– Use platform as a service (PaaS) offerings whenever possible and avoid having to provision virtual machines that must be managed by Litware.

– Ensure that the analytical data store is accessible only to the company’s on-premises network and Azure services.

– Use Azure Active Directory (Azure AD) authentication whenever possible.

– Use the principle of least privilege when designing security.

– Stage inventory data in Azure Data Lake Storage Gen2 before loading the data into the analytical data store. Litware wants to remove transient data from Data Lake Storage once the data is no longer in use. Files that have a modified date that is older than 14 days must be removed.

– Limit the business analysts’ access to customer contact information, such as phone numbers, because this type of data is not analytically relevant.

– Ensure that you can quickly restore a copy of the analytical data store within one hour in the event of corruption or accidental deletion.

Requirements. Planned Environment

Litware plans to implement the following environment:

– The application development team will create an Azure event hub to receive real-time sales data, including store number, date, time, product ID, customer loyalty number, price, and discount amount, from the point of sale (POS) system and output the data to data storage in Azure.

– Customer data, including name, contact information, and loyalty number, comes from Salesforce and can be imported into Azure once every eight hours. Row modified dates are not trusted in the source table.

– Product data, including product ID, name, and category, comes from Salesforce and can be imported into Azure once every eight hours. Row modified dates are not trusted in the source table.

– Daily inventory data comes from a Microsoft SQL server located on a private network.

– Litware currently has 5 TB of historical sales data and 100 GB of customer data. The company expects approximately 100 GB of new data per month for the next year.

– Litware will build a custom application named FoodPrep to provide store employees with the calculation results of how many prepared food items to produce every four hours.

– Litware does not plan to implement Azure ExpressRoute or a VPN between the on-premises network and Azure.
