Anatomy of a Cloud
The document provides an overview of cloud computing anatomy by defining key terms, describing the history and characteristics of cloud computing models, and explaining the different cloud service models of IaaS, PaaS, and SaaS. It defines cloud computing, discusses Amazon's role in its development, and outlines the main features of infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS).

- 6. De ce nor ? • 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 vendors • Amazon – EC2 • Rackspace Cloud (Mosso) • GoGrid • … • Si mulI mulI alI provideri de servicii IaaS

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

- 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
- 20. PaaS vendors • Google App Engine • Microsoa Azure • Salesforce Force.com plaeorm
- 21. SaaS = Software as a Service • Salesforce, Netsuite – CRM; • Basecamp – PM; • Gmail, Hotmail – mail ; • Google Docs – office; • Facebook – social; • Evernote – remember anything; • Flicker – image storage
- 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 panacea ! • Nu este rezolvarea tuturor problemelor • Posibile neajunsuri
- 25. Securitate • IdenIty management • Access control • AuthorizaIon and authenIcaIon www.cloudsecurityalliance.org
- 26. Livrarea datelor prin retea • Bandwidth bomle neck • Data centers downIme • Providers downIme
- 27. Continuitatea business-‐ului • Fail-‐over ( amazon EBS storage probleme ! )
- 28. Apartenenta si migratia datelor • Rezilierea contractului – cum obInem datele inapoi? In ce format? UIlizabil ? • Apartenenta datelor – cui aparIn datele odata ajunse in Cloud?
