12. What
is
Cloud?

13. “That’s
where
rain
comes
from”
Andrei
Zmievski

14. Cloud
=
Internet

15. DefiniXon
A
model
for
consumpXon
&
delivery
on
the
internet
where
flexibility
is
essenXal
&
can
be
guaranteed
through
abstracXon

16. Internet
as
a
uXlity

17. Translated
to
what
we
know
&
need

18. Always
available

19. Fast
(enough)

20. Scalability
Up
&
down
vs
out
&
in

21. Focus
on
using,
do
what
you’re
good
at

22. Leave
the
rest
to
others

24. Higher
up
the
stack

25. Economic
advantages

26. Less
money
Less
effort
Less
risk
Less
worries

27. Hybrid
let’s
you
do
that

28. Hybrid
is
just
a
fancy
way
of
saying

29. Pick
the
pieces
of
the
puzzle
yourself

34. Combell
Fully

soluXons

35. Easy
peasy,
right?

37. Single
point
of
failure

38. Shared
nothing

39. Nothing
is
local

40. Distributed
systems

41. Easy
to
deploy
&
manage?

42. How
do
you
deal
with
$_SESSIONS?

43. ReplicaXon
