Per effettuare un attacco:
`vegeta attack -duration=5s -rate=10 -targets='input.txt' | tee resultsUser.bin`

o semplicemente:
`vegeta attack -duration=5s -rate=2 -targets='input.txt' | vegeta report` (per visualizzare direttamente il report)

il file input.txt sarà cosi (per efficienza scegliere solo una richiesta)

Create a LightSail instance
During creation, remember to change the region
when using a specific region a private key will be created

download the key
you can use the `ssh -i path/to/key user@host`
or you can add the private key (without the .pem extension) inside your .ssh folder, then
edit the config file with the user, url and path to the private key

to copy a file into lightsail, do not log into ssh, but use `scp /path/to/file user@host:./path/where/to/copy`
