Hello, and welcome to this quick lecture, where I will introduce you to AWS AppConfig. This service is newly in scope for the AWS Certified Developer - Associate exam, so I wanted to give you a quick overview of this service and what it does.

AWS AppConfig is part of AWS Systems Manager and allows you to control when and how to deploy feature flags and other updates to applications running in AWS, while also providing the ability to monitor an application's health and performance. With AppConfig, you can create different application configurations that help ensure that your applications are always running in a desired state and that changes are made in a controlled, predictable manner.

AppConfig allows you to organize and manage a set of related configuration data for your application that can then be applied to one or more environments, such as development, staging, or production. An environment serves as a deployment group for target instances and can integrate with CloudWatch Alarms to roll back any configuration changes if an alarm is triggered during a deployment to that environment.

AppConfig allows you to create configuration profiles for your application, which can include things like feature flags, connection strings, or other application-specific parameters. Configuration profiles allow you to apply updates to a specific set or even a specific percentage of instances before rolling them out to your entire fleet. This allows you to test and validate changes that could potentially cause customer impact or even downtime before they are applied to the entire application.

AppConfig also provides additional features that include:

  • The ability to validate a configuration’s format and values before deployment, ensuring all changes are in the correct format and do not contain any errors, and

  • The ability to track and roll back configuration changes, allowing you to recover from any issues that may occur during a deployment.

So to recap, AWS AppConfig is designed to help developers easily and safely deploy application updates to AWS, while also providing a simple and powerful tool for configuring, monitoring, and troubleshooting them.

I hope you’ve enjoyed this quick introduction to AWS AppConfig. Thanks for joining me, and best of luck on your certification journey!
