One Company, Two Clouds

Episode 1

Why Not Just Buy Servers?

AZ-900 cloud concepts: the shared responsibility model, cloud service models (IaaS, PaaS, SaaS), deployment models (public, private, hybrid), consumption-based pricing, and the core benefits of cloud — elasticity, scalability, agility, and moving capital expense to operating expense.

Episode 2

A Home in Azure

AZ-900 Azure architecture and services: the resource hierarchy (subscription, resource group, resource), regions and availability zones, compute choices (VM, containers, serverless), object storage with redundancy (local, zone, geo) and access tiers (hot, cool, archive), private connectivity, and co-locating chatty resources.

Episode 3

Who Gave Them Access?

AZ-900 identity, access and security: identities vs roles vs scope, authentication vs authorisation, multi-factor authentication, role-based access control (RBAC), least privilege, Zero Trust, defence in depth, and using positive and negative access tests to prove a change.

Episode 4

The Bill Has a Plot Twist

AZ-900 management and governance: cost drivers, tags, budgets and budget alerts, the difference between Cost analysis, Advisor, Service Health and Monitor, governance through policy, and infrastructure as code (deployment templates).

Episode 5

Meet SignalNest

CLF-C02 cloud concepts and technology: the value of cloud (agility, not rewriting what works), comparing provider terminology without assuming equivalence, AWS global infrastructure (regions, availability zones, edge locations), migration as a deliberate decision, integration boundaries, and Well-Architected thinking.

Episode 6

The Other Cloud Console

CLF-C02 technology and services: AWS compute (EC2, Lambda, containers), object storage and storage classes (S3), databases (RDS relational, DynamoDB key-value), networking (VPC, DNS, CDN), load distribution, event-driven routes, and distinguishing managed services from learner-owned responsibilities.

Episode 7

An IAM Policy Walks into a Bucket

CLF-C02 security and compliance: the shared responsibility model for security, IAM policy evaluation (default deny, explicit allow, explicit deny wins), least-privilege policy scoping, root-account protection, encryption at rest and in transit, audit logs as evidence, and who owns which control.

Episode 8

Two Clouds, One Budget

CLF-C02 billing, pricing and support: purchase models (on-demand, savings plans / reserved, spot), budgets and cost tools, organisations and consolidated billing, support plan tiers, and reasoning about multi-cloud cost and resilience honestly.
