Der er ikke to skyer, der er ens. P\u00e5 cloud computing<\/a> der findes forskellige modeller. Offentlige skyer, private skyer, hybride skyer og community clouds er forskellige alt efter, hvem tjenesterne kommer fra, hvordan de er organiseret, og hvilken m\u00e5lgruppe de er rettet mod. <\/p>\n

En for alle: Public Cloud <\/h2>\n

En offentlig cloud, ogs\u00e5 kaldet en offentlig cloud, er frit tilg\u00e6ngelig og \u00e5benlyst tilg\u00e6ngelig for en stor offentlighed af en udbyder via netv\u00e6rket. De respektive udbydere, her prim\u00e6rt kendt som udbydere som Amazon, Google eller Microsoft<\/a>levere infrastrukturen i deres cloud. Adgang for brugere via internettet sker normalt uden s\u00e6rlige begr\u00e6nsninger. I tilf\u00e6lde af en offentlig cloud har brugeren hverken indsigt i eller kontrol over, hvor eller hvordan udbyderen opererer. Det er ogs\u00e5 vigtigt at vide, at alle brugere af en offentlig cloud har adgang til den samme infrastrukturpulje. Konfigurationen samt den garanterede sikkerhed og de varianter, der er tilg\u00e6ngelige for brugeren i skyen, er begr\u00e6nset til det v\u00e6sentlige. <\/p>\n

Til geng\u00e6ld f\u00e5r brugerne af en offentlig cloud gavn af massevirksomhed. Det skyldes, at den p\u00e5g\u00e6ldende udbyder overv\u00e6lter sine finansielle udgifter til infrastrukturen p\u00e5 et stort antal brugere. Hver enkelt betaler de lave omkostninger p\u00e5 et pay-as-you-go grundlag. P\u00e5 grund af deres n\u00e6sten ubegr\u00e6nsede antal servere er offentlige skyer ogs\u00e5 ekstremt p\u00e5lidelige. Hvis en komponent svigter, kan den p\u00e5g\u00e6ldende sky f\u00e5 adgang til andre komponenter inden for meget kort tid.<\/p>\n

Det lukkede samfund: private skyer <\/h2>\n

Private clouds er tjenester, der drives og organiseres af virksomheder eller organisationer selv. Ofte foretr\u00e6kker virksomheder, myndigheder eller institutioner disse private clouds af databeskyttelseshensyn eller af hensyn til sikkerheden i deres IT, som de kun giver adgang til til deres egne medarbejdere. Autoriserede brugere kan ogs\u00e5 v\u00e6re kunder, forretningspartnere eller leverand\u00f8rer. Design og hosting af private clouds kan udf\u00f8res internt. I dette tilf\u00e6lde er IT'en placeret inden for egen organisation og kan tilg\u00e5s via det interne netv\u00e6rk, intranettet. Ekstern hosting er ogs\u00e5 mulig. Eksternt hostede skyer, dvs. hostet af en specialiseret tredjepart, er lige s\u00e5 eksklusive som interne private skyer og tilbyder s\u00e5ledes den sikkerhed, som offentlige skyer mangler. P\u00e5 den anden side er omkostningerne ved private clouds h\u00f8jere. Udbydere af ekstern hosting er specialiserede virksomheder og i stigende grad ogs\u00e5 teleselskaber.<\/p>\n

Blandingen: hybride skyer<\/h2>\n

Hvis offentlige og private skyer kombineres, taler vi om hybride skyer. I denne hybridform kan visse tjenester p\u00e5 den ene side k\u00f8re p\u00e5 internettet med offentlige udbydere, mens andre applikationer af hensyn til databeskyttelsen forbliver i virksomheden. Udfordringen her er at opdele forretningsprocesser i kritiske og ikke-kritiske processer med hensyn til databeskyttelse. Ud over den fleksible brug af alle ressourcer er fordelene ved hybrid cloud'en den gode skalerbarhed og de lavere omkostninger sammenlignet med den rene private cloud. Forvaltningen af skyen er dog forbundet med en st\u00f8rre indsats. Der er ogs\u00e5 en risiko for, at Data<\/a> at komme ind i den forkerte sky er h\u00f8jere. Desuden er administrationsarbejdet st\u00f8rre med hybrid cloud.<\/p>\n

God til projekter: F\u00e6llesskabets sky<\/h2>\n

F\u00e6llesskabsskyer er et s\u00e6rtilf\u00e6lde. I dette koncept forbinder organisationer eller virksomheder i en branche hinanden via deres private clouds for at danne en cloud. Alle medlemmer af f\u00e6llesskabet har adgang til denne f\u00e6llesskabssky. N\u00e5r organisationer eller virksomheder har lignende eller identiske opgaver, som de \u00f8nsker at bruge en f\u00e6lles infrastruktur til, er disse skyer ideelle. Brugerne er forbundet af de samme krav, f.eks. overholdelse af s\u00e6rlige sikkerhedsspecifikationer eller lovbestemmelser, f.eks. med hensyn til datasikkerhed og databeskyttelse. Community clouds er ofte ikke begr\u00e6nset til at levere infrastruktur og tjenester, men er ofte t\u00e6t forbundet med brugernes forretningsprocesser.<\/p>","protected":false},"excerpt":{"rendered":"
