Benefits of using Amazon EC2 Instances

AWS EC2 (s) simple and easy web service interface enables the users to get and configure capability with lesser friction. It provides users with full control of their computing resources and helps them run on Amazon’s proven computing ecosystem. Amazon EC2 also minimizes the time required to obtain and boot new server instances to minutes. It also allows users to scale their capacity much faster, both up and down, as their computing needs change. The following are the benefits of using Amazon or AWS EC2.

Elastic Web-Scale Computing

Amazon EC2 enables its users to increase or decrease capacity within minutes and not in hours or days. Moreover, users can begin one, 100s, or even 1000s of server instances in parallel. Certainly, because this is controlled by using web service APIs, the user’s application can scale on automation itself up & down depending upon its needs.

Completely Controlled

Users have full control over their different instances. Further, users have root access to each instance, and they also can interact with them as they would with any system. They can stop the instance while recovering the data on their boot partition. Then can later restart the same instance with web service APIs. These instances may be rebooted remotely with APIs. Users also have access to the console output of their instances.

Flexible hosting services on cloud

The users have a choice of different instance types, OS, and software packages, etc. Amazon or AWS EC2 allows users to choose a memory configuration, CPU, instance storage, etc. And also they select the boot partition size that is optimal for their selection of operating system and app. Example: - Users selecting operating systems include several Linux distributions and MS Windows Server.

Designed to use with other AWS

The Amazon EC2 works in coexistence with Amazon Simple Storage Service (Amazon S3), Amazon Relational Database Service or Amazon RDS, and Amazon Simple Queue Service or Amazon SQS to provide a complete solution for computing, query processing, and storage across a distinct range of applications.


Amazon EC2 or AWS EC2 offers a highly reliable ecosystem for starting replacement instances speedily and predictably. Moreover, the service runs under Amazon’s proven network structure and data centers.


An Amazon EC2 works in coincidence with Amazon VPC to provide security and faster networking functions for the user's computing resources. User’s computing instances are located within a VPC with an IP range that the user specifies. Moreover, the user has to decide which instances are revealed to the internet and which will remain private.

  • The security groups and networks ACLs allow users to control inbound and outbound network access to and through their instances.
  • Moreover, users can provision their EC2 resources as Committed Instances. These instances type are Amazon EC2 Instances that run on hardware dedicated to a single customer for additional separation.
  • In case users don’t have a default VPC, then they must build a VPC. Later, they can launch instances into that VPC to usefully advanced networking features like private subnets, network ACLs, outbound security group filters, and Dedicated Instances.


The Amazon EC2 passes on the financial benefits of Amazon’s scale to users. Users pay a very low price for the computing capacity they actually consume.

Easy to start

It provides to get started quickly with Amazon EC2 by visiting the AWS Management Console and the option to choose pre-configured software on AMIs. Now, users can deploy this software to AWS EC2 through the EC2 console much faster.

Amazon EC2 features

There are various powerful features of AWS EC2 include the following:-

Amazon- EBS Elastic Block Store

Amazon Elastic Block Store offers non-stop storage for AWS EC2 instances. Moreover, Amazon EBS amounts are network-connected and carry on individually from the life of an instance. The Amazon EBS measures are highly available and highly reliable which can be leveraged as an Amazon EC2 instance’s boot partition or connected to a running Amazon EC2 instance as a principle block device. While using it as a boot partition, Amazon EC2 instances can be stopped and restarted later. Moreover, it enables us to only pay for the storage resources used while managing the instance’s status.

EBS optimized instances

To get an additional less and hourly fee, consumers can launch selected Amazon EC2 instance types as EBS-optimized instances. The EBS-optimized instances deliver exclusive throughput between AWS EC2 and Amazon EBS. It includes the options between 500 and 14k Mbps depending on the instance type used.

Optimized CPU Configurations

The CPU’s optimized feature provides users greater control of their Amazon EC2 instances on two fronts. In the first one, the user can mention a custom number of vCPUs while launching the latest instances to save on vCPU-based licensing fees.

Elastic IP-Addresses

The Elastic IP-addresses are steady IP add builds for dynamic cloud computing. An Elastic IP address is related to users' accounts, not a specific instance and the user controls that address until he selects to explicitly release it.

Amazon Virtual Private Cloud

Amazon VPC lets users providing a logically outlying section of the Amazon Web Services (AWS) Cloud where users can launch AWS resources within a virtual network that they describe.

Amazon CloudWatch

Amazon CloudWatch is a kind of web service that provides observation for AWS cloud resources and apps, starting with AWS EC2. Moreover, it provides users with visibility into resource utilization, operational execution, and overall demand patterns, etc. It also includes metrics like CPU usage, disk reads and writes, and network traffic.

Auto Scaling

Auto Scaling enables users to automatically enhance their Amazon EC2 capability up or down with relevant to conditions they define.

High-Performance Computing Clusters

Customers with difficult calculative workloads such as tightly linked parallel processes, or with apps sensitive to network execution, can achieve the same high compute and network performance provided by custom-built structures while getting benefits from the elasticity, flexibility, and price benefits of AWS EC2.

Enhanced Networking

Enhanced Networking enables users to get notably higher packet per second (PPS) execution, lower network nervousness, and slower latencies.

Auto Recovery

Auto recovery is an Amazon EC2 feature that is built to improve instance availability. Users can automatically recover supported instances when machine impairment is noticed.

Summing Up

Depending on the workload and application needs, users can select from the various Amazon EC2 instance types that this blog explains in detail. To serve different workloads, the Amazon EC2 platform keeps expanding its existing instance types with the latest releases.
