Regions.getCurrentRegion() for AWS SDK 2.0

Question

From this link: https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/migration-client-region.html
Regions.getCurrentRegion() is still not supported for AWS SDK 2.0. So what is the alternative that we could do in order to get the region of our cluster.

Answer

`Regions.getCurrentRegion()` does not have an equivalent in v2.

You could use the [`DefaultAwsRegionProviderChain`](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/regions/providers/DefaultAwsRegionProviderChain.html) class that looks for the region in this order:

1. Check the `aws.region` system property for the region.
2. Check the `AWS_REGION` environment variable for the region.
3. Check the `{user.home}/.aws/credentials` and `{user.home}/.aws/config` files for the region.
4. If running in EC2, check the EC2 metadata service for the region.

```java
var regionProvider = DefaultAwsRegionProviderChain.builder().build();
var region = regionProvider.getRegion();
```
