Access token :

The default lifetime of an access token is variable. When issued, an access token's default lifetime is assigned a random value ranging between 60-90 minutes (75 minutes on average). 

SAML : 

The default lifetime of the token is 1 hour

VM:

Creating a VM needs VNet, NIC, NSG, Private ,public IP.

NIC is assigned when a new VM created

Transferring data in the form of packets send and receive through NIC 

NSG assigned to the NIC and it a firewall.

To run ASP.NET core application in Linux,

install Kestrel web server in the Linux machine

Publish code to the folder

Copy the folder to the server

Install .Net core framework SDK 3.1

Install Win SCP tool to copy the published files to the Linux VM.

Kestrel web server runs the application locally inside the Linux VM.

If we want to make it publicly available then we need to install NGINX web server.

NGNIX will redirects the request to the http://localhost:5000

Recovery Service vault:

We can take the backup of a vm using this service.

Recovery service vault should be present at same location where the VM is present.

It will take the incremental backup from the server.

We have 3 different backup policies

1) File 2) VM 3) Disk recovery

We can create backup policy according to our requirement.

We can restore the VM from Backup point.

A Recovery Services vault must be in the same location as the virtual machines being protected. If you have virtual machines in multiple regions, create a Recovery Services vault in each region.

Disaster recovery:

VM: Enable this from the VM -> Disaster recovery & choose the resources to create tartget.

Storage Account:

Microsoft recommends RA-GZRS for maximum availability and durability for your applications.

An important part of a disaster recovery plan is preparing to fail over to the secondary endpoint in the event that the primary endpoint becomes unavailable.

AppService:

Backup -> Configure -> choose the details to proceed further.

Sql Server or DB:

Enable Auditing.

Azure Recovery Services contributes to your BCDR strategy:

• Site Recovery service: Site Recovery helps ensure business continuity by keeping business apps and workloads running during outages. Site Recovery replicates workloads running on physical and virtual machines (VMs) from a primary site to a secondary location. When an outage occurs at your primary site, you fail over to secondary location, and access apps from there. After the primary location is running again, you can fail back to it.
• Backup service: The Azure Backup service keeps your data safe and recoverable.

App Service:

We have different app service plans based on our requirement.

Free, Dev/Test, Standard, premium & Isolated.

Azure Functions:

Azure RDS vs Wvd

The basic difference between RDS and WVD is, RDS is based on a server operating system (OS), WVD comes with a desktop OS that is, multi-user Windows 10. WVD is both platform and infrastructure services (PaaS and Iaas). Here the host is a virtual machine (VM), and the rest of the service is PaaS

app service environment vs app service plan

App Service Plan represents the collection of physical resources for the App Service. An App Service Plan can have multiple web apps. ... The App Service Environment on the other hand is a deployment of the Azure App Service into your own Azure Virtual Network, and runs on a separate SKU, which is called Isolated SKU
