Public
clouds
ü IaaS:
Most
desirable
for
workloads
with

of
variability
v AXrac8on:
Apparent
“infinite”
capacity;
Elas8city
ü SaaS:
Most

9. Efficient
Architecture
and
Design
Low
cost
architectures
ü Loose
coupling
across
layers
and
components
v Each
component
is
replaceable
(commodi8zed)
ü Leverage
commodity
components
ü Design

failures
Right

10. Efficient
Opera7ons
Efficient
opera7ons
=
Automa7on
ü Automa8on
requires
standardiza8on
Common
approach:
Standardize
on
services
ü Constraining:
Limits
innova8on
and
agility
ü Mostly
feasible
at
lower-­‐levels
(e.g.,
infrastructure)
ü Standardiza8on
at
applica8on
or
higher
levels
are
elusive
Novel
approach:
Standardize
on
knowledge
ü Capture,
formalize
and
disambiguate
tacit
knowledge
ü Standardize
ways
to
automate
services
using
knowledge
ü Challenge:
Maintain
currency
of
knowledge
v Maintain
and
improve
knowledge
through
con8nuous
learning
