I am migrating AWS CDK CloudfrontWebDistribution construct to Distribution Construct but as per docs CDK will delete and recreate the distribution, I want to know how much time this whole process will take? what is the downtime I will have?

docs for reference -> https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_cloudfront-readme.html#migrating-from-the-original-cloudfrontwebdistribution-to-the-newer-distribution-construct

CodePudding user response：

The downtime can be anywhere from minutes to hours. It all depends on the how your clients use the CloudFront distribution.

I'd recommend proceeding in the following steps:

1. Create a brand new distribution, using your new CDK constructs. Keep the old one running.
2. Swap the DNS name used by your clients. And wait for them to be updated
3. Kill the old distribution
