Alveycomputing

Id wekwos alveycomputing gwehmt ex Englisch cloud computing, ab informatique professionals qui niemskweer ia nov informatic systemes wehrgend med id joint action om roibh elements samghat sonter ir geographic localization ed id subkeihnd infrastructure. Tod nam est assocyen ei nebhskeip symbol (cloud) quod kyeust yando Internet in ia schemas iom informatic netwehrgs. 
==Quod est alveycomputing==
Alveycomputing consist nudes distant informatic servers med uno netwehrg, daydey Internet, kay stocke data we exploite ia. 
Ia distant servers bihnti stajern ep demande, opsst-ye per neudrewos, sekwent technic criteria (stieure, bandewure, etc...), bet kathalika ratib-ye. Alveycomputing kweit med sieno megil uriende : sekwent id competence nivell al clientneuder, est possible manage per se sien server we se contente med nudes distant applications. 
Alveycomputing yinjier consist tyices ia beorbatens neti ep ia inner servers ios entreprise, sontern ep outsourcet servers managet ab national au international dadwers kam Google, Amazon au Microsoft. Ta mega-servers sonti dayna tienxia, aun od est woiden in quod wehst un datum ye instant-on. Bihti tunkye meg difficil swekwehre id respect ios export ban iom personal daten, ploisko sei id dadwer ghehdt garantie id localisation sienen servern. 
Idpet notion os localisation uns datios leusti sem ex sien sense, inghi id alvey un datum ghehdt ses fractiont ed idsa schtuks dayt inter plur lands. Id datum ka solg neti est tunkye semloc, quo eiskwt id werd ios bestehmen ios applicable ieus.

==Historia os alveycomputing==
Ia dasturs subkeihnd id alveycomputing tarikhe tsay do ia 1950tias (diu pre gnahsit id wekwos "alveycomputing/cloud computing"). Ye tod zaman, i neuders access pon ir terminals sem applications wehrgend med, central quaders (mainframes) qua correspons ia atavs iom servern os alveycomputing. I netwehrgarchitectes (qui concepe ia intra- ed interentreprise netwehrgs) kip Internet do uno nebh. In Englisch eet tun tolcto de the cloud, quo mieyn edvas Internet. 
"Alveycomputing" buit popularisen ab Amazon.com enmercatend sien Elastic Compute Cloud product in 2006, references ei phrase cloud computing prohp tem aus quem 1996, samt id prest gnoht mention in un Compaq interne document. 
Id symbol "nebh" (cloud) buit nuden kay kipes netwehrgs om computing schowbeys in id original ARPANET tem aus quem 1977, ed ab id CSNET circum 1981 - bo predecessors eiswo Internet. Id werd "nebh" buit nuden ka metaphor pro Internet ed un standardisen nebhlik forme buit uset kay denote uno netwehrg in telephonia schematique. Samt tod simplification, id implication est od ia sonterkweitus de kam ia endpoints unios netwehrg sont connex ne sont relevant pro ia ziels os ghabe id digramme. 
Id lexis "nebh/cloud" buit nuden kay se refere ibs platformes os nohmt computing tem aus quem 1993, kun id "Apple spin-off" General Magic ed AT&T med id describend-ye ir (couplen) Telescript ed PersonalLink technologias.
In-kap ia 2000ents apparihr Web hosta qua ghehde herbehrge applications in ir informatic locals. In tod context, id atav ios Software ka Service correspons id application service dadwer. Ia prest Web 2.0 applications qua buir wohngen do alveycomputing sont id blixbrev, id software test. 
Id promotion os alveycomputing buit possiblihn ab id generalisation iom Internetaccessen im privat individus ed iom entreprisen. Id phenomen brug idschi muhim augen iom informatic schowbeys qua hant permiss ibs hostims propones stets interessanter tariffs. In tod sense, id mode os alveycomputing profitet id muhim augos iom servern (id functionmentsfrequence iom servern buit multiplien decs inter 1998 ed 2008, ia processors comprindent inter quar ed dec kerds); ed id sehnken iom stockencosten (po id pris uns darmdisk os 1,2 Go in 2000, hams, in 2013, un disk om 1000 Go)
In alveycomputing, ia entreprises neti folossient ir informatic servers, sontern accede sem in-ligne services uns infrastructure managet ab id dadwer. Ia applications ed data ne wehse ep id local computer, sontern ep un "alvey" composen ex distant interconnexa servers. Dat id complexitat iom netwehrgdiemens ed ios multiplicitat iom interveners (Internet access dadwers, host, editor, repehrner), id functionment in alvey meinct id mussalsalia ed id qualitat ios service binisbat un application os professional qualitat herbohrgen eni id entreprise. Tod concept est presentet ka uno major evolution ab semens meg gnoht analystens, kam Gartner Group, ed ka uno mode correspondend commercial motivations, ab alyens specialistens. Maght bihe ayt od id alveycomputing, assocyen uni behandenkweitu iom accessen ei Internetwehrg in interconnecten weurbande ed megweurbande, hat emergiht un hol opossector, entitats qua, transvers-ye, offerte webservices pro id pledveh sub forms om webapplications au, meis specific-ye, pro id professional sector, naudhend un service-orientet proschgumt ed productive moinis (exterpapiereihsa, mathmounenmanagement), architecture ep meid.

==Service models==
Quayque service-orienten architecture advoquet "Quant ka Service" (Englisch acronym "QaS"), alveycomputing dadwers offerte ir "services" sekwent different models, ex-ya ia tri standard models per id National Institute Standards and Technology sont "Infrastructure ka Service" (IkS), Platforme ka Service (PkS) ed Sotware ka Service (SkS). Ta models anancent crehscend abstraction; itak bihnt ops-ye portrait ka lyehgers in un kowp : infrastructure-, platforme-, ed software-ka-service, bet ta ne naudhe bihe yuct. Mathalan, anghen ghehdti dadwe SkS enovern ep physic machines (bare metall), aun nudes subkeihnd PkS ni IkS lyeghers, ed witerom anghen ghehdt wehrgihes un programme ep IkS ed accede id direct-ye, aun vulbhes id ka SkS.
==Inconvenients os alveycomputing==
Plur categorias inconvenienten existe :
- id neud iom public netwehrgs, in id fall os public alvey, dreibht riska bohndt ei securitat ios alvey. Idghi connexion inter ia computerstations ed ia applicative servers leit per id Internetwehrg ed expont ad idafi riska om cyberattaques ed jincienia klehpts. Tod risk exist pro privat individus, betschi pro meger ed media entreprises, qua hant diutos protect ir servers ed applications ud extos attaques, dank inner enderdilen netwehrgs; 
- el client uns alveycomputingservice biht meg dependent id qualitat ios netwehrgios kay accedde tod service. Neid dadwer os alveyservice ghehdt garantie 100% behandetstand. Mathalan, kussours ep ia alveyservices bihnt referencen ab id Internet Working Group of Cloud Resiliency
- ia entreprises leuse id waldh upper id implantation iren daten. Ex tod fact, ia interapplicative interfaces (qua maghe ses volumineus) bihnti maung-ye complexer ad enover quem ep un innerherbohrct architecture; 
- ia entreprises neti hant garanties (alya quem contractual) de id neud kwohrt ex ir data, chunke betreusent ia ad terts;
- dikswerds bihnt iskwn ab id absence os precis localisation iom daten os alveycomputing. Ia loys in gwis ghehlde bet pro quod server, quod datencentre ed, bilhassa, quod land ?
- kam ia local-ye installet softwares, permitte ia alveycomputing services lance attaques (anyowdwinegh, denegen service...). In 2009 mathalan, un Troia ekwo hat nudt illegal-ye un service ios public alvey os Amazon kay infece computers.
==Digital forensique in id "alvey"==
Id probleme os duce soks quer ia alveyskladapparats khake bihe physic-ye access hat gohnt uno numer changen ad quosmed digital pruvs bihnt localiset ed collect. 
In sem scenarios ia existend digital forensique alats ghehde bihe employen kay accede id alveysklad kam netwehrgtolkers (quayque to est un lent processo gehnend un large mikdar os Netwehrgtrafic). 
Un alternative proschgumt est wehnge un alat quod act eni idswo alvey. 
Pro organisations neudend Office 365 med un "ES" subscription est id option os nudes Microsofts embaudhen e-aunstehgen ressurces, quayque ta ne dadwnt id hol functionalitat quod est typic-ye naudht pro un forensic process.
