De ce anatomia ?

De ce nor ? •  Metafora •  Simboliza retelele telefonice, apoi Internetul •  AbstracIzarea infrastructurii din care e format Internetul

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.

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

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

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)

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.

Piramida abordărilor, nivelelor Difera in funcIe de natura informaIei prezentate beneficiarului.

•  SaaS

•  PaaS

•  IaaS

IaaS = Infrastr as a Service • Ofera processing, storage, network

• Beneficiarul poate sa instaleze si ruleze soaware inclusiv sisteme de operare si aplicaIi

IaaS vendors •  Amazon – EC2 •  Rackspace Cloud (Mosso) •  GoGrid •  …

•  Si mulI mulI alI provideri de servicii IaaS

Typical IaaS con5igurator

Infrastructure Anatomy •  Hypervisor – Xen, Hyper-‐V, Vmware •  Storage – iSCSI, fiberchannel, Infiniband •  Network •  Control panel •  AccounIng, billing

Interfata tipica

•  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.”

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

PaaS vendors •  Google App Engine •  Microsoa Azure •  Salesforce Force.com plaeorm

SaaS = Software as a Service

•  Salesforce, Netsuite – CRM; •  Basecamp – PM; •  Gmail, Hotmail – mail ; •  Google Docs – office; •  Facebook – social; •  Evernote – remember anything; •  Flicker – image storage

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

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

No panacea ! •  Nu este rezolvarea tuturor problemelor •  Posibile neajunsuri

Securitate •  IdenIty management •  Access control •  AuthorizaIon and authenIcaIon

www.cloudsecurityalliance.org

Livrarea datelor prin retea •  Bandwidth bomle neck •  Data centers downIme •  Providers downIme

Continuitatea business-‐ului •  Fail-‐over ( amazon EBS storage probleme ! )

Apartenenta si migratia datelor

•  Rezilierea contractului – cum obInem datele inapoi? In ce format? UIlizabil ?

•  Apartenenta datelor – cui aparIn datele odata ajunse in Cloud?
