Kuwerenga Chilolezo cha MongoDB, zikuwoneka kuti palibe cholakwika ndikusintha pokhapokha mutakhala "wamkulu, wopereka yankho lamtambo wozizira."
Komabe, ndifulumire kukukhumudwitsani: zotsatira zake mwachindunji kwa inu zikhala zowopsa komanso zoyipa kuposa momwe mungaganizire.

Kodi chiphaso chatsopanocho chimakhudza bwanji mapulogalamu omangidwa pogwiritsa ntchito MongoDB ndikuperekedwa ngati ntchito (SaaS)?
Ndime ya copyleft mu Gawo 13 la SSPL imagwira ntchito pokhapokha mupereka magwiridwe antchito a MongoDB kapena mitundu yosinthidwa ya MongoDB kwa anthu ena ngati ntchito. Palibe ndime ya copyleft ya mapulogalamu ena a SaaS omwe amagwiritsa ntchito MongoDB ngati nkhokwe.
MongoDB nthawi zonse yakhala "kampani yotseguka yotseguka." Pamene dziko (GPL) kupita ku zilolezo zaufulu (MIT, BSD, Apache), MongoDB inasankha AGPL pa MongoDB Server Software yake, mtundu wocheperako wa GPL.
Pambuyo powerenga MongoDB yogwiritsidwa ntchito polemba IPO, mudzawona kuti kutsindika kuli pa freemium model. Izi zimatheka ndikuyimitsa mtundu wa Community Server m'malo motsatira mfundo za gulu lotseguka.
Poyankhulana mu 2019, CEO wa MongoDB Dev Ittycheria adatsimikiza kuti MongoDB Inc. sigwirizana ndi gulu lotseguka kuti lisinthe MongoDB pomwe amayang'ana kwambiri njira yawo ya freemium:
"MongoDB idapangidwa ndi MongoDB. Panalibe njira zomwe zinalipo kale. Sitinatsegule ma code kuti atithandize; tidatsegula ngati gawo la njira ya freemium,"
- Dev Ittycheria, CEO wa MongoDB.
Mu Okutobala 2018, MongoDB idasintha layisensi yake kukhala SSPL (Server Side Public License). Izi zidachitika mwadzidzidzi komanso mosagwirizana ndi gulu lotseguka, pomwe zosintha zomwe zikubwera zimalengezedwa pasadakhale, kulola iwo omwe pazifukwa zina sangathe kugwiritsa ntchito chilolezo chatsopano kukonza ndikukhazikitsa kusintha kwa mapulogalamu ena.
Kodi SSPL ndi chiyani ndipo chifukwa chiyani zingakukhudzeni?
Zolinga za laisensi ya SSPL zimafuna aliyense wopereka MongoDB ngati DBaaS kuti amasule zida zonse zozungulira malinga ndi SSPL kapena kupeza chilolezo chamalonda ku MongoDB. Kwa opereka mayankho pamtambo, zakale sizothandiza chifukwa kupereka zilolezo ku MongoDB kumalola MongoDB Inc. yesetsani kuwongolera mitengo ya ogwiritsa ntchito kumapeto, kutanthauza kuti palibe mpikisano weniweni.
Pamene DBaaS ikukhala njira yotsogola yogwiritsira ntchito mapulogalamu a database, kutsekera kwa woperekerayu ndi vuto lalikulu!
Mutha kuganiza kuti, "Palibe vuto lalikulu: MongoDB Atlas siyokwera mtengo kwambiri." Zowonadi, izi zitha kukhala ... koma pakadali pano.
MongoDB sinapindulebebe, popeza idataya ndalama zopitilira $175 miliyoni chaka chatha. MongoDB pakadali pano ikuyika ndalama zambiri pakukulitsa. Izi zikutanthauza, pakati pa zinthu zina, kusunga mitengo yotsika kwambiri. Komabe, makampani amasiku ano padziko lonse lapansi ayenera kukhala opindulitsa posachedwa, ndipo pakapanda mpikisano, muyenera kulipira.
Si phindu lokha lomwe muyenera kuda nkhawa nalo. Wopambana-amatenga-zonse zopezera gawo lalikulu pamsika pamtengo uliwonse zikutanthauza kukweza mitengo momwe angathere (ndi kupitirira!).
Padziko lazosungirako, masewerawa adaseweredwa bwino zaka makumi angapo zapitazo ndi Oracle, yomwe idapulumutsa anthu kuti asamangidwe ndi zida za "blue giant" (IBM). Mapulogalamu a Oracle analipo pamitundu yosiyanasiyana ya hardware ndipo poyamba anaperekedwa pamtengo wokwanira ... ndipo kenako anakhala bane wa CIOs ndi CFOs padziko lonse lapansi.
Tsopano MongoDB ikusewera masewera omwewo, pa liwiro lothamanga. Mnzanga komanso mnzanga Matt Yonkovit adafunsa posachedwa, "Kodi MongoDB ndi Oracle yotsatira?"
Pomaliza, SSPL sichinthu chomwe chimangokhudza ochepa ogulitsa mitambo omwe sangathe kupikisana mwachindunji ndi MongoDB mu danga la DBaaS. SSPL imakhudza ogwiritsa ntchito onse a MongoDB poika maloko ogulitsa komanso kuwopsa kwamitengo yoletsedwa yamtsogolo.
