    We used centos and Plesk Panel and when removing a subdomain, a mysql database that belonged to another domain was accidentally removed. We have already checked Backup and unfortunately the database in question is not listed. However, we believe there may be a way to recover recently deleted files on linux and in this case the tables are files. So we would like to know if there is any possibility of this restore. If yes, we urgently need to hire this Job

    We want to leave several old perceptions behind and be radical in the move to the cloud, see drawing. Therefore I would like to talk to an expert about options on migrating an on premise architecture into the cloud in the best way possible. Candidates need to have a proven migration background in similar projects. Special topics to be discussed are: - Strategy aka "the why" - Prerequisites to move - Administration & security - Azure AD only, getting rid of AD - project timeline - migration sequence Session will be held in teams / teams whiteboard. Native German or English language is a plus.
