Course contents
01Cloud basicsBasic
What is the cloud?
Renting computing on demand instead of owning machines.
Service models: IaaS, PaaS, SaaS
How much the provider runs, and how much you do.
Regions, zones and latency
Where your resources physically sit, and why it decides both speed and survival.
02The building blocksBasic
Compute: machines, containers, functions
Four ways to run code, and what each costs you in control and idle time.
Storage: objects, blocks and databases
Three storage shapes with genuinely different guarantees.
Networking: VPCs, subnets and load balancers
How traffic reaches your service, and how the pieces reach each other.
03Identity and responsibilityBasic
Identity and access management
Who may do what — the control plane every other control depends on.
The shared responsibility model
What the provider secures, what you secure, and the gap in between.
04Running services safelyAdvanced
Isolation and networking
Private networks and boundaries that keep tenants and systems apart.
Deploying safely
Hardening, least privilege and controlled egress for anything you run.
05Scale and reliabilityAdvanced
Scaling
Bigger machines, more machines, and the bottleneck that moves.
Reliability and recovery
Redundancy, backups, and the two numbers that define what you are promising.
06Operating the platformAdvanced
Infrastructure as code
Describing infrastructure in files, so it can be reviewed, repeated and undone.
Observability
Logs, metrics and traces — and knowing which question each answers.
Deployment strategies
Shipping changes without an outage, and being able to undo them.
Cost management
Where cloud bills actually come from, and how to keep them accountable.
