[theshanbhag]

MongoDB's legacy implementation for Private service connect required 50 service attachments; With latest changes we can create the same using one load balancer.

Thank you for your pull request! Here is a review of the changes.

PR Title

The PR title currently does not follow the repository conventions. It should be short, capitalized, imperative, and have no trailing dot (e.g., no Conventional Commits prefixes).
Please update the title to something like:
Update MongoDB connectivity using Private Service Connect

Code Review

The changes to the MongoDB Atlas resources and the PSC address configuration look solid. I only have one minor formatting note:

fast/project-templates/data-mongodb/main.tf

• There is a missing newline at the end of the file. Please ensure the file ends with a newline character to comply with standard POSIX file formatting and Terraform linting rules.

Once the PR title and the missing newline are addressed, a maintainer will do the final review and approval. Thanks again for your contribution!
