AWS customers can now compare any two application configuration versions side by side within AWS AppConfig, a feature of AWS Systems Manager. This new functionality highlights the differences between the changed configuration values in the two versions, and helps Developers and Devops professionals to understand how their configuration data has changed over time. This adds additional safety features when deploying the intended configuration values to mitigate the risk of any application outages.

AWS AppConfig makes it easy for AWS customers to quickly roll out application configurations across applications hosted on Amazon Elastic Compute Cloud (Amazon EC2) instances, containers, AWS Lambda, mobile apps, IoT devices, and on-premises servers in a validated, controlled and monitored way.

When deploying a new configuration change using AWS AppConfig, Developers and DevOps professionals update or add configuration values within the configuration file and save those changes as a new version of the configuration file. In order to mitigate any risk of application outages after deployment, it is a best practice to manually review the difference with the previous version. With this launch, customers, who store configuration data as AWS AppConfig hosted configurations or retrieve their existing configurations from Amazon S3 and AWS Systems Manager Documents, can easily compare any two versions of a configuration within the management console.
