Updates to WATcloud Infra - Introducing Login Nodes

[Yuvraj Singh Birdi]

Hello everyone, today we're introducing a new type of node—login node—into our cluster. These help us simplify the cluster architecture significantly, which will lead to fewer maintenance sessions that directly impact users. The new machines are wato-login1 and wato-login2. We will deprecate and disable the current general-use machines (delta-ubuntu2, tr-ubuntu3 and derek3-ubuntu2) and Bastion on 2025-06-15. These machines are meant as simple entry points to the cluster for submitting jobs to compute nodes. They have no docker, or local storage, similar to our Bastion node. Access instructions have been updated to be in line with these changes, please refer to the user manual here (). Migrating to this new architecture for users is as simple as just replacing the old machines with the new ones in your ssh config (i.e., replacing tr-ubuntu3 with wato-login1). If your team has hard-coded machine names, please remember to update those as well. Sincerely, WATcloud Team
