 You can monitor your I/O consumption in the Azure portal (with Azure Monitor) using [IO percent](./concepts-monitoring.md) metric. If you need more IOPS than the max IOPS based on compute then you need to scale your server's compute.
 
 ## Autoscale IOPS
-The cornerstone of the Azure Database for MySQL - Flexible Server is its ability to achieve the best performance for tier 1 workloads, which can be improved by enabling server automatically scale performance (IO) of its database servers seamlessly depending on the workload needs. This is an opt-in feature that enable users to scale IOPS on demand without having to pre-provision a certain amount of IO per second. With the Autoscale IOPS featured enable, you can now enjoy worry free IO management in Azure Database for MySQL - Flexible Server because the server scales IOPs up or down automatically depending on workload needs.

 With Autoscale IOPS, you pay only for the IO the server use and no longer need to provision and pay for resources they aren’t fully using, saving both time and money. In addition, mission-critical Tier-1 applications can achieve consistent performance by making additional IO available to the workload at any time. Autoscale IOPS eliminates the administration required to provide the best performance at the least cost for Azure Database for MySQL customers.
