Cloud Engineer

Infrastructure Modules & Reusability

Pourquoi : You publish a module registry with versioning and upgrade paths, so fifty teams get a security fix by bumping a version rather than by patching fifty copies.

Multi-Account/Project Strategy

Pourquoi : You design the account hierarchy and account vending, so a compromised dev account cannot touch production and a new team gets a guarded account in minutes.

VPN & Peering

Pourquoi : You replace a mesh of peerings with a transit gateway and plan the routing, so a new region or data center joins without rebuilding every connection.

Private Connectivity (PrivateLink/Endpoints)

Pourquoi : You route S3 and partner API traffic through endpoints and PrivateLink, so regulated data never crosses the public internet and the compliance review passes.

Cloud Security Posture Management

Pourquoi : You turn CSPM from a list of alerts into org-wide guardrails with ownership and remediation SLAs, so the same misconfiguration stops reappearing across accounts.

Network Segmentation

Pourquoi : You segment workloads with tight firewall rules and a WAF, so an attacker who lands on one compromised host cannot move laterally to the payment systems.

Auto-Scaling Strategies

Pourquoi : You choose scaling policies per workload, such as scheduled for a known launch and target tracking for bursty APIs, so a traffic spike does not cause an outage or a runaway bill.

FinOps Practices

Pourquoi : You set up showback and unit-cost metrics per team, so engineering sees cost per customer and chooses optimizations, instead of finance cutting budgets blindly.

Multi-Cloud Strategy

Pourquoi : You judge whether a second cloud is worth its operational cost for a given requirement, and avoid lock-in where it matters, rather than adopting multi-cloud by default.

Disaster Recovery & Business Continuity

Pourquoi : You pick a DR strategy such as pilot light or warm standby from the business RTO and RPO, and test it, so a region failure is a rehearsed procedure and not a surprise.

Cloud-Native Security Architecture

Pourquoi : You build zero-trust and shift-left checks into the platform design, so insecure infrastructure code is blocked in the pipeline before it reaches an account.

Well-Architected at Depth

Pourquoi : You run a Well-Architected review on a critical workload across all six pillars and turn the findings into a prioritized plan the team commits to.
