Since the company already usesIAM Identity Center, the lowest-overhead and most consistent design is to manage access throughpermission setsassigned to groups. AWS documentation explains that permission sets are the central mechanism IAM Identity Center uses to grant least-privilege access to AWS accounts and resources. This approach fits team-based access for development, testing, and operations without having to manage individual IAM users in each account. It also aligns with AWS guidance to apply least privilege by creating restrictive permission sets instead of broad standing permissions. The other options either introduce more manual identity management or create unnecessary account complexity for the scenario described. (AWS Documentation)

============

To meet the requirement of deleting objects older than 3 years while retaining certain data, this solution leverages serverless technologies to minimize operational overhead.

S3 Inventory: S3 Inventory provides a flat file that lists all the objects in an S3 bucket and their metadata, which can be configured to include data such as the last modified date. This inventory can be generated daily or weekly.

AWS Lambda Function: A Lambda function can be created to process the S3 Inventory report, filtering out the objects that need to be retained and identifying those that should be deleted.

S3 Batch Operations: S3 Batch Operations can execute tasks such as object deletion at scale. By invoking the Lambda function through S3 Batch Operations, you can automate the process of deleting the identified objects, ensuring that the solution is serverless and requires minimal operational management.

Why Not Other Options?:

Option A (AWS CLI script on EC2): Running a script on an EC2 instance adds unnecessary operational overhead and is not serverless.

Option B (AWS Batch): AWS Batch is designed for running large-scale batch computing workloads, which is overkill for this scenario.

Option C (AWS Glue + script): AWS Glue is more suited for ETL tasks, and this approach would add unnecessary complexity compared to the serverless Lambda solution.

The best solution to query and filter S3 data directly without downloading the full object is to use Amazon Athena.

Amazon Athena is an interactive query service that lets you use SQL to analyze structured, semi-structured, and unstructured data directly in Amazon S3, without needing to move or transform the data.

It supports formats like CSV, JSON, ORC, Parquet, and Avro and integrates with AWS Glue Data Catalog for schema management.

Athena is serverless, meaning there’s no infrastructure to manage, and it ' s billed per query, which keeps it cost-effective.

Option B (EMR) is heavier and requires managing a cluster.

Option C (API Gateway) is not suited for querying S3 datasets.

Option D (ElastiCache) is a memory store, not a query engine.
