Vi hører alle ordet Cloud nu og da, men jeg er sikker på, at mange af os ikke er helt sikre på Cloud og Cloud Computing . Så først og fremmest er det vigtigt at forstå, hvad skyen er.

Hvad er Cloud?

Cloud er bare en metafor for internettet, når vi siger cloud, vi refererer kun til internettet og blot de tjenester, vi bruger ved at bruge internettet – gennem vores webbrowsere. Når jeg nu siger Cloud Computing , så er der ingen standard branchedefinition, der taler om cloud computing, givet det faktum, at dette er i et begyndende stadium, og den eneste håndfuld virksomheder investerer i cloud computing & virtualisering, som ofte nævnes som FUTURE TENDENSER^{(FUTURE TRENDS)} .

Hvad er Cloud Computing?

Men med enkle ord ,"

Cloud Computing is more than the few internet-based services which we access through our web browsers, it is the fundamental shift from the traditional client/server or n-tier architecture, and it primarily focuses on the effective utilization of the IT INFRASTRUCTURE “.

De fleste udbydere af cloud^{(Cloud Service)} -tjenester tilbyder denne service på " pay as you go " -modellen. Med "pay as you go"-modellen betyder det, at du kun betaler for de tjenester, du bruger, og en række af de ressourcer, du bruger. Du faktureres kun for de tjenester og ressourcer, som du har brugt. Kort sagt, alt, hvad der tilbydes, er faktisk en service, som du bruger.

Du må tro, at det bare er endnu en beregningsmodel, så hvorfor skulle man have en interesse i det? Nå^(Well) , her er svaret på det! Lad mig orientere dig om funktionerne i den, og jeg er sikker på, at du vil være enig i, at det er en næste generations model.

Funktionerne er som følger:

• Skalerbare:^(Scalable:) Dette er meget skalerbare tjenester end de traditionelle tjenester, der har tendens til at nå en grænse på et vist niveau, men disse er designet og administreret til at imødekomme behovene hos mennesker rundt om i verden, fordi disse tjenester replikeres i de datacentre, som har en meget god geo-fordeling.
• Automatiseret servicestyring^{(Automated Services Management)} : Nå, det betyder ganske enkelt, at du ikke behøver at bekymre dig om arbejdskraft, servere, softwareopgraderinger, hardware osv. alt sammen administreres af cloud-servicevirksomheden. Jeg vil uddybe dette i et fremtidigt indlæg om Windows Azure .
• Høj tilgængelighed:^{(High Availability: )} Disse har næsten 99,9999 % oppetidstjenester, fordi de har tusindvis af datacentre over hele kloden, og de har hundredvis af forekomster, som er replikeret på dem, så selvom en server fejler, springer andre ind for at betjene klienten.
• Multi-tenancy : One Cloud – mange lejere, det er den måde de fleste Cloud -tjenesteudbydere effektivt udnytter den underliggende IT-infrastruktur. De har mange kunder, hvis tjenester kører på et enkelt datacenter.
• Virtualisering^{(Virtualization)} : Det er faktisk det vigtigste aspekt af det. Cloud -tjenesteudbydere har datacentre, hvor de kører tusindvis af servere virtuelt ved hjælp af en hypervisor, hvilket øger den effektive udnyttelse af ressourcerne på blot 40-45 % til omkring 85 %.

Så hvad det faktisk gør, er, at det tager al stresset med at administrere dine servere, databaser, sikkerhedsrettelser, softwareopgraderinger, infrastruktur osv. (i tilfælde af public cloud) fra dig.

Nogle almindelige myter om at flytte virksomheder til Cloud Service

For at små og mellemstore virksomheder skal have succes, er det vigtigt at inkorporere visse egenskaber såsom forretningsadfærdighed, fleksibilitet og evnen til at spare ekstra omkostninger. Alt dette og andre kan komme ved at flytte til Cloud Technology , men den forvirrende mængde af modstridende information, der flyder rundt på internettet^(Internet) , forhindrer os i at tage det rigtige skridt. At kende kendsgerningerne kan helt sikkert hjælpe med at aflive skymyter og fjerne forkerte forestillinger, som vi måske tror er sande.

Cloud computing myter

Den første myte^{(The first myth)} . Hvis vores data flyttes til skyen, vil vores virksomhed ikke længere have kontrol over vores teknologi. Her er hvad du behøver at vide! Når du flytter til skyen, reduceres tiden brugt på vedligeholdelse af hardware og opgradering af software betydeligt. Hvordan? Det kapitalbudget, der bruges på at vedligeholde servere på stedet til e-mail-opbevaring og arbejdsbelastninger, er stærkt reduceret. Så i stedet for at bruge store dele af ressourcer på servere, kan du tænke strategisk for at understøtte dine forretningsbehov på en mere forsigtig måde. Dette vil hjælpe dig med at bruge mere tid og energi på at forbedre forretningsdriften og iværksætte agile initiativer.

Den anden myte^{(The second myth)} . Det er mere sikkert at opbevare data på stedet end i skyen. Rigtigt? Bestemt ikke! Dine lokale systemer er ikke i sagens natur mere sikre, end de ville være i skyen. Sikkerhedseksperter siger, at der er en stigende tendens til problemer med cybertyveri. Mange virksomheder bliver rutinemæssigt hacket, så sikkerhed er vokset til et fuldtidsjob, da det kræver et team af eksperter for at forhindre sikkerhedsbrud. Heldigvis ansætter nogle af de virksomheder, der tilbyder cloud-tjenester som Microsoft , de bedste og dygtigste i denne branche. Dets team bruger processer såsom sikkerhedsudviklingslivscyklussen^{(Security Development Lifecycle)} ; trafik drosling; og forebygge, opdage og afbøde brud, som mange virksomheder ikke har ressourcerne til at sikre.

Ud over dette har Office 365 også en 99,9 procent økonomisk støttet oppetidsgaranti og holder sig ajour med de seneste regler og regler: HIPAA og Sarbanes-Oxley , Federal Information Security Management Act ( FISMA ), ISO 27001 , European Union (EU ) ) Modelklausuler^{(Model Clauses)} , USA-EU Safe Harbor-^{(U.S.–EU Safe Harbor)} ramme, Family Educational Rights and Privacy Act ( FERPA ) og den canadiske lov om beskyttelse af personlige oplysninger^{(Canadian Personal Information Protection)} og elektroniske dokumenter^{(Electronic Documents Act)} ( PIPEDA )), for at nævne et par stykker.

Den tredje myte^{(The third myth)} . Du skal flytte alt til skyen. Kort sagt er det et alt-eller-intet-scenarie. Ikke sandt! Cloud giver dig fuld kontrol over at levere den computerkraft og de muligheder, som din virksomhed nødvendigvis kræver.

Den fjerde myte^{(The fourth myth)} . Cloud koster arbejdspladser. Ikke sandt! I stedet for at tage job, har Cloud computing skabt job.

Endelig^(Lastly) tror mange, at regeringer får adgang til alle data, hvis de er i skyen. Dette er en stor frygt, som mange virksomheder har omkring skyen og forhindrer dem dermed i at adoptere denne teknologi. Det er ubegrundet! Hvorfor? Det er kun leverandørens it-team, der administrerer adgang, opsætter rettigheder og begrænsninger og giver smartphoneadgang og muligheder. Virksomheden forbliver eneejer og bevarer alle rettigheder, ejendomsret og interesser i de data, der er gemt i skyen. Desuden bruges dataene ikke til nogen form for annoncering eller til andre formål end at give dig tjenester, som du har betalt for.

What is Cloud and Cloud Computing? An introduction for beginners!

We all hear thе word Cloud now and then but I, am sure many of us aren’t exactly very sure about Cloud and Cloud Computing. So first of all, it is important to understand,  what is the cloud.

What is Cloud?

Cloud is just a metaphor for the internet when we say cloud, we are just referring to the internet only and simply the services we use using the internet – through our web browsers. Now when I say Cloud Computing, then there is no standard industry definition which talks about cloud computing, given the fact that this is in a nascent stage and the only handful of companies are investing in cloud computing & virtualization which are often cited as the FUTURE TRENDS.

What is Cloud Computing?

But, in simple words,”

Cloud Computing is more than the few internet-based services which we access through our web browsers, it is the fundamental shift from the traditional client/server or n-tier architecture, and it primarily focuses on the effective utilization of the IT INFRASTRUCTURE “.

Most Cloud Service providers offer this service on the “pay as you go” model. By “pay as you go” model it means that you pay only for the services you use and a number of the resources you use. You are billed for only those services & resources that you consumed. In short, everything that is offered is actually a service that you use.

You must be thinking it’s just another computational model, so why should one have an interest in it? Well here is the answer to it! Let me brief you with the features of it, and I am sure you will agree that it is a next-generation model.

Features are as follows:

• Scalable: These are highly scalable services than the traditional services that tend to reach a limit at a certain level, but these are designed and managed to cater to the needs of people around the world because these services are replicated at the data centers which have a very good geo-distribution.
• Automated Services Management: Well, it simply means you don’t have to worry about the manpower, servers, software upgrades, hardware, etc. all are managed by the cloud services offering company. I will elaborate this in a future post on Windows Azure.
• High Availability: These have almost 99.9999% uptime services because they have thousands of data centers across the globe and they have hundreds of instances which are replicated on them, so even if one server fails other jumps in to serve the client.
• Multi-tenancy: One Cloud – many tenants, that is the way most Cloud service providers, effectively utilize underlying IT infrastructure. They have many clients whose services are running on a single data center.
• Virtualization: It actually is the most important aspect of it. Cloud service providers have data centers where they run thousands of servers virtually using a hypervisor which increases the effective utilization of the resources of a mere 40-45% to around 85%.

So what it actually does, is that it takes all the stress of managing your servers, databases, security patches, software upgrades, infrastructure, etc. ( in the case of public cloud) from you.

Some common Myths about moving Businesses to Cloud Service

For any small and medium-sized businesses to be successful, it is essential to incorporate certain traits like business agility, flexibility,  and the ability to save extra costs. All this, and others can come by moving to Cloud Technology but the bewildering amount of contradictory information floating around on the Internet stop us from making the right move. Knowing the facts can certainly help to bust cloud myths and dispel wrong notions that we might think are true.

Cloud computing myths

The first myth. If our data moves to the cloud, our business will no longer have control over our technology. Here’s what you need to know! When you move to the cloud, time spent in maintaining hardware and upgrading software is significantly reduced. How? The capital budget spent on maintaining servers on-premises for email storage and workloads is greatly reduced. So, rather than spending large portions of resources on servers, you can think strategically to support your business needs in a more prudent manner. This will help you spend more time and energy in improving business operations and launching agile initiatives.

The second myth. Keeping data on-premises is safer than in the cloud. True? Certainly not! Your on-premises systems aren’t inherently more secure than they’d be in the cloud. Security experts say there’s a rising trend seen in cyber theft problem. Many companies are routinely hacked so security has grown into a full-time job as it requires a team of experts to thwart security breaches. Fortunately, some of the companies offering cloud services like Microsoft hires the best and brightest in this business. Its team uses processes such as the Security Development Lifecycle; traffic throttling; and preventing, detecting, and mitigating breaches that many companies don’t have the resources to ensure.

Apart from this, Office 365 also has a 99.9 percent financially backed uptime guarantee and keeps itself up to date with the latest regulations and rules: HIPAA and Sarbanes-Oxley, Federal Information Security Management Act (FISMA), ISO 27001, European Union (EU) Model Clauses, U.S.–EU Safe Harbor framework, Family Educational Rights and Privacy Act (FERPA), and the Canadian Personal Information Protection and Electronic Documents Act (PIPEDA), to name a few.

The third myth. You have to move everything to the cloud. In short, it is an all-or-nothing scenario. Not true! Cloud gives you complete control for delivering the computing power and capabilities that your business necessarily demands.

The fourth myth. Cloud costs jobs. Not true! Instead of taking jobs, Cloud computing has created jobs.

Lastly, many believe governments get access to all the data if it is in the cloud. This is a major fear many businesses have about the cloud and thus stops them from adopting this technology. It’s unfounded! Why? It is just the vendor IT team that manages access, sets up rights and restrictions, and provides smartphone access and options. The company remains the sole owner and retains all the rights, title, and interest in the data stored in the cloud. Moreover, the data is not used for any sort of advertising or for any purpose other than providing you services that you have paid for.
