Cloud computing classification/azure classification
Cloud Computing can be classified as two main models
- Deployment model
- Public Cloud
- Private Cloud
- Hybrid Cloud
- Service Model
IaaS: Infrastructure as a service eg: VMs
PaaS: Platform as a service eg: SQL Instance, Web Apps
SaaS: Software as a service eg: O365,Gmail
Microsoft Azure is supporting all the above models
- Azure Service management/Classic – legacy
- Azure Resource Manager
- Azure VMs
- Can be created through by portal as well using the PS script.
- Can create the VM depends on the requirement with the Sku and can scale at any time we want.
- All the VM images will be available in Azure market place also available Linux VM images.
- Microsoft will manage the disk and the network if we are select the managed service disk.
- Microsoft can give the 99.95 % SLA if we are configured the high availability option(Update,Fault domain).
- Storage account is the primary requirement of the VM creation and the storage account name should be globally unique since the endpoint can publish to the internet.
Azure Networking
Address space and the subnet is an integral part of Azure.
In ARM we will be able to create Vnet to Vnet, Site to Site, point to site VPN.
Express route and the VPN connectivity are the two possible way to connect the Azure Infra apart from the Https traffic
Content Delivery Network(CDN) is helpful for the web apps to store the metadata of high memory files.
Azure Networking
We can extend the on premises AD infra to azure with azure AD
AAD connect is helping us to sync the on premises user info to Azure AD
MFA can be enable through Azure AD
