Wouldn’t it be great to remove the “it works on my machine” scenario? Don’t you have better things to do with your time then manually configure systems? In this live, hands-on demonstration Matt will introduce you to the concepts of Infrastructure as Code and Automation; show you how we to use Chef to develop and test system configuration locally, and then deploy them to a production environment in Microsoft Azure.

3. “DevOps
is
a
cultural
and
professional
movement.
Period.
That’s
it…
There’s
no
technology,
you
can’t
patent
‘devops’.”

4. DevOps
can
be
summarized
with
CAMS
–
Culture,
Automa?on,
Measurement,
and
Sharing.
All
are
important.

5. Managing
complexity
–
two
worlds.
Ops
starts
by
making
with
the
clicky
clicky,
and
dev
starts
wri?ng
some
code

6. We
get
a
li6le
be6er
–
ops
keeps
some
notes,
and
the
devs
test
things
on
a
dev
server.

7. Hey,
let’s
put
our
notes
into
a
wiki
and
start
sharing
with
the
rest
of
ops!
And
devs
start
sharing
with
each
other
via
version
control.

8. Now
ops
starts
wri?ng
some
scripts
to
some
kind
of
repeatability,
and
devs
get
QA
involved

9. I
know!
Let’s
use
golden
images

10. Golden
images
are
not
the
answer.
Gold
is
heavy.
It’s
hard
to
transport.
Its
hard
to
mold.
And
easy
to
lose
configura?on
detail.

11. This
won’t
scale
or
let
you
move
fast.
There’s
no
feedback
loop
from
ops
to
dev,
and
the
devs
aren’t
coordina?ng
with
ops

12. What
is
Chef?
Open
Source
Framework
for
managing
complexity
Declara?ve
language
for
describing
&
configuring
infrastructure
An
awesome
community
of
professionals
A
fast-­‐growing
company
based
in
Sea6le,
WA

13. How
does
Chef
work?
Ensures
desired
state
by
con?nually
tes?ng
and
repairing
individual
resources
in
the
system
You
compose
policies
using
a
series
of
simple
declara?ons
The
Chef
client
fetches
those
policies
from
a
central
server
and
applies
them
to
the
local
machine
The
state
of
the
machine
is
recorded
and
sent
back
to
a
database,
where
it
is
indexed
for
search,
repor?ng,
and
audit.

14. Infrastructure
as
Cod
in
a
nutshell:
Define
Policy
That
Describes
Your
Infrastructure
An
Autonomous
Agent
Implements
Your
Policy
Policy
Enforcement
is
Con?nuous
and
Safe
Automate
All
Your
Infrastructure
at
Scale

15. Build
Anything!
Simple
internal
applica?ons
Complex
external
applica?ons
Worksta?ons
Hadoop
clusters
IaaS
infrastructure
PaaS
infrastructure
SaaS
applica?ons
Storage
systems
You
name
it

16. And
manage
it
simply:
Automa?cally
reconfigure
everything
Linux,
Windows,
Unixes,
BSDs
Load
balancers
Metrics
collec?on
systems
Monitoring
systems
Cloud
migra?ons
become
trivial

17. DevOps
is
a
Two-­‐Way
Street
It’s
great
when
developers
care
about
Up?me!
Scaling!
Deployment!
Put
them
on
call!
etc.
etc.
etc.

18. How
can
we
work
TOGETHER?

19. Ops
has
as
much,
or
MORE,
to
learn
from
dev.
