Machine Type	AWS EC2 Type	estimated cost
1 master node	t4g.xlarge	~120 USD/month
1 worker node	t4g.xlarge	~120 USD/month
SUM:		~240 USD/month

For a 1 week training period -> ~60-80 USD/week

Machine Type	AWS EC2 Type	estimated cost
3 master node	t4g.xlarge	3x ~120 USD/month
3 worker node	t4g.xlarge	3x ~120 USD/month
SUM:		~720 USD/month

For a 1 week training period -> ~180-220 USD/week

Those prices are slightly overestimated, since the cluster needs a bootstrap server (it's deleted after installation is complete), loadbalancers, EBS disk, S3 bucket, etc. and those also will cost some amount.

The default configuration for OKD installation is to deploy 3 master and 3 worker nodes, but cluster functionality, application deployment, monitoring, etc. can be used with only 1 master and 1 worker. Throughout this training the method to deploy only the required minimum resources are explained and can be used.
