Host in Geoweaver

What is Host?

In Geoweaver, Host means computing machines (Linux/Windows/Mac computers). It is where the code gets executed, data gets processed, and history is generated.

Mostly, Host is dedicated to the local machine where Geoweaver is installed. Once Geoweaver is started, it will add a default Host Localhost which means the current machine Geoweaver is sitting on. For most people, Localhost is all they need. They can run all their processes on Localhost.

Geoweaver has an amazing feature that’s a lifesaver for multiple-server users. It allows you to enroll these servers and run your code on them without the hassle of having to manage it all separately. AWS EC2 instances and HPC are perfect examples of servers you can easily integrate with Geoweaver, and you’ll be able to benefit from its time-saving benefits.

This tutorial will help how to enroll a new Host and make it ready for running processes in Geoweaver.

Supported Hosts

Linux/Win/Mac Computers

Geoweaver provides a Host category called Linux/Win/Mac Computers to manage all the local/remote machines.

Tips: SSH, or Secure Shell, is a remote administration protocol that allows users to control remote servers over the Internet. It provides a mechanism for authenticating a remote user, transferring inputs from the client to the host, and relaying the output back to the client.
