Question 35. What Is Public Key Credentials And How To Install It ?

Answer :

Amazon EC2 uses public–key cryptography to encrypt and decrypt login information. Public–key cryptography uses a public key to encrypt a piece of data, such as a password, then the recipient uses the private key to decrypt the data. The public and private keys are known as a key pair.

After configuring the AMI to prevent logging in using a password, you must make sure users can log in using another mechanism.

Question 31. How You’re Charged In Amazon Ec2? Explain In Detail ? Answer : Charges varies upon AMIs backed and storage volums. AMIs backed by instance storage charged for: AMI storage + Instance usage AMIs backed by Amazon EBS storage charged for: Volume storage + Usage in addition to the AMI + instance usage When an Amazon EBS-backed instance is stopped, you are not charged for instance usage, but you are still charged for volume storage. AWS charges a full instance hour for every transition from a stopped state to a running state, even if we transition the instance multiple times within a single hour. For example:  if hourly instance charge for your instance is $0.10 and if you were to run that instance for one hour without stopping it, you would be charged $0.10. If you stopped and restarted that instance twice during that hour, then you would be charged $0.30 for that hour of usage (the initial $0.10, plus 2 x $0.10 for each restart).
