Amazon VPC   allows   to launch the Aws   resources   into a virtual network that we have defined. If we have a default VPC we can skip this section. Create a Security Group. We can create a   non-default   VPC in our account using the below steps.

As the AWS services like Amazon EC2 are accessed using the provided credentials when we access these services it will check whether we have the permissions to access the resources the  console  asks for the password. We can create the access keys to access the AWS account from command line or API interfaces. But for the security reasons Amazon will not recommend that to access the AWS account using the credentials which we created while the  Sign  UP. For that Amazon recommends to use the IAM  (  Identity and Access Management) instead. To create an IAM user and then add the user to an IAM group with administrative permissions and grant the user with administrative permissions we can access AWS using the special URL and credentials for that IAM user.

If you'd like to keep your instance for later, but not incur charges, you can stop the instance now and then start it again later. To terminate your instance In the navigation pane, choose Instances. In the list of instances, select the instance. 1.  Choose Actions, then Instance State, and then choose Terminate. 2.  Choose Yes, Terminate when prompted for confir...
