EC2 stands for Elastic Compute Cloud. EC2 is an on-demand computing service on the AWS cloud platform. Under computing, it includes all the services a computing device can offer to you along with the flexibility of a virtual environment. It also allows the user to configure their instances as per their requirements i.e. allocate the RAM, ROM, and storage according to the need of the current task.
Even the
user can dismantle the virtual device once its task is completed and it is no
more required. For providing, all these scalable resources AWS charges some
bill amount at the end of every month, the bill amount is entirely dependent on
your usage.
EC2 allows
you to rent virtual computers. The provision of servers on AWS Cloud is one of
the easiest ways in EC2. EC2 has resizable capacity. EC2 offers security,
reliability, high performance, and cost-effective infrastructure so as to meet
the demanding business needs.
AWS EC2
(Elastic Compute Cloud)
EC2 is a web
service which is provided by the AWS cloud which is secure, resizable, and
scalable. These virtual machines are pre-configured with the operating systems
and some of the required software. Instead of managing the infrastructure AWS
will do that so you can just launch and terminate the EC2 instance whenever you
want. You can scale up and down the EC2 instance depending on the
incoming traffic. The other advantage of AWS EC2 is that you need to pay only
for how much you use it is like the pay-as-you-go model.
What is
Amazon EC2 (Elastic Compute Cloud)?
AWS offers
EC2 which is a short form of Elastic Compute Cloud (ECC) it is a cloud
computing service offered by the Cloud Service Provider AWS. You can deploy
your applications in EC2 servers without any worrying about the underlying
infrastructure. You configure the EC2-Instance in a very secure manner by using
the VPC, subnet and Security groups. You can scale the
configuration of the EC2 instance you have configured based on the demand of
the application by attaching the autoscaling group to the EC2 instance. You can
scale up and scale down the instance based on the incoming traffic of the
application.
The
following figure shows the EC2-Instance which is deployed in VPC.
Use Cases
of Amazon EC2 (Elastic Compute Cloud)
The
following are the use cases of Amazon EC2:
- Deploying Application: In the AWS EC2
instance, you can deploy your application like .jar,.war, or .ear application
without maintaining the underlying infrastructure.
- Scaling Application: Once you deployed your web
application in the EC2 instance know you can scale your application based
upon the demand you are having by scaling the AWS EC2-Instance.
- Deploying The ML Models: You can train and deploy your
ML models in the EC2-instance because it offers up to 400 Gbps), and
storage services purpose-built to optimize the price performance for ML
projects.
- Hybrid Cloud Environment: You can deploy your web
application in EC2-Instance and you can connect to the database which is
deployed in the on-premises servers.
- Cost-Effective: Amazon EC2-instance is
cost-effective so you can deploy your gaming application in the Amazon
EC2-Instances.
AWS EC2
Instance Types
Different
Amazon EC2 instance type are designed for certain activities.
Consider the unique requirements of your workloads and applications when
choosing an instance type. This might include needs for computing, memory, or
storage.
The AWS EC2
Instance types are as follows:
- General Purpose Instances

Features
of AWS EC2 (Elastic Compute Cloud)
The
following are the features of AWS EC2:
1. AWS
EC2 Functionality
EC2 provides
its users with a true virtual computing platform, where they can use various
operations and even launch another EC2 instance from this virtually created
environment. This will increase the security of the virtual devices. Not only
creating but also EC2 allows us to customize our environment as per our
requirements, at any point of time during the life span of the virtual machine.
Amazon EC2 itself comes with a set of default AMI(Amazon Machine Image) options
supporting various operating systems along with some pre-configured resources
like RAM, ROM, storage, etc. Besides these AMI options, we can also create an
AMI curated with a combination of default and user-defined configurations. And
for future purposes, we can store this user-defined AMI, so that next time, the
user won’t have to re-configure a new AMI from scratch. Rather than
this whole process, the user can simply use the older reference while creating
a new EC2 machine.
2. AWS
EC2 Operating Systems
Amazon EC2
includes a wide range of operating systems to choose from while selecting your
AMI. Not only are these selected options, but users are also even given the
privilege to upload their own operating systems and opt for that while
selecting AMI during launching an EC2 instance. Currently, AWS has the
following most preferred set of operating systems available on the EC2 console.
- Amazon Linux
- Windows Server
- Ubuntu Server
- SUSE Linux
- Red Hat Linux
3. AWS
EC2 Software
Amazon is
single-handedly ruling the cloud computing market, because of the variety of
options available on EC2 for its users. It allows its users to choose from
various software present to run on their EC2 machines. This whole service is
allocated to AWS Marketplace on the AWS platform. Numerous software like SAP,
LAMP, Drupal, etc are available on AWS to use.
4. AWS
EC2 Scalability and Reliability
EC2 provides
us the facility to scale up or scale down as per the needs. All dynamic
scenarios can be easily tackled by EC2 with the help of this feature. And
because of the flexibility of volumes and snapshots, it is highly reliable for
its users. Due to the scalable nature of the machine, many organizations like
Flipkart, and Amazon rely on these days whenever humongous traffic occurs on
their portals.
Pricing
of AWS EC2 (Elastic Compute Cloud) Instance
The pricing
of AWS EC2-instance is mainly going to depend upon the type of instance you are
going to choose. The following are the pricing charges on some of the
EC2-Instances.
- On-Demand Instances: The
On-Demand instance is like a pay-as-you-go model where you have to pay
only for the time you are going to use if the instance is stopped then the
billing for that instance will be stopped when it was in the running state
then you are going to be charged. The billing will be done based on the
time EC2-Instance is running.
- Reserved Instances: Reversed
Instance is like you are going to give the commitment to the AWS by buying
the instance for one year or more than one year by the requirement to your
organization. Because you are giving one year of Commitment to the AWS
they will discount the price on that instance.
- Spot Instances: You have to
bid the instances and who will win the bid they are going to get the
instance for use but you can’t save the data which is used in this type of
instance.
