The Spring Cloud project, which implements various patterns including service discovery, makes it easy to automatically register a service instance with Eureka.
此外,由于自动扩缩、故障与升级,整组服务实例会动态变更。
Moreover, service instances change dynamically because of auto-scaling, failures and upgrades.
有关详细信息,请参阅如何将AzureAPI管理服务实例部署到多个Azure区域。

现在我们已经了解服务注册中心的概念,接下来让我们看看服务实例是如何被注册到服务注册中心。
Now that we have looked at the concept of a service registry, let's look at how service instances are registered with the service registry.
此外,由于自动扩展、故障与升级,整组服务实例会动态变更。

如果在整个林中的计算机上安装多个服务实例,则每个实例都必须具有自己的SPN。
If you install multiple instances of a service on computers throughout a forest, each instance must have its own SPN.
为了完成一次请求,代码需要知道服务实例的网络位置(IP地址和端口)。
In order to make a request, your code needs to know the network location(IP address and port) of a service instance.
因为无状态,可以直接堆叠新服务实例及用硬件负载均衡实现扩展。
Being stateless, scaling could be achieved by spinning up new instances of any of the services and using hardware load balancers between them.
Istio使服务实例之间的通信变得更灵活、可靠、快速和安全。
Istio makes communication between service instances flexible, reliable, fast and secure.
SOA则支持更动态地发现服务实例,来提供请求者所期望的接口、语义和服务保证。
An SOA supports more dynamic discovery of service instances that provides the interface, semantics and service assurances that the requestor expects.
服务注册中心可能会调用服务实例的健康检查API来验证它是否能够处理请求。
