microservices vs serverless

IntroductionEnterprises are increasingly implementing cost savings, solving deployment problems, and improving DevOps and production operations by using containers. by creating products such as Azure container service, Azure service Fabric, and partnering with industry leaders such as Docker, Mesosphere, and Kubernetes, Microsoft has released Windows and LinuxInnovations in containers. These products provide a container solution that helps companies build and deploy applications at the speed and

Building a Hystrix dashboard in spring cloud is very simple and requires only the following four steps:Create a standard spring boot project named: Hystrix-dashboard.Edit Pom.xml, depending on the content as follows:To apply the main class plus @enablehystrixdashboard, enable the Hystrix dashboard feature.@EnableHystrixDashboard@SpringCloudApplicationpublic class HystrixDashboardApplication {public static void main(String[] args) {SpringApplication.run(HystrixDashboardApplication.class, args);}}

Create a basic spring boot project, named Eureka-server, and introduce the required dependencies in the Pom.xml:Start a service registry with @enableeurekaserver annotations to provide conversations to other apps. This step is very simple, just add this annotation to a normal spring boot application to enable this feature, such as the following example:@EnableEurekaServer@SpringBootApplicationpublic class Application {public static void main(String[] args) {new SpringApplicationBuilder(Applicati

Spring cloud itself provides a lot of components, but we need to follow the business model to customize the enterprise needs of the common architecture, then we need to consider what technology to use now?Below I have made the following technical summary for the spring Cloud Micro-service distributed cloud architecture, hoping to help you:View:H5, Vue.js, Spring Tag, React, AngularJsSpring boot/spring Cloud:Zuul, Ribbon, feign, Turbine, Hystrix, Oauthor2, Sleuth, API Gateway, Spring Cloud, Confi
