What is AWS EC2, and How Does It Work? A Beginner’s Guide

Its extensive and varied collection of services is provided by its EC2 cloud platform.

Amazon EC2 is undoubtedly one of the most popular services in AWS. It allows users to launch and manage server instances anytime, for as short or long as they wish.

What is AWS EC2, and what are its benefits?

Amazon EC2 lets users launch virtual servers quickly and manage security, cookies, and networking via a simple dashboard. Organizations can develop applications faster using this scalable capacity without investing in hardware.

What is Amazon’s importance?

Amazon EC2 is an important service for many reasons. It offers users on-demand, scalable computing resources available to run multiple applications.

Amazon EC2 can also launch and manage virtual servers (VPS), making them an ideal web hosting platform.

Types of AWS EC2 instances

It is important to distinguish between virtual and physical instances when discussing instances.

Amazon has allocated a server called a p hyperinstance. This server is available in the real world to host your applications.

In contrast, a virtual server is a live server simulation. Virtual instances can be run on top of physical instances. They can be used for testing or developing applications.

General purpose

This virtual machine is designed to handle a variety of tasks. These instances are designed to provide CPU cores in large numbers as well as storage and on-demand memory.

This instance is commonly used for testing and developing software and hosting web servers.

They can be used for many other purposes which don’t require high-powered CPU cores.

GPU optimized

These instances allow you to run graphics-intensive programs faster than traditional EC2 servers.

Graphic processing units are used for design and gaming.

Linux distributions use GPUs to run graphic user interfaces. This increases compression speeds and improves the speed of database queries.


These instances can be used for large-scale data applications that require a lot of processing power in the AWS cloud.

These instances are designed to run high-performance, data-intensive, and computational applications. They require extensive availability, fast network speeds, high output/input operations per sec, and high availability.

These applications include financial, scientific, and simulation computer-aided learning, business Intelligence , enterprise-level data warehouses, and financial modeling.

Optimized storage

These storage instances are ideal for apps that require high I/O performance.

They are also well-suited for intensive memory applications, such as log processing and data warehouse analytics.

Storage-optimized instances offer high sequential read/write performance for large data storage and high-traffic websites.


This example uses solid-state drives that are extremely fast for super-fast data access.

This memory-optimized instance works well for apps that require more memory and less power, such as real-time big-data analytics and open database sources.

Micro instances

These can be used in applications with limited throughput.

Micro instances can store smaller data as an application platform or for testing software.

Spot instances

This allows users to request additional EC2 capacity at a cost they are willing to pay.

Spot instances are given to users at a reduced cost if there are new EC2 instances within the AWS region.

It is suitable for flexible applications dealing with intermittent interruptions like batch processing, containerized loads, high-performance computing (HPC) and test & Development processes.
