如何向对应地域的实例服务器发送数据？

Question

假设我有三个区域(eu,us,asia)在各自的实例上托管相同的应用程序。我将只为这些相同的应用程序注册一个域名。

当用户从eu请求时，我喜欢将数据发送到eu区域应用服务器，反之亦然。

例如:user ->请求→Example.com(源自eu) ->发送数据到eu应用

例如:user ->请求→Example.com(来自我们)->发送数据给我们app

例如:user ->请求→Example.com(来自亚洲)->发送数据到亚洲应用程序

我可以通过负载平衡器或其他东西设置吗?

是的，您可以使用OCI DNS和通过地理位置流量导向策略进行流量管理。指导策略应该根据查询的大陆geokey过滤或优先考虑DNS答案。

使用ROUTE_BY_GEO模板的POST/steeringPolicies请求正文示例:

{
"compartmentId": "ocid1...",
"displayName": "Geolocations mapped to answer pools",
"ttl": 30,
"healthCheckMonitorId": "ocid1...",
