 In 2023, Spyder received a [Chan Zuckerberg Initiative](https://chanzuckerberg.com/) Essential Open Source Software for Science [Cycle 5 grant](https://chanzuckerberg.com/eoss/proposals/enhancing-spyder-ide-remote-support-for-scientific-research-in-python/) to implement a new remote development architecture and features in Spyder to allow users to develop and run code in remote servers and cloud machines.
 After a six-month search by Spyder lead maintainer Carlos Cordoba to find the right candidate to engineer the backend and network architecture for this project, he found me, so I joined the core development team near the end of 2023.

 The plugin connects to the machine, installs the server, and creates SSH tunnels for the exposed server and extra APIs implemented by `spyder-remote-services`.
 Once that's complete, Spyder will be able to automatically create remote [IPython Consoles](https://docs.spyder-ide.org/current/panes/ipythonconsole.html) on behalf of users.
 Furthermore, you can now stop remote computations and restart remote kernels, which was not possible before.

 To cover all those requirements, I created the [`@AsyncDispatcher` decorator](https://github.com/spyder-ide/spyder/blob/v6.0.0/spyder/api/asyncdispatcher.py#L39) function, which starts a thread to run an async loop if needed, schedules the async function in a specific loop, and returns a future object with the async function's result.
 That result is emitted in a Qt signal which is then used by Spyder synchronously to perform other tasks (e.g. check if the server is running).

 Our plans for the next feature version, [Spyder 6.1.0](https://github.com/spyder-ide/spyder/milestone/134), include adding the necessary APIs to `spyder-remote-services` so it can manipulate the remote file system.
 This will allow you to view, copy, move and delete remote files and directories right from Spyder's Files pane.
 Users will also be able to create and manage local and remote Python environments, so they can work in different scientific and programming projects remotely at the same time.

 Finally, we plan to enable connecting to an already running JupyterHub instance, for situations where the user's organization already has one set up that they want to work with using Spyder.
 The changes required will be relatively straightforward since instead of talking to our own server for remote development, users will communicate with the existing JupyterHub instead.
