Building a Governed AWS Landing Zone with Entra ID Federation
Learn how to build a governed AWS landing zone using Entra ID federation, IAM Identity Center, SCIM provisioning, and Service Control Policies for enterprise-grade security.

A practical comparison of hub-and-spoke, full mesh, and transit gateway topologies for multi-cluster Kubernetes, plus the CNI, MTU, and routing decisions that determine whether any of them hold up in production.
All CI/CD pipelines and production clusters are running nominally.

Practical enterprise runbooks for graduates and junior engineers—clearly separated from KBY’s senior editorial stream.

Learn how to build a governed AWS landing zone using Entra ID federation, IAM Identity Center, SCIM provisioning, and Service Control Policies for enterprise-grade security.
A hands-on runbook for junior engineers to identify, retire and remove stale Intune and Entra ID devices without breaking Conditional Access.
A staged runbook for clearing legacy per-user MFA and hardening Entra ID authentication methods without locking out users or losing break-glass access.
A single Terraform apply that flips all four account-level Block Public Access flags to false on AWS S3 reactivates every dormant wildcard GetObject statement written years earlier, and no bucket-level control remains to stop it because RestrictPublicBuckets no longer applies.
You’re on call. Read the signals, choose your first intervention, and reveal the reasoning behind every option.
A sketch data structure that estimates how many distinct items exist in a dataset using a small, fixed amount of memory instead of storing every unique item.
