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 as many instances as you need when you need them, and stop them when you no longer need them. You can also change resources such as increasing or decreasing the performance of your instances as needed.

● Secure Cloud Server
AWS security features are available to safely host data and applications, such as instance-level security groups, network ACLs, and IAM.

● Global infrastructureYou
can use AWS's global infrastructure.By using AWS regions and availability zones (AZs), you can provide low-latency services to users around the world.

● Preset AMI
By using AMI, you can get a pre-installed OS such as Linux or Windows, as well as applications, which allows you to quickly start up your applications.

● Various instance types
A variety of different types are available, including CPU, memory, storage, and network, so you can choose the type that is best suited to each application.

● Charges based on resource usage
Charges are based on the amount of time an instance is used and the amount of data transferred, so you can use only the resources you need for the amount of time you need.

Functions combined with Amazon EC2

● Autoscaling
The autoscaling function provides the ability to automatically scale instances up or down depending on the load of the application, allowing you to quickly and automatically respond to increases or decreases in the number of users.

By installing a load balancer at the top of the load balancing

● Storage
You can attach storage services such as EBS and EFS, allowing you to store application data efficiently and securely.

● GPU Instances
GPU instances enable you to perform advanced computing tasks such as machine learning and data analysis.
