It goes over creating a named profile to store your AWS credentials and using appSettings… Read More »Custom Metrics to AWS CloudWatch from ASP.NET Core

One of the aspects I love about .NET Core is the new configuration and options pattern. In a continuation from my last post on using AWS Parameter Store for Data Protection keys, you can imagine it is possible to use Parameter Store for .NET Core Configuration. Amazon.Extensions.Configuration.SystemsManager There is a package by AWS that facilitates making using Parameter Store incredibly easy. Simply add the Amazon.Extensions.Configuration.SystemsManager package to your project and use the AddSystemsManager extension method on IConfigurationBuilder The argument you pass to AddSystemsManager will be the prefix to your configuration hierarchy within Parameter Store. In my example, I’m using /Demo… Read More »Using AWS Parameter Store for .NET Core Configuration
If you’re using ASP.NET Core in AWS under any type of load balanced scenario, either through Elastic Beanstalk or an ALB with and ECS, etc, you will need to share the data protection keys. This is because each instance of your application needs to be using the exact same keys. This isn’t an issue if you are using a single instance as the keys will be stored in memory. If you haven’t yet used the AWS SDK, I highly recommend first checking out my quick start on configuring AWS SDK in ASP.NET Core.
