 What is the primary Amazon EC2 point?

A) Managed database service

B) Applications virtual servers.

C) Activities in monitoring network traffic.

D) Storing files and backups

The basis of AWS on the virtual servers is Amazon EC2 (Elastic Compute Cloud), which allows hosting instances (vitual servers) in the cloud. EC2 allows customers to start, provision and scale servers on-demand, selecting the operating system, all the way up to CPU and memory. They are used to execute applications or to host web sites or do more intricate data processing without necessarily having to buy or maintain physical equipment.

Key EC2 Components:

Example A virtual server in AWS, which can be scaled to various workloads and sizes.

AMI (Amazon Machine Image): Pre-set templates that allow one to easily launch a server with the necessary operating system and software.

Security Groups: Virtual firewalls that regulate traffic that flows in and out of your instances to provide extra security.

Elastic IP: Can be assigned to any instance using a static IP address to ensure reliable access.

EBS Volumes: Data storage and backup volumes which are persistent disk storage and are attached to EC2 instances.

The scalability of EC2 gives you the freedom to run anything, be it a small web site, or a large application- and only pay as you go, with scaling easily available in the event of a demand change. Knowledge of EC2 is necessary in the development, deployment and scaling of applications within AWS.
