D: Time Series Insights is a fully managed service for time series data. In this architecture, Time Series Insights performs the roles of stream processing, data store, and analytics and reporting. It accepts streaming data from either IoT Hub or Event Hubs and stores, processes, analyzes, and displays the data in near real time.
C: The processed data is stored in an analytical data store, such as Azure Data Explorer, HBase, Azure Cosmos DB, Azure Data Lake, or Blob Storage.

Data Warehouse: Azure Synapse Analytics (formerly SQL Data Warehouse)
Azure Synapse Analytics is a massively parallel processing (MPP) data warehouse that can handle large amounts of data and provides a scalable solution for analytics.
Managed Serving Layer: Azure Analysis Services
Azure Analysis Services provides a fully managed platform-as-a-service (PaaS) solution for online analytical processing (OLAP) and data modeling. It is suitable for serving analytical models to thousands of end users.

Azure Storage Mover is a fully managed, hybrid migration service designed to move on-premises file shares to Azure Blob Storage and Azure Files. It simplifies the process of migrating large volumes of data by automating the transfer and supporting various source types.
You can use Storage Mover for different migration scenarios such as lift-and-shift, and for migrations that you have to repeat regularly. Azure Storage Mover also helps maintain oversight and manage the migration of all your globally distributed file shares from a single storage mover resource.
Supported sources and targets
The current Azure Storage Mover release supports full-fidelity migrations for specific source- target pair combinations. Always utilize the latest agent version to benefit from these supported sources and destinations:
* SMB 2.x mount
Azure file share (SMB)
SMB 1.x sources and NFS Azure file shares are currently not supported.
*-> NFS 3 & 4 mount
Azure blob storage container
Containers with the "Hierarchical Namespace Service (HNS)" feature enabled, are supported and the ADLS Gen2 REST API set is used for migration.

Explanation:
Box 1: SQL Server on Azure Virtual Machines
Project1: A rapidly iterating cloud-based solution that integrates multiple Azure software as a service (SaaS) solutions Requirements:
Minimize costs.
Minimize administrative effort associated with operating system administration.
In Azure, you can have your SQL Server workloads running as a hosted service (PaaS), or a hosted infrastructure (IaaS) supporting the software layer, such as Software-as-a-Service (SaaS) or an application.
SQL Server on Azure Virtual Machines is a fast and straightforward migration infrastructure as a service (IaaS) option, but it requires a more hands-on approach to database administration.
Box 2: Azure SQL Managed instance
Project2: The migration of a 5-TB on-premises database to Azure
Requirements:
Minimize how long it takes to migrate the database.
Minimize administrative effort associated with operating system updates and backups.
SQL Managed Instance supports database migration from on-premises with minimal to no database changes.
Maximum database size: Up to 16 TB.
Azure SQL Managed Instance falls into the industry category of Platform-as-a-Service (PaaS), and is best for most migrations to the cloud. SQL Managed Instance is a collection of system and user databases with a shared set of resources that is lift-and-shift ready.
Box 3: Azure SQL Database
Project3: The migration of a 30-TB on-premises database to Azure
Requirements:
Minimize how long it takes to migrate the database.
Minimize administrative effort associated with operating system updates and backups.
Azure SQL Databases of up to 128 TB.
Migration from SQL Server might be challenging.
Compatibility with the SQL Server version can be achieved only using database compatibility levels.
