 years, Martin Fowler and ThoughtWorks, British architect James Lewis, sat down together to analyze several large and complex systems that could continue to evolve, summarizing 9 core traits, It then uses microservices to define the architecture that holds these traits. Since then, Google, Netflix, Amazon and a range of star enterprises are the seat, MicroServices bega

anywhere, because the deployment itself already contains all the necessary components.Micro services are small enough. However, the definition of "small" is very subjective. You can use some estimation methods such as line of code, function point, use case, and so on. In general, however, there is no definite link between "small" and size. In building microservices, the author Sam Newman gives some techniq

With the introduction of several core components from the previous spring cloud, we have been able to build a short (imperfect) microservices architecture. As shown in the following example:We implemented service registries and service registration and discovery using the Eureka in spring cloud Netflix, while service consumption and balanced workloads across the ribbon or feign through the spring cloud Config enables the application of multi-environme

The previous article talked about the microservices infrastructure, and Netflix's many open source components together provide the complete distributed microservices infrastructure environment, whileSpring Cloud is a further encapsulation of Netflix's many open source components, and it also achieves a good integration with the cloud platform and the spring Boot development framework.Spring Cloud is a relat
