Why Cloud Computing:

1. low cost

2. efficient manage

3. scalability

Azure Compute Services:    VM, VM Scale Sets, Kubernetes Service, Azure Batch, Azure Functions, Azure Container instance

Networking: Virtual network, Load balancer, Application Gateway, VPN Gateway, DNS, CDN, DDos Protection, Traffic Manager, ExpressRoute, Azure Firewall

Azure Storage: Blob Storage, File Storage, Queue Storage, Table Storage

Azure Databases: Cosmos Db, SQL DB, Database for MySql, Database for PostgreSQL, 

Web: Azure App Service

IoT: IoT Central, IoT HUB, IoT Edge

Azure Account > Subscriptions > Resource Groups > Resources

Public Cloud	Private Cloud	Hybrid Cloud
No CapEx	Complete control over resources and security	Most flexibility
Quick provisioning/De-provisioning	Hardware must be purchased at the beginning	Owner can determine where to run applications
Pay only for what they use	Owner is responsible for hardware maintenance and updates	Owner security, compliance and legal requirements

Capital Expenditure (CapEx): up front cost of spending money 

Operational Expenditure (Opex) : spending money for service or product now

IaaS	PaaS	SaaS
VM	App Service	Office 365
Servers	IaaS + OS	PaaS + Hosted applications
more flexible	focus on development	pay-as-you-go model

 

Azure Organization Levels:

1. Management Group

2. Subscription (define limits or quotas)

3. Resource Groups (Logical containers) : Azure resource manager - manager layer tat allows you to CRUD resources

4. Resources (VM, Database, etc)

Management Groups: 

• 10000 management groups can be supported
• supported 6 levels of depth
• single parent
• multiple children
