quote

All services implements command quote.

This command allow to estimate cost of service.

Quote service ec2

> paws ec2 quote -r eu-west-1 -i m3.medium --lease 1yr --upfront partial

Monthly fees:
  Linux/UNIX (Amazon VPC), m3.medium reserved instance applied
   └─  0.027 USD * 730 (Hrs) = 19.710 USD

One-time initial fees:
  Upfront Fee
   └─  211.000 USD

Total:

└─ Total Monthly: $19.71 /month
└─ Initial Fee: $211.00
└─ Smoothed monthly: $37.29 /month

Here smoothed monthly is Total Monthly + Initial fee / (leasing duration * 12)

Quote service s3

> paws s3 quote -r eu-west-1 --volume 16Go

Monthly fees:
  $0.023 per GB - first 50 TB / month of storage used
   └─  0.023 USD * 16 (GB-Mo) = 0.368 USD

Total:

└─ Total Monthly: $0.37 /month

Paramaters tips To? Go? Ko? hours ? minutes? Don't worry with units! When you use parameters, PAW convert with the invoicing unit used by AWS

Paws understand suffix bellow :

• bytes: Kb, Mb, Gb, Tb, Pb, Eb, Ko, Mo, Go, To, Po, Eo, K, M, G, T, P, E
• duration: d, h, m, s
• ops/s: /d, /h, /m, /s

e.g.:

--storage 8Go
--duration 45h
--reads 10/s

Important: To estimate cost, paws load pricing file from aws. Some files (like ec2) are heavy and may take time to load. Be patient, files are put in local cache /tmp/paws

Quote from yml file

Speed up your cost estimation and quote from a simple yaml file !
