  3. aurora is cheaper to use than MySQL , MariaDB, or Postgres
    the difference is you get to use the more native engines vs Aurora

  4. I have been shortlisted for AWS DCO role (Data center outsourcing) interview in upcoming few days.

    1)How should I prepare for that specific role?
    2)Are these questions relevant?
    3)What are their further rounds?
    4)I just have an account on aws should I learn to use it?

  6. SQS should be used when communicating with different services like AWS Lambda etc. so that if it fails you still have data in the SQS.

  7. The largest single file that can be uploaded into an Amazon S3 Bucket in a single PUT operation is 5 GB. If you want to upload large objects (> 5 GB), you will consider using multipart upload API, which allows to upload objects from 5 MB up to 5 TB
