➽As a Network Administrator you are working in your Company.You work for a company named DSR.com.The corporate network consists of physical and virtual servers located in a datacenter and virtual servers hosted on Microsoft Azure.The company has servers that run Windows Server 2008, Windows Server 2008 R2 and Windows Server 2012.The corporate network consists of physical and virtual servers located in a datacenter and a public cloud hosted on Microsoft Azure. The company has a Development department.
Users in the Development department develop custom applications that are used within the company.One custom application is named DsApp1.The application is hosted in Azure Cloud Services.
The developers release an updated version of DsApp1.You need to deploy the updated version of DsApp1 to Azure cloud services for a period of time to allow for testing.
During testing,the current version of DsApp1 must remain online.After testing,the new version must replace the current version as the live version with the minimum amount of downtime.When the new version is live,the old version must remain available for a period of time to be redeployed in the
event of problems with the new version.The solution must minimize costs,administrative effort and application downtime.

SOLUTION:

➧⤵Deploy the new application to the staging area.

  ⤵Perform a Virtual IP swap.
🔼Azure App Service:
An integrated service that enables you to create web apps and mobile apps for any platform or device,easily integrate with SaaS solutions (Office 365,Dynamics CRM,Salesforce,Twilio)
easily connect with on-premises applications (SAP,Oracle,Siebel).
Azure App Services are useful for developers.It offers (Web,API,Mobile and Function )Apps
(that run Azure Functions).These apps are incredibly powerful and can literally get you up and running in minutes.They provide a host of amazing features like (auto)scaling,easy authentication,offline sync (for Mobile Apps),hybrid connections and much more.
                                        SWAP
🔄staging.website.com ⬄  🔁production.website.com
You have a Web App deployed in an Azure App Service and it has a URL like production.website.com.
In Azure App Services,you can very easily add an additional deployment slot.
The deployment slot has a different URL like staging.website.com.
Your users would be accessing your original Web App because that is your production environment slot. 
You can deploy a new version of the Web App into a secondary deployment slot,so you can test it before it goes live.

Instead of deploying your Web App to a staging slot,you could have deployed it as whole new App
Service.The swap functionality of the deployment slot takes care of this.
The original App Service deployment slot is also called the production slot.
Deployment slots have a different URL than the original App Service.This URL is based on the name you give the deployment slot.
For instance, “staging” can become http://azureadministrator.blogspot-staging.azurewebsites.net.
Deployment slots are actually live apps with their own hostnames.App content and configurations
elements can be swapped between two deployment slots, including the production slot.
a)In the Azure Portal,open your app's resource blade.
b)Choose the Deployment slots option,then click on Add Slot.
c)In the Add a slot blade,give the slot a name,and select whether to clone app configuration from
another existing deployment slot.
After you have created several slots,you will be able to clone configuration from a slot other than
the one in production.
d)In your app's resource blade, click Deployment slots,then click a deployment slot to open that slot's
resource blade,with a set of metrics and configuration.
The name of the slot is shown at the top of the blade to remind you that you are viewing the deployment slot.
e)Click the app URL in the slot's blade. Notice the deployment slot has its own hostname and is also a live app.
Suppose that I have a website deployed in a Web App.
This Web App has the custom URL https://azureadministrator.blogspot.com/.I have created a new version of the website and want to test it before publishing it.So,I create a deployment slot called staging.
which has the URL http://azureadministrator.blogspot-staging.azurewebsites.net.
Staging is the concept of testing an application in a production mirrored environment before moving
the site to production.
The same configuration values so that I use the same database and cache as production.I have deployed the new website in the deployment slot and want to deploy to production.I can do this by performing a swap.
a)To swap deployment slots,click the Swap button in the command bar of the app or in the command bar of a deployment slot.
b)Make sure that the swap source and swap target are set properly.
                                      SWAP
🔁staging.website.com  ⬌  🔁production.website.com
After a swap,the “old” website will be in the staging slot and the “new” website in the production
slot.

Connect)
e)Installation of Azure AD Connect
➢Uninstall DirSync (or temporarily disable it)
➢Install Azure AD Connect
➢Optionally begin synchronization
➤Additional steps:-
➭You are currently using Full SQL Server - local or remote.
➭You have more than 50,000 objects in scope for synchronization.

➥DirSync (Directory Synchronization) is a tool for making copies of a local directory in a hybrid cloud deployment of Microsoft Exchange.DirSync works with Office 365 and Windows Azure Active Directory,removing the need for Active Directory Federation Services in many organizations.
Install Azure AD Connect on separate server.When you install Azure AD Connect on a new server,the assumption is that you want to perform a clean install of Azure AD Connect.Since you want to use the DirSync configuration,there are some extra steps to take Run the Azure AD Connect installer (MSI).
🔼After the installation of Dirsync,run miisclient.exe to create directory partitions.

The on-premise Active Directory contains many Organizational Units (OUs).User accounts are located in multiple OUs.You have configured Directory Synchronization (DirSync) to synchronize user accounts in selected OUs to Azure Active Directory and performed an initial user account synchronization.You find some user accounts in OUs that are excluded from synchronization that need to be synchronized to Azure AD.You move the user accounts to an OU that is included in the synchronization schedule.You discover that the users are unable to log in to Office 365.You confirm that the user accounts exist in Azure AD.However,event log error messages indicate a problem with password synchronization for the moved user accounts.
