Description This paper introduces a service discovery and configuration sharing software, briefly introduces the principle and use of consul, a small text, hoping to attract interested children's shoes together to explore research. What's consul? Consul is a service software that supports distributed and highly available service discovery and configuration sharing in multiple data centers, developed by Hashicorp company in Go language, and is open so

Consul is a service software that supports distributed, highly available service discovery and configuration sharing in multiple datacenters, developed by Hashicorp in the Go language, and open source based on the Mozilla Public License 2.0 protocol. Consul supports health checks and allows the HTTP and DNS protocol call APIs to store key-value pairs.

, it still needs to be managed manually, but future terraform will join these support. Q: are each VPC group fully independent of service delivery? Can you say what aspect of the business layer this technology is dealing with? A: Each VPC group provides a complete application feature implementation, which also improves the prd-sg-master,prd-sg-slave that we can use for disaster tolerance. The business layer provides primarily HTTP services and internally dependent MicroServices.

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-data c

)}log.Printf("%d * %d = %d", args.A, args.B, reply.C)} Consul Consul is an open source tool launched by Hashicorp to implement service discovery and configuration for distributed systems. The consul is distributed, highly available, and horizontally scalable. It has the following features: Service Discovery: Consul provides a way to register services and discovery services through DNS or HTTP interfaces. Some external services can easily find t

GO Scheduler is to allocate multiple OS threads so that they can use goroutine smoothly when running on one or more processors. In the process of multi-threaded operation, work sharing and work stealing often occur simultaneously. Starting with Go 1.1, Golang core developer Dmitry Vyukov has uploaded a scheduler for go work-stealing algorithms. This paper will further explain the principle of go work-stealing algorithm scheduler, and how to implement the function of scheduler with Go language.
