Hummmm while there might be some similarities the concept are not that close.

Cells are usually used to reduce blast radius and to force design that can scale.

It is a bit like a multi-AZ/multi datacenter architecture where however cells can share the same AS/datacenter. But nothing else.

So cells can share physical hardware but not logical components.

If you were to create a cell based architecture, you might have 9 cells over 3 AZ each using a different S3 bucket and DynamoDB table. For 9 S3 buckets and 9 DDB table in total.
