It is one of the most popular services by AWS, which provides rented virtual computers (called instances) under various capacities in terms of CPU, memory, disk, network, and so on where users can run and host their applications.
Getting ready
Before going ahead and launching an EC2 Instance, we will require resources we created in preceding tasks; that is, security groups and VPC (subnets).

- EC2 keypair which is a set of RSA public-private keys. It...
