How to create a Key Pair?
Sign in to AWS Console using https://aws.amazon.com/
After successful login you will land in Dashboard. From there choose EC2. Click on Navigation bar and there you can select a region. Region need not be the location you belong to. You can choose any region irrespective of your location. But one thing to remember is that a key pair is specific to a region. That is to say, to launch an instance in the Ohio Region, your key pair must be created in same region.
After you select the region. In Navigation pane go to NETWORK & SECURITY. There you will find Key Pairs. Click on it. And then click on Create Key Pair.
You can give a name of your choice to the keypair but its good to give a name which is easy to remember.
This will automatically download a private key file with an extension .pem. Save it somewhere in your computer from where you can access it easily. This will be required to login to your EC2 in future.
