Xisaabinta Cloud^(Cloud) waa mid ka mid ah isbeddellada tignoolajiyada ugu kulul maalmahan. Laga soo bilaabo xalalka kaydinta fudud si loo dhamaystiro codsiyada ganacsiga, xisaabin badan ayaa u guuraya daruuraha.

Laakin maadaama xogtayada ay sii kordheyso lagu hayo server-yada fog-fog ee adduunka oo dhan, su'aal waa in la is weydiiyaa: xisaabinta daruurtu runtii ma badbaadsan tahay?

Sidee sax ahaan xogtaada loogu hayaa codsiyada daruuraha? Ma heli karaan kuwa kale? Waa maxay khataraha amniga ee xisaabinta daruuraha? Halkan waxaa ah dulmar guud.

Cloud Computing 101

Caadiyan, kombayutarkaagu waxa uu qaban karaa oo kaliya sida qalabkiisu u ogolaado. Haddii aad rabto kaydin badan ama awood farsamayneed, waa inaad cusboonaysiisaa PC-gaaga. Laakiin iyadoo hoos u dhaca qiimaha isku xirka internetka uu yimid doorasho kale - daruuraha.

Dhismaha aasaasiga ah ee xisaabinta daruuraha^{(basic premise of cloud computing)} waa wax fudud. Halkii aad ka samayn lahayd barnaamijyo adag oo aad ku kaydin lahayd faylasha mashiinkaaga, waxaad ku socodsiinaysaa server fog. Server-kan fog waxa loo yaqaan daruuraha waxana uu masuul ka yahay in uu ku siiyo agabka xisaabinta ee shabakada

Tusaalooyinka ugu cad ee tan waa adeegyada kaydinta daruuraha sida Google Drive ama Dropbox^{(Google Drive or Dropbox)} . Codsiyadan daruuriga ah waxay ku siinayaan kayd gaar ah oo aad isticmaali karto si aad u xafiddo faylashaada. Maadaama aanay kaydintani ka iman kombayutarkaga, faylashani waa badbaado xataa haddii kombayutarkaga gaarka ahi xumaado ama jabo.

Dabcan, taasi waa uun xoqista aasaaska. Adeegyada daruurtu^(Cloud) aad bay uga sii fog yihiin kaydinta fog, iyagoo bixinaya wax walba laga bilaabo martigelinta webka ilaa codsiyada gebi ahaanba fog. Adeegyada sida Microsoft Azure iyo Amazon AWS waxaa isticmaala ganacsiyada adduunka oo dhan si ay u socodsiiyaan dhammaan noocyada codsiyada xisaabinta.

Faa'iidooyinka Xisaabinta Cloud

Waxaa jira faa'iidooyin badan oo ku saabsan xisaabinta daruuraha vs codsiyada dhaqanka.

Faa'iidada aasaasiga ah waa shaqo-^(redundancy) ka-soo-saarid . Xogta lagu kaydiyo jir ahaan hal qalab oo gaar ah waa la tirtiri karaa sababtoo ah arrin kasta oo farsamo ah, kharashka saacadaha shaqada iyo macluumaadka muhiimka ah. Daruurtu, dhanka kale, waxay isticmaashaa adeegayaal badan oo ku faafay meelo kala duwan oo juquraafi ah taasoo ka dhigaysa wax aan macquul ahayn in xogtu ay lunto.

Faa'iidada labaad ee weyn waa miisaanka^{(scalability)} . Codsiyada ganacsiga, aad ayay u adag tahay in la helo ilo xisaabeedyo badan si loo maareeyo culayska dheeraadka ah ee habaynta dhaqameed. Waxay u baahan tahay samaynta maalgashi lagu sameeyo awood qalab badan oo aan la isticmaalin inta badan.

Marka la eego xisaabinta daruuraha, codsiyadu waxay codsan karaan ilo badan sida iyo marka loo baahdo, iyagoo bixinaya kaliya awoodda la isticmaalay. Tani waxay ka dhigaysa socodsiinta abka la miisaami karo mid aad u kharash badan, oo aan la xusin si fudud loo hirgelin karo.

Nuglaanta Xisaabinta Cloud^{(Cloud Computing)}

Waxaan horay u aragnay faa'iidooyinka badan ee xisaabinta daruuraha. Laga soo bilaabo gelitaanka ilaa dib-u-celinta, waxaa jira dhibco badan oo wanaagsan oo ku saabsan isticmaalka adeegga daruuraha. Isla mar ahaantaana, si kastaba ha ahaatee, waxaa jira dhowr cilladood sidoo kale.

Welwelka ugu weyn waa amniga xogta. Maadaama xogtaada lagu hayo server si guud loo heli karo, ammaankeedu kuma jiro gacmahaaga. Shirkadda maamusha adeegga daruuraha (iyo adeegayaasheeda) ayaa si buuxda u koontaroolaya macluumaadkaaga.

Marka la eego, way ka ammaan badan tahay kombuyuutarka gaarka ah. Hal cillad qalabeed ma halis gelin karto dhammaan xogtaada. Laakiin isla mar ahaantaana, waxay sidoo kale soo bandhigaysaa macluumaadka hanjabaadaha dibadda. Jabsiga wax u dhimaya adeegayaasha daruuraha ayaa daadin kara xogtaada shaqsiyeed.

Wax badan oo ku saabsan, waxaad u baahan tahay inaad ku kalsoonaato bixiyaha adeegga daruuriga laftiisa si uu u ixtiraamo sirtaada. Iyo da'dan ee Xogta Weyn^{(Big Data)} , taasi waa wax dhib ah oo la bixiyo. Kooxda Farsamada ayaa si joogta ah ula kulmay dhaleeceynta ku xad-gudbida xogta gaarka ah ee xogta isticmaalaha ee ay heli karaan, taas oo ka dhigaysa khatar in lagu kaydiyo macluumaadka muhiimka ah ee daruuraha.

Kadibna waxaa jira dayacanka amniga xitaa adeegyada daruuraha ayaa la soo bandhigay. Sida adeeg kasta oo shabakad ah, xisaabinta daruuraha waxay noqon kartaa mid lagu maareeyo Weerrada Qaybsan-Denial-of-Service^{(Distributed-Denial-of-Service)} ( DDoS ) ee curyaamiya awoodeeda. Tani waxay ku qasbaysaa adeega ay saamaysay inuu khad ka baxo, taasoo ka dhigaysa codsigaga mid aan la heli karin muddo aan la garanayn.

Yaraynta Khatarta

Hagaag^(Okay) , markaa xisaabinta daruuraha ayaa suurtagal ah inay nugul tahay. Haddaba, waa maxay xalku? Ma tahay inaad gebi ahaanba joojiso isticmaalka adeegyada daruuraha?

Dabcan maya. Dhammaan khataraha amniga aragtida ee ka dhex jira xisaabinta daruuraha, dhab ahaantii waa mid ka mid ah noocyada ugu ammaansan ee xisaabinta. Waad ku mahadsan tahay dib-u-celinta lagu dhejiyay server-yada daruuraha, waxaa jira dhibco aad u yar oo guuldarro ah.

Luminta xogta^(Data) ama xatooyada adeegga daruuriga waxay u baahan tahay masiibo, halkii ay ka ahaan lahayd koob shaaha ah oo daadanaya oo laga yaabo inay tilmaamaan ciribtirka macluumaadka ku kaydsan laptop-kaaga. Caadi ahaan sidoo kale way ku adag tahay tuugtu inay soo galaan, maadaama bixiyeyaasha adeegga daruurtu u muuqdaan inay isticmaalaan tallaabooyin ammaan oo ka wanaagsan PC-ga.

Kumbuyuutarrada shakhsi ahaaneed waxay sidoo kale ku dhici karaan weerarrada ransomware, kuwaas oo xira xogtaada shakhsi ahaaneed oo dalbanaya lacag bixinta cryptocurrencies si ay kuu oggolaadaan inaad gasho. Malware-yada kale waxay si toos ah u burburin karaan dhammaan faylasha, taas oo ka dhigaysa xisaabinta daruuraha xitaa lama huraan.

Si loo hagaajiyo ammaanka xogtaada, sir^(encryption) ayaa la isticmaali karaa. Kaydka xogta iyo adeegyada kaydinta daruuraha, sir xogta nidaamkaaga ka hor inta aanad soo dejin. Dhammaan codsiyada ka socda daruuraha, isku day adeegyada kuu oggolaanaya inaad sir xogta la^{(encrypt the information)} isticmaalay. Habkaas, xitaa jabsiga ama daadinta xogta wax khatar ah kuma laha xogtaada khaaska ah. 

Xisaabinta Cloud ma sugan tahay?

Weydiinta haddii xisaabinta daruuraha ay ammaan tahay waxay la mid tahay weydiinta haddii duullimaadyadu ay yihiin waddo ammaan ah oo lagu safro. Marka loo eego tirakoobka, waa qaabka ugu ammaansan ee jira, in kastoo, dabcan, ma jiraan wax khatar ah oo gebi ahaanba ka xor ah.

^(Cloud)Khatarta ugu weyn ee Cloud Computing ma keenaan hackers ama cillado farsamo, balse waxaa keena maamul xumo ula kac ah. Dabeecadda server-yada daruuraha ayaa aad ugu adkeyd inay jabsadayaasha soo galaan, waxayna dammaanad ka qaadayaan badbaadada ka hortagga burburka qalabka.

Waxa kaliya ee wax u dhimi kara xogta daruuraha waa adeeg bixiyaha laftiisa. Inkastoo shirkadaha farsamada sida Google ama Amazon ay isu dhiseen shirkado la aamini karo oo ku jira nichen, inaad dhammaan ukumahaaga ku dhejiyaan hal dambiil marna fikrad wanaagsan maaha.

Tallaabooyin fudud sida sir xogtaada iyo ku kalsoonaanta bixiyeyaasha adeegga daruuraha siyaasad sirnimo oo hufan ayaa kaa caawin karta ilaalinta faylashaada iyo macluumaadka kale ee gelitaanka aan loo baahnayn. Haddii aad indhahaaga furto, way fududahay in la yareeyo khataraha amniga ee xisaabinta daruuraha oo aad ku raaxaysato faa'iidooyinkeeda.

What Are the Security Risks of Cloud Computing?

Cloud сomрuting is one of the hottest technology trends these days. From simple storage solutions to complete enterprіse applications, a lot of cоmputing is moνing to the cloud.

But as our data is increasingly held in remote servers across the world, a question must be asked: is cloud computing really safe?

How exactly is your data held in cloud applications? Can it be accessed by others? What are the security risks of cloud computing? Here is a comprehensive overview.

Cloud Computing 101

Normally, your computer can only perform as well as its hardware lets it. If you want more storage or processing power, you have to upgrade your PC. But with the decreasing costs of internet connectivity came another option – the cloud.

The basic premise of cloud computing is quite simple. Instead of running complex programs and storing files on your machine, you run them on a remote server. This remote server is called the cloud and is responsible for providing you with computing resources through the network.

The most obvious examples of this are cloud storage services like Google Drive or Dropbox. These cloud applications give you a dedicated amount of storage that you can use to keep your own files. As this storage does not come from your PC, these files are safe even if your personal computer gets corrupted or breaks down.

Of course, that is just scratching the basics. Cloud services go much further than just remote storage, offering everything from web hosting to entirely remote applications. Services like Microsoft Azure and Amazon AWS are used by enterprises across the globe to run all kinds of computing applications.

The Advantages of Cloud Computing

There are many benefits of cloud computing vs traditional applications.

The primary advantage is redundancy. Data stored physically on a single personal device can be wiped out due to any technical issue, costing hours of work and important information. The cloud, on the other hand, uses multiple servers spread through various geographical locations making it virtually impossible for the data to just get lost.

The second big benefit is scalability. For enterprise applications, it can be very difficult to acquire more computing resources to handle extra load in traditional setups. It requires making an investment into more hardware capacity that would go unused most of the time.

With cloud computing, applications can request more resources as and when required, paying only for the capacity used. This makes running a scalable app very cost-efficient, not to mention easy to implement.

The Vulnerabilities of Cloud Computing

We have already seen the numerous advantages of cloud computing. From accessibility to redundancy, there are a lot of good points about using a cloud service. At the same time, however, there are a few drawbacks as well.

The principal concern is data security. As your data is held on a publicly accessible server, its security is not in your own hands. The company running the cloud service (and its servers) has complete control over your information.

In a way, it is more secure than a personal computer. A single hardware fault cannot jeopardize your entire data. But at the same time, it also exposes the information to outside threats. A hack that compromises the cloud servers can leak your personal data.

More concerningly, you need to trust the cloud service provider itself to respect your privacy. And in this age of Big Data, that is hardly a given. Tech giants have routinely come under fire for violating the privacy of user data they have access to, making it a risk to store important information on the cloud.

Then there are the security vulnerabilities even cloud services are exposed to. Like any web service, cloud computing can be subject to Distributed-Denial-of-Service (DDoS) attacks that cripple its capabilities. This forces the affected service to go offline, making your application unavailable for an unknown period of time.

Minimizing Risk

Okay, so cloud computing is potentially vulnerable. What then, is the solution? Should you stop using cloud services completely?

Of course not. For all the theoretical security risks inherent in cloud computing, it is practically one of the most secure forms of computing. Thanks to the redundancies put in place on cloud servers, there are very few points of failure.

Data loss or theft from a cloud service requires a catastrophe, instead of a spilled cup of tea that might spell the doom of the information stored on your laptop. It is usually also harder for hackers to break in, as cloud service providers tend to use better security measures than a PC.

Personal computers can also fall prey to ransomware attacks, which lock up your personal data and demand payment in cryptocurrencies to allow you access. Other malware can just corrupt all files outright, which makes cloud computing even more indispensable.

To improve your own data security, encryption can be used. For databases and cloud storage services, encrypt the data on your own system before uploading. For entire applications running off the cloud, try services that allow you to encrypt the information used. That way, even a hack or a data leak poses no risk to your private data. 

Is Cloud Computing Secure?

Asking if cloud computing is secure is like asking whether flights are a safe way to travel. Statistically speaking, it’s the safest form there is, though, of course, nothing is completely risk-free.

Cloud computing’s biggest security risks are posed not by hackers or technical faults, but rather by willful mismanagement. The nature of cloud servers makes it very difficult for hackers to get in, and virtually guarantees safety against hardware failures.

The only thing that can compromise data on the cloud is the service provider itself. And while tech giants like Google or Amazon have established themselves as trustworthy companies in this niche, putting all your eggs in one basket is never a good idea.

Simple measures like encrypting your data and trusting cloud service providers with a transparent privacy policy can help secure your files and other information from unwanted access. If you keep your eyes open, it’s easy to mitigate the security risks of cloud computing and enjoy its benefits.
