🏠 IT Knowledge DB

A multi-dimensional map of modern IT: networks, systems, infrastructure, cloud, containers, data, code, automation, and security. Ten vertical domains meet horizontal cross-cutting concepts and vertical abstraction layers.

📚 Domains

Domain	MOC	Scope
Networking	🌐 Networking MOC	Routing, switching, 802.1X, NAC, DNS, VPN
Linux	🐧 Linux MOC	systemd, kernel, shells, networking, security
Server Infrastructure	🖥️ Server Infrastructure MOC	Hypervisors, storage, hardware, backup/DR
Cloud	☁️ Cloud MOC	AWS & Azure — VPC/VNet, IAM, hybrid connectivity
Containers	📦 Containers MOC	Docker, Kubernetes, registries, runtimes
DevOps	🔄 DevOps MOC	CI/CD, IaC, GitOps, release management
Cybersecurity	🔐 Cybersecurity MOC	Threats, controls, frameworks, tooling
Database	🗄️ Database MOC	SQL, NoSQL, indexing, transactions, replication
Programming	💻 Programming MOC	Python, Bash, Git, paradigms, ops-focused coding
Automation	⚙️ Automation MOC	Ansible, Terraform, network automation, scripting

🔗 Cross-cutting Layers

Layer	MOC	What lives here
Concepts	🔗 Cross-cutting Concepts MOC	Ideas that cut across every domain (Auth, Encryption, HA, DNS…)
Abstraction Layers	📚 Layers MOC	L2/L3/L4/L7, IaaS/PaaS/SaaS — the “epochs” of IT

🧭 How to read this map

• Vertical → deep-dive inside one domain (e.g. OSPF → Stub Areas → NSSA).
• Horizontal → follow a concept across domains (e.g. Authentication shows up in 802.1X, PAM, IAM, OAuth).
• Diagonal → connect a specific tool to an abstraction layer (e.g. Envoy → L7 → service mesh).
