- ✔ Networking gear: Routers, switches and firewalls that enable connectivity.
- ✔ Storage: SSDs, HDDs, SAN and NAS solutions tailored to capacity & speed needs.
Practical tip: For small websites and experiments, a cloud VM or a modest VPS
often replaces the need for owning physical hardware. For enterprise workloads, consider
redundancy (RAID, backups) and environmental controls (cooling, UPS).
🖥️ Servers, Storage & Devices — Hardware Layer
➤ 2.2 Software — Applications & systems
Software includes operating systems, applications, middleware and system-level tools
that run on hardware. Software is typically categorised as system software or application software.
- ✔ Operating systems: Windows, Linux, macOS, Android — the foundation for apps.
- ✔ Enterprise software: ERPs, CRMs, accounting systems that support business processes.
- ✔ Productivity tools: Office suites, collaboration apps, email clients.
- ✔ Custom & open-source: Web apps, mobile apps and open-source platforms (WordPress, Drupal).
Practical tip: Keep software patched and use package managers or automated deployment
for consistency (e.g., apt, yum, npm, pip, Docker images).
➤ 2.3 Networking — Connectivity & protocols
Networking connects devices and enables data exchange. It includes local networks (LAN),
wide-area networks (WAN), and internet connectivity. Key protocols: TCP/IP, HTTP, HTTPS, DNS.
- ✔ LAN/WLAN: Local connectivity using switches and Wi-Fi access points.
- ✔ Routing & switching: How packets find their way across networks.
- ✔ VPNs & remote access: Securely connecting remote users or branch offices.
- ✔ CDNs: Content Delivery Networks that speed up global content delivery.
Practical tip: For website owners, using a CDN reduces latency and increases resilience.
For internal networks, segment traffic and use VLANs to improve security.
🌐 Networking — The Glue Between Devices
➤ 2.4 Data Management & Databases
Data management stores, retrieves and protects information. Databases are core components:
relational (SQL) and non-relational (NoSQL).
- ✔ Relational DBs: MySQL, PostgreSQL — ACID properties, suited for structured data.
- ✔ NoSQL: MongoDB, Cassandra — flexible schemas for large-scale or unstructured data.
- ✔ Data warehouses & lakes: For analytics and BI workloads (Redshift, BigQuery).
- ✔ Backup & DR: Regular backups, tested restores and disaster recovery plans.
Practical tip: Use managed database services when possible to reduce operational overhead.
Always encrypt sensitive data at rest and in transit.
➤ 2.5 Cloud Computing
Cloud computing lets organisations rent compute, storage and platform services. Main models:
IaaS, PaaS and SaaS.
- ✔ IaaS: Virtual machines and raw infrastructure (EC2, Compute Engine).
- ✔ PaaS: Managed platforms for deploying apps (App Engine, Heroku).
- ✔ SaaS: Ready-to-use software over the internet (G Suite, Salesforce).
Practical tip: Understand cloud pricing and implement cost governance: tagging, budgets,
and rightsizing instances to avoid surprise bills.
☁️ Cloud Computing — Scale Without Heavy Capital Investment
➤ 2.6 Cybersecurity
Cybersecurity protects systems and data from unauthorised access and threats.
Key areas: authentication, access control, encryption, monitoring and incident response.
- ✔ Authentication: Password policies, MFA and identity management (IAM).
- ✔ Network security: Firewalls, IDS/IPS, secure VPNs.
- ✔ Application security: Secure coding, code reviews and dependency scanning.
- ✔ Monitoring & logging: Centralised logs and SIEM for threat detection.
Practical tip: Use the principle of least privilege, keep software patched and run periodic
security audits/pen tests to find vulnerabilities before attackers do.
➤ 2.7 DevOps & Automation
DevOps is a culture and set of practices combining development and operations to release software faster
and more reliably. Automation (CI/CD) and infrastructure-as-code are central.
- ✔ CI/CD: Automated build, test, and deployment pipelines (Jenkins, GitHub Actions).
- ✔ IaC: Terraform, CloudFormation for reproducible infrastructure.
- ✔ Monitoring: Prometheus & Grafana for metrics, ELK stack for logs.
Practical tip: Start small: automate builds and tests first, then expand to deployments.
Maintain version control for both application code and infrastructure definitions.
⚙️ DevOps — Automation for Reliable & Faster Delivery
➤ 2.8 Emerging & Specialized Areas
IT continues to expand into new fields. Notable emerging areas include:
- ✔ Artificial Intelligence & ML: Model training, inference, MLOps.
- ✔ Edge computing: Processing data closer to where it is generated.
- ✔ Blockchain: Decentralised ledgers for immutability and trust.
