What is server ??🤔

Wait Wait Wait

I am not here to tell you the bookish definition , if 2nd class person reads this blog also can understand.

So, lets Start 🚀

Server is nothing but the PC/laptop only , But the server don’t have the UI(user interface), As pc server will have RAM,ROM,MEMORY,CPU.

Hold on not yet Finished , why no UI ??? 🤷‍♂️

Because if we add UI then it will consume more CPU and leads to the performance issue So, Then they thought like server is basically for the serving the request what is the need of the UI ?? and then removed the UI.
In most of the servers Linux kernel will be used , Because of its performance, stability, fast, open source , security .

Linux vs Windows ??🥊

Linux is kernel not a OS(operating system).
On top of that companies like RHEL , Fedora added the packages , shell , UI and made the OS.
These all are Flavors of LINUX kernel .

Windows is a Operating System

How to connect with the server through the SSH 🔑

Lets talk about the SSH
SSH protocol means , we will put the lock(server1.pub) to the server and will open with one private key(server1.pem) . 🔐
Example:

ssh-keygen -f <file_name>

Here i need to give the file name

ssh-keygen -f server1

After executing this you can see two files in your file manager

server1.pub ———> public key
server1.pem ——> private key

while configuring the server in the aws we need to upload the server1.pub file in the key value pair

So , now successfully generated the two files and configured the server in AWS

Then how can we connect ???

ssh -i <private_key_file_name> <user_nmae>@ip_address 

ssh -i server1.pem ec2-user@52.12.34.90

By using this you can connect to the server successfully !!! 🎉
