What

What it is

Hatua za kuunganisha domain na kuhakikisha app iko salama kwa production. Inajumuisha SSL, health check, na hatua za mwisho kabla ya uzinduzi.

What it is not

Si mpango kamili wa SRE. Si monitoring ya juu ya kiwango cha enterprise.

2-minute theory

• Domain ya kawaida inaongeza uaminifu.
• SSL inalinda data kwa transit.
• Checklist hupunguza makosa ya dakika ya mwisho.

Key terms

• SSL: Ulinzi wa data wakati wa kusafiri kwenye mtandao.
• Health check: Ukaguzi wa haraka wa hali ya app.

5. Kamilisha checklist ya readiness.

Do and don't

Do

• Tumia domain rahisi kukumbuka
• Hakikisha SSL ni active

Don't

• Ku-launch bila health check
• Kuacha DNS records bila uhakiki

Common mistakes and fixes

• Mistake: DNS imewekwa vibaya. Fix: Thibitisha records na subdomain.
