Core knowledge areas
Eight chapters form the backbone of ITVedas. Each one starts at foundation level and is actively growing toward advanced, practitioner-level material — not just beginner explainers.
Networking
How data actually moves — OSI, subnetting, DNS, DHCP, NAT and firewalls through to BGP, OSPF, MPLS and SD-WAN for engineers running production networks.
Explore Networking →Cloud Computing
AWS, Azure and Google Cloud from IaaS/PaaS/SaaS basics to Kubernetes, Terraform, cost optimization and multi-region high-availability architecture.
Explore Cloud →Security
Encryption, authentication and the OWASP Top 10 through to SIEM, penetration testing, incident response and proactive threat hunting.
Explore Security →DevOps
CI/CD pipelines, Docker and GitOps through to Kubernetes at scale, service mesh (Istio/Linkerd) and platform engineering practice.
Explore DevOps →Databases
SQL fundamentals, indexing and replication through to sharding, high availability and disaster recovery architecture for production systems.
Explore Databases →Linux & OS
File permissions, systemd and shell scripting through to kernel tuning, cgroups and fleet-scale configuration automation.
Explore Linux →Hardware
CPUs, RAM and storage fundamentals through to server hardware, data center design and enterprise SAN/NAS storage architecture.
Explore Hardware →Compliance
GDPR, HIPAA, PCI DSS and ISO 27001 explained plainly, through to the SOC 2 audit process and what auditors actually ask to see.
Explore Compliance →Specialized tracks
Beyond the core eight, ITVedas covers focused platform and vendor tracks — useful if you already know which stack you're working in.
Azure
Entra ID, VNets and ExpressRoute, VM sizing, plus AZ-900/104/305 study guides.
PowerShell
Cmdlets and piping through to functions, modules and Active Directory automation.
SQL Server
Editions and licensing, installation, and Always-On availability groups.
IIS Server
Installation, application pool management, and SSL/TLS certificate configuration.
APIs
REST, HTTP methods and JSON — what an API actually is and how it's used.
CVE & Vulnerability Analysis
What a CVE is, how CVSS scoring works, plus real-world breakdowns of Log4Shell, EternalBlue and more.
AI Models & Tools
Claude, GPT-4o, Gemini and more compared — capabilities, pricing and how to choose.
Career Paths
Foundation-to-Expert skill roadmaps and certification guidance for every core topic.
Beyond articles
ITVedas is more than a library of guides — it's also a set of tools built to be genuinely useful on their own.
Problems & Solutions
Step-by-step fixes for the IT problems people actually run into — WiFi drops, DNS failures, error codes and more.
IT & Security News
Original reporting on tech and cybersecurity news, explained in plain English, updated throughout the day.
Free IT Tools
JSON/YAML formatters, a JWT decoder, DNS lookup, hash generator and more — no sign-up required.

How every knowledge area is built
- Every topic starts at foundation level — no guide assumes you already know the subject.
- Coverage is designed to grow toward advanced, practitioner-level material, not stop at "explained simply."
- New guides are checked against current, widely-accepted IT best practices before publishing.
- Everything is free, with no paywalls and no sign-up walls.
- Security- and compliance-related guides point you toward authoritative sources for anything with real-world risk.
