However, in the Serverless lens of the Well-Architected Framework, it focuses much more on recovering from misconfigurations and transient network issues. In traditional architectures this process might be handled by your operations team, which would make sure that your virtual machines and databases were being backed up, then annually restore those backups to a separate datacenter. RDS Proxy - You can use Amazon RDS Proxy to allow your applications to pool and share database connections to improve their ability to scale.
