Target customers: developers Features released: Log Service supports the OpenTracing (Jaeger) adaptation, which directly integrates the storage with the query layer and provides the following features: 1. Native Jaeger only supports storing data permanently in Cassandra and Elasticsearch. You must maintain the stability of the backend storage system and adjust the storage capacity. With the massive data processing capabilities of Alibaba Cloud Log Service, Jaeger on Log Service provides an easy-to-use way for you in distributed tracing, saving your efforts on the backend storage system. 2. Jaeger UI only supports querying and displaying traces, without enough support for problem analysis and troubleshooting. With Jaeger on Alibaba Cloud Log Service, you can quickly identify problems in the system by using the supreme query and analysis capabilities of Log Service. 3. Compared with Jaeger, which uses Elasticsearch as the backend storage, Log Service supports the Pay-As-You-Go billing method at 13% of the cost of other options (See Self-built ELK vs. Log Service). With this feature, you can enhance the tracing log analysis capabilities by simply using Log Service, without modifying codes.
