-- t2.small
-- 100 GB hard disk (you need to edit the Storage tab before launching the instance; by default it comes with just 8GB. It can be lower -40GB- if you are not planning to test the K8s appliance)
-- before launching the instance, please open the ports defined above by editing the Security Groups as per the picture. This can also happen after launching the instance following `this guide <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/authorizing-access-to-an-instance.html>`__.
