Change AWS EC2 Instance Type

If we face hardware limitations of our EC2 instance, we can not just increase Memory/CPU cores as in VMWare, instead, we must change instance type. It is set of predefined images with different hardware specifications.

First, stop EC2 instance:

Seclect instance>>Actions>>Insatnce State>>Stop

Then, from Actions>>Instance Settings>>Change Instance Type

Select instance type from drop-down menu and click Apply

Now start the instance. and check changes.

Connecting to AWS VM (instance) from Linux Machine

In the last post, we connect to aws instance from windows machine now we will connect to it from Linux machine by Terminal

First of all, give permission 400 to pem key file

chmod 400 /home/ubuntu/serverkaka.pem

Open Terminal and Type

ssh -i /home/ubuntu/serverkaka.pem ubuntu@34.239.44.197

Here /home/ubuntu/serverkaka.pem is a path of my pem key file and 34.239.44.197 is my aws instance IP.

Now you connect with AWS instance

Connecting to AWS VM (instance) from Windows Machine

In the last post, we created Linux instance, and downloaded private key (serverkaka.pem) now we will connect to it from Windows by PuTTY

Download PuTTY from here

Run PuTTYgen to convert pem file to ppk, so we can import it into PuTTY

Click Load Button and Choose .pem file

Now PuTTYgen successfully imported pem file click OK and Save private key

If you want to set passphrase click No and set it, otherwise, click Yes

Then save keys with .ppk extension

Now note down or copy your VM's public IP

Open PuTTY and give IP and Port and expand SSH>Auth and Browse .ppk file and click Open Button.

Click Yes when it's asking for PuTTY Security Alert

Now you successfully connected with your Linux AWS VM instance.

During instance creation, I created basic security rules in security group for SSH access only to VM’s IP to any address (0.0.0.0/0)
