Overview

Existing Environment

Contoso, Ltd. is a financial data company that has 100 employees. The company delivers financial data to customers.



Active Directory

Contoso has a hybrid Azure Active Directory (Azure AD) deployment that syncs to on-premises Active Directory.



Database Environment

Contoso has SQL Server 2017 on Azure virtual machines shown in the following table.





SQL1 and SQL2 are in an Always On availability group and are actively queried. SQL3 runs jobs, provides historical data, and handles the delivery of data to customers.

The on-premises datacenter contains a PostgreSQL server that has a 50-TB database.



Current Business Model

Contoso uses Microsoft SQL Server Integration Services (SSIS) to create flat files for customers. The customers receive the files by using FTP.



Requirements

Planned Changes

Contoso plans to move to a model in which they deliver data to customer databases that run as platform as a service (PaaS) offerings. When a customer establishes a service agreement with Contoso, a separate resource group that contains an Azure SQL database will be provisioned for the customer. The database will have a complete copy of the financial data. The data to which each customer will have access will depend on the service agreement tier. The customers can change tiers by changing their service agreement.

The estimated size of each PaaS database is 1 TB.

Contoso plans to implement the following changes:

Move the PostgreSQL database to Azure Database for PostgreSQL during the next six months.

Upgrade SQL1, SQL2, and SQL3 to SQL Server 2019 during the next few months.

Start onboarding customers to the new PaaS solution within six months.



Business Goals

Contoso identifies the following business requirements:

Use built-in Azure features whenever possible.

Minimize development effort whenever possible.

Minimize the compute costs of the PaaS solutions.

Provide all the customers with their own copy of the database by using the PaaS solution. Provide the customers with different table and row access based on the customer’s service agreement.

In the event of an Azure regional outage, ensure that the customers can access the PaaS solution with minimal downtime. The solution must provide automatic failover.

Ensure that users of the PaaS solution can create their own database objects but he prevented from modifying any of the existing database objects supplied by Contoso.



Technical Requirements

Contoso identifies the following technical requirements:

Users of the PaaS solution must be able to sign in by using their own corporate Azure AD credentials or have Azure AD credentials supplied to them by Contoso. The solution must avoid using the internal Azure AD of Contoso to minimize guest users.

All customers must have their own resource group, Azure SQL server, and Azure SQL database. The deployment of resources for each customer must be done in a consistent fashion.

Users must be able to review the queries issued against the PaaS databases and identify any new objects created.

Downtime during the PostgreSQL database migration must be minimized.



Monitoring Requirements

Contoso identifies the following monitoring requirements:

Notify administrators when a PaaS database has a higher than average CPU usage.

Use a single dashboard to review security and audit data for all the PaaS databases.

Use a single dashboard to monitor query performance and bottlenecks across all the PaaS databases.

Monitor the PaaS databases to identify poorly performing queries and resolve query performance issues automatically whenever possible.



PaaS Prototype

During prototyping of the PaaS solution in Azure, you record the compute utilization of a customer’s Azure SQL database as shown in the following exhibit.







Role Assignments

For each customer’s Azure SQL Database server, you plan to assign the roles shown in the following exhibit.







HOTSPOT

You are evaluating the role assignments.

For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.

Overview

ADatum Corporation is a retailer that sells products through two sales channels: retail stores and a website.



Existing Environment

ADatum has one database server that has Microsoft SQL Server 2016 installed. The server hosts three mission-critical databases named SALESDB, DOCDB, and REPORTINGDB.

SALESDB collects data from the stores and the website.

DOCDB stores documents that connect to the sales data in SALESDB. The documents are stored in two different JSON formats based on the sales channel.

REPORTINGDB stores reporting data and contains several columnstore indexes. A daily process creates reporting data in REPORTINGDB from the data in SALESDB. The process is implemented as a SQL Server Integration Services (SSIS) package that runs a stored procedure from SALESDB.

Planned Changes

ADatum plans to move the current data infrastructure to Azure.

The new infrastructure has the following requirements:

✑ Migrate SALESDB and REPORTINGDB to an Azure SQL database.

✑ Migrate DOCDB to Azure Cosmos DB.

✑ The sales data, including the documents in JSON format, must be gathered as it arrives and analyzed online by using Azure Stream Analytics. The analytics process will perform aggregations that must be done continuously, without gaps, and without overlapping.

✑ As they arrive, all the sales documents in JSON format must be transformed into one consistent format.

✑ Azure Data Factory will replace the SSIS process of copying the data from SALESDB to REPORTINGDB.



Technical Requirements

The new Azure data infrastructure must meet the following technical requirements:

✑ Data in SALESDB must encrypted by using Transparent Data Encryption (TDE). The encryption must use your own key.

✑ SALESDB must be restorable to any given minute within the past three weeks.

✑ Real-time processing must be monitored to ensure that workloads are sized properly based on actual usage patterns.

✑ Missing indexes must be created automatically for REPORTINGDB.

✑ Disk IO, CPU, and memory usage must be monitored for SALESDB.
