There are more than one server, and there is a reason to try the cloud operating system.
Mesos is often well known for its mature cases in large-scale production environments. But in fact, Mesos is also very useful for internet startups. The most notable point is that the Mesos-based cloud operating system was used fro
balancing, both for Web servers and middleware servers, and for transparent access without changing configuration.

Reset: This operation is used to initialize your cloud server's system, if the server already has data must pay attention to backup. The reset operation is based on the system disk and the data disk. Resetting the system disk will initialize the system disk status of the cloud serv
After the introduction of cloud computing, O M focuses not only on the normal operation of the previously managed devices, but on the smooth network, we will also focus on active resource supply, automatic configuration, sustainability, and traceable real-time configuration management.
In traditional O M management, in order to ensure reliability and scalability, you must not only support the deployment phase, but also monitor the running status of
typically loads the configuration file from "Spring.config.name" like the Spring boot application, equivalent to the {application} parameter, while "Spring.profiles.active" is equivalent to {profiles} Parameters. The precedence rules for a profile are the same as in regular boot applications: The active profile takes precedence over the default configuration, and if there are multiple profiles, the last profile wins (such as adding entries to the map).For example, a client application has this

The server provides resource-based HTTP for external configuration (name-value pairs or equivalent yaml content). The server can be easily embedded in the spring boot application using @enableconfigserver annotations. So this application is a configuration server:Configserver.java@SpringBootApplication@EnableConfigServerpublic class ConfigServer { public static
