Notice: for the following parameters to take effect, the instance needs to be stopped and changes need to be applied before restarting the instance.
The following table shows a sample of constraints that are required in the definition of the study, depending on the tuned parameters.
Notice that AWS does not support all combinations of instance types and sizes, so it is better to specify them beforehand in your constraints to avoid unnecessary experiment failures.
To limit the combination of the instance type and sizes to those only supported by AWS or to those of interest for a particular study you can use a constraint such as the following:
This constraint is built by connecting multiple constraints such as the following one with the OR operator ||
These constraint instruct akamas to only use large, xlarge and 2xlarge size for instances of type c5.

cpu_util | percent | The average CPU utilization % across all the CPUs (i.e., how much time on average the CPUs are busy doing work) |
network_in_bytes_details | bytes/s | The number of inbound network packets in bytes per second broken down by network device (e.g., wlp4s0) |
network_out_bytes_details | bytes/s | The number of outbound network packets in bytes per second broken down by network device (e.g., eth01) |
disk_read_bytes | bytes/s | The number of bytes per second read across all disks |
disk_write_bytes | bytes/s | The number of bytes per second written across all disks |
aws_ec2_disk_iops_reads | ops/s | The per second average number of EBS IO disk-read operations summed across all disks |

aws_ec2_instance_type | Categorical |
|
| yes | Instance types comprise varying combinations of CPU, memory, storage, and networking capacity, optimized to fit different use cases |
aws_ec2_instance_size | Ordinal |
