EC2 launch

  • As the memory usage of VS code on mate core is over 1G, we need to install at least t2.small
    • vscode + file browser(Caja) + terminal + chrome browser(2 open tabs) + Htop
  • t2.small looks just manageable for small java test program.
  • t2.medium is recommended...

Htop on t2.small
