AWS Systems Manager Now Supports Use of Parameter Store at Higher API Throughput

AWS Systems Manager Parameter Store now supports up to 1,000 requests per second. This lets you run applications that require higher concurrent access to a large number of parameters. You can enable the higher throughput limit from the Parameter Store Settings tab. Once the higher throughput is enabled for your account, you incur charges per API interaction. See the pricing page for details.
