EC2 Instances Secure connection.
Amazon EC2 (Elastic Compute Cloud) is an AWS service that allows users to rent virtual servers in the cloud. However, gaining access to these instances requires a secure method of communication. In this comprehensive guide, we will discuss the process of connecting to your AWS EC2 instance using SSH for Linux and PuTTY for Windows.
Launching an EC2 Instance
1.Go to the search bar and search, ec2.
Click on launch instance.
Give your server a name and choose Ubuntu, free tier eligible in the application and OS images.
For the instance type, choose the free tier. Under key pair, click create new key pair and store this file securely as this file will be used to connect to the server securely using ssh.
Click create key pair.
In Networks section, under the security policy, click the checkbox to ensure you receive traffic from HTTP and HTTPS, then click on launch instance.
