Core concepts and lessons

1) Cloud computing fundamentals

• Definition: On-demand delivery of compute, storage, networking, apps and analytics over the internet.
• Key benefits: cost efficiency (pay-for-use), scalability, global access, reliability (redundancy), security/compliance.
• Cloud characteristics: on‑demand self‑service, broad network access, resource pooling, rapid elasticity, measured/metered services.

2) Cloud service models

• IaaS (Infrastructure as a Service)
  • What: VMs, storage, networking (e.g., Azure VMs, Azure Storage).
  • Use cases: website hosting, dev/test, disaster recovery, HPC.
  • Responsibility: customer controls OS/apps; provider manages infra.
• PaaS (Platform as a Service)
  • What: Platform for development & deployment (e.g., Azure App Service, Azure SQL).
  • Use cases: rapid app development, data analytics, IoT backends, API management.
  • Responsibility: provider manages OS/infrastructure; developer focuses on code.
• SaaS (Software as a Service)
  • What: Ready-to-use apps over internet (e.g., Microsoft 365: Word, Excel, Teams, OneDrive).
  • Use cases: email/collaboration, CRM, BI dashboards.
  • Responsibility: provider manages application and infra; customer uses app and configures settings.

3) Cloud deployment models

• Public cloud: shared infrastructure (Azure, AWS, GCP) — cost-effective, scalable.
• Private cloud: dedicated to one organization — greater control & security.
• Hybrid cloud: combination of public + private — flexibility, data locality.
• Community cloud: shared by organizations with common requirements (e.g., government, healthcare).

4) Shared responsibility model

• Provider responsibilities: security of the cloud (physical infrastructure, host, network), hardware maintenance, platform reliability and compliance.
• Customer responsibilities: security in the cloud (data, identity, access, configuration), application-level controls and user access management.
• Example: In Microsoft 365 (SaaS), Microsoft ensures app availability/security; customer must manage user access & data protection.

5) Consumption-based pricing

• Pay only for resources consumed (compute hours, storage GB) — reduces capex, improves budgeting, enables dynamic scaling.
• Azure examples: VMs billed by runtime hours, blob storage billed by usage.

6) Availability, reliability, scalability & manageability

• High availability via redundancy, failover, geographic replication and automatic failover.
• Scalability via autoscaling to meet demand (cost efficiency & performance).
• Predictability: SLAs (e.g., 99.99%), cost predictability via subscription/usage models.
• Security & governance: encryption, identity controls (Azure AD / Entra ID), threat detection (Defender), compliance frameworks (GDPR, ISO).
• Manageability: centralized portals (Microsoft 365 admin center, Azure Portal), automation (Power Automate, Azure Automation), monitoring (Azure Monitor, Microsoft Sentinel) and reporting.

7) Microsoft 365 vs Office 365

• Office 365: suite of cloud productivity apps (Word, Excel, PowerPoint, Outlook, Teams).
• Microsoft 365: Office 365 plus intelligent cloud services, device management (Intune/Endpoint Manager), advanced security (Defender, Conditional Access), and OS licenses in some SKUs — a broader platform for modern/hybrid work.

8) Microsoft 365 tenant basics and setup

• Tenant: an organization’s dedicated Microsoft 365 instance (identity, services, data, licensing).
• Basic setup steps:
  1. Register domain name.
  2. Create user accounts.
  3. Assign licenses.
  4. Configure services (Exchange Online, SharePoint, Teams, OneDrive).
  5. Set security policies (MFA, conditional access) and compliance settings.
• Admin tools: Azure AD / Entra ID, Admin Center, Service Health, Compliance Center.

9) Productivity & collaboration apps

• Core apps: Word, Excel, PowerPoint, Outlook, OneNote (cloud co-authoring, AI features).
• Work management: Teams (hub for chat, meetings, files), Planner, To-Do, Project, Power Automate.
• Additional apps: OneDrive, SharePoint, Stream (video), Power BI (analytics), Forms.
• Collaboration: real-time co-authoring, Teams channels, file storage in OneDrive/SharePoint, integrations with Power Platform.

• Hybrid identity: integrates on-prem AD with Entra ID (password hash sync, pass-through auth, federation).
• External identities: guest access, B2B/B2C scenarios, self-service sign-up, conditional access for guests.

14) Access management & Zero Trust

• Conditional Access: policies that consider user, device, location and risk signals; can require MFA, block access or limit resources.
• Global secure access / Security Service Edge (SSE): identity + network protections (secure web gateway, zero-trust network access).
• RBAC and Entra roles: predefined & custom roles, role assignments, Privileged Identity Management for just-in-time elevation and periodic role reviews.
