SLS or SST for services?

On this page it is explained “Originally when SST was released, it was meant to be a way to use CDK alongside your Serverless Framework apps. While you can still do that. SST’s Live Lambda Development makes it a first-class dev environment for serverless apps.
So you don’t have to use Serverless Framework together with SST. Soon we’ll also have a migration guide to help you move over your Serverless Framework projects to SST.”.

It makes me confused.
We plan to use serverless for service layer for a production application that we will maintain several years.

What is the official recommendation : to use serverless for service layer and SST for infrastructures, or to use SST for services and infrastructures (because serverless will be deprecated and not the official recommendation in a near future) ?

The webpage has been updated, now there is no mention about “Soon we’ll also have a migration guide to help you move over your Serverless Framework projects to SST”.

What does it mean ? No answer and the sentence that made me confused was deleted, what should I understand ?
It’s even more confusing…

Hey @Patchoulin sorry I didn’t see this before. SST and Serverless Framework are two separate open source frameworks for building serverless applications. SST is based on AWS CDK and allows you to test your Lambda functions live. The docs that you linked to are from SST and not related to Serverless Framework.

Hope that helps.
