I-Yocto vs. Ubuntu: Yeyiphi i-Linux Distribution efanelekileyo kwiiNkqubo ezifakwe kwi-Embedded, i-Iot, kunye ne-Edge Computing?

Kwihlabathi lophuhliso lweLinux ehlanganisiweyo, ukukhetha inkqubo yokusebenza efanelekileyo ngamanye amaxesha sisigqibo sokuqala—nesona sibalulekileyo—. I-Yocto Project kunye ne-Ubuntu zezona zisombululo zimbini zidumileyo. Nangona zombini zisekelwe kwiLinux, iifilosofi zazo zoyilo kunye neemeko zokusetyenziswa zahlukile kakhulu. Iinjineli, abayili bemveliso, kunye nabenzi bezigqibo abasebenza kwiinkqubo ezihlanganisiweyo, ii-IoT gateways, ii-PC zemizi-mveliso, kunye nezixhobo ze-edge computing kufuneka baqonde la mahluko.

Kwinqanaba eliphezulu:

• Ubuntu lusasazo lweLinux oluvela kwiDebian, eyaziwa ngokulula kokusetyenziswa kwayo, ulawulo lweepakethe ezininzi (APT), kunye nenkxaso enamandla yoluntu. Ihlala ikhethwa kwiindawo zokucwangcisa ngokukhawuleza, ukuvavanya, kunye nophuhliso.
• 
  Kwelinye icala, iprojekthi yeYocto ayilosasazo kodwa lusasazo lwe-meta—inkqubo yokwakha eguquguqukayo evumela abaphuhlisi ukuba benze imifanekiso yeLinux eyenzelwe ngokweemfuno ezithile zehardware, ukusebenza, kunye neenyawo.
• Olu mahluko lubalulekile kuba iimfuno zesixhobo esifakwe kwi-embedded ezinezixhobo zahlukile kakhulu kwezo ze-workstation okanye i-server. I-Yocto ivavanywa ngokwahlukileyo ngabaphuhlisi abasebenza kwi-firmware yokuvelisa, indawo encinci, okanye ukugcinwa kwexesha elide kunabaphuhlisi ababeka phambili i-prototyping ekhawulezayo, ukuhambelana kwesoftware, kunye nokulula kokusetyenziswa ne-Ubuntu.
• Ekugqibeleni, uthelekiso phakathi kweYocto kunye neUbuntu luphelela ekufumaneni ibhalansi efanelekileyo phakathi kokuguquguquka, ukulungiswa kokusebenza, kunye nesantya sophuhliso. Ke ngoko, oku kubalulekile kuye nabani na oxhalabele ikamva leenkqubo zeLinux ezifakiweyo.

Ubuntu lusasazo lweLinux olusekelwe kwiDebian olugcinwa yiCanonical, olufumaneka kwiinguqulelo zedesktop, iserver, kunye ne-Ubuntu Core. Luyaziwa kakhulu ngezi zinto zilandelayo:

• kulula ukuyisebenzisa kwaye ikhawuleza ukuseta
• Ulawulo lwephakheji ye-APT ukuze kube lula ukufaka isoftware
• Iinguqulelo zeNkxaso yexesha elide (LTS) ziqinisekisa uzinzo iminyaka emihlanu nangaphezulu.
• Inkxaso enkulu yoluntu kunye namaxwebhu

Kwabaphuhlisi, i-Ubuntu lukhetho lwendalo xa ukwenza iiprototypes ngokukhawuleza, ukuhambelana kwezicelo ngokubanzi, kunye nokusetyenziswa okungaphandle kwebhokisi zezona zinto ziphambili. Ihlala isetyenziswa kwiiseva, izixhobo ze-IoT, kunye neenkqubo zekhompyutha ezisemaphethelweni apho uhlaziyo lokhuseleko kunye neenkonzo ezilawulwayo ezivela kwiCanonical zidlala indima ebalulekileyo.

Ngokwahlukileyo koko, iprojekthi yeYocto ayilosasazo, kodwa yi-meta-distribution -A framework esetyenziselwa ukwenza imifanekiso yeLinux eyenziwe ngokwezifiso. Endaweni yokuthumela inkqubo yokusebenza echazwe kwangaphambili, iYocto ivumela abaphuhlisi ukuba:
