What is EC2-
Amazon is a web service that enables you to launch and manage server instances in Amazon’s data centers using APIs or available tools and utilities. We can use Amazon EC2 server instances at any time, for as long as you need, and for any legal purposes.
✓How EC2 Instance works?
Here are the steps:
Step 1: Launch Virtual Machine from AMI
Step2: Install software of that instance
Step 3: Create a new AMI
✓The Features include:
1.On Demand – It can be accessed from anywhere
2.Elasticity – It would be elastic when accessing Amazon Instances
3.Resource pulling – Amazon does multi-tenancy. In simpler terms, they would have a huge data center which they would be virtualizing and offering through various channels.
✓Amazon Machine Images (AMI)-
An Amazon Machine Image (AMI) provides the information required to launch an instance. You must specify an AMI when you launch an instance. You can launch multiple instances from a single AMI when you need multiple instances with the same configuration. You can use different AMIs to launch instances when you need instances with different configurations.
✓To connect from the Amazon EC2 console-
-Open the Amazon EC2 console.
-In the left navigation pane, choose Instances and select the instance to which to connect.
-Choose Connect.
-On the Connect To Your Instance page, choose EC2 Instance Connect (browser-based SSH connection), Connect.
