Storage
- Blob storage is a flat structure used for unstructured data (images, videos etc)
- Azure file storage and Azure Data Lake storage are hierarchical file storage similar to SMB shares, both of which you can do shares on
Connectivity
- Azure Express route is more expensive than a site to site VPN
- Azure Express route does not traverse the internet, it's a private connection
- One vnet cannot talk to another vnet unless you create a vnet peer
- For a site to site vpn the "Local Network Gateway" is created in Azure but it refers to the IP address of the on prem router/VPN. The "Virtual Network Gateway" is also created in Azure but this refers to the Azure side of the VPN
- By default all virtual machines get outbound traffic to the internet
- You can divide a vnet up in to subnets and configure routes between them
- If you want inbound traffic from the internet to a vm you must assign a public IP to the vm
Subscriptions
- One subscription can have a max of 980 resource groups
- One subscription can have a max of 50 tags
