Shabakadda gudbinta nuxurka ( CDN ) waa ururin adeegayaal ah oo lagu qaybiyey adduunka oo dhan kuwaas oo u gudbiya qaybo ka mid ah mareegahaaga booqdayaasha goobta ku yaal meel u dhow adeegayaashaas.

Isticmaalka ugu badan ee CDN waa gudbinta sawirada mareegaha. Tani waa sababta oo ah sawiradu inta badan waa qaybta ugu gaabis ah ee bogga shabakada.

Waa maxay CDN?^{(What Is a CDN?)}

CDN ma^(CDN) aha martigeliyaha webka. Waxa ay si fudud u kaydinaysaa qaybaha degelkaaga ee aad u dejisay in uu u adeego CDN . Faylashan la kaydiyay (la kaydiyay) waxa lagu shubaa dhammaan adeegayaasha kala duwan ee adduunka oo dhan.

Marka booqde waddan kale soo booqdo mareegahaaga, waxay si toos ah qoraalka uga helayaan martigeliyahaaga mareegahaaga, laakiin waxa laga yaabaa inay ka helaan tiro faylal kale ah server- ka CDN ee ugu dhow goobta ay joogaan.^(CDN)

Galalkan waxaa ka mid noqon kara:

Faylasha Javascript
Sawirada
Muuqaalo
Xaashiyaha qaabka

Baahida adeegyada CDN ayaa cirka isku shareertay markii Google uu bilaabay adeegsiga xawaaraha bogga sida hal doorsoome ee algorithm darajadooda.

Tartankan si uu u noqdo bogga ugu dhaqsaha badan mawduuca wuxuu u baahday milkiilayaasha mareegaha si ay u raadiyaan beddelka sawirada si tartiib tartiib ah ugu shubaya goobta. Shabakadda CDN^(CDN) ee la qaybiyay, la kaydiyay, ayaa ahayd xalka ugu fiican.

Waa maxay sababta CDN ay muhiim ugu tahay boggaaga^{(Why a CDN Is Essential For Your Site)}

Haddii aad leedahay mareegaha, xawaaraha boggu ku shuban yahay waa muhiim sababo dhowr ah dartood. Sida kor ku xusan, waxay kor u qaadi doontaa dhibcaha guud ee Google .

Marka labaad, waxay wanaajisaa waayo-aragnimada booqdayaashu ay ku leeyihiin mareegahaaga. Tani waxay ka dhigi doontaa inay ku sii jiraan mareegahaaga wakhti dheer, oo ay booqato bogag badan oo ku yaal.

Halkan waxaa ah dhowr siyaabood oo kale oo CDN uu muhiim ugu yahay mareegahaaga.

Badbaadiya Bandwidhthka^{(Saves Bandwidth)}

Adigoo isticmaalaya CDN , waxaad ka bedeshaa isticmaalka bandwidth ee server-ka martigeliyahaaga oo aad u gudubto shabakada la qaybiyay ee adeegayaasha CDN .

Markaad dejiso koontadaada CDN oo aad ku xidho boggaaga , waxaad arki doontaa in xajmigu bilaabay inuu ku ururo dashboardka akoonkaaga.

Tani waa baahida bandwidth ee aad ka saarayso server-ka martigeliyahaaga. Adeegga martigelinta shabakada sida ay qaali u yihiin - oo inta badan lagu dalaco isticmaalka xad dhaafka badan - jarista isticmaalka xadhkaha goosashada inta badan waxay la mid tahay kaydka qiimaha weyn.

Qiimaha bandwidth CDN^(CDN) aad ayuu uga jaban yahay kharashyada martigelinta webka. Tani waa sababta oo ah adeegyada CDN waxay dejiyeen shabakadooda server-ka si ay u maareeyaan waxyaabaha xajmigoodu sarreeyo sida sawirada. Waxay sidan u sameeyaan siyaabaha soo socda.

CDN^(CDNs) -yadu waxay adeegsadaan hagaajinta sida isu dheellitirka culeyska server-ka iyo wadeyaasha gobolka ee joogtada ah, kuwaas oo dedejiya wareejinta oo yareeya khaladaadka.
Iyada oo loo marayo farsamooyinka wax-is-beddelka cabbirka faylka sida isku-buufinta faylka iyo yaraynta, CDN^(CDNs) -yadu waxay yareeyaan qaddarka xogta la wareejiyay.
Isticmaalka shahaadooyinka SSL/TLS , CDN^(CDNs) -yadu waxay yarayn karaan bilawga wareejinta beenta ah, taas oo ka fogaanaysa baahida loo qabo in dib loo bilaabo wareejinta oo loo diro xitaa xog dheeraad ah.

Waxay yaraynaysaa wakhtiga dhimista^{(Reduces Downtime)}

Marka ay timaado in la isku halleyn karo, waxaa jira waxyaabo yar yar oo yareynaya wakhtiga degelkaaga in ka badan isticmaalka adeegga CDN .

Wakhtigan korodhay waxa sabab u ah dhawr sababood.

Shabakadda CDN^(CDN) ee la qaybiyey waxay ka dhigan tahay in inta badan xajmigaaga - sawirada - ay ka imanayaan server-yo badan oo adduunka oo dhan ah. Adeegyada CDN^(CDN) waxay isticmaalaan farsamo loo yaqaan "load balancecing", taas oo macnaheedu yahay marka ay jirto baahi xad dhaaf ah oo ka timaada hal server, adeegayaasha kale ayaa loo isticmaalaa in lagu dheellitiro culeyska.

Mar kasta oo taraafikada mareegahaagu si weyn u kororto, waxay gelinaysaa baahi badan qaybo badan oo qalab ah. Gaar ahaan, serfarka shabakadda ee ku jira xarunta xogta martigeliyahaaga, iyo adeegayaasha la qaybiyey ee uu maamulo adeegga CDN kaaga .

Oo mar haddii sawirada iyo faylalku ay yihiin xogta ugu badan ee la wareejiyo, waa meesha baahida ugu badan ay ka dhici doonto.

Xaqiiqda ah in CDN^(CDNs) -yadu ay maareeyaan baahidaas adeegayaal badan oo isku dheelitiran waxay la macno tahay in goobtaadu ay awood u yeelan doonto inay xakamayso taraafikada si aad uga badan haddii aadan isticmaalin adeegga CDN .

Wanaajinta Amniga^{(Improves Security)}

Waxaa laga yaabaa inaad la yaabto inaad ogaato in isticmaalka CDN uu sidoo kale kordhin karo ammaanka goobtaada.

Si aad tan u fahanto, marka hore waa muhiim inaad fahanto socodka xogta marka ay booqdeyaashu yimaadaan mareegahaaga.

Hal server shabakadeed, booqdayaashu waxay codsadaan bogga shabakadda, iyo server-kaagu wuxuu u baahan yahay inuu kaga jawaabo dhammaan xogta - oo ay ku jiraan qoraalka, sawirada, Javascript, iyo xaashiyaha qaabka. Dhammaan baahidaas bandwidth waxay saamaysaa hal server-kaaga.

U sawir tan sida biyo-xireen oo leh dekado biyood oo badan. Xaaladdan, waxay noqon doontaa biyo-xidheen leh hal deked oo ay biyuhu dhex maraan. Uma baahnid in badan oo biyo badan kor u kaca in biyo xidheenka la saaro culayska iyo in biyuhu bilaabaan inay korka dul socdaan.

Tani waa sababta inta badan biyo-xireennada laga dhiso dekedo badan oo la furi karo marka heerka biyuhu kor u kaco dhinaca kale.

Haddii aad leedahay degel lagugu hayo hal server oo shabakad ah, waxay ku qaadanaysaa dadaal aad uga yar dhinaca weerarka DDOS si uu u dejiyo degelkaaga.

Weerarada DDOS waxaa laga soo qaaday "bots" badan oo kala duwan oo adduunka ka kala yimid, iyaga oo ka dhigaya boqolaal ama xitaa kumanaan isticmaaleyaal ah oo codsiyo ka dhan ah server-kaaga mareegta isku mar ah sameynaya.

Si kastaba ha noqotee, adoo isticmaalaya adeegga CDN oo leh mareegaha loo qaybiyay adduunka oo dhan, dhammaan server-yadaas waxay la mid yihiin dekedo dheeraad ah oo biyo-xireen ah.

Hadda server-kaagu wuxuu kaliya u baahan yahay inuu u adeego qoraalka, iyo adeegayaal CDN badan ayaa bixiya sawirro iyo faylal kale. Dhammaan adeegayaashan ayaa asal ahaan wadaaga baahida bandwidth.

Tani ma bixin doonto 100% ka-hortagga weerarrada DDOS , laakiin waxay u baahan doontaa in dadaalka ay hackers-ku galiyeen weerarka uu noqdo mid aad u weyn ka hor inta uusan website-kaagu hoos u dhicin.

Intaa waxaa dheer, haddii aad hubiso inaad dejiso CDN-gaaga shahaadooyinka TLS ^(CDN)TLS/SSL , dhammaan taraafikada waa la sir doona oo laga ilaalin doonaa tuugada inay farageliyaan taraafikada shabakadda.

Sida Loo Sameeyo Adeegga CDN-kaaga^{(How to Set Up Your CDN Service)}

In kasta oo adeegga CDN laga yaabo inuu u ekaado mid adag, dejintiisu waa sahlan tahay.

Marka hore, waxaad u baahan tahay inaad doorato adeegga CDN . Waxaa jira dhowr kuwa waaweyn oo laga dooran karo.

Cloudflare : Mid ka mid ah adeegyada ^(Cloudflare)CDN ee ugu weyn uguna caansan ee ay isticmaalaan ganacsiyo waaweyn oo badan oo adduunka ah.
Degdeg^(Fastly) : Waxay bixisaa tiro alaab ah oo hagaajinta shabakada ah, oo ay ku jiraan gudbinta macluumaadka CDN .
KeyCDN : Waxay maamushaa xarumaha xogta 34 ee ku yaala aduunka oo dhan, oo leh waxqabadka xawaaraha shabakada ee la xaqiijiyay.
MetaCDN : Si ka duwan adeegyada kale ee CDN ee ku dalaca isticmaalka, adeegani waxa uu dalacayaa lacag siman bishii.
StackPath : Horey MaxCDN , StackPath waxaa isticmaala shirkado badan iyo mareegaha adduunka oo dhan.

Mid kasta oo ka mid ah adeegyadan ayaa ku siin doona wanaajinta CDN ku filan goobtaada. Haddii goobtaadu yar tahay, way fiican tahay inaad raacdo qaabka lacag bixinta ku salaysan isticmaalka maadaama ay u badan tahay in xajmigu hooseeyo. Haddii aad leedahay degel weyn ama ganacsi, qaabka heerka go'an ayaa fiicnaan lahaa.

Markaad iska diiwaan geliso adeegga CDN , waxaad u baahan doontaa inaad aagga CDN -kaaga ku samayso akoonkaaga.

Dejinta koontada waxay si fudud ku lug leedahay bixinta magaca domainkaaga, iyo habaynta kaydinta iyo isku-buufinta. Caadi ahaan, way fiican tahay in goobahan looga tago sidii hore.

Qor^(Make) magaca CNAME ee ay bixiso CDN kaaga . Waxaad u baahan doontaa tan hadhow

Ugu dambeyntii, waxaad u baahan doontaa inaad ku rakibto plugin CDN on your site. Tusaale ahaan, haddii aad maamusho goobta WordPress , W3 Total Cache waa ikhtiyaar caan ah.

Markaad rakibto plugin-ka, waxaad arki doontaa meel bannaan oo aad ka geli karto CNAME -ga uu bixiyo adeegga CDN -kaga .

Waxa kale oo aad heli doontaa qayb aad awood u siin karto nooca faylalka ee boggaaga aad rabto in adeegga CDN uu kaydiyo oo siiyo booqdayaasha.

Markaad badbaadisay dhammaan isbeddellada, waa inaad aragto jaantusyada xawaaraha CDN ee bilaabay inay ka tarjumayaan booqdayaasha waqti ka dib. Waxaa laga yaabaa in waqti ay isbeddeladu ku soo noqnoqdaan intarneedka^(Internet) oo dhan , laakiin isbeddelada DNS waa in la cusbooneysiiyaa ka dib 24 saacadood.

Marka la eego waxtarka iyo faa'iidooyinka amniga ee uu bixiyo adeegga CDN , ma awoodid inaadan u habeynin mareegahaaga.

What Is a CDN & Why Is One Essential If You Own a Domain?

A content delivery network (CDN) is a collection of servers distributed across the world thаt deliver pieces of your website to site visitors loсated near those servers.

The most common use of a CDN is for the delivery of images from a website. This is because images are usually the slowest-loading component of a web page.

What Is a CDN?

A CDN is not a web host. It simply caches the parts of your website that you’ve set up to be served by a CDN. These saved (cached) files are uploaded to all of the different servers across the world.

When a visitor from another country visits your website, they receive the text directly from your web host, but they may receive a number of other files from the CDN server nearest their location.

These files may include:

Javascript files
Images
Videos
Stylesheets

The demand for CDN services skyrocketed when Google started using page load speed as one variable in their ranking algorithm.

This race to become the fastest loading page on a topic required website owners to seek out alternatives for slow-loading images on the site. The distributed, cached, CDN network was the perfect solution.

Why a CDN Is Essential For Your Site

If you own a website, the speed that pages load is important for a few reasons. As mentioned above, it’ll boost your overall ranking score with Google.

Secondly, it improves the experience visitors have on your website. This will make them stay on your website longer, and visit more pages on it.

Here are a few other ways a CDN is essential for your website.

Saves Bandwidth

By using a CDN, you’re shifting the bandwidth use off of your web host’s server and onto the distributed network of CDN servers instead.

Once you set up your CDN account and set it up with your domain, you’ll see that bandwidth start to accumulate in your account dashboard.

This is the bandwidth demand you’re removing from your web host’s server. With web hosting services as expensive as they are – and very often being charged for using more bandwidth – cutting back on bandwidth usage usually equates to significant cost savings.

CDN bandwidth costs are far cheaper than web hosting costs. This is because CDN services set up their server network to manage high bandwidth content like images. They do this in the following ways.

CDNs use optimizations like server load balancing and steady state drives, which speed up the transfer and reduce errors.
Through file size manipulation techniques like file compression and minification, CDNs reduce the amount of data that’s transferred.
Using SSL/TLS certificates, CDNs can reduce false transfer starts, which avoids the need to restart a transfer and send even more data.

Reduces Downtime

When it comes to reliability, there are few things that reduce your website downtime more than using a CDN service.

This increased uptime is due to a number of reasons.

The distributed CDN network means that the bulk of your bandwidth – images – are coming from multiple servers from all over the world. CDN services use a technique called “load balancing”, which means that when there’s excessive demand from one server, other servers are used to balance out the load.

Whenever your website traffic spikes significantly, it puts a lot of demand on multiple pieces of hardware. Specifically, the web server in your web host’s data center, and the distributed servers managed by your CDN service.

And since images and files are the largest bulk of the data being transferred, that’s where the majority of demand will occur.

The fact that CDNs manage that demand across multiple load-balanced servers means that your site will be able to handle significantly more traffic than if you weren’t using a CDN service.

Improves Security

You may be surprised to learn that using a CDN can also increase your site security.

To understand this, first it’s important to understand the flow of data when visitors come to your website.

In a single web server setup, visitors make a request for a web page, and your web server needs to respond with all of the data – including text, images, javascript, and stylesheets. All of that bandwidth demand impacts your one web server.

Picture this like a dam with multiple water ports. In this scenario, it would be a dam with just a single port for water to flow through. It wouldn’t take too much of a water surge for the dam to be overburdened and water to start flowing over the top.

This is why most dams are built with multiple ports that can be opened as the water level rises on the other side.

If you have a website hosted on a single web server, it takes much less effort on the part of a DDOS attacker to take down your website.

DDOS attacks are launched from many different “bots” from around the world, simulating hundreds or even thousands of users making requests against your web server all at the same time.

However, by using a CDN service with distributed web servers around the world, all of those servers are like additional ports in the dam.

Now your web server only needs to serve text, and multiple CDN servers provide images and other files. All of these servers are essentially sharing the bandwidth demand.

This won’t provide 100% protection against DDOS attacks, but it will require that the effort the hackers put into the attack be much larger before your website goes down.

In addition, if you make sure to set your CDN up with TLS/SSL certificates, all traffic will be encrypted and protected from hackers intercepting the web traffic.

How to Set Up Your CDN Service

While a CDN service may sound complicated, setting it up is fairly easy.

First, you need to choose a CDN service. There are a few major ones to choose from.

Cloudflare: One of the largest and most well known CDN services used by many major businesses across the world.
Fastly: Offers a number of web optimization products, including CDN content delivery.
KeyCDN: Manages 34 data centers located all across the world, with proven website speed performance.
MetaCDN: Unlike other CDN services that charge based on usage, this service charges a flat monthly fee.
StackPath: Formerly MaxCDN, StackPath is used by many companies and websites around the world.

Any of these services will provide sufficient CDN optimization for your site. If your site is small, it’s better to go with a usage-based pay model since your bandwidth will likely be low. If you have a large website or business, the fixed rate model would be better.

Once you’ve signed up for a CDN service, you’ll need to set up your CDN zone in your account.

Setting up the account simply involves providing the name of your domain, and configuring caching and compression. Typically, it’s fine leaving these settings as default.

Make note of the CNAME hostname provided by your CDN. You’ll need this later.

Finally, you’ll need to install a CDN plugin on your site. For example, if you’re running a WordPress site, W3 Total Cache is a popular option.

Once you install the plugin, you’ll see a field available where you can enter the CNAME provided by your CDN service.

You’ll also find a section where you can enable what type of files on your website you want the CDN service to cache and provide to visitors.

Once you’ve saved all changes, you should see the CDN bandwidth charts start reflecting visitors over time. It may some time for the changes to replicate throughout the Internet, but the DNS changes should update after about 24 hours.

Given the performance and security benefits provided by a CDN service, you can’t afford not to configure it for your website.
