Baidu Elasticsearch(BES) is a hosting service that allows you to easily deploy, operate and expand in Baidu AI Cloud. Elasticsearch is a very popular open source distributed retrieval and analysis engine. You can create and configure the BES cluster within several minutes through the Baidu AI Cloud management console. The service automatically detects and replaces the failed Elasticsearch nodes, reducing the costs associated with self-managing infrastructure and Elasticsearch software. BES cloud service is fully compatible with the Elastosearch open source API, facilitating zero-cost migration of your existing Elastosearch business. Meanwhile, BES cloud service provides a privilege management mechanism, for you to freely configure the cluster privileges, so as to further ensure data security.
