Amazon EC2 is a computing service provided by AWS as a virtual server. Servers are managed in units called instances, and new instances can be created by simply clicking a few buttons on the browser or issuing a command from the CLI (command line interface). Therefore, compared to physical servers (on-premises), the preparation period for server machine procurement can be significantly shortened.

Amazon EC2 features

● Scalable computing resources You
can start as many as you need when you want to use them, and stop them when they are no longer needed. Additionally, you can change resources such as increasing or decreasing the specs of instance performance as needed.

You can use the security features of the secure cloud server For example, you can use instance-level security groups, network ACLs, and IAM.

● Global infrastructure
You can take advantage of AWS's global infrastructure. By using AWS Regions and Availability Zones (AZ), you can provide low-latency services to users around the world.

● Preset AMI
By using an AMI, a preset OS such as Linux or Windows and applications are provided with them already installed. This allows applications to start quickly.

● Various instance types
A variety of different types are available, including CPU, memory, storage, and network, so you can choose the most suitable type for each application.

● Billing based on resource usage Pay-as-
you-go billing 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.

Features combined with Amazon EC2

● Autoscaling
By using the autoscaling function, instances can be automatically scaled up or down depending on the application load. This allows you to quickly and automatically respond to increases or decreases in the number of users.

●
By installing a load balancer on top of a load balancing network, you can distribute traffic to multiple instances and expect to improve application availability and scalability.

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

● GPU Instances
You can use GPU instances to perform advanced computing tasks such as machine learning and data analysis.
