Amazon has proved its might in the field of offering diverse cloud services and has excelled in almost all scenarios to date. Amazon EC2 came into play in 2006 and has gained immense popularity since then. But, along with that, AWS Lambda is also a popular service that came out in 2014 and is now walking side-to-side with EC2 in terms of popularity and adaptation.

3. A Detailed Analysis of AWS Lambda vs EC2
AWS EC2 (Amazon Web Services Elastic Compute Cloud) is a popular service
that uses EC2 instances or virtual machines within the cloud. It allows you to
change the disk space, enhance CPU performance and swell tweak memory.
AWS Lambda is a popular computing service platform that allows users to
execute defined code that is written in a Lambda understandable language that
is Python, JavaScript, or Java.
Amazon EC2 came into play in 2006 and has gained immense popularity since
then. But, along with that, AWS Lambda is also a popular service that came out
in 2014 and side-to-side with EC2 in terms of popularity and adaptation.

4. Practical Differences with Major Comparison Elements
This section is dedicated to the important comparison elements in Lambda vs.
EC2 battle that are as follows:
❖ Differences in Terms of Use Cases
❖ Difference in Terms of Working Principle
❖ Differences in Terms of Versions and Snapshots
❖ Differences in Terms of Performance and Availability
❖ Differences in Terms of Security

5. 1. Differences in Terms of Use Cases
The use cases of Amazon EC2 are:
➢ Testing applications.
➢ Developing applications.
➢ Hosting different websites.
➢ Disaster recovery attributes.
➢ High-end computing solutions.
The use cases of AWS Lambda are:
➢ It is meant to automate the specified tasks.
➢ Objects uploaded under the Amazon S3 bucket are processed within Lambda.
➢ Log analyzing is implemented in real-time with AWS Lambda.
➢ Transformation and filtering of data in real-time

6. 2. Difference in Terms of Working Principle
Under EC2, the operations are done with VMs that are also known as the EC2
instances. Along with that, it allows you to add virtual hardware such as network
interfaces, memory, virtual disks, and others to the instances.
AWS Lambda runs your application within a container that consists of libraries
and codes. The resources needed for the execution are provided by Amazon,
and the scaling is done automatically and do not have the authority to control
the running instance of EC2 and the running container of AWS Lambda.
Example;Alexa Skills Set, API Gateway, CloudFront, Kinesis, S3, SQS, SNS,and
CodeCommit.

7. 3. Differences in Terms of Versions and Snapshots
Under EC2, there is a complex snapshot system available for the Elastic Block
Storage of respective EC2 instances and the accessibility to create diverse
incremental snapshots and then turn around to the needed EC2 instance state.
AWS Lambda is embedded within a versioning system for enhanced
management of the Lambda functions with code copy can be assigned a specific
version number to which the aliases will be pointed to the respective versions of
code.

8. 4. Differences in Terms of Performance and Availability
Under EC2, the instance runs continuously after it is powered until the time you
stop it manually. If not that, then you will have to initiate a task specifying.If the
performance aspects of a particular EC2 instance permit, you can run several
applications upon it simultaneously.
AWS Lambda is quite available at all times but is not meant to run throughout
the day when it is in the default state. It activates only when a query of the
trigger is linked to a particular event. The application or Lambda function has a
maximum timeout limit of 15 minutes.

9. 5. Differences in Terms of Security
With EC2, you will have to manually configure a firewall to control the security
aspects of your EC2 instances. Amazon is offering a Virtual Private Cloud for
ensuring cloud security to the instances and maintains traffic control and
requested to manually add and configure antivirus to the EC2 instance.
Lambda has that access by default. IAM Role is implemented for defining the
services;For each function, the IAM role should be configured accordingly. Once
you have successfully configured the IAM role, you can easily connect the
Lambda function to select Amazon services.

11. Conclusion
These are a few of the practical differences that explain the importance of both
AWS Lambda and AWS EC2. Therefore, in the battle of AWS Lambda vs EC2 as
both have some flaws and superiorities over one another.
Both are best and commendable in their own ways. Therefore, consider the
differences and analyze which service is best for you to run your functions or
applications seamlessly.
