It is beneficial to use `tmux` for the usage of `autossh` to create a terminal session, in which `autossh` can run without blocking the whole terminal session. Use `yum install tmux` for the installation.

Autossh itself relies on `ssh` and passes its terminal arguments to `ssh`. There are a few exeptions, for example the -M argument, which specifies the monitoring and echo port needed for the operation of `autossh` (uses the specified port and the port + 1). Autossh can be configured via environment variables, refer to the `autossh` manual for further information (`man autossh`).

Our default region in AWS EC2 is eu-west-1 (Ireland). Tests are currently run in the otherwise unused region eu-west-2 (London). Most regular operations can be handled through the AdminConsole's "Advanced / Landscape" tab. See, e.g., [https://security-service.sapsailing.com/gwt/AdminConsole.html#LandscapeManagementPlace:](https://security-service.sapsailing.com/gwt/AdminConsole.html#LandscapeManagementPlace:). Some operations occurring not so frequently still require more in-depth knowledge of steps, manual execution of commands on the command line and some basic Linux understanding. This also goes for [highest-scale set-ups requiring an AWS Global Accelerator with or without Geo-Blocking through AWS Web Application Firewall (WAF) with Web ACLs](https://wiki.sapsailing.com/wiki/info/landscape/olympic-setup#setup-for-the-olympic-summer-games-2020-2021-tokyo_aws-setup_global-accelerator).

# Thoughts on Landscape Configuration for Paris 2024 / Marseille

As a baseline we'll use the [Olympic Setup](/wiki/info/landscape/olympic-setup). The major change, though, would be that instead of running a local on-site master and a local on-site replica we would run two master instances locally on site where one is the "shadow" and the other one is the "production" master.
