Amazon EC2 is a computing service provided by AWS as virtual servers. Servers are managed in units called instances, and new instances can be created by simply clicking a few buttons in a browser or entering commands from a CLI (command line interface). This significantly shortens the preparation time for procuring server machines compared to physical servers (on-premises)

Amazon EC2 Features

● Scalable computing resources:
You can launch only the number of instances you need when you want to use them, and stop them when you no longer need them. You can also change resource specifications, such as upgrading or downgrading instance performance, as needed.

● Secure Cloud Servers:
You can leverage AWS's security features to safely host your data and applications. For example, you can use instance-level security groups, network ACLs, and IAM.

● Global Infrastructure:
You can utilize AWS's global infrastructure. By using AWS regions and Availability Zones (AZs), you can provide low-latency services to users all over the world.

● Pre-installed AMIs
: By using an AMI, you receive a system with pre-installed operating systems such as Linux or Windows, as well as applications. This allows you to quickly launch applications.

● Various instance types
are available, including different CPU, memory, storage, and network configurations, allowing you to select the type best suited to your application.

● Billing based on resource usage:
Because billing is based on the time spent using instances and the amount of data transferred, you can use only the resources you need for the time you need them.

Functions combined with Amazon EC2

● Auto Scaling
: The auto scaling feature automatically scales instances up or down according to the application load. This allows for quick and automatic responses to increases or decreases in the number of users.

load balancing
By placing a load balancer above the

● Storage:
Because storage services such as EBS and EFS can be attached, application data can be stored efficiently and securely.

● GPU Instances
: GPU instances can be used to perform advanced computing tasks such as machine learning and data analysis.
