?
• Metafora
• Simboliza
retelele
telefonice,
apoi
Internetul
• AbstracIzarea
infrastructurii
din
care
e
format
Internetul

7. De5initii
• Defini&a
mea:
Prezentarea
si
livrarea
resurselor
computaIonale
scaalbile
sau
a
aplicaIilor
prin
intermediul
unei
retele.
• Na&onal
Ins&tute
of
Standards
and
Technology
(NIST,
2011)
:
Cloud
compuIng
is
a
model
for
enabling
ubiquitous,
convenient,
on-­‐demand
network
access
to
a
shared
pool
of
configurable
compuIng
resources
(e.g.,
networks,
servers,
storage,
applicaIons,
and
services)
that
can
be
rapidly
provisioned
and
released
with
minimal
management
effort
or
service
provider
interacIon.

8. Istoric
• Amazon
–
majoritatea
vanzarilor
in
Decembrie.
• Resursele
computaIonale
nesolicitate
Imp
de
11
luni
ramase
• Ineficienta
–
costuri
inalte
(management
DC
–
racire,
curent,
spaIu,
etc).
• Amazon
decide
in
2002
sa
transforme
problema
in
oportunitate
si
lanseaza
Amazon
Web
Services.
• Costurile
dezvoltarii,
gazduirii,
menInerii
aplicaIilor
a
devenit
foarte
ridicat
si
organizaIile
s-­‐au
imparIt
in
provideri
si
beneficiari

9. Predictii
• In
Ianuarie
2010,
Gartner
prezice
“By
2012,
20
percent
of
businesses
will
own
no
IT
assets”.

10. Caracteristici
Cloud
computing
• On-­‐demand
(acces
la
cerere
)
• Broad
network
access
• Resource
pooling
(mulI-­‐tenancy)
• Rapid
elasIcity
• Measured
Service
(control,
monitor,
report)
• Off-­‐premise
(service
hosted
and
delivered
from
a
locaIon
that
belongs
to
a
service
provider)

11. Modele
de
livrare
• Public
–
hosted
off-­‐premise,
internet
based
delivery,
mulI-­‐
tenant.
• Private
–hosted
on-­‐premise,
connected
to
the
using
org
thru
private
network
links.
Data
owner
(
or
a
trusted
partner
)
control
the
service
management.
• Hybrid
–
mix.
Ex.
a
provider
supply
private
cloud
to
customer
over
VPN.
Other
ex
–
keep
web
interface
(
online
environment
)
in
public
cloud
but
data
processing
in
private
cloud.

12. Piramida
abordărilor,
nivelelor
Difera
in
funcIe
de
natura
informaIei
prezentate
beneficiarului.
• SaaS
• PaaS
• IaaS

13. IaaS
=
Infrastr
as
a
Service
• Ofera
processing,
storage,
network
• Beneficiarul
poate
sa
instaleze
si
ruleze
soaware
inclusiv
sisteme
de
operare
si
aplicaIi

14. IaaS

• Network
• Control

17. Interfata
tipica

18. • NIST
(
NaIonal
InsItute
of
Standards
and
Technology
)
“Plaeorm
as
a
Service
is
the
ability
to
provide
a
compuIng
environment
and
the
related
development
and
deployment
stack
needed
to
deliver
a
soluIon
to
the
consuming
customer.”

19. Caracteristici
PaaS
• PaaS
–
limbaj
de
programare
privat
• Suporta
intregul
ciclu
de
soaware
development,
de
la
testare
pana
la
release
in
producIe
• Să
implementeze,
să
gesIoneze,
sa
testeze
şi
să
ruleze
aplicaţiile
create
• Include
si
suporta
interfete
precum
SOAP,
REST,
XML

22. Caracteristici
SaaS
• Acces
la
cerere
• Configurare
si
nu
modificare
(
customizare
)
• Accelerated
feature
delivery
• SOA
(service
oriented
architecture)
• Sisteme
incorporate
pentru
generarea
reporturilor
• Important
-­‐
datele
clienIlor
sa
fie
pastrate
separat,
intr-­‐un
mediu
strict
securizat

23. Economia
cloud-­‐ului
Costul
unei
aplicaIi
(TCO)
este
alcatuit
din
:
• Server
• Storage
• Network
• Backup
&
archive
• Data
center
infrastructure
• Plaeorm
• Soaware
maintenance
• Help
desk
support
• OperaIon
support
personnel

24. No

• Nu

rezolvarea
tuturor
problemelor
• Posibile
neajunsuri

25. Securitate
• IdenIty

26. Livrarea
datelor

27. Continuitatea
business-­‐ului
• Fail-­‐over
(

!
)

28. Apartenenta
si
migratia
datelor
• Rezilierea
contractului
–
cum
obInem
datele
inapoi?
In
ce
format?
UIlizabil
?
• Apartenenta
datelor
–
cui
aparIn
datele
odata
ajunse
in
Cloud?
