Linode is a cloud hosting platform that enables users to deploy and manage Linux-based virtual servers in the cloud. It allows users to create and configure virtual machines using a web-based dashboard, providing a range of features for managing, monitoring and scalability. Through the dashboard, users can configure the server’s CPU, RAM, and storage, as well as select from a range of Linux distributions and applications. Linode also provides a range of tools for administering the server, such as a command line terminal, file transfer, and remote access. It also includes a range of security features, such as server firewalls, encrypted backups, and two-factor authentication. The platform also allows users to quickly scale their servers as their needs change, and provides monitoring tools to keep an eye on server performance.
linode is a vps / cloud hosting provider. Sandstorm appears to be a software suite.
Sandstorm seems to be more like dropbox rather than linode. It basically provides cloud storage but no virtual machines.
