Hello everyone.
Recently we see an increasing number of requests for deleting unused snapshots for mongodb database and also unused AMI in tvlk-prod account. To increase product team agility and allow self-service for this kind of request, Site-Infra decided to give access for PDA to delete particular EC2 snapshots and AMI with designated product domain tag exist, see this decision logs.
You can use the following tools to detect unused mongodb snapshot in tvlk-prod account, and delete the ones belongs to your product domain.
