A Raspberry Pi cluster also allows you to learn Docker, Kubernetes, Serverless. Or how to turn all the cluster nodes’ resources into one supercomputer with the help of simultaneous processing software like OpenMPI.
Can you SSH from anywhere?
On the client, we can use any remote login tool to start a SSH connection to the server. In this example, we use putty.exe to connect to a SSH server. We simply set the IP address of the target server and check the ‘SSH’ option. Clicking on ‘open’ will initiates a SSH connection.
