1 devops-mtl2014 Infastructure documentations Flowchart,schemas and usefull informations Pierre-Luc Dion pdion@cloudops.com

2 devops-mtl2014 Overview Various type of schema Usefull Information to provide (Ops perspective) Flowchart (my favorite) Share your opinions and ideas

3 devops-mtl2014 Usefull tools for your docs Text Anything that is collaborative and can be shared and remain protected. Google apps (doc, spreadsheet, sites) wiki docuwiki confluence mediawiki sharepoint Graphs Tool you will be confortable to work with Visio Lucidchart Confluence (plugin) Lot of Visio shapes available: http://www.visiocafe.com/

4 devops-mtl2014 Schemas Separate OSI layer in different schemas Layer 2 (link layer) – physical connectivity – Ethernet Layer 3 (network layer) – IP, routing layer Layer 4 (transport layer) – Flowchart, applications communications

5 devops-mtl2014 Layer 2 example

6 devops-mtl2014 Layer 3 example

7 devops-mtl2014 Layer 4 example

8 devops-mtl2014 Valuable information in the flowChart OS type, IP, hostname Application name/type Listen port(s) init script path to log files Arrow express connection initiation (not the direction of data) Each box is an application (ex: process, webserver, database, JVM,…)

9 devops-mtl2014 event more… Hypervisor (it’s a VM/instance/Bare) NFS share if it’s required by Apps Backup: software connectivity and origin Which system USER is use to execute the app Automation system connectivity

10 devops-mtl2014 Flowchart does not contain SNMP System admin (RDP, SSH, Telnet,…) Unreleated to the application stack (system cron, system daemons) NTP Hypervisor tool (vmware tools, xentools,…)

11 devops-mtl2014 Tricks of the trade Build your own Visio Stencils (shapes) Top to bottom mean from Insecure to Secure Have a color coding for app boxes

12 devops-mtl2014 When to Start the documentation? 1.Before the project begin 2.As you learn the application stack

13 devops-mtl2014 Before the project start Based on: assumptions Known applications that will be use What it should look like Will allow you to Understand dependencies;firewall and connectivity What need to be build as infrastructure

14 devops-mtl2014 As you learn the system Allow you to validate what you understand on the application stack. Sometime it help existing team to better understand what they build and/or support

15 devops-mtl2014 Enough Time to see more examples…

16 devops-mtl2014 C’est fini Thank you Questions/Comments?
