splunkconf‐backup cost optimisation with tag and frequency

Introduction

Cost will vary depending on :

• AWS region
• your AWS discount
• backup frequency
• storage class (by default STD is used for hourly then IA for other backups)
• number of instances to backup
• role and content on each instance

Cost simulation

This cost simulation is done on a test environment with :

• one SH with ES app on it and multiple addons plus a few apps
• one DS
• one MC
• one CM (which also push ML librairies to idx layer)
• idx cluster

backup sizes in MB

instance type	State backup in MB	etc targeted backup in MB	kvdump backup in MB
CM	267	15.8	0.018
MC	1.3	44.3	0.020
SH	292	2500	6000
DS	4.3	20.5	.001

backup frequency

backup frequency is the one from default terraform values

instance type	nb hourly STD	nb daily IA	nb weekly IA	nb monthly IA
CM	60	60	10	12
MC	60	60	10	12
SH	60	60	10	12
DS	60	60	10	12

This is 2880 STD PUT per month and 144 IA PUT per month

Amount of data to store (GB per month)
