Is an EC2 instance a physical machine?
Ec2 instances are the virtual machines provided by AWS that you can rent to run your application workloads. They are in reality areas of a piece of physical hardware with the capability to support the compute and memory characteristics of the virtual machine EC2 instance being offered.
What is a EC2 instance in AWS?
An Amazon EC2 instance is a virtual server in Amazon’s Elastic Compute Cloud (EC2) for running applications on the Amazon Web Services (AWS) infrastructure. Users can select an AMI provided by AWS, the user community or through the AWS Marketplace. Users also can create their own AMIs and share them.
What is an instance in cloud computing?
A “cloud instance” refers to a virtual server instance from a public or private cloud network. If the server grows beyond the limits of a single machine, cloud instance computing allows the cloud software to be easily expanded to span multiple machines, whether temporarily or permanently.
Can a machine have multiple IP addresses?
Yes. A computer can have more than one ip address at a time. You can specify those ip addresses by two ways as suggested by dinesh. You can specify the additional ip address in advanced properties of your network connection.
How do I access an EC2 instance in a private subnet from the internet?
Nat Gateway: A Nat Gateway enables instances in private subnets to connect to the internet. The Nat gateway must be deployed in the public subnet with an Elastic IP. Once the resource is created, a route table associated with the the private subnet needs to point internet-bound traffic to the NAT gateway.
