Amazon EC2 stands for Amazon Elastic Compute Cloud.
It is a service from Amazon Web Services AWS that lets you rent virtual computers on the internet instead of buying physical servers.
Think of Amazon EC2 like this:
Instead of buying a physical server and keeping it in your office.
you rent a powerful computer/server in Amazon’s data center,
use it for as long as you need,
then turn it off when you are done.
You only pay for what you use.
What EC2 actually gives you
Amazon EC2 provides virtual machines called instances.
Compute
The virtual machine itself. This is the instance type that gives you CPU memory and Storage
The disks attached to the instance. Usually Amazon EBS for operating system and data.
Networking
The connectivity. This includes VPC, subnets, security groups, and IP addresses.
Each instance can have
CPU power
Memory RAM
Storage
Network
Benefits of using Amazon EC2
Fast to start
You can launch a server in minutes. No buying hardware and no waiting.
Pay only for what you use
You pay by the second or hour. Turn it off and you stop paying.
Scales easily
Need more power or more servers. Resize or add them instantly.
Very reliable
Runs in AWS data centers with built in redundancy and uptime.
Full control
You choose the OS, CPU, memory, storage, and network settings.
Secure by default
Security groups, firewalls, IAM, and encryption are built in.

Connects easily to databases, load balancers, storage, and monitoring tools.
Good for any workload

EC2 lets you run servers fast, safely, and only pay when you need them.
