smartstack

divided into three evolutionary stages (see figure below). The first stage, each service recount, handles the external communication on its own. In the second phase, all services communicate using a unified class library. In the third phase, the service is no longer concerned with communication details, all to the side of the car process, as in the TCP/IP protocol, the application layer only need to transfer the content to tell the TCP layer, by the TCP layer is responsible for all content to s

First, the basic introduction of consulConsul is an open source tool launched by Hashicorp to implement service discovery and configuration for distributed systems. Compared with other distributed service registration and discovery schemes, such as Airbnb's Smartstack, Consul's solution is more "one-stop", with built-in service registration and discovery Framework, distributed consistency Protocol implementation, health check, Key/value storage, multi

discovery are particularly important to avoid unnecessary service interruptions. The topic of service discovery has been mentioned many times and is indeed constantly evolving. Now, I will introduce some open-source or frequently-discussed solutions in this field and try to understand how they actually work. Specifically, we will focus more on the consistency algorithms of each solution, whether it is strong consistency or weak consistency, runtime dependency, and the integration choice of the

the global: need to describe how many IP addresses, what is deployed on each IP, the dependencies in each configuration file are statically determinedProblem 3, the action is very difficult to get right: This deployment script cannot be tested. Many times running on an empty machine will hang up, but running on my machine is a success.Problem 4, running too slow, and unreliable: need to download a bunch of things from the extranet, very slow. Even without downloading, running a bunch of apt-get

it should encapsulate many common patterns such as the client's speed limit, break-out protection, connection pooling, and so on, like a server package. It should also integrate with the Service Discovery module and work properly in different transports ways. A reference to the implementation is: Finagle, Ribbon and so on. As you can see, the client and server packages should be able to share code, such as connection pooling, speed limit, request tracing, etc. Service Discovery (Services discov
