Asmaynut n stack tatiknikt d asnifel, s ufrag, n wayen yettḥeṣṣun asuffeɣ, taɣellist neɣ timerna, war ma tḥebseḍ ameẓlu i yimseqdacen, war ma tɛawdeḍ tira n kullu deg yiwet n tikkelt. Tarrayt yeɣlin ugar d amutti aḍar s uḍar: tafeɣzt (façade) zdat n unagraw yellan, sakin yiwen n umodul deffir wayeḍ. I tɣessa (architecture) n SaaS, Go i yimeẓla (services), Next.js d TypeScript i ugrudem (interface), d Python i TI d yisefka, ttarran-d yiwet n tmesmunt yeṣṣeḥḥan — ma tessen tegrawt amek ara tt-tesseqdec, ayen ur nelli ara dima.

Mayd tamatarin ay d-yesskanen dakken stack tatiknikt ilaq ad tettwasmaynut?

Teknolojit taqburt ur d ugur s yiman-ns. Stack tettuɣal d ugur mi ara tessxeser ugar n wayen d-tettawi: yal asnifel yettawi akud ugar n wayen yettwaheyyan, d tegrawt tessegra akud-ns tettezzi i unagraw ugar n wakken ad t-tessenqeddem. Tamatarin ay iɛnan, ttwannayent:

• Asuffeɣ iẓẓayen, yeččur d ixaṭaṛen: yal asuffeɣ ɣer production yettili s ufus, aṭas n tikkal deg yiḍ, s tugdi ad yerreẓ kra nniḍen.
• Imsidaf ay yewḍen ɣer tagara n tudert-nsen: framework, tutlayt neɣ anagraw n usexdem (système d'exploitation) ur nettawi ara dɣa iseɣtiyen n taɣellist.

Tamatart tasuft, aṭas n tikkal, tettwafsay deg wadeg-ns. Mi ara mlalent mennawt, asteqsi ur yelli dɣa ma ilaq asmaynut, maca s wanwa amizwar. Uqbel ad tferneḍ teknolojiyin, aru iswiyen n tmɣawt d tewtilin: d tagi ay d tamsalt n udlis n tewtilin n useɣẓan (cahier des charges) yelhan.

Refonte n usnas: ayɣer ara tḥadreḍ tira tamaynut n kullu?

Yella ccah ad tesnegreḍ kullu, ad tebduḍ seg zéro. Deg tidet, tira tamaynut « big bang » tessbeddad afaris aṭas n wayyuren: anagraw aqbur ittkemmil ad yettnerni i yimsaɣen, amaynut yettazzal deffir yiswi yettmussun, d tuɣalin taneggarut tessmun akk ixaṭaṛen deg yiwet n taggara n yimalas (week-end). Ilugan n tmɣawt ur d-yettwannan, ur yettwarun deg kra n wadeg maca llan deg tengalt, d nutni ay yettruḥun d imezwura.

Tarrayt yettwakeyyren d amutti aḍar s uḍar, s yisem-ns s teglizit strangler pattern (seg « tazart taxennaqt », tugna ay yessiẓen Martin Fowler): anagraw amaynut yettimɣur i tama n uqbur d yettawi adeg-ns tawuri s tawuri.

2. Fren tamnaḍt tamezwarut tameẓyant, tenfeɛ, d ur tesɛi aṭas n ixaṭaṛen: anadi, tilɣa (notifications) neɣ amodul n yineɣmisen (reporting), amedya.

4. Ktel, seɣti, sakin ales s tmnaḍt d-iteddun.
5. Kkes tangalt taqburt s ufrag, ma ulac tagrawt ad tettḥerriz sin n yinagrawen war tagara.

Yal aḍar yettawi-d azal d yezmer ad yuɣal ɣer deffir: ma yella ameẓlu amaynut ur yeddi ara akken iwata, tafeɣzt tettarra trafik ɣer uqbur alamma yettwaseɣta.

Ayɣer Go d Next.js i tɣessa n SaaS?

Next.js, Go, Python d TypeScript d stack tagejdant n Codevista Innovations. Ssebbat d tid n uxeddim n yal ass, d ttemmalent i yal tagrawt ay yesneqden tamesmunt-a.

Next.js d TypeScript i frontend

Next.js yettarnu i React asekker deg uqeddac (rendu côté serveur) d usirew asbadu (génération statique). Isebtar imeɣradanen ttawḍen ɣer yiminig (navigateur) ttwabnan yakan, ayen yesɛan azal i SEO (asmuqqel deg yimsaddayen n unadi), i wakud n usken ɣef tiliɣri d i beṭṭu deg yiẓeḍwan inmettiyen.

Mi ara yettwabeddel yisem n wurti (champ) deg tama n API, d compilation ay yettruẓen, maci production.

Python yeqqim d tutlayt n tawant i yisefka d tussna tafrawant: asefrek n yisefka, alemmed awurman (machine learning), SDK n yimeẓla n yimudilen n tutlayt. Deg wadeg ad tḥetmeḍ ixeddimen-a ad ttwarun s Go, yif ad ten-tesmeẓleḍ deg yimeẓla n Python yettwasbedden i yiman-nsen, ay yettwaɣṛen s API tagensant neɣ s tebdart n yiznan.

Ma yella TI ur tessaweḍ ara ugar n kra n yiɣuṛen n API ɣer umeẓlu n yimudilen, ameẓlu n Go neɣ n TypeScript, aṭas n tikkal, yemmal-as.

Ulac stack yelhan deg yal adeg. Ha-tent-a tegnatin anida tifrat nniḍen, neɣ ad teqqimeḍ akken tella tegnit (statu quo), d tid yemmalen ugar:

Tɣessa multi-tenant: aheggi n timerna ɣer umaḍal

SaaS multi-tenant yettak ameẓlu i mennaw n tuddsiwin timsaɣin, tenants, ɣef yiwet n tɣerɣert. Mi ara tnadiḍ mennaw n tmura, ttgaren tenants d tuttriwin n usmeẓli. Amudil n usmeẓli yettwafran zik, acku iwɛer ad yettwabeddel deffir:
