Got StackStorm !
Every automation looks like a nail

What SHOULD be automated?
From: Practice of Cloud System Administration, by Thomas Limoncelli

What HAS BEEN automated with StackStorm
• Security checks
– On malware detection in a VM, isolate
network port on a switch
• App blue-green deployment
– On Jenkins tests passed, bring new vm
claster, deploy and configure app, set
loadbalancer to send % of traffic to new
app, monitor, roll forward, or back out
• Networking
– On BGP peer goes down: collect
troubleshooting data, post on slack &
create JIRA ticket
– On Link aggregation member error,
check load, if capacity of rest of LAG
bundle enough, disable link with error
• OpenStack
– orphan VM clean-up: On orphans
detected, shut down, email owner, keep for
few days, delete
– VM evacuation on HW failures: On host
RAID failure, get list of impacted VMs,
email VM owners, evacuate VMs, create
JIRA ticket for hardware replacement.
• Service remediation:
– Cassandra “node down” recovery: On ring
node dying, deploy new node, configure,
add to the ring.
– Remediating RabbitMQ, Galera cluster,
MySQL, and more…

Benefits
• Reduce MTR (Mean Time to Resolution)
• Avoid failures (fixing on computer time, not human time)
• Reduce risk of human error (no fat fingers)
• Positive team impact
– Avoid pager fatigue and team burn-out
– Turn from reactive to proactive (break reactive vicious cycle)
– Capture operational knowledge – as code

Network Automation
Now supporting Multiple Vendors

Device support
Proven approach from cloud compute space

NAPALM
AUTOMATION
Packs
PYTHON
BINDINGS
INTEGRATION
PACKS
DEVICE / OS
INTERFACES
Some workflows [1] leverage unique device functions, so they
call actions of the device’s integration pack.
Other workflows [2] need to be abstracted and treat devices
alike (e.g. IXP provision on mixture of SLX and MLX). So they
use “unified” Napalm pack.
device drivers
Integration packs expose device configurations and operations
as st2 actions. VDX and SLX packs will expose most/all of
device functionality. MLX is “best effort”. Napalm integration
pack provide “unified” device actions, just like libcloud does in
“compute” domain.
While integration packs can call device interfaces directly,
python bindings provide reuse, and abstract device OS
versions. PyNOS binds VDX via netconf. SLX and MLX don’t
exist yet.
Napalm is Open source project that exposes a unified python
API to interact with different network devices via device drivers.
Devices expose various interfaces: RESTCONF, NETCONF,
CLI/TELNET, SNMP.

Workflows Better in Operations
• Simple to define, reason, visualize
• Transparent
– state is clear, execution is trackable: running, complete, failed steps
• Reliable
– Workflows are long-running
– Crash tolerance
– “Restart from point of failure”

Why not legacy Runbook Automation?
• Microsoft System Center Orchestrator
• HP Operation Orchestrator
• Cisco Process Orchestrator (CPO)
• VMWare vCO / vRealize
They do not DevOps

Infrastructure As Code
Leverage social coding and collaboration

Designed for Devops

Infrastructure as code
Case Study
• Service Catalog backed up by workflow
• Automate provisioning on VMW/OpenStack, 4 Data centers
• Before: CPO, operator updates via GUI, click and pray, x4
• After: StackStorm, dev -> code review -> staging -> QA-> prod
