+- ### Introduction to cloud computing
+	- Define cloud computing.
+		- Compute Power
+		- Storage
+		- Pay only ressources you use
+		- Upkeep is done by cloud provider
+	- Describe the shared responsibility model.
+		- Cloud Provider: Physical security, power, cooling, and network connectivity are the responsibility
+		- Consumer: responsible for the data and information stored in the cloud.
+		- IAAS (Infrastructure)-> PAAS (Platform) -> SAAS (Software)
+		- ![Diagram showing the responsibilities of the shared responsibility model.](https://learn.microsoft.com/en-us/training/wwl-azure/describe-cloud-compute/media/shared-responsibility-b3829bfe.svg){:height 231, :width 700}
+	- Define cloud models, including public, private, and hybrid.
+		- | **Public cloud** | **Private cloud** | **Hybrid cloud** |
+		  | ---- | ---- | ---- |
+		  | No capital expenditures to scale up | Organizations have complete control over resources and security | Provides the most flexibility |
+		  | Applications can be quickly provisioned and deprovisioned | Data is not collocated with other organizations’ data | Organizations determine where to run their applications |
+		  | Organizations pay only for what they use | Hardware must be purchased for startup and maintenance | Organizations control security, compliance, or legal requirements |
+		  | Organizations don’t have complete control over resources and security | Organizations are responsible for hardware maintenance and updates |  |
+		- Azure ARC
+			- Manage Cloud environment
+	- Identify appropriate use cases for each cloud model.
+	- Describe the consumption-based model.
+		- Capital expenditure (CapEx)
+			- upfront one time expenditure
+		- Operational expenditure (OpEx)
+			- spending money on services or products over time
+			- Cloud computing is here
+	- Compare cloud pricing models.
+		- pay-as-you-go pricing model
+- ### Describe the benefits of using cloud services
+	- Describe the benefits of high availability and scalability in the cloud.
+		- uptime (or availability)
+		- demand (or scale)
+		- each Service has own SLA
+	- Describe the benefits of reliability and predictability in the cloud.
+	- Describe the benefits of security and governance in the cloud.
+	- Describe the benefits of manageability in the cloud.
