The most reliable and time-efficient solution for transferring the company's environmental data from the on-premises data center to Amazon S3 securely can be achieved using AWS DataSync.
AWS DataSync is a managed data transfer service that simplifies and accelerates moving data between on-premises storage systems and AWS storage services like Amazon S3. It encrypts data during transfer and provides options for using AWS Identity and Access Management (IAM) roles to control access to the S3 bucket.
