Difference between EC2 and AWS Lambda that every AWS learner should know!!!

Most of the Beginners (including me (;) faced the issue to understand the two services of AWS

1.AWS EC2 instance

2.AWS Lambda

Let us Understand it one by one with example

AWS EC2 instance is a service provided by AWS which aims to provide a Virtual server according to the developer needs. That means, there is no need to add a physical server or there is no need for an organization to invest in capital expenses. You only pay for the resources that you use

Lets take one example to get to know about it

Assume that you want to build your home from scratch. you have already planned where your bedroom will be, your living room, balcony, bathroom, kitchen and.... you can also add any number of rooms/bedrooms. The infrastructure of your house which also includes the size of the house will be depending on your needs. The most important part you only pay for that particular services provided by the construction people.

the same concept goes with EC2 instance. you only need the infrastructure you can customize your machine like what type of RAM should be installed, Operating System (Image) , network settings, security settings, etc.

Without worrying about use of Physical infrastructure you can directly deploy your application with pay as you go.

AWS Lambda

An AWS lambda is a serverless and event-driven service which allows you to run a code only when it gets triggered by either scaling up or scaling down.

The real world example for this could be the motion sensing light bulb in a room. when there is no one in the room the room will be dark but as soon as the sensor detects the motion of a person (when a event occurs) then the light bulb is turned on in the room and remains on until there is again no motion detected.

Instead of again again keeping track of load on your instances you basically can use AWS Lambda by writing a code to scale up or scale down according to the load on your instances.
