Log Service:Select a network type

Network type

• Alibaba Cloud internal network: The Alibaba Cloud internal network provides gigabits of shared bandwidth. Transmission of log data over the internal network is stable and fast. The Alibaba Cloud internal network includes virtual private clouds (VPCs) and the classic network.

• Internet: Transmission of log data over the Internet is limited by the network bandwidth. In addition, network issues such as jitters, latency, and packet loss may affect the speed and stability of data transmission.

• Global acceleration: This network type can be used to accelerate log collection by using the nodes of Alibaba Cloud Content Delivery Network (CDN). Compared with the Internet, global acceleration provides a more stable network with lower transmission latency.

Select a network type

• Internal network

  You can use the Alibaba Cloud internal network to transmit log data from an Elastic Compute Service (ECS) instance to a Simple Log Service project. Examples are provided in the following two scenarios:

  • The ECS instance and the Simple Log Service project belong to the same Alibaba Cloud account and reside in the same region.

  • The ECS instance and the Simple Log Service project belong to different Alibaba Cloud accounts but reside in the same region.

  We recommend that you create a Simple Log Service project in the region where the ECS instance resides. Then, you can collect logs of the ECS instance and send the logs to Simple Log Service over the Alibaba Cloud internal network.

• Internet

  You can use the Internet to transmit log data from an ECS instance or server to a Simple Log Service project. Examples are provided in the following two scenarios:

  • The ECS instance and the Simple Log Service project reside in different regions.

  • The server is provided by a third-party cloud service provider or deployed in your self-managed data center.

• Global acceleration

  If your servers are deployed in your self-managed data center outside China or provided by a third-party cloud service provider outside China, you can enable global acceleration. Global acceleration can resolve stability and latency issues during data transmission over the Internet. For more information, see Global acceleration.

① If your server is an ECS instance that belongs to another Alibaba Cloud account, a server that is provided by a third-party cloud service provider, or a self-managed data center, you must first install Logtail on the server before you can collect logs from the server. Then, you must specify the ID of the Alibaba Cloud account for which Simple Log Service is activated as a user identifier on the server. This way, the Alibaba Cloud account can use Logtail to collect logs from the server. For more information, see Configure a user identifier.
