What is the advantage to move to cloud?

Flexibility : We can restructure of our Environment is needed and you can create the an number of services based on our requirements.

Pay As you GO : PAY as you go option is good , Only pay for the services you used in a months or Day/Hrs. basis.

Hybrid Capability: We can integrate our on-premises Environment to azure using Site recovery or other Microsoft tool which will help us to extent our data center to azure .

Securing you Data : We can use the azure encryption ,Security center, key vault etc. application for securing the data which is resides in azure.

Scale on Demand : We can scale up the IAAS PASS SAAS services as per our demands.

Example: If customer ask he need 10 servers with in 1 day how we can process or is it possible , Yes it is possible using Windows azure and not even one day we can give it with 1-2 Hours Using the cloud services. If we need to in on-premises it might take 3-4 months to process and configure the server.

Integrative Data Solution: We can integrate the Data solution with azure like SQL server, Bigdata, Visual studio Etc.

Backup : We can directly take the backup in azure storage accounts with minimal charges and no need to buy additional hardware (backup tape HDD, File server etc.).

Disaster Recovery: We can use the Recovery Vault which known as Site recovery vault in azure to do Disaster recovery in azure without any problem.

What is storage account?

Azure Storage is massively scalable, so you can store and process hundreds of terabytes of data to support the big data scenarios required by scientific, financial analysis, and media applications.

• Difference between LRS And ZRS storage Account?
• Locally redundant storage (LRS).Locally redundant storage maintains three copies of your data. LRS is replicated three times within a single data center in a single region. LRS protects your data from normal hardware failures, but not from the failure of a single data center.
• Zone-redundant storage (ZRS).Zone-redundant storage maintains three copies of your data. ZRS is replicated three times across two to three facilities, either within a single region or across two regions, providing higher durability than LRS. ZRS ensures that your data is durable within a single region.
• Create and Manage the Azure storage accounts

What is file  storage ?

File storage offers shared storage for applications using the standard SMB 2.1 or SMB 3.0 protocol. Microsoft Azure virtual machines and cloud services can share file data across application components via mounted shares, and on-premises applications can access file data in a share via the File storage API.

Pre-requisite of  create and  WebApps?

• Azure Subscription.
• Storage account
• SQL Database Connection
• SSL certificate
• Network security Group configuration.
• Custom DNS
• Data source
•  Deployments Credentials if you are using the FTP.
• Deployments Option like Visual Studio Onedrive ,local git etc
• We should know the application version(.net4.5,4.3 python 32bit etc ) while migrating or creating the webapps

What is CDN?

The Microsoft Azure Content Delivery Network (CDN) offers developers a global solution for delivering high-bandwidth content that is hosted in Azure or any other location. Using the CDN, you can cache publicly available objects loaded from Azure blob storage, a web application, virtual machine, application folder, or other HTTP/HTTPS location. The CDN cache can be held at strategic locations to provide maximum bandwidth for delivering content to users. The CDN is typically used for delivering static content such as images, style sheets, documents, files, client-side scripts, and HTML pages.

What azure VPN and how many types of Azure VPN we can configure in azure?

Site to Site VPN :

A Site-to-Site (S2S) VPN gateway connection is a connection over IPsec/IKE (IKEv1 or IKEv2) VPN tunnel. This type of connection requires a VPN device located on-premises that has a public IP address assigned to it and is not located behind a NAT. S2S connections can be used for cross-premises and hybrid configurations

Point to Site VPN: A Point-to-Site (P2S) configuration lets you create a secure connection from an individual client computer to a virtual network. P2S is a VPN connection over SSTP (Secure Socket Tunneling Protocol). Point-to-Site connections are useful when you want to connect to your VNet from a remote location, such as from home or a conference, or when you only have a few clients that need to connect to a virtual network. P2S connections do not require a VPN device or a public-facing IP address. You establish the VPN connection from the client computer.

Vnet to Vnet : Connecting a virtual network to another virtual network (VNet-to-VNet) is similar to connecting a VNet to an on-premises site location. Both connectivity types use a VPN gateway to provide a secure tunnel using IPsec/IKE. You can even combine VNet-to-VNet communication with multi-site connection configurations. This lets you establish network topologies that combine cross-premises connectivity with inter-virtual network connectivity.

Azure Virtual network setup and configuration

Azure Site to site VPN Configuration Step-step

 What is express route?

ExpressRoute is a direct, dedicated connection from your WAN (not over the public Internet) to Microsoft Services, including Azure. Site-to-Site VPN traffic travels encrypted over the public Internet. Being able to configure Site-to-Site VPN and ExpressRoute connections for the same virtual network has several advantages.

You can configure a Site-to-Site VPN as a secure failover path for ExpressRoute, or use Site-to-Site VPNs to connect to sites that are not part of your network, but that are connected through ExpressRoute. Notice that this configuration requires two virtual network gateways for the same virtual network, one using the gateway type ‘Vpn’, and the other using the gateway type ‘ExpressRoute’.

1. How you can troubleshoot if VM is not working?
2. We can reset the VM configuration.
3. If user has forget the password of the VM local account how we can change?

Ans:- you can found the answer here i have provide the information in details:  Windows Azure VM troubleshootings

Is it possible to host the VM in another region and connect to different region?

Yes, We need to setup the interconnectivity while creation the  V-net to V-net  connection between both the region than only we can connect.
