Redno izvajamo tr\u017ene raziskave, pripravljamo tabele s cenami in mno\u017eico parametrov za desetine podatkovnih centrov. Pomislil sem, da bi bilo \u0161koda, da bi podatki propadli. Nekdo bi lahko potreboval te podatke, drugi pa lahko uporabijo strukturo kot osnovo. V tabelah <\/u><\/a><\/noindex>so predstavljeni podatki od leta 2016. Toda tabel je bilo premalo, zato smo pripravili \u0161e grafikon in kalkulator za tarife za gostovanje stre\u017enikov<\/u><\/a><\/noindex>, poleg tega smo dodali odprte podatke iz dav\u010dne uprave o prihodkih, davkih in zaposlenih, podatke iz RIPE (status LIR, podsneti in skupno \u0161tevilo IPv4) ter podatke iz ocene ping-admin (Uptime in okvare).<\/p>\n

Kdo je bil v vzorcu<\/h3>\n

V tabeli za september 2020 so bili vklju\u010deni vsi, ki so v TOP-20 na Yandexu in Googlu, ki so prisotni na oglasnih mestih in ki imajo cene na spletni strani. \u010ce podjetje ni na spletu ali cene niso na voljo, zagotovo ni konkurent na odprtem trgu. Tak\u0161no podjetje ima morda tudi dobre naro\u010dila, na primer iz dr\u017eavnih razpisov, vendar je to lo\u010den vir dohodka, kjer lahko celo postanejo vodilni, vendar to nima veze s konkurenco na trgu. <\/p>\n

\u010ce so nekatere cene skrite, ti podatki niso prikazani v tem razponu. Na primer, \u010de je navedeno, da tarifa vklju\u010duje 350W ali 100Mbit\/s ali 1 IP-naslov in ni cen za dodatno mo\u010d, \u0161iritev kanala ali dodatne IPv4.<\/p>\n

Te\u017eave s cenotvorbo<\/h3>\n

V cenah za storitve colocation so stranke najbolj jezile skrite stro\u0161ke. To je bila ogromna te\u017eava v naughties z prometom. Nih\u010de ni vnaprej vedel, kak\u0161en bo njegov promet in vsi so se bali, da bi \"naleteli\". A \u010dude\u017eev ni. Cena 100Mbit je takrat zna\u0161ala pribli\u017eno 50.000 RUB. Danes je gigabit \u017ee cenej\u0161i. \u010cas te\u010de, cene pa so pri mnogih \u0161e vedno zelo zame\u0161ane, na spletnih straneh ponudnikov pa ni iz\u010drpnega cenika. Tarife se oblikujejo razli\u010dno, pri dolo\u010denih parametrih je cena ugodna pri enem ponudniku, pri pove\u010danju parametrov pa je \u017ee ugodnej\u0161a pri drugem. <\/p>\n

In, seveda, ne smemo pozabiti, da cena ni edini pokazatelj. Treba je upo\u0161tevati tudi druge parametre, \u010deprav je te\u017eje primerjati. Ihor je nekako pri\u0161el v na\u0161o tabelo. Tudi v bazo ga no\u010dem dodati. A potem sem pomislil, da bo to slab primer, podjetje z enim zaposlenim, 22 tiso\u010d davki in 43 tiso\u010d prispevki, kar je precej reprezentativno. Pa vendar \"ljudje to pojejo\".<\/p>\n

Splo\u0161ne tendence in te\u017eave na trgu<\/h3>\n

Na grafih je vizualno prikazana splo\u0161na trendna \u010drta trga.<\/p>\n

\"Primerjava<\/p>\n

Prvi graf prikazuje odvisnost cene od mo\u010di ob drugih enakih parametrih. Mo\u010d je ob\u010dutljiva tema tako za stranke kot tudi za podatkovne centre. Elektrika je trenutno ena od glavnih sestavin mese\u010dnih stro\u0161kov podatkovnih centrov, vlada pa stabilno dviguje tarife zanj. \u010ceprav poceni elektrika v kon\u010dni fazi pomeni proizvodnjo, delovna mesta in davke. Tako nastopamo kot energetska velesila, vendar se ne moremo pohvaliti s posebej konkuren\u010dnimi cenami v primerjavi z zahodnimi podatkovnimi centri.<\/p>\n

Na eni strani se torej zara\u010dunava zrak, saj se \u0161teje po nominalni mo\u010di, ne pa po porabljeni. Te\u017eko in drago je natan\u010dno izra\u010dunati porabljeno mo\u010d posameznega stre\u017enika, saj je potrebno na vsako vti\u010dnico namestiti \u0161tevec. Po drugi strani pa lahko stre\u017enik potencialno deluje skoraj na polno mo\u010d napajalnega bloka. Potrebno je \u0161e upo\u0161tevati, da je treba dodati 30% za hlajenje, 10% za industrijske UPS naprave in \u0161e 10% za razsvetljavo in pisarni\u0161ke potrebe. Ampak zaupam ti skrivnost, da povpre\u010den stre\u017enik porabi 100 W, saj za omaro pripeljejo 5 kW, kar zadostuje. <\/p>\n

Ve\u010dina ponudnikov gostovanja zara\u010dunava mo\u010d. Na trgu pa so tudi tisti, ki ne zara\u010dunavajo. Seveda ima vti\u010dnica \u0161e vedno omejitve. Ne morete dobiti megavata po ceni najema ene enote.<\/p>\n

Pri nekaterih tistih, ki ne zara\u010dunavajo mo\u010di, se na spletnih straneh sre\u010dujejo tudi opombe, da se GPU stre\u017eniki, blade in druge enote zara\u010dunavajo po posebnih tarifah.<\/p>\n

\"Primerjava<\/p>\n

Drugi graf prikazuje odvisnost cene od hitrosti priklju\u010dka. Hitrost povezav je \u0161e bolj zapletena tema kot elektrika. Elektrika nima pojma o kakovosti. Lahko trepeta, a za to so tu UPS in DG. Dva gigabitna kanala pa imata lahko zelo in zelo razli\u010dno kakovost. En lahko vse prenese v menjalnico, imeti slabo vidljivost, velike latence in omejitve za mednarodni promet. Za kanale ni UPS in DG za take primere. Zato je primerjava cen kanalov v veliki meri brezpredmetna. <\/p>\n

Ko smo izvajali raziskavo trga o stro\u0161kih gigabita v Moskvi, so nam zastavili vpra\u0161anja: \"Kak\u0161en promet bo?\", \"Kak\u0161ni so vrhovi?\". <\/p>\n

Na nivoju me\u0111uoperatera tako\u0111er postoji nered s cijenama. Kanali su veoma razli\u010diti po tro\u0161kovima i kvaliteti.<\/p>\n

Na \u0161to treba obratiti pa\u017enju<\/h3>\n

Treba razumjeti da ovdje, naravno, ne mo\u017ee postojati jedno ispravno mi\u0161ljenje; sve zavisi od zadatka, a \u010dak i u sli\u010dnim zadacima, svako na kraju donosi odluku sam, koje rizike prihvata, a koje ne. <\/p>\n

Po na\u0161em mi\u0161ljenju, certifikacija prema Tier III ima zna\u010dajnu ulogu. I to nije samo na\u0161e mi\u0161ljenje, jer reklame su pune Tier III. Mo\u017eete pretra\u017eivati Yandex: \"postavljanje servera u data centru\", pritisnuti Ctrl+F i izbrojati koliko se puta pojavljuje rije\u010d Tier. <\/p>\n

Me\u0111utim, s ovom certifikacijom i pozicioniranjem kao Tier III mnogi su upali u zamku. Normalan data centar prema Tier III treba imati tri certifikata: za projekat, za mogu\u0107nosti i za eksploataciju, pri \u010demu se posljednji mora potvr\u0111ivati svake dvije godine. A mnogi nemaju ni certifikat za projekat. <\/p>\n

Promet prikazuju velike i male kompanije. Srednjih iz nekog razloga nema. Prednosti i nedostaci velikih i malih su jasni. Neka velika preduze\u0107a, ina\u010de, uop\u0107e se ne bave maloprodajom. Fokusirani su na velike klijente i prodaju uslugu colocation samo po kabinetima. I to je ispravno. Kada smo bili u BST-u, stalno su im smetali na\u0161 marketing. Nisu umjeli i nisu mogli pru\u017eiti dobru uslugu u maloprodaji. To su razli\u010diti poslovi i razli\u010dite usluge. Ne mo\u017ee se zakivati \u010davle \u010deki\u0107em. Od sebe jo\u0161 ka\u017eem, da pri ostalim jednakim uslovima podr\u017eite mala preduze\u0107a radi raznolikosti i konkurencije.<\/p>\n

Zaklju\u010dek<\/h3>\n

Nisu svi dodani u bazu. Zato mo\u017eete slati podatke tko bi trebao biti dodat. Ali oni koji \u017eele, trebaju imati cene na sajtu.<\/p>\n

Ako znate jo\u0161 izvora podataka koje bi trebalo dodati, javite, potrudi\u0107emo se dodati.<\/p>\n
