篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了云功能比较相关的知识，希望对你有一定的参考价值。
阿里云、AWS 、Azure云的比较mysql数据库：
和原生的MySQL实例相比，AWS多了部分rds开头的表
和原生的MySQL实例相比，Azure China mysql库隐藏了很多的表，比如 user slow_log
和原生的MySQL实例相比，Azure 全球 mysql库没有隐藏表，和原生实例一致
和原生的MySQL实例相比，阿里没有隐藏表，但是user和db表无法直接访问，但是提供了视图
information_schema数据库：
和原生的MySQL实例相比，阿里多了一些表
和原生的MySQL实例相比，Azure China 和原生实例一致
和原生的MySQL实例相比，Azure 全球和原生实例一致
和原生的MySQL实例相比，AWS中国多了2张表，AWS全球和原生实例一致
视图：
和原生的MySQL实例相比，阿里多了3张视图： db_view，slow_log_view，user_view，Azure和AWS都没有
存储过程：
和原生的MySQL实例相比，AWS中国和全球都提供了

和原生的MySQL实例相比，Azure 全球：

+-------+--------------------------------------+
| db | name |
+-------+--------------------------------------+
| mysql | az_add_action_history |

| mysql | sp_upgrade_firewall_rule |
| mysql | sp_upgrade_replica_information_table |
+-------+--------------------------------------+
13 rows in set (0.20 sec)
和原生的MySQL实例相比，Azure中国：
mysql> select db,name from mysql.proc ;
+-------+---------------+
| db | name |
+-------+---------------+
| mysql | az_kill |
| mysql | az_kill_query |
+-------+---------------+
2 rows in set (0.03 sec)
和原生的MySQL实例相比，阿里没有提供存储过程，和源实例保持一致，不能通过命令行做主从，只能通过界面完成

MySQL的Super权限能干什么?super权限是包含在ALL里面的
比较重要的功能限制有：
1、change master to
2、set binlog_format,sql_log_bin,sql_log_off
3、purge binary logs ,执行一些binlog相关的语句
RELOAD权限能执行 flush-logs flush-hosts的操作
PROCESS权限能show processlist 和查看information_schema
REFERENCES 可以创建外键
EXECUTE 执行权限
重要的参数对比：
log_bin ：
Azure中国开log_bin;Azure全球区默认不打开log_bin ，阿里和AWS都是开的
