Rally 简介
Rally 集成了部署、API测试、压力测试功能(如下图)，但我们一般用 devstack 部署，tempest 做 API 测试，因此 Rally 常用于模拟高并发场景的压力测试。Rally 测试 openstack 在并发下 API 的相应时间和请求成功率，从而测试出 openstack 规模和性能。

3. Benchmark Openstack Peformance
rally/doc/samples/tasks/scenarios/ 包含各个组件的配置文件，直接使用即可，举例：
1）测试 keystone 创建-删除用户性能 $ rally -v task start rally/doc/samples/tasks/scenarios/keystone/create-and-delete-user.json
$ rally -v task start rally/doc/samples/tasks/scenarios/nova/boot-and-delete.json
