Questions fréquentes Ingénieur SRE

Quelle différence entre SRE et DevOps ?

SRE = pratiques Google spécifiques avec error budgets, SLOs. DevOps = philosophie plus large. SRE implémente DevOps avec métriques précises. Les deux convergent en pratique.

Faut-il être développeur pour devenir SRE ?

Fortement recommandé. 50% coding minimum (Python, Go). Background ops seul insuffisant. Meilleurs SRE = dev + ops experience. Automation requires programming.

Comment gérer le stress de l'on-call ?

Rotation équitable, compensation juste, documentation solide, automation maximum. Post-mortems blameless. Time off après incidents majeurs. Support psychologique disponible.

Kubernetes est-il indispensable ?

Quasi-indispensable 2025. 80% positions requièrent K8s. CKA/CKAD valorisés +25-30%. Alternative : expertise cloud-native équivalente (ECS, Cloud Run).

Quel cloud provider privilégier ?

AWS reste leader (40% jobs). GCP forte culture SRE (Google origine). Azure entreprises Microsoft. Multi-cloud idéal mais expertise approfondie sur un suffit.

Les certifications sont-elles rentables ?

Oui, ROI 3-6 mois. Google Cloud DevOps Engineer top valeur. CKA incontournable. AWS DevOps Pro reconnu. Combinaison cloud + K8s optimale.

Comment négocier son package en GAFAM ?

Total compensation = base + bonus + RSUs. Négocier RSUs crucial. Competing offers leverage. Niveau (L4/E5) plus important que titre. Relocation packages négociables.

Peut-on devenir SRE sans diplôme ingénieur ?

Possible mais plus difficile. Portfolio projets open source crucial. Certifications compensent. Bootcamps SRE émergent. Experience ops + self-learning viable.

Quelle évolution après Principal SRE ?

Distinguished/Fellow Engineer (technique pure). Engineering Manager (leadership). CTO/VP Engineering (executive). Founding engineer startup. Consulting indépendant haute valeur.

Le métier va-t-il être automatisé ?

Non, complexité croissante. AI augmente capacités mais ne remplace pas. Nouveaux challenges : ML ops, edge, quantum. Focus shift vers architecture et stratégie.
