The build produces two sets of binaries - one set that falls under the Elastic
License and another set that falls under Apache License Version 2.0. The
binaries that contain `-oss` in the artifact name are licensed under the Apache
License Version 2.0.

Apache Lience允许使用者修改和重新发布代码(以其他协议形式)，允许闭源商业发布和销售。

但是，ES公司的产品中都包含x-pack部分，这块是elastic自己的协议，该部分主要是为产品加一层安全保护，涉及到数据安全的问题。

基础许可是永不过期的，但是没有安全管理、机器学习等功能。

ELK能做哪些事情？
