The European Project ARTIST aims to develop a set of methods and tools to aid companies in the cloudification of their applications considering technical - , business -, and organizational process – related aspects. In this talk,  the methodology and some of the tools will be shown in a practical way, as if an actual migration project was actually taking place.

3. Current Situation
Does
it
REALLY
have
to
be
THIS
way?

4. Motivation (I): Why do companies migrate?
• Maintenance
• Ad-­‐hoc
customiza9ons
(custom
code)
and
roll-­‐ups
• Technologies
obsolete
and
not
largely
supported
• Scarce
skilled
people
To
reduce
opera0onal
costs
• The
applica9on
is
totally
aligned
with
the
business
core
To
reduce
the
risk
and
cost
of
star9ng
from
scratch
• New
market
genera9on
• Improved
customer
reten9on
• BeGer
applica9on
performance
• Increasing
revenue
growth
To
create
future
value
through

6. Added Value of ARTIST
Business
• It
includes
a
feasibility
analysis
before
any
investment
is
actually
made
• It
includes
business
model
issues
that
are
strongly
linked
to
the
technical
decisions
that
are
made
• It
takes
into
account
the
impact
of
the
business
model
shiC
in
the
organiza9on
processes
Technology
• It
is
focused
on
Cloud-­‐compliant
architectural
issues
at
both
applica9on
and
infrastructure
levels
• It
fosters
reusability
and
automa0on
• It
globally
prepares
the
soMware
for
its
evolu0on
