Here are 12 little-known secrets about Linux, which prove that Zamlin's statement is not exaggerated, so Linux is a often forgotten operating system, but in fact it has always been the OS that people rely on, but people don't realize it.

Android, the very popular mobile operating system, uses Linux as a base, and today, as many as thousands of Android devices are activated every day, this is closely related to Linux.

IntroductionIn large and medium-sized distributed systems, often the system relies on a lot of dependencies (HTTP,HESSION,NETTY,DUBBO, etc.), under high concurrent access, the stability of these dependencies on the system is very large, but the dependency has a lot of uncontrolled problems:such as slow network connection, resource busy, temporarily unavailable, service offline and so on.Under normal circumstances:When dependent service I busy, other dependencies are normal:I block, the thread po

The "bounded" context, which does not require the surrounding parts of each service-other services, dependent services, etc., the team focuses only on the service itself and the API of the service; Traditional application requirements need to be understood and designed to be developed, and microservices can be started faster by the team

It's also easier to use. Consul is implemented with Golang and therefore has natural portability (support for Linux, Windows, and Mac OS X); the installation package contains only one executable file for easy deplo

Netflix is in the process of using zookeeper, we have encoun

About Spring Cloud:Spring Cloud provides developers with some common patterns for quickly building distributed systems (such as configuration management, service discovery, circuit breakers, intelligent routing, micro-proxies, control buses, one-time tokens, global locks, leading elections, distributed sessions, cluster status). The coordination of distributed systems has led to boiler plate mode, and the use of spring cloud developers can quickly stand up to implement these patterns of services

Spring Cloud is an ordered collection of frames. The development of the spring boot model simplifies the development of a distributed system infrastructure, and can be started and deployed in a one-click fashion with spring boot development. Spring Cloud combines today's more mature, proven service framework with the spring boot style for re-encapsulation, masking complex configuration and implementation principles, and ultimately integrating a simple, easy-to-deploy and maintainable Distributed
