engine (no separate Web server required), the service should start on its own at the command line, and be accessed immediately through the exposed HTTP port.Concurrency: To initiate more micro-service instances to scale horizontally when demand increases.Can be arbitrarily disposed of: you can start and stop as needed.The development environment is equivalent to the production environment: minimizing the gap between all the environments in which the service runs.LOG: Use the tool to log and vie

This article introduces the use of Docker and kubernetes to build a set of MONGODB services with redundant backup sets, from the container to the CI and CD-initiated changes, discussed the container technology to MONGODB challenges and opportunities, and then how to deploy a stable set of MONGODB services , very dry.IntroducedWant to try to run MongoDB on your laptop? Want to execute a simple command and then have a lightweight, self-organizing sandbo

gateway itself, or by external caches such as Redis or memcached. By returning cached data or default data, API gateway ensures that system errors do not affect the user experience.Netflix Hystrix is a very useful library for implementing remote service invocation code. Hystrix records those calls that exceed the pre-set limit values. It implements the circuit break mode, which allows the client to stop in an endless wait for unresponsive services. If the error rate of a service exceeds the pre

exceeds a specific threshold. It implements a "circuit breaker (Circuit breaker)" mode that prevents clients from waiting unnecessarily for unresponsive services. If the error rate of the service exceeds the set threshold, then Hystrix initiates the breaker, and all requests fail immediately and last for a certain amount of time. Hystrix allows a user to define a backup operation after a failed request, such as reading data from the cache, or returning a default value. If you are using the JVM,

architecture"? To put it simply, a microservices architecture is to split a complete application from the data store vertically into multiple different services, each of which can be deployed independently, independently maintained, independently scaled, and invoked between services and services through, for example, restful APIs.For the "micro-service Architecture", we can find a lot of relevant introduction and research articles on the Internet to

. NET core has been released for a long time, because in recent years the main use of Java, so has not used. NET core, today there is a C # written demo, need to make a service, do not want to go to Java to implement, consider using. NET core to taste fresh, the goal is to develop a micro-service, It is then deployed to a Docker swarm cluster for other applications to invoke.Environment preparation Download

the above properties must be configured in the bootstrap.properties config section to be loaded correctly. Because the configuration of config will precede application.properties , and bootstrap.properties the load is before application.properties . Create a REST API to return the From property of the configuration center, as follows: Configure @Value("${from}") the From property in the service by binding.Launch the app and access: Http://localhost:7002/from,
