Overview
Contoso, Ltd. is a manufacturing company that has 15,000 employees.
The company uses SAP for sales and manufacturing.
Contoso has sales offices in New York and London and manufacturing facilities in Boston and Seattle.
Existing Environment
Active Directory
The network contains an on-premises Active Directory domain named ad.contoso.com. User email addresses use a domain name of contoso.com.
SAP Environment
The current SAP environment contains the following components:
* SAP Solution Manager
* SAP ERP Central Component (SAP ECC)
* SAP Supply Chain Management (SAP SCM)
* SAP application servers that run Windows Server 2008 R2
* SAP HANA database servers that run SUSE Linux Enterprise Server 12 (SLES 12) Problem Statements Contoso identifies the following issues in its current environment:
* The SAP HANA environment lacks adequate resources.
* The Windows servers are nearing the end of support.
* The datacenters are at maximum capacity.
Requirements
Planned Changes
Contoso identifies the following planned changes:
* Deploy Azure Virtual WAN.
* Migrate the application servers to Windows Server 2016.
* Deploy ExpressRoute connections to all of the offices and manufacturing facilities.
* Deploy SAP landscapes to Azure for development, quality assurance, and production.
All resources for the production landscape will be in a resource group named SAPProduction.
Business goals
Contoso identifies the following business goals:
* Minimize costs whenever possible.
* Migrate SAP to Azure without causing downtime.
* Ensure that all SAP deployments to Azure are supported by SAP.
* Ensure that all the production databases can withstand the failure of an Azure region.
* Ensure that all the production application servers can restore daily backups from the last 21 days.
Technical Requirements
Contoso identifies the following technical requirements:
* Inspect all web queries.
* Deploy an SAP HANA cluster to two datacenters.
* Minimize the bandwidth used for database synchronization.
* Use Active Directory accounts to administer Azure resources.
* Ensure that each production application server has four 1-TB data disks.
* Ensure that an application server can be restored from a backup created during the last five days within 15 minutes.
* Implement an approval process to ensure that an SAP administrator is notified before another administrator attempts to make changes to the Azure virtual machines that host SAP.
It is estimated that during the migration, the bandwidth required between Azure and the New York office will be 1 Gbps. After the migration, a traffic burst of up to 3 Gbps will occur.
Proposed Backup Policy
An Azure administrator proposes the backup policy shown in the following exhibit.

Azure Resource Manager Template
An Azure administrator provides you with the Azure Resource Manager template that will be used to provision the production application servers.

SAP HANA Studio -> Administration -> Overview -> CPU Usage.
SAP HANA Studio -> Administration -> Performance -> Load -> [System] CPU.

Load balancers. These are used to distribute traffic to virtual machines in the application-tier subnet. For high availability, use the built-in SAP Web Dispatcher, Azure Load Balancer, or network appliances, depending on the traffic type (such as HTTP or SAPGUI) or the required network services, such as Secure Sockets Layer (SSL) termination.

Infrastructure
Litware currently uses a third-party provider to host a datacenter in Miami and a disaster recovery datacenter in Chicago, IL.
The network contains an Active Directory domain named litware.com. Litware has two third-party applications hosted in Azure.
Litware already implemented a site-to-site VPN connection between the on-premises network and Azure.

20 production servers.
You have 30 non-production servers including five testing servers, five development servers, five quality assurance (QA) servers, and 15 pre-production servers.
Currently, all SAP applications are in the litware.com domain.
Problem Statements
The current version of SAP ECC has a transaction that, when run in batches overnight, takes eight hours to complete. You confirm that upgrading to SAP Business Suite on HANA will improve performance because of code changes and the SAP HANA database platform.
Litware is dissatisfied with the performance of its current hosted infrastructure vendor. Litware experienced several hardware failures and the vendor struggled to adequately support its 24/7 business operations.
Requirements
Business Goals
Litware identifies the following business goals:
* Increase the performance of SAP ECC applications by moving to SAP HANA. All other SAP databases will remain on SQL Server.
* Move away from the current infrastructure vendor to increase the stability and availability of the SAP services.
* Use the new Environment, Health and Safety (EH&S) in Recipe Management function.
* Ensure that any migration activities can be completed within a 48-hour period during a weekend.
Planned Changes
Litware identifies the following planned changes:
* Migrate SAP to Azure.
* Upgrade and migrate SAP ECC to SAP Business Suite on HANA Enhancement Pack 8.
Technical Requirements
Litware identifies the following technical requirements:
* Implement automated backups.
* Support load testing during the migration.
* Identify opportunities to reduce costs during the migration.
* Continue to use the litware.com domain for all SAP landscapes.
* Ensure that all SAP applications and databases are highly available.
* Establish an automated monitoring solution to avoid unplanned outages.
* Remove all SAP components from the on-premises network once the migration is complete.
* Minimize the purchase of additional SAP licenses. SAP HANA licenses were already purchased.
* Ensure that SAP can provide technical support for all the SAP landscapes deployed to Azure.
