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 microservice architecture. Why microservice Architect

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

This course focuses onSpark, the hottest, most popular and promising technology in the big Data world today. In this course, from shallow to deep, based on a large number of case studies, in-depth analysis and explanation of Spark, and will contain completely from the enterprise real complex business needs to extract the actual case. The course will cover Scala programming, spark core programming,

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

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

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

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

Three, in-depth rddThe Rdd itself is an abstract class with many specific implementations of subclasses: The RDD will be calculated based on partition: The default partitioner is as follows: The documentation for Hashpartitioner is described below: Another common type of partitioner is Rangepartitioner: The RDD needs to consider the memory policy in the persistence: Spark offers many storagelevel

of flexibility and low cost also show that these smaller programs can be reused in other projects to make them more efficient.Examples of several Java microservices frameworksHere are a few microservices frameworks that you can use for Java development: Spring Boot: This is probably the best Java microservices Framework, which is suitable for control in

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
